[0097] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0098] The following is for reference. Figures 1-20 A cam follower assembly 100 according to an embodiment of the present invention is described.

[0099] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18 According to a first aspect embodiment of the present invention, a cam mechanism 300 includes a cam body 200, a cam follower assembly 100, and a lubrication mechanism. The cam body 200 is provided with a guide groove 62, and the cam follower assembly 100 cooperates with the guide groove 62. The lubrication mechanism is used to lubricate the cooperation between the cam body 200 and the cam follower assembly 100. Through the cooperation between the cam follower assembly 100 and the guide groove 62, the guide groove 62 can guide the movement of the cam follower assembly 100, ensuring that the cam follower assembly 100 moves along a predetermined trajectory and a predetermined direction. For example, the cam follower assembly 100 can move along the axial direction of the cam body 200 (see, for example, reference...). Figure 3 The movement can be in the e1 direction or in other directions along the cam body 200.

[0100] For example, the cam body 200 is rotatable, and the rotation of the cam body 200 can drive the cam follower assembly 100 to move. The cam follower assembly 100 can convert the rotation of the cam body 200 into axial movement along the cam body 200.

[0101] When the cam follower assembly 100 moves relative to the cam body 200, there is friction between the cam follower assembly 100 and the inner wall of the guide groove 62. A lubrication mechanism is used to lubricate the mating area between the cam body 200 and the cam follower assembly 100. This provides lubrication for the mating between the cam follower assembly 100 and the cam body 200, making the relative movement between the cam follower assembly 100 and the cam body 200 smoother and reducing frictional wear between the cam follower assembly 100 and the cam body 200.

[0102] According to an embodiment of the present invention, the cam mechanism 300 is provided with a lubrication mechanism for lubricating the mating area between the cam body 200 and the cam follower 20. When the cam follower assembly 100 and the cam body 200 move relative to each other, the lubrication mechanism can provide lubrication to the mating area between the cam body 200 and the cam follower assembly 100, so that the relative movement between the cam follower assembly 100 and the cam body 200 is smoother and the friction and wear between the cam follower assembly 100 and the cam body 200 can be reduced, thereby helping to extend the overall service life of the cam mechanism 300.

[0103] Reference Figure 3 , Figure 4 and Figure 13 According to some embodiments of the present invention, the lubrication mechanism includes an oil reservoir 30 and an oil delivery channel 23. The oil reservoir 30 delivers lubricating medium to the mating point between the cam body 200 and the cam follower assembly 100 through the oil delivery channel 23. The oil reservoir 30 can store lubricating medium to ensure a long-term supply of lubricating medium. The oil delivery channel 23 can deliver lubricating medium from the oil reservoir 30 to the mating point between the cam body 200 and the cam follower assembly 100. When the cam follower assembly 100 and the cam body 200 move relative to each other, the lubricating medium can provide lubrication between the cam follower assembly 100 and the inner wall of the guide groove 62, so as to make the relative movement between the cam follower assembly 100 and the cam body 200 smoother and reduce frictional wear between the cam follower assembly 100 and the cam body 200.

[0104] Optionally, the lubrication mechanism includes an oil delivery channel 23, which may be formed on the cam follower assembly 100 or on the cam body 200. The oil delivery channel 23 may also be a separately provided oil pipe.

[0105] Reference Figures 1-3According to some embodiments of the present invention, the oil reservoir 30 is installed on the cam follower assembly 100, which can make full use of the space of the cam follower assembly 100, making the overall structure of the lubrication mechanism and the cam follower assembly 100 more compact and reducing the space occupied by the oil delivery channel 23. In this way, when the cam follower assembly 100 and the cam body 200 move relative to each other, the oil reservoir 30 can deliver the lubricating medium to the mating point between the cam body 200 and the cam follower assembly 100 more directly and efficiently.

[0106] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, an oil delivery channel 23 is formed on the cam follower assembly 100. Since the oil reservoir 30 is mounted on the cam follower assembly 100, and the oil delivery channel 23 is directly formed on the cam follower assembly 100, the delivery path of the lubricating medium can be shortened, allowing the lubricating medium to reach the mating point between the cam body 200 and the cam follower assembly 100 more quickly. Furthermore, integrating the oil delivery channel 23 onto the cam follower assembly 100 reduces the use of external oil delivery pipes, thus making the overall structure of the lubrication mechanism and the cam follower assembly 100 more compact and reducing the occupancy of external space.

[0107] Reference Figure 3 , Figure 4 and Figure 16 According to some embodiments of the present invention, the oil reservoir 30 is provided with a connecting joint 40, and the cam follower assembly 100 is provided with a mounting hole 24. The connecting joint 40 is accommodated in the mounting hole 24, and a flow channel 44 is formed in the connecting joint 40, which connects the storage cavity 31 of the oil reservoir 30 and the oil delivery channel 23. The mounting hole 24 facilitates the accommodation of the connecting joint 40, making the assembly between the oil reservoir 30 and the follower assembly more convenient, and also making the overall structure of the oil reservoir 30 and the follower assembly more compact. For example, by connecting the storage cavity 31 and the oil delivery channel 23 through the flow channel 44, the lubricating medium in the storage cavity 31 can flow to the oil delivery channel 23 through the flow channel 44.

[0108] Reference Figures 15-16 According to some embodiments of the present invention, the flow channel 44 is formed as a Tesla valve structure. Due to the unidirectional flow of the Tesla valve structure, the flow path of the lubricating medium in the storage cavity 31 through the flow channel 44 toward the oil delivery channel 23 is unidirectional, which can reduce or avoid the possibility of the lubricating medium flowing back into the storage cavity 31, thereby improving the lubrication effect on the cam follower assembly 100.

[0109] Reference Figure 3 , Figure 4 and Figure 16According to some embodiments of the present invention, the connecting joint 40 is threadedly connected to the mounting hole 24, which makes the connection between the oil reservoir 30 and the cam follower assembly 100 simple and has strong stability.

[0110] Reference Figure 3 , Figure 4 and Figure 14 According to some embodiments of the present invention, the mounting hole 24 includes a first hole segment 241 and a second hole segment 242 arranged along the axial direction of the mounting hole 24. A first limiting step surface 243 is formed between the first hole segment 241 and the second hole segment 242. The connecting joint 40 includes a first connecting segment 41 and a second connecting segment 42 arranged along the axial direction of the connecting joint 40. A second limiting step surface 43 is formed between the first connecting segment 41 and the second connecting segment 42. The first connecting segment 41 is accommodated in the first hole segment 241. The second limiting step surface 43 is located in the first hole segment 241 and abuts against the first limiting step surface 243 in the axial direction of the mounting hole 24. The second connecting segment 42 is accommodated in the second hole segment 242. The first connecting section 41 is accommodated in the first hole section 241 and the second connecting section 42 is accommodated in the second hole section 242, which facilitates the installation of the connecting joint 40 at the mounting hole 24, thereby making the assembly between the cam follower assembly 100 and the oil reservoir 30 more convenient and allowing for a more compact overall structure of the cam follower assembly 100 and the oil reservoir 30. The abutment between the second limiting step surface 43 and the first limiting step surface 243 in the axial direction of the mounting hole 24 ensures accurate positioning of the cam follower assembly 100 and the oil reservoir 30.

[0111] Reference Figure 4 , Figure 13 and Figure 16 According to some embodiments of the present invention, the second connecting segment 42 is threadedly connected to the second hole segment 242, which makes the connection between the second connecting segment 42 and the second hole segment 242 simple and has strong stability.

[0112] Reference Figure 3 , Figure 4 and Figure 13 According to some embodiments of the present invention, the cam follower assembly 100 has a receiving space 114, and the oil reservoir 30 is located in the receiving space 114. The receiving space 114 facilitates the receiving of the oil reservoir 30 and allows the oil reservoir 30 and the cam follower assembly 100 to have a compact overall structure.

[0113] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18According to some embodiments of the present invention, the cam follower assembly 100 includes a transmission member 10 and a cam follower 20. The cam follower assembly 100 cooperates with the guide groove 62. The cam follower 20 is connected to the transmission member 10 to drive the transmission member 10 to move along the axial direction of the cam body 200. The oil reservoir 30 is connected to the cam follower 20. The cam follower 20 forms an oil delivery channel 23. The rotation of the cam body 200 can drive the cam follower 20 to move. Through the connection between the cam follower 20 and the transmission member 10, the cam follower 20 can convert the rotational motion of the cam body 200 into the linear motion of the transmission member 10, realizing the linear motion of the transmission member 10 along the axial direction of the cam body 200. This realizes the power transmission process between the cam body 200 and the transmission member 10.

[0114] Reference Figure 3 , Figure 4 and Figure 18 According to some embodiments of the present invention, the cam follower 20 includes a first mating part 211 and a second mating part 212. The first mating part 211 mates with the guide groove 62, and the second mating part 212 is connected to the transmission member 10 to drive the transmission member 10 to move along the axial direction of the cam body 200. The oil reservoir 30 is connected to the second mating part 212. Through the mating of the first mating part 211 with the guide groove 62, the rotation of the cam body 200 can drive the first mating part 211 to move. The movement of the first mating part 211 can drive the movement of the second mating part 212. Through the connection of the second mating part 212 with the transmission member 10, the movement of the second mating part 212 can drive the movement of the transmission member 10, thereby realizing the power transmission process between the cam body 200 and the transmission member 10.

[0115] Reference Figure 3 , Figure 4 and Figure 16 According to some embodiments of the present invention, the oil storage component 30 is provided with a connecting joint 40, an oil delivery channel 23 is formed in the first mating part 211, and an installation hole 24 is provided in the second mating part 212. The connecting joint 40 is accommodated in the installation hole 24, and a flow channel 44 is formed in the connecting joint 40. The flow channel 44 connects the storage cavity 31 of the oil storage component 30 and the oil delivery channel 23, which makes the overall structure of the connecting joint 40 and the second mating part 212 compact. By having the connecting joint 40 accommodated in the installation hole 24, the oil delivery channel 23 is formed in the first mating part 211, and the flow channel 44 connecting the storage cavity 31 and the oil delivery channel 23 is formed in the connecting joint 40, the lubricating medium in the storage cavity 31 can flow more conveniently into the oil delivery channel 23.

[0116] Reference Figure 1 , Figure 3 and Figure 16According to some embodiments of the present invention, the oil reservoir 30 can move together with the cam follower 20. The lubricating medium inside the oil reservoir 30 will flow out from the oil reservoir 30 and flow to the oil delivery channel 23 due to its own rotation. The automatic oil discharge function of the oil reservoir 30 is realized by utilizing the rotation of the oil reservoir 30. This can simplify the structure of the oil reservoir 30 and save manufacturing costs compared to the automatic oil discharge function of the oil reservoir 30 controlled by an electronic control module.

[0117] In some embodiments, the oil reservoir 30 is a rubber component. Rubber components have good elasticity, softness, and sealing properties, and can effectively store lubricating media. By using a rubber component for the oil reservoir 30, the softness of rubber can provide a buffering effect between the contact surfaces. When the cam follower 20 drives the oil reservoir 30 to roll, the frictional wear when the oil reservoir 30 is in direct contact with the inner wall of the accommodating space 114 can be reduced.

[0118] Reference Figure 1 , Figure 2 and Figure 5 According to some embodiments of the present invention, the transmission component 10 includes two connecting portions 11 arranged opposite to each other and spaced apart. Two cam followers 20 are also arranged opposite to each other, with each cam follower 20 corresponding to one of the two connecting portions 11, and each cam follower 20 connected to its corresponding connecting portion 11. By having two cam followers 20 arranged opposite to each other and corresponding to the two opposite connecting portions 11, the contact stress between the cam follower 20 and the cam can be dispersed, thereby reducing the wear on a single cam follower 20 and extending its service life.

[0119] In some embodiments, there are two cam followers 20 arranged opposite each other. Guide grooves 62 are formed on the inner peripheral wall of the cam body 200 and are arranged opposite each other. The two guide grooves 62 respectively cooperate with the cam follower 20. The extension trajectory of the guide grooves 62 is a spiral. By having two guide grooves 62 arranged opposite each other and cooperating with two cam followers 20 respectively, the cam follower 20 can be driven to move along the extension trajectory of the guide grooves 62 in a better way, and the contact stress between the cam follower 20 and the cam body 200 can be better dispersed.

[0120] In some embodiments, the cam body 200 is a cylindrical cam body 200, and a mounting cavity 61 is formed in the cam body 200. The cam follower assembly 100 is located in the mounting cavity 61, and a guide groove 62 is formed in the inner peripheral wall of the mounting cavity 61. The mounting cavity 61 can facilitate the cam follower assembly 100 to be accommodated therein, so that the overall structure of the cam mechanism 300 is more compact. By forming the guide groove 62 in the inner peripheral wall of the mounting cavity 61, it is convenient for the two cam followers 20 arranged opposite to each other to cooperate with the guide groove 62.

[0121] Reference Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present invention, there are two oil reservoirs 30, each corresponding to one of the two cam followers 20. Each oil reservoir 30 delivers lubricating medium to the mating area between the cam body 200 and the cam follower 20 through the oil delivery channel 23 within the corresponding cam follower assembly 100. The correspondence between the two oil reservoirs 30 and the two cam followers 20 further improves the lubrication effect at the mating area between the cam body 200 and the cam follower 20, effectively reducing friction and wear between them.

[0122] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, a receiving space 114 is formed on the transmission member 10. The receiving space 114 is located between two connecting portions 11, and the oil reservoir 30 is located within the receiving space 114. The cam follower 20 is located on the side of the receiving space 114 closer to the cam body 200. This makes full use of the space in the radial direction of the transmission member 10, so that the connecting portions 11, the receiving space 114, and the oil reservoir 30 are arranged in an orderly manner, and the overall structure of the connecting portions 11, the receiving space 114, and the oil reservoir 30 is compact. By placing the receiving space 114 between the two connecting portions 11, the distance between the receiving space 114 and the two cam followers 20 can be relatively close, thereby making the distance between the oil reservoir 30 and the two cam followers 20 relatively close, so that the lubricating medium in the oil reservoir 30 in the receiving space 114 can enter the oil delivery channel 23 of the two cam followers 20.

[0123] Reference Figure 3 , Figure 4 and Figure 18 According to some embodiments of the present invention, the cam follower 20 is movable relative to the transmission member 10. The rotation of the cam body 200 can drive the cam follower 20 to move. Since the cam follower 20 is movable relative to the transmission member 10, the cam follower 20 can convert the rotational motion of the cam body 200 into the linear motion of the transmission member 10, so as to drive the transmission member 10 to move linearly along the axial direction of the cam body 200. In this way, the power transmission process between the cam body 200 and the transmission member 10 can be realized.

[0124] Reference Figure 3 , Figure 4 and Figure 18 According to some embodiments of the present invention, the cam follower 20 can be positioned relative to the transmission member 10 about its own central axis (e.g., refer to...). Figure 3The central axis g) rotates. By rotating the cam follower 20 relative to the transmission member 10 around its own central axis, the cam follower 20 can achieve relative motion with respect to the transmission member 10, thereby converting the rotational motion of the cam body 200 into the linear motion of the transmission member 10.

[0125] Reference Figure 3 , Figure 4 and Figure 18 According to some embodiments of the present invention, the cam follower 20 includes a first mating part 211 and a second mating part 212. The first mating part 211 is mated with the guide groove 62. The transmission member 10 includes a connecting part 11. The connecting part 11 is provided with a mounting groove 111. The second mating part 212 is located in the mounting groove 111 and the second mating part 212 is movable relative to the mounting groove 111. The second mating part 212 is movable relative to the mounting groove 111, and the cam follower 20 can rotate around its own central axis relative to the transmission component 10. This allows the second mating part 212 to rotate within the mounting groove 111, and also allows the first mating part 211 to rotate within the guide groove 62. By allowing the first mating part 211 to rotate within the guide groove 62, the friction between the first mating part 211 and the inner wall of the guide groove 62 becomes rolling friction. This reduces frictional wear between the first mating part 211 and the inner wall of the guide groove 62, making the relative movement between the first mating part 211 and the cam body 200 smoother, and also helps to extend the service life of the cam follower 20 and the cam body 200.

[0126] For example, if the first mating part 211 does not rotate within the guide groove 62, when the first mating part 211 moves relative to the cam body 200, there is sliding friction between the first mating part 211 and the inner wall of the guide groove 62, resulting in severe frictional wear between the first mating part 211 and the inner wall of the guide groove 62. By rotating within the guide groove 62, at least a portion of the first mating part 211 rolls within the guide groove 62 when it moves relative to the cam body 200, resulting in rolling friction between the first mating part 211 and the inner wall of the guide groove 62. Compared to sliding friction, this reduces frictional wear between the first mating part 211 and the inner wall of the guide groove 62.

[0127] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, a bearing 50 is included. The bearing 50 is sleeved on the outer periphery of the second mating part 212 and the bearing 50 is located in the mounting groove 111. This can reduce or avoid frictional wear between the second mating part 212 and the inner wall of the mounting groove 111 due to direct contact, thereby helping to extend the service life of the cam follower 20 and the transmission component 10.

[0128] Reference Figure 4 , Figure 10 and Figure 11 According to some embodiments of the present invention, the bearing 50 is a rolling bearing 50, which includes an outer ring 51, an inner ring 52, and a rolling element 53. The rolling element 53 is located between the outer ring 51 and the inner ring 52. The outer ring 51 is fixed to the connecting part 11, and the inner ring 52 is sleeved on the outer periphery of the cam follower 20 and fixed relative to the cam follower 20. The outer ring 51 is fixed to the connecting part 11 of the transmission member 10. The outer ring 51 can support the rolling element 53 and the inner ring 52. By the rolling element 53 rolling between the inner ring 52 and the outer ring 51, the relative movement between the inner ring 52 and the outer ring 51 can be smoother. The relative movement between the inner ring 52 and the outer ring 51 can cause the cam follower 20 to move relative to the transmission member 10, thereby causing the first mating part 211 of the cam follower 20 to rotate in the guide groove 62 to convert the sliding friction between the first mating part 211 and the inner wall of the guide groove 62 into rolling friction.

[0129] Optionally, the cam follower 20 and the inner ring 52 can be an interference fit, which makes the connection between the cam follower 20 and the inner ring 52 simple and has strong stability.

[0130] Reference Figures 9-11 According to some embodiments of the present invention, the rolling element 53 is cylindrical or conical. The cylindrical or conical shape of the rolling element 53 can increase the bearing area of ​​the rolling element 53, thereby increasing the contact area between the rolling element 53 and the inner ring 52 and the outer ring 51. This can improve the power transmission efficiency between the inner ring 52 and the outer ring 51, and allow the rolling element 53 to bear a larger load, thereby effectively reducing the possibility of mechanical damage to the bearing 50 due to a large load.

[0131] For example, when bearing 50 is a ball bearing 50, the bearing area of ​​the balls is relatively small, and the bearing 50 is prone to mechanical damage under heavy load. By making the rolling element 53 cylindrical or conical, the bearing area of ​​the rolling element 53 can be larger, so that the rolling element 53 can withstand a larger load and reduce the mechanical damage of the bearing 50.

[0132] Reference Figure 4 , Figure 11 and Figure 12According to some embodiments of the present invention, the cam follower 20 includes a follower body 21 and a limiting protrusion 22. The follower body 21 includes a first mating portion 211 and a second mating portion 212. The limiting protrusion 22 is formed on the outer peripheral wall of the follower body 21 and extends circumferentially along the follower body 21. The limiting protrusion 22 is located between the first mating portion 211 and the second mating portion 212. In the axial direction of the bearing 50, the limiting protrusion 22 abuts against the inner ring 52 to limit the bearing 50. The abutting connection between the limiting protrusion 22 and the inner ring 52 makes the connection between the cam follower 20 and the inner ring 52 simple and has strong stability. Moreover, the abutting of the limiting protrusion 22 against the inner ring 52 can limit the bearing 50, which can reduce or avoid the possibility of the bearing 50 moving or loosening in the axial direction due to external impact or vibration.

[0133] Reference Figure 4 , Figure 7 and Figure 8 According to some embodiments of the present invention, the bottom wall of the mounting groove 111 includes a limiting wall 112, which abuts against the outer ring 51 to limit the bearing 50. The limiting wall 112 abuts against the outer ring 51, which can limit the bearing 50, so that the bearing 50 is accurately positioned on the transmission component 10, and can reduce or avoid the bearing 50 from moving or loosening in the axial direction due to external impact or vibration, thereby further improving the stability of the bearing 50 after assembly on the transmission component 10.

[0134] In addition, the limiting protrusion 22 abuts against the inner ring 52 to limit the inner ring 52, and the limiting wall 112 abuts against the outer ring 51 to limit the outer ring 51. In the axial direction of the bearing 50, the limiting protrusion 22 and the limiting wall 112 respectively play a limiting role at opposite ends of the bearing 50. In this way, the bearing 50 is doubly limited in the axial direction, which can further enhance the stability of the bearing 50 after it is assembled on the transmission component 10.

[0135] Reference Figure 4 and Figure 13 According to some embodiments of the present invention, at least a portion of the oil delivery channel 23 extends along the axial direction of the cam follower 20. This extension of at least a portion of the oil delivery channel 23 along the axial direction of the cam follower 20 may include, for example, a portion of the oil delivery channel 23 extending along the axial direction of the cam follower 20; or, for another example, the entire oil delivery channel 23 extending along the axial direction of the cam follower 20.

[0136] By extending at least a portion of the oil delivery channel 23 along the axial direction of the cam follower 20, the lubricating medium can be delivered from the receiving space 114 to the guide groove 62 via the oil delivery channel 23 to lubricate the relative movement between the cam follower 20 and the cam body 200.

[0137] Reference Figure 3 , Figure 4 and Figure 13 According to some embodiments of the present invention, the oil delivery channel 23 extends along the axial direction of the cam follower 20, and the central axis of the oil delivery channel 23 is collinear with the central axis of the cam follower 20. This allows the lubricating medium to flow along the central axis of the cam follower 20, reduces the flow resistance of the lubricating medium, and allows the lubricating medium to flow more smoothly into the guide groove 62 and to the mating point between the cam follower 20 and the cam body 200, thereby improving the lubrication effect.

[0138] Reference Figure 1 , Figure 3 , Figure 17 and Figure 18 According to some embodiments of the present invention, the transmission component 10 includes a transmission shaft 12 and a connecting portion 11. The connecting portion 11 is connected to one axial end of the transmission shaft 12. The cam follower 20 is connected to the connecting portion 11. The transmission shaft 12 is provided with a guide hole 121 extending along the movement direction of the transmission component 10. The cam body 200 is provided with a guide rod 63, which passes through the guide hole 121 and extends through the connecting portion 11 along the axial direction of the transmission shaft 12. The guide hole 121 facilitates the insertion of the guide rod 63, and through the cooperation between the guide rod 63 and the guide hole 121, it can guide and limit the movement direction of the transmission component 10, ensuring that the transmission component 10 moves along a set trajectory, such as the axial movement of the transmission component 10 along the transmission shaft 12. It can also limit the radial offset of the transmission component 10 along the transmission shaft 12, thus ensuring that the transmission component 10 moves along the axial direction of the transmission shaft 12.

[0139] For example, the cam body 200 rotates around its own central axis (for example, refer to...). Figure 17 When the central axis h) rotates, it can drive the cam follower 20, which is confined in the guide groove 62, to move relative to each other along the spiral. The end of the first mating part 211 of the cam follower 20 rolls back and forth against the inner wall of the guide groove 62. The second mating part 212 of the cam follower 20 is fixed to the transmission member 10 by the bearing 50. Since the cylindrical cam cannot move along the axial direction of the transmission shaft 12, the cam follower 20 moves along the axial direction of the transmission shaft 12. The cam follower 20 can drive the transmission member 10 to move along the axis of the transmission shaft 12 by moving along the axial direction of the transmission shaft 12. And through the cooperation between the guide hole 121 and the guide rod 63, the movement of the transmission member 10 in the radial direction of the transmission shaft 12 can be restricted to ensure that the transmission member 10 moves linearly along the axial direction of the transmission shaft 12.

[0140] In some embodiments, there are two cam followers 20 arranged opposite each other, and the connecting part 11 is provided with two opposite mounting grooves 111. The two cam followers 20 correspond to the two mounting grooves 111 respectively. The accommodating space 114 is located between the two mounting grooves 111. There are two oil storage components 30, and the two oil storage components 30 correspond to the two cam followers 20 respectively. The guide hole 121 is located between the two oil storage components 30. The guide rod 63 is permanently provided in the guide hole 121 and the guide rod 63 passes through the connecting part 11 along the axial direction of the transmission shaft 12. The space in the radial direction of the transmission component 10 can be fully utilized, so that the guide rod 63, the connecting part 11, the accommodating space 114 and the oil storage component 30 are arranged in an orderly manner, and the overall structure of the guide rod 63, the connecting part 11, the accommodating space 114 and the oil storage component 30 is compact.

[0141] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18 According to some embodiments of the present invention, the cam follower assembly 100 moves along the axial direction of the cam body 200. For example, the cam body 200 is rotatable, and the rotation of the cam body 200 can drive the cam follower assembly 100 to move. The cam follower assembly 100 can convert the rotation of the cam body 200 into axial movement along the cam body 200. The guide groove 62 can guide the movement of the cam follower assembly 100 to ensure that the cam follower assembly 100 moves along the axial direction of the cam body 200.

[0142] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18 According to a second aspect embodiment of the present invention, a cam follower assembly 100 includes a transmission member 10 and a cam follower 20. The transmission member 10 includes a connecting portion 11 and a cam follower 20. The cam follower 20 is connected to the connecting portion 11 to drive the transmission member 10 to move along the axial direction of the cam body 200. The cam follower 20 includes a first mating portion 211 and a second mating portion 212. The first mating portion 211 is used to engage with a guide groove 62 on the cam body 200, and the second mating portion 212 is movably connected to the connecting portion 11. Rotation of the cam body 200 can drive the cam follower 20 to move. The cam follower 20 can convert the rotational motion of the cam body 200 into linear motion of the transmission member 10, for example, linear motion of the transmission member 10 along its axial direction. This realizes the power transmission process between the cam body 200 and the transmission member 10.

[0143] The guide groove 62 facilitates the accommodation of the first mating part 211, enabling the transmission connection between the cam body 200 and the cam follower 20. The transmission component 10 provides fixation and support for the cam follower 20. The second mating part 212 is movably connected to the connecting part 11; for example, the second mating part 212 can rotate relative to the connecting part 11, allowing for rotational movement of the second mating part 212. This rotation also allows the first mating part 211 to rotate within the guide groove 62. This rotation of the first mating part 211 within the guide groove 62 reduces frictional wear between the first mating part 211 and the inner wall of the guide groove 62, resulting in smoother relative movement between the first mating part 211 and the cam body 200, and ultimately extending the service life of both the cam follower 20 and the cam body 200.

[0144] For example, if the first mating part 211 does not rotate within the guide groove 62, when the first mating part 211 moves relative to the cam body 200, there is sliding friction between the first mating part 211 and the inner wall of the guide groove 62, resulting in severe frictional wear between the first mating part 211 and the inner wall of the guide groove 62. By rotating within the guide groove 62, when the first mating part 211 moves relative to the cam body 200, at least a portion of the first mating part 211 rolls within the guide groove 62, resulting in rolling friction between the first mating part 211 and the inner wall of the guide groove 62. Compared to sliding friction, this reduces frictional wear between the first mating part 211 and the inner wall of the guide groove 62.

[0145] The rolling of at least a portion of the first mating part 211 within the guide groove 62 may include the following situations: for example, a portion of the first mating part 211 may roll within the guide groove 62; or, for another example, the entire first mating part 211 may roll within the guide groove 62.

[0146] According to an embodiment of the present invention, the cam follower assembly 100 is movably connected to the connecting portion 11 via a second mating portion 212. The second mating portion 212 is movable relative to the connecting portion 11, for example, the second mating portion 212 can rotate relative to the connecting portion 11. Correspondingly, the first mating portion 211 can also rotate within the guide groove 62 of the cam body 200. Because the first mating portion 211 can rotate within the guide groove 62, when the first mating portion 211 moves relative to the cam body 200, the friction between the first mating portion 211 and the inner wall of the guide groove 62 can be made into rolling friction, which can reduce the frictional wear between the first mating portion 211 and the inner wall of the guide groove 62, making the relative movement between the first mating portion 211 and the cam body 200 smoother, and extending the overall service life of the cam follower assembly 100.

[0147] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18 According to some embodiments of the present invention, the cam follower 20 can rotate about its own central axis relative to the connecting part 11, which can realize the rotational movement of the second mating part 212 relative to the connecting part 11, and can also realize the rotational movement of the first mating part 211 within the guide groove 62. By making the first mating part 211 rotatable within the guide groove 62, the friction between the first mating part 211 and the inner wall of the guide groove 62 is rolling friction, thereby reducing the frictional wear between the first mating part 211 and the inner wall of the guide groove 62, and thus extending the service life of the cam follower 20 and the cam body 200.

[0148] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18 According to some embodiments of the present invention, the connecting portion 11 is provided with a mounting groove 111, and the second mating portion 212 is located within the mounting groove 111 and is movable relative to the mounting groove 111. The mounting groove 111 facilitates the accommodation of the second mating portion 212, making the assembly between the cam follower 20 and the transmission component 10 more convenient, and making the overall structure of the cam follower 20 and the transmission component 10 more compact. Because the second mating portion 212 is movable relative to the mounting groove 111, for example, when the cam follower 20 rotates relative to the connecting portion 11 around its own central axis, the first mating portion 211 can rotate within the guide groove 62 and the second mating portion 212 can rotate within the mounting groove 111. By allowing the second mating portion to rotate within the mounting groove 111, the cam follower 20 can be prevented from jamming, ensuring that the first mating portion 211 can rotate within the guide groove 62, thereby reducing frictional wear between the first mating portion 211 and the inner wall of the guide groove 62.

[0149] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, a bearing 50 is included. The bearing 50 is sleeved on the outer periphery of the second mating part 212 and the bearing 50 is located in the mounting groove 111. This can reduce or avoid frictional wear between the second mating part 212 and the inner wall of the mounting groove 111 due to direct contact, thereby helping to extend the service life of the cam follower 20 and the transmission component 10.

[0150] Reference Figure 4 , Figure 10 and Figure 11According to some embodiments of the present invention, the bearing 50 is a rolling bearing 50, which includes an outer ring 51, an inner ring 52, and rolling elements 53.

The outer ring 51 is fixed to the transmission member 10, and the inner ring 52 is sleeved on the outer periphery of the cam follower 20 and fixed relative to the cam follower 20. The outer ring 51 is fixed to the transmission member 10 and can support the rolling elements 53 and the inner ring 52. By the rolling elements 53 rolling between the inner ring 52 and the outer ring 51, the relative movement between the inner ring 52 and the outer ring 51 can be smoother. The relative movement between the inner ring 52 and the outer ring 51 can cause the cam follower 20 to move relative to the transmission member 10, thereby causing the first mating part 211 of the cam follower 20 to rotate in the guide groove 62, so as to convert the sliding friction between the first mating part 211 and the inner wall of the guide groove 62 into rolling friction.

[0151] Optionally, the cam follower 20 and the inner ring 52 can be an interference fit, which makes the connection between the cam follower 20 and the inner ring 52 simple and has strong stability.

[0152] Reference Figures 9-11 According to some embodiments of the present invention, the rolling element 53 is cylindrical or conical. The cylindrical or conical shape of the rolling element 53 can increase the bearing area of ​​the rolling element 53, thereby increasing the contact area between the rolling element 53 and the inner ring 52 and the outer ring 51. This can improve the power transmission efficiency between the inner ring 52 and the outer ring 51, and allow the rolling element 53 to bear a larger load, thereby effectively reducing the possibility of mechanical damage to the bearing 50 due to a large load.

The follower body 21 includes a first mating portion 211 and a second mating portion 212. The limiting protrusion 22 is formed on the outer peripheral wall of the follower body 21 and extends circumferentially along the follower body 21. The limiting protrusion 22 is located between the first mating portion 211 and the second mating portion 212. In the axial direction of the bearing 50, the limiting protrusion 22 abuts against the inner ring 52 to limit the bearing 50. The abutting connection between the limiting protrusion 22 and the inner ring 52 makes the connection between the cam follower 20 and the inner ring 52 simple and has strong stability. Moreover, the abutting of the limiting protrusion 22 against the inner ring 52 can limit the bearing 50, which can reduce or avoid the possibility of the bearing 50 moving or loosening in the axial direction due to external impact or vibration.

The limiting wall 112 abuts against the outer ring 51, which can limit the bearing 50, so that the bearing 50 is accurately positioned on the transmission component 10, and can reduce or avoid the bearing 50 from moving or loosening in the axial direction due to external impact or vibration, thereby further improving the stability of the bearing 50 after assembly on the transmission component 10.

[0155] In addition, the limiting protrusion 22 abuts against the inner ring 52 to limit the inner ring 52, and the limiting wall 112 abuts against the outer ring 51 to limit the outer ring 51. In the axial direction of the bearing 50, the limiting protrusion 22 and the limiting wall 112 respectively play a limiting role at opposite ends of the bearing 50. In this way, the bearing 50 is doubly limited in the axial direction, which can further enhance the stability of the bearing 50 after it is assembled on the transmission component 10.

[0156] Reference Figure 1 , Figure 2 and Figure 5 According to some embodiments of the present invention, there are two cam followers 20 arranged opposite each other, and both cam followers 20 are movably connected to the connecting part 11. By having two cam followers 20 arranged opposite each other, for example, the connecting part 11 is provided with two oppositely arranged mounting grooves 111, and the two cam followers 20 correspond to the two oppositely arranged mounting grooves 111 respectively, the contact stress between the cam followers 20 and the cam can be dispersed, thereby reducing the wear on individual cam followers 20 and helping to extend the service life of the cam followers 20.

[0157] In some embodiments, there are two cam followers 20 arranged opposite each other. Guide grooves 62 are formed on the inner peripheral wall of the cam and are arranged opposite each other. The two guide grooves 62 respectively cooperate with the cam followers 20. The extension trajectory of the guide grooves 62 is a spiral. By having two guide grooves 62 arranged opposite each other and cooperating with two cam followers 20 respectively, the cam followers 20 can be driven to move along the extension trajectory of the guide grooves 62 better, and the contact stress between the cam followers 20 and the cam can be better dispersed.

[0158] Reference Figure 3 , Figure 4 , Figure 17 and Figure 18According to a third aspect embodiment of the present invention, a cam follower assembly includes a cam follower 20 and a lubrication mechanism. The cam follower 20 includes a first mating portion 211 and a second mating portion 212. The first mating portion 211 is used to mate with a guide groove 62 on a cam body 200, and the second mating portion 212 is used to connect with a transmission member 10 to drive the transmission member 10 to move along the axial direction of the cam body 200. The lubrication mechanism is disposed on the cam follower 20 and is used to lubricate the mating point between the cam body 200 and the cam follower 20. The rotation of the cam body 200 can drive the cam follower 20 to move. The cam follower 20 can convert the rotation of the cam body 200 into axial movement along the cam body 200. Through the first mating part 211 and the guide groove 62, the rotation of the cam body 200 can drive the first mating part 211 to move. The movement of the first mating part 211 can drive the movement of the second mating part 212. The second mating part 212 is connected to the transmission member 10 through the second mating part 212. The movement of the second mating part 212 can drive the transmission member 10 to move, thereby realizing the power transmission process between the cam body 200 and the transmission member 10.

[0159] The guide groove 62 can guide the movement of the first mating part 211 so that the first mating part 211 moves along a predetermined trajectory and a predetermined line of defense, thereby ensuring that the cam follower 20 moves along the axial direction of the cam body 200.

[0160] When the cam follower 20 moves relative to the cam body 200, there is friction between the first mating part 211 and the inner wall of the guide groove 62. The lubrication mechanism is used to lubricate the mating part between the cam body 200 and the cam follower 20. This provides lubrication for the mating between the cam follower 20 and the cam body 200, making the relative movement between the cam follower 20 and the cam body 200 smoother and reducing friction and wear between the cam follower 20 and the cam body 200.

[0161] According to an embodiment of the present invention, the cam follower assembly has a lubrication mechanism on the cam follower 20, which is used to lubricate the mating part between the cam body 200 and the cam follower 20. When the cam follower 20 and the cam body 200 move relative to each other, the lubrication mechanism can provide lubrication to the mating part between the first mating part 211 and the guide groove 62, so that the relative movement between the first mating part 211 and the guide groove 62 is smoother and the friction and wear between the first mating part 211 and the guide groove 62 can be reduced, thereby helping to extend the overall service life of the cam follower assembly.

[0162] Reference Figure 3 , Figure 4 and Figure 13According to some embodiments of the present invention, the lubrication mechanism includes an oil reservoir 30 and an oil delivery channel 23. The oil reservoir 30 is connected to a cam follower 20, and the cam follower 20 forms an oil delivery channel 23. The oil reservoir 30 delivers lubricating medium to the mating point between the cam body 200 and the cam follower 20 through the oil delivery channel 23. The oil reservoir 30 can store lubricating medium to ensure a long-term supply of lubricating medium. The oil delivery channel 23 can deliver lubricating medium from the oil reservoir 30 to the mating point between the cam body 200 and the cam follower 20. When the cam follower assembly 100 and the cam body 200 move relative to each other, the lubricating medium can provide lubrication between the cam follower 20 and the inner wall of the guide groove 62, so that the relative movement between the cam follower 20 and the cam body 200 is smoother and the frictional wear between the cam follower 20 and the cam body 200 can be reduced.

[0163] Reference Figure 3 , Figure 4 and Figure 16 According to some embodiments of the present invention, the oil reservoir 30 is provided with a connecting joint 40, an oil delivery channel 23 is formed in the first mating part 211, and a mounting hole 24 is provided in the second mating part 212. The connecting joint 40 is accommodated in the mounting hole 24, and a flow channel 44 is formed in the connecting joint 40, which connects the storage cavity 31 of the oil reservoir 30 and the oil delivery channel 23. The mounting hole 24 facilitates the accommodation of the connecting joint 40, and the mounting hole 24 is located on the side of the oil delivery channel 23 adjacent to the accommodating space 114, which makes the distance between the mounting hole 24 and the connecting joint 40 closer, making the assembly between the oil reservoir 30 and the cam follower 20 more convenient, and making the overall structure of the oil reservoir 30 and the cam follower 20 more compact. The flow channel 44 connects the storage cavity 31 and the oil delivery channel 23, which facilitates the flow of the lubricating medium in the storage cavity 31 to the oil delivery channel 23 via the flow channel 44.

[0164] Reference Figures 15-16 According to some embodiments of the present invention, the flow channel 44 is formed as a Tesla valve structure. Due to the unidirectional flow of the Tesla valve structure, the flow path of the lubricating medium in the storage cavity 31 through the flow channel 44 toward the oil delivery channel 23 is unidirectional, which can reduce or avoid the possibility of the lubricating medium flowing back into the storage cavity 31, thereby improving the lubrication effect on the cam follower assembly 100.

[0165] Reference Figure 3 , Figure 4 and Figure 16 According to some embodiments of the present invention, the connecting joint 40 is threadedly connected to the mounting hole 24, which makes the connection between the oil reservoir 30 and the cam follower 20 simple and has strong stability.

[0166] Reference Figure 3 , Figure 4 and Figure 14 According to some embodiments of the present invention, the mounting hole 24 includes a first hole segment 241 and a second hole segment 242 arranged along the axial direction of the mounting hole 24. A first limiting step surface 243 is formed between the first hole segment 241 and the second hole segment 242. The connecting joint 40 includes a first connecting segment 41 and a second connecting segment 42 arranged along the axial direction of the connecting joint 40. A second limiting step surface 43 is formed between the first connecting segment 41 and the second connecting segment 42. The first connecting segment 41 is accommodated in the first hole segment 241. The second limiting step surface 43 is located in the first hole segment 241 and abuts against the first limiting step surface 243 in the axial direction of the mounting hole 24. The second connecting segment 42 is accommodated in the second hole segment 242. The first connecting section 41 is accommodated in the first hole section 241 and the second connecting section 42 is accommodated in the second hole section 242, which facilitates the installation of the connecting joint 40 at the mounting hole 24, thereby making the assembly between the cam follower 20 and the oil reservoir 30 more convenient and allowing for a more compact overall structure of the cam follower 20 and the oil reservoir 30. The abutment between the second limiting step surface 43 and the first limiting step surface 243 in the axial direction of the mounting hole 24 ensures accurate assembly positioning between the cam follower 20 and the oil reservoir 30.

[0167] Reference Figure 4 , Figure 13 and Figure 16 According to some embodiments of the present invention, the second connecting segment 42 is threadedly connected to the second hole segment 242, which makes the connection between the second connecting segment 42 and the second hole segment 242 simple and has strong stability.

[0168] Reference Figure 1 , Figure 3 and Figure 16 According to some embodiments of the present invention, the oil reservoir 30 can move together with the cam follower 20. The lubricating medium inside the oil reservoir 30 will flow out from the oil reservoir 30 and flow to the oil delivery channel 23 due to its own rotation. The automatic oil discharge function of the oil reservoir 30 is realized by utilizing the rotation of the oil reservoir 30. This can simplify the structure of the oil reservoir 30 and save manufacturing costs compared to the automatic oil discharge function of the oil reservoir 30 controlled by an electronic control module.
