Description

Technical Field

[0001] This invention relates to the field of clutch technology, and more particularly to one-way clutches. Background Technology

[0002] One-way clutch bearings are a type of bearing characterized by their ability to rotate in one direction and stop in the opposite direction. Therefore, one-way clutches are widely used in the machinery industry. Currently, existing one-way clutches mainly include roller-type one-way clutches and wedge-type one-way clutches. Regarding roller-type one-way clutches, one existing technology mainly includes an inner ring, an outer ring, and rolling support components and elastic elements disposed between the inner and outer rings. However, this type of one-way clutch has a large number of parts, a complex assembly process, and is prone to errors. Furthermore, when assembling the rolling support components and elastic elements between the inner and outer rings, parts are prone to detachment, resulting in low assembly efficiency and, in severe cases, affecting the subsequent performance. Summary of the Invention

[0003] The purpose of this invention is to provide a one-way clutch to solve the problems of existing one-way clutches having a large number of parts, and the rolling support components and springs being prone to falling off during assembly, resulting in low assembly efficiency and poor performance.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A one-way clutch, mounted on a drive shaft, includes an outer ring and a plurality of first elastic rolling support assemblies. The plurality of first elastic rolling support assemblies are spaced apart circumferentially along the outer ring. The inner wall of the outer ring is provided with a plurality of first limiting members spaced apart circumferentially. The plurality of first elastic rolling support assemblies and the plurality of first limiting members are arranged in a one-to-one correspondence. The first elastic rolling support assembly includes:

[0006] A first elastic element, one end of which is connected to the outer ring;

[0007] A first roller is rotatably connected to the other end of the first elastic member. The first roller is partially located within the first limiting member, and its outer circumferential surface contacts the outer circumferential surface of the drive shaft. The drive shaft can drive the first roller to rotate in a first clockwise direction to reach a first working position. The drive shaft can also drive the first roller to rotate in a second clockwise direction to reach a second working position. When the first roller is in the first working position, it abuts against the drive shaft and the first limiting member along the radial direction of the outer ring. When the first roller is in the second working position, it rotates with the drive shaft, and the elastic restoring force of the first elastic member can move the first roller from the first working position to the second working position. The first clockwise direction and the second clockwise direction are opposite.

[0008] Preferably, the first limiting member is a wedge-shaped groove, and the first roller portion is located in the wedge-shaped groove. When the first roller is in the first working position, the first roller abuts against the drive shaft and the inner wall of the wedge-shaped groove along the radial direction of the outer ring (1).

[0009] Preferably, the first elastic element includes a first part, a second part, and a third part. The first part connects the second part and the third part. Both the second part and the third part extend along the first clockwise direction and are radially spaced along the outer ring. The first part and the second part are used to connect with the outer ring, and the first roller is rotatably connected to the third part.

[0010] Preferably, the outer ring is provided with a first groove extending radially, and the first portion is inserted into the first groove;

[0011] The second part consists of two parts. Both ends of the outer ring along the axial direction are provided with a second groove that communicates with the first groove. The two second parts and the two second grooves are arranged in a one-to-one correspondence. The second part is inserted into the second groove.

[0012] Preferably, the first part includes a first connecting plate, and a second connecting plate and a third connecting plate connected to the first connecting plate. The second connecting plate and the third connecting plate are disposed opposite to each other and spaced apart at both ends of the first connecting plate. The second connecting plate is connected to the second part, and the third connecting plate is connected to the third part.

[0013] Along the depth direction of the first groove, the width of the second connecting plate is D1, and the length of the third connecting plate is D2, where D2 > the depth of the first groove > D1.

[0014] Preferably, the angle between the second connecting plate and the second part is less than or equal to 90°; the angle between the third connecting plate and the third part is less than or equal to 90°.

[0015] Preferably, the first elastic rolling support assembly further includes a fixed shaft, the third part is provided with two connecting ears at intervals, the fixed shaft is inserted into the two connecting ears and fixedly connected to the two connecting ears, and the first roller is rotatably disposed on the fixed shaft and located between the two connecting ears.

[0016] Preferably, the outer ring, the first elastic element, and the first roller are all made of metal.

[0017] Preferably, the one-way clutch further includes a plurality of second elastic rolling support assemblies, and the inner wall of the outer ring is provided with a plurality of second limiting members spaced apart circumferentially, the plurality of second limiting members being configured one-to-one with the plurality of second elastic rolling support assemblies, the second elastic rolling support assembly comprising:

[0018] A second elastic element, one end of which is connected to the outer ring;

[0019] The second roller is rotatably connected to the other end of the second elastic member. The second roller rolls within the second limiting member and makes rolling contact with the drive shaft.

[0020] Preferably, the second limiting member is a U-shaped third groove, and the second roller rolls within the third groove;

[0021] Along the circumference of the outer ring, the bottom wall width of the third groove is greater than or equal to the width of the wedge-shaped groove.

[0022] The beneficial effects of this invention are:

[0023] The present invention aims to provide a one-way clutch, comprising an outer ring and a plurality of first elastic rolling support assemblies, the plurality of first elastic rolling support assemblies being spaced apart circumferentially along the outer ring, and a plurality of first limiting members being spaced apart circumferentially along the inner wall of the outer ring, the plurality of first elastic rolling support assemblies and the plurality of first limiting members being arranged in a one-to-one correspondence, the plurality of first elastic rolling support assemblies comprising a first elastic element and a first roller, one end of the first elastic element being connected to the outer ring; the first roller being rotatably connected to the other end of the first elastic element, the first roller portion being located within the first limiting member, and the outer peripheral surface of the first roller being flush with the drive shaft. The outer peripheral surface contacts the first roller, and the drive shaft can drive the first roller to rotate in a first clockwise direction so that the first roller reaches the first working position. The drive shaft can also drive the first roller to rotate in a second clockwise direction so that the first roller reaches the second working position. When the first roller is in the first working position, the first roller abuts against the drive shaft and the first limiting member along the radial direction of the outer ring. When the first roller is in the second working position, the first roller rotates with the drive shaft, and the elastic restoring force of the first elastic member can drive the first roller to move from the first working position to the second working position. The first clockwise direction and the second clockwise direction are opposite.

[0024] In this one-way clutch, the outer circumferential surface of the drive shaft directly contacts the outer circumferential surface of the first roller. When the drive shaft moves in a first clockwise direction, it drives the first roller to move in a first clockwise direction within the first limiting member until the first roller abuts against the drive shaft and the first limiting member along the radial direction of its outer ring. At this point, the drive shaft can no longer rotate in a first clockwise direction, and the first roller can no longer move in a first clockwise direction. The relative position of the first roller and the drive shaft is locked, causing the first roller to reach the first working position. It is understood that during this process, the first elastic member undergoes elastic deformation. When the drive shaft moves in a second clockwise direction, it drives the first roller to move in a second clockwise direction within the first limiting member, causing the first roller to leave the position abutting against the drive shaft and the first limiting member. At this point, the first roller rotates in coordination with the drive shaft, allowing the drive shaft to rotate normally in a second clockwise direction. At this point, the first roller reaches the second working position. It is understood that during this process, the elastic restoring force of the first elastic member can drive the first roller to quickly return from the first working position to the second working position. Therefore, this one-way clutch can drive the drive shaft to rotate only in the second clockwise direction, realizing the one-way rotation of the drive shaft. Compared with the prior art, this one-way clutch does not need to set an inner ring. One end of the first elastic element is connected to the outer ring, and the other end is rotatably connected to the first roller. Therefore, the first elastic rolling support assembly can be directly assembled onto the outer ring as a whole, effectively reducing the number of parts. It has a simple structure, is easy to operate, has high assembly efficiency, can also prevent the first roller from falling off, and has good performance. Attached Figure Description

[0035] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] For roller-type one-way clutches, one type of existing one-way clutch mainly includes an inner ring, an outer ring, and a rolling support assembly and an elastic element disposed between the inner ring and the outer ring. However, this type of one-way clutch has a large number of parts, the assembly process is complex and prone to errors, and the parts are prone to falling off when assembling the rolling support assembly and the elastic element between the inner ring and the outer ring, resulting in low assembly efficiency and, in severe cases, affecting the later use effect.

[0039] This invention provides a one-way clutch, such as Figure 1-5As shown, an outer ring 1 and multiple first elastic rolling support assemblies 2 are arranged at intervals along the circumference of the outer ring 1. Multiple first limiting members 11 are arranged at intervals along the circumference of the inner wall of the outer ring 1. Each first elastic rolling support assembly 2 and each first limiting member 11 is arranged in a one-to-one correspondence. Each first elastic rolling support assembly 2 includes a first elastic element 21 and a first roller 22. One end of the first elastic element 21 is connected to the outer ring 1; the first roller 22 is rotatably connected to the other end of the first elastic element 21. A portion of the first roller 22 is located within the first limiting member 11, and the outer circumferential surface of the first roller 22 contacts the outer circumferential surface of the drive shaft, thus driving the transmission... The shaft can drive the first roller 22 to rotate in a first clockwise direction so that the first roller 22 reaches the first working position. The drive shaft can also drive the first roller 22 to rotate in a second clockwise direction so that the first roller 22 reaches the second working position. When the first roller 22 is in the first working position, the first roller 22 abuts against the drive shaft and the first limiting member 11 along the radial direction of the outer ring 1. When the first roller 22 is in the second working position, the first roller 22 rotates with the drive shaft. The elastic restoring force of the first elastic member 21 can drive the first roller 22 to move from the first working position to the second working position. The first clockwise direction and the second clockwise direction are opposite.

[0040] This one-way clutch, such as Figure 1-5As shown, the outer circumferential surface of the drive shaft is in direct contact with the outer circumferential surface of the first roller 22. When the drive shaft moves in a clockwise direction, it drives the first roller 22 to move in a clockwise direction within the first limiting member 11 until the first roller 22 abuts against the drive shaft and the first limiting member 11 along the radial direction of the outer ring 1. At this point, the drive shaft can no longer rotate in a clockwise direction, and the first roller 22 can no longer move in a clockwise direction. The relative position of the first roller 22 and the drive shaft is locked, causing the first roller 22 to reach the first working position. It can be understood that during this process, the first spring... The elastic component 21 undergoes elastic deformation. When the drive shaft moves in a second clockwise direction, it drives the first roller 22 to move in the second clockwise direction within the first limiting component 11, causing the first roller 22 to leave the position where it is pressed against the drive shaft and the first limiting component 11. At this time, the first roller 22 rotates with the drive shaft, allowing the drive shaft to rotate normally in the second clockwise direction. At this time, the first roller 22 reaches the second working position. It can be understood that during this process, the elastic restoring force of the first elastic component 21 can drive the first roller 22 to quickly return from the first working position to the second working position. Thus, the one-way clutch can drive the drive shaft to rotate only in the second clockwise direction, realizing the one-way rotation of the drive shaft. Moreover, compared with the prior art, the one-way clutch does not need to set an inner ring. One end of the first elastic component 21 is connected to the outer ring 1, and the other end is rotatably connected to the first roller 22. Therefore, the first elastic rolling support assembly 2 can be directly assembled onto the outer ring 1 as a whole, effectively reducing the number of parts. It has a simple structure, is easy to operate, has high assembly efficiency, and can also prevent the first roller 22 from falling off, resulting in good performance.

[0041] in, Figure 1 In the diagram, the ab direction is the first clockwise direction, and the cd direction is the second clockwise direction. The first and second clockwise directions are opposite in direction.

[0042] Among them, such as Figure 1-5As shown, the first limiting member 11 is a wedge-shaped groove, and the first roller 22 is partially located within the wedge-shaped groove. When the first roller 22 is in the first working position, it abuts against the drive shaft and the inner wall of the wedge-shaped groove along the radial direction of the outer ring 1. By setting the first limiting member 11 as a wedge-shaped groove, the first roller 22 can abut against the drive shaft and the inner wall of the wedge-shaped groove along the radial direction of the outer ring 1 during its movement in the first clockwise direction, and can rotate with the drive shaft during its movement in the second clockwise direction. Understandably, when the first roller 22 is in the first working position, the first roller 22 abuts against the narrower end of the wedge groove, so that the first roller 22 can no longer move around the first clockwise direction, thus preventing the drive shaft from rotating around the first clockwise direction. When the first roller 22 moves around the first clockwise direction, the first roller 22 moves from the narrower end to the wider end of the wedge groove, allowing the first roller 22 to re-engage with the drive shaft, thereby enabling the drive shaft to rotate only around the second clockwise direction, achieving unidirectional rotation of the drive shaft.

[0043] Among them, such as Figure 1 , Figure 4 and Figure 5 As shown, the first elastic element 21 includes a first part 211, a second part 212, and a third part 213. The first part 211 connects the second part 212 and the third part 213. Both the second part 212 and the third part 213 extend in a first clockwise direction and are radially spaced along the outer ring 1. The first part 211 and the second part 212 are used to connect with the outer ring 1, and the first roller 22 is rotatably connected to the third part 213. This arrangement allows one end of the first elastic element 21 to be connected to the outer ring 1 radially, and the other end to be rotatably connected to the first roller 22. When the drive shaft drives the first roller 22 to move in a first clockwise direction, it can prevent the first elastic element 21 from detaching from the outer ring 1 and ensure that the connection between the second part 212 and the third part 213 of the first elastic element 21 can effectively undergo elastic deformation.

[0044] Specifically, such as Figure 1-5 As shown, the outer ring 1 has a first groove 12 extending radially, and a first part 211 is inserted into the first groove 12; there are two second parts 212, and each end of the outer ring 1 along the axial direction has a second groove 13 communicating with the first groove 12. The two second parts 212 and the two second grooves 13 are arranged in a one-to-one correspondence, and the second part 212 is inserted into the second groove 13. This arrangement is to connect the outer ring 1 and the first elastic member 21 through the first part 211 and the second part 212, preventing the first elastic member 21 from detaching from the outer ring 1, and ensuring that the connection between the second part 212 and the third part 213 of the first elastic member 21 can effectively undergo elastic deformation.

[0045] More specifically, such as Figure 1-5 As shown, the first part 211 includes a first connecting plate 2111, and a second connecting plate 2112 and a third connecting plate 2113 connected to the first connecting plate 2111. The second connecting plate 2112 and the third connecting plate 2113 are disposed opposite to and spaced apart at both ends of the first connecting plate 2111. The second connecting plate 2112 is connected to the second part 212, and the third connecting plate 2113 is connected to the third part 213. Along the depth direction of the first groove 12, the width of the second connecting plate 2112 is D1, and the length of the third connecting plate 2113 is D2, where D2 > depth of the first groove 12 > D1. It is understood that the first part 211 is a roughly rectangular plate, and the first groove 12 is roughly rectangular. The shape of the first part 211 matches the shape of the first groove 12. The first connecting plate 2111, the second connecting plate 2112, and the third connecting plate 2113 respectively fit against the three inner sidewalls of the first groove 12. The first part 211 and the first groove 12 have an overfit or an interference fit. The depth of the first groove 12 is set to D2 > D1, so that the second connecting plate 2112 is completely contained within the first groove 12. When the drive shaft drives the first roller 22 to move in the first clockwise direction or the second clockwise direction, the first elastic member 21 will not disengage from the first groove 12. Furthermore, the two second parts 212 are respectively inserted into the two second grooves 13, further preventing the first elastic member 21 from disengaging from the outer ring 1, thus ensuring the reliability of the one-way clutch.

[0046] More specifically, such as Figure 3-5 As shown, the first groove 12 is provided with a limiting surface 121, and the second connecting plate 2112 of the first part 211 abuts against the limiting surface 121 radially along the outer ring 1. This arrangement can further prevent the first elastic element 21 from disengaging from the outer ring 1, and further ensure the reliability of the one-way clutch.

[0047] The included angle between the second connecting plate 2112 and the second part 212 is less than or equal to 90°. This arrangement increases the reliability of the connection between the second part 212 and the outer ring 1.

[0048] The included angle between the third connecting plate 2113 and the third part 213 is less than or equal to 90°. Understandably, this angle of less than or equal to 90° when not in operation allows the first roller 22 to effectively deform at the connection between the third connecting plate 2113 and the third part 213 when the drive shaft drives the first roller 22 to move in a first clockwise direction. This increases the included angle between the third connecting plate 2113 and the third part 213 until the first roller 22 abuts against the drive shaft and the first limiting member 11 radially along the outer ring 1. When the drive shaft drives the first roller 22 to move in a second clockwise direction, the elastic restoring force of the first elastic member 21 causes the connection between the third connecting plate 2113 and the third part 213 to deform until it returns to its initial state. At this point, the first roller 22 and the drive shaft rotate and engage again.

[0049] Among them, such as Figure 1 , Figure 4 and Figure 5 As shown, the first elastic rolling support assembly 2 also includes a fixed shaft 23. The third part 213 is provided with two connecting ears 2131 spaced apart. The fixed shaft 23 is inserted into and fixedly connected to the two connecting ears 2131. The first roller 22 is rotatably disposed on the fixed shaft 23 and located between the two connecting ears 2131. This arrangement enables the first roller 22 to be rotatably connected to the third part 213. In this embodiment, the fixed shaft 23 is interference-fitted into the two connecting ears 2131. As an alternative, the fixed shaft 23 can also be welded to the two connecting ears 2131 after being inserted into them. The goal is to enable the fixed shaft 23 to be actively connected to the third part 213.

[0050] In this embodiment, the outer ring 1, the first elastic element 21, and the first roller 22 are all made of metal. This improves the performance and reliability of the one-way clutch. The metal material has good strength and hardness, enabling the first roller 22 to withstand radial loads.

[0051] In this embodiment, the first part 211, the two second parts 212, and the third part 213 of the first elastic element 21 are integrally formed. This configuration can save processing costs, reduce assembly steps, and at the same time ensure the structural strength of the first elastic element 21, thereby improving the reliability of the first elastic element 21 and further improving the reliability of the one-way clutch.

[0052] Among them, such as Figure 1 and Figure 2As shown, the outer circumferential surface of the outer ring 1 is provided with multiple protrusions 14 at intervals, and the distance between any two adjacent protrusions 14 is L, and any two L are not equal. By providing multiple protrusions 14 along the circumferential direction on the outer circumferential surface of the outer ring 1, and the distance between any two adjacent protrusions 14 is L, and any two L are not equal, the incorrect assembly direction of the outer ring 1 of the one-way clutch when it is assembled into the reducer is prevented; at the same time, the protrusions 14 can ensure that the circumferential position of the one-way clutch does not change after it is assembled into the reducer.

[0053] Among them, such as Figure 1 , Figure 2 and Figure 6 As shown, the one-way clutch also includes multiple second elastic rolling support assemblies 3. Multiple second limiting members 15 are spaced circumferentially along the inner wall of the outer ring 1, with each second limiting member 15 corresponding to one of the multiple second elastic rolling support assemblies 3. Each second elastic rolling support assembly 3 includes a second elastic member 31 and a second roller 32. One end of the second elastic member 31 is connected to the outer ring 1; the second roller 32 is rotatably connected to the other end of the second elastic member 31. The second roller 32 rolls within the second limiting member 15 and rolls in contact with the drive shaft. By setting the second roller 32 to roll within the second limiting member 15 and roll in contact with the drive shaft, it can be understood that the second roller 321, the second limiting member 15, and the drive shaft are all in contact, allowing the second roller 32 to support the rotation of the drive shaft and ensure that the rotation centerline of the drive shaft coincides with its central axis. This ensures that the first elastic rolling support assembly 2 can limit the drive shaft to rotate only in one direction, effectively improving the performance of the one-way clutch.

[0054] Specifically, in this embodiment, the structure of the second elastic element 31 is the same as that of the first elastic element 21; the structure of the second roller 32 is the same as that of the first roller 22; the connection method between the second elastic element 31 and the second roller 32 is the same as the connection method between the first elastic element 21 and the first roller 22; and the connection method between the second elastic element 31 and the outer ring 1 is the same as the connection method between the first elastic element 21 and the outer ring 1. This arrangement reduces the number of parts and facilitates assembly, disassembly, and subsequent maintenance.

[0055] Specifically, in this embodiment, both the second elastic element 31 and the second roller 32 are made of metal. This further improves the performance and reliability of the one-way clutch. The metal material has good strength and hardness, enabling the second roller 32 to withstand radial loads.

[0056] Specifically, such as Figure 1 , Figure 2 and Figure 6As shown, the second limiting member 15 is an arc-shaped third groove, and the second roller 32 rolls within the third groove. Along the circumference of the outer ring 1, the width of the bottom wall of the third groove is greater than or equal to the width of the wedge-shaped groove. Specifically, the inner wall of the third groove includes a bottom wall and two side walls connected to both ends of the bottom wall along the circumference of the outer ring 1. Therefore, the width of the bottom wall of the third groove is set to be greater than the width of the wedge-shaped groove, so that when the drive shaft drives the first roller 22 to move in the first limiting member 11 in a clockwise direction, and the first roller 22 abuts against the drive shaft and the first limiting member 11, the second roller 32 can still contact the bottom wall of the third groove. This ensures that the second roller 32 can always support the drive shaft, guaranteeing that the rotation center line of the drive shaft coincides with the central axis of the drive shaft.

[0057] Specifically, in this embodiment, such as Figure 1 As shown, along the circumference of the outer ring 1, a second elastic rolling support assembly 3 is arranged between every four first elastic rolling support assemblies 2. Furthermore, along the circumference of the outer ring 1, the spacing between any two adjacent first elastic rolling support assemblies 2 is the same; the spacing between adjacent first elastic rolling support assemblies 2 and second elastic rolling support assemblies 3 is the same as the spacing between two adjacent first elastic rolling support assemblies 2. This arrangement ensures that the drive shaft assembled in the one-way clutch experiences uniform force along the circumference, thereby further improving the performance of the one-way clutch. It is understood that, along the circumference of the outer ring 1, a second elastic rolling support assembly 3 can be arranged between every plurality of first elastic rolling support assemblies 2, depending on requirements; the plurality of first elastic rolling support assemblies 2 can be two, three, four, or five, etc.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
