Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and specifically relates to a disassembly and assembly tool for a bearing outer ring. Background Technique

[0002] A rolling bearing is a precision mechanical component that changes the sliding friction between a rotating shaft and a shaft seat into rolling friction, thereby reducing friction loss. A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, and their shape, size, and quantity directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements, guide the rolling elements to rotate, and play a lubricating role.

[0003] For example, the application number is: CN202220940937.7. The utility model relates to a rolling bearing outer ring disassembly device, including a bearing seat, in which a bearing outer ring is clamped. An outer ring disassembly component is arranged on the bearing seat and the bearing outer ring. The outer ring disassembly component includes an adjusting screw rod, on which a fixed frame is threadedly arranged. A fixed fin is arranged on the fixed frame, and a first disassembly rod is slidably arranged on the fixed fin. The tail end of the first disassembly rod is provided with a first pressing plate outward. An installation frame is arranged on the adjusting screw rod above the fixed frame. A bearing body is arranged between the installation frame and the adjusting screw rod. A second disassembly rod is slidably and adjustably arranged on the installation frame, and a second pressing plate is arranged on the inner side of the second disassembly rod. The utility model can disassemble the situation where the bearing outer ring is stuck in the bearing seat, and has the advantages of simple structure, flexible adjustment, wide application range, uniform force during disassembly, and reduced damage.

[0004] Based on the retrieval of the above patent and the discovery of equipment in the prior art, when the above equipment is applied, although it can solve the problem that during the use of bearings, wear will occur due to rotation, and over time, the bearings will be damaged. After problems occur in the bearings of some wheel parts such as tricycles, abnormal noises will occur when the wheels move, affecting the smoothness and stability during wheel rotation. Therefore, it is necessary to replace the damaged bearings. However, when replacing, the outer ring of the bearing is stuck in the bearing seat and is not easy to remove. Most of the existing methods are to remove it by electric welding. However, using the electric welding method to remove it easily causes damage at the oil port, resulting in oil leakage in the future. In addition, some people use the knocking method to remove it. However, the knocking method will cause uneven stress on the bearing seat on the external vehicle and the damaged outer ring of the bearing, easily causing deformation and damage of the bearing seat. But during the use process, since the inner and outer rings of the bearing are usually connected by interference fit, when separating the inner and outer rings of the bearing, after the outer clamping frame and the inner clamping frame clamp the bearing, then rotate the screw rod to make the inner clamping frame move upward. However, the frictional force of the interference fit during the separation process of the inner and outer rings of the bearing makes it very laborious to separate the inner and outer rings.

A spring is fixedly connected to the front of the knocking block. The other end of the spring is fixedly connected to the front side of the inner wall of the main body block. A traction rope is fixedly connected to the front of the knocking block. The other end of the traction rope penetrates through the bottom of the front of the main body block and is fixedly connected to the bottom of the reciprocating rod. A transmission mechanism is fixedly connected to the top of the rotating rod.

[0012] Preferably, a positioning ring is sleeved on the top of the surface of the traction rope, and the back surface of the positioning ring is fixedly connected to the top of the front surface of the main body block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging a knocking block, when the user rotates the rotating rod to disassemble the bearing by using the outer clamping frame and the inner clamping frame, the rotating rod pushes the reciprocating rod from the vertical state to the horizontal state, and at the same time, the knocking block is pulled through the traction rope to compress the spring. When the rotating rod passes through the reciprocating rod, the spring resilience pushes the knocking block to reset and knock the bearing, solving the problem that since the inner and outer rings of the bearing are usually connected by interference fit, but when separating the inner and outer rings of the bearing, after the outer clamping frame and the inner clamping frame clamp the bearing and then rotate the screw rod to make the inner clamping frame move upward, the interference fit friction force during the separation of the inner and outer rings of the bearing makes it very laborious to separate the inner and outer rings, achieving the effect of assisting in disassembly.

[0015] 2. The utility model sets up a transmission mechanism. After the user clamps the bearing with the outer clamping frame and the inner clamping frame, the user rotates the screw to pull the inner ring of the bearing downward by rotating the inner clamping frame. As the screw rotates, the large gear rotates together, and drives the small gear to rotate through the internal toothed belt. The gear ratio difference between the large gear and the small gear is used to make the rotating rod rotate rapidly, and repeatedly push the reciprocating rod from a vertical state to a horizontal state. During the process, the traction rope repeatedly pulls the knocking block, squeezing the spring to generate a rebound force. The spring rebound force repeatedly pushes the knocking block to reset, and at the same time uses the traction rope to drive the reciprocating rod to reset, receiving the repeated push of the rotating rod, thereby repeatedly knocking the bearing, destroying the static friction when the bearing is interference fit, thereby reducing the strength of the user to use the outer clamping frame and the inner clamping frame to remove the inner and outer rings of the bearing.

[0016] 3. The utility model provides a butterfly nut. When the outer clamping frame and the inner clamping frame clamp bearings of different diameters, in order to ensure that the striking block can strike the bearing, the user pulls the extension block along the trajectory of the base block, thereby adjusting the position of the main block and the striking block, and bringing the striking block into contact with the bearing. Then, the butterfly nut is rotated to fit and tighten the base block, so that the extension block is limited and fixed by the butterfly nut, thereby achieving the goal that the striking block can adapt to bearings of different diameters for striking, and there will be no tooth disengagement between the pinion and the inner toothed belt due to the unstable connection between the extension block and the base block.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 4 shown, a bearing outer ring disassembly and assembly tool provided by the present utility model includes an outer clamping frame 1, an inner clamping frame 2, and a screw rod 3. The screw rod 3 is movably connected to the inner wall of the outer clamping frame 1 through a bearing body. The inner wall of the inner clamping frame 2 is threadedly connected to the surface of the screw rod 3. A base block 4 is fixedly connected to the front surface of the outer clamping frame 1. An extension block 5 is slidably connected to the surface of the base block 4. The front side of the top of the extension block 5 is movably connected to a rotating rod 6 through a pin. The front surface of the extension block 5 is movably connected to a reciprocating rod 7 through a pin. The right side of the rotating rod 6 is movably connected to the left side of the reciprocating rod 7. A main body block 8 is fixedly connected to the bottom of the extension block 5. A knocking block 9 is slidably connected to the inner wall of the main body block 8. A spring 10 is fixedly connected to the front surface of the knocking block 9. The other end of the spring 10 is fixedly connected to the front side of the inner wall of the main body block 8. A traction rope 11 is fixedly connected to the front surface of the knocking block 9. The other end of the traction rope 11 penetrates through the bottom of the front surface of the main body block 8 and is fixedly connected to the bottom of the reciprocating rod 7. A transmission mechanism 12 is fixedly connected to the top of the rotating rod 6.

[0024] Refer to Figure 1 , the transmission mechanism 12 includes a small gear 121. The bottom of the small gear 121 is fixedly connected to the top of the rotating rod 6. A large gear 122 is provided at the top of the outer clamping frame 1. The inner wall of the large gear 122 is fixedly connected to the top surface of the screw rod 3. An internal gear belt 123 is provided at the top of the large gear 122. The large gear 122 and the small gear 121 are meshed and connected through the internal gear belt 123.

[0025] As a technical optimization solution of the present invention, a transmission mechanism 12 is set. After the user clamps the bearing with the outer clamping frame 1 and the inner clamping frame 2, the inner clamping frame 2 is pulled downward by rotating the screw 3. As the screw 3 rotates, the large gear 122 rotates together, and drives the small gear 121 to rotate through the internal toothed belt 123. The gear ratio difference between the large gear 122 and the small gear 121 is used to make the rotating rod 6 rotate rapidly, and repeatedly push the reciprocating rod 7 from a vertical state to a horizontal state. During the process, the traction rope 11 repeatedly pulls the knocking block 9, squeezing the spring 10 to generate a rebound force. The rebound force of the spring 10 repeatedly pushes the knocking block 9 to reset, and at the same time uses the traction rope 11 to drive the reciprocating rod 7 to reset, and receives the repeated push of the rotating rod 6, thereby repeatedly knocking the bearing, destroying the static friction when the bearing is interference fit, thereby reducing the strength of the user to use the outer clamping frame 1 and the inner clamping frame 2 to disassemble the inner and outer rings of the bearing.

[0026] refer to Figure 1 The rear sides of both sides of the extension block 5 are provided with butterfly nuts 13, and the inner threads of the butterfly nuts 13 penetrate to both sides of the inner wall of the extension block 5 and are movably connected to both sides of the base block 4.

[0027] As a technical optimization solution of the present invention, by setting a butterfly nut 13, when the outer clamping frame 1 and the inner clamping frame 2 are clamped to bearings of different diameters, in order to ensure that the knocking block 9 can knock the bearing, the user pulls the extension block 5 along the trajectory of the base block 4, thereby adjusting the position of the main block 8 and the knocking block 9, and making the knocking block 9 contact with the bearing, and then rotates the butterfly nut 13 to fit and tighten it with the base block 4, so that the extension block 5 is limited and fixed by the butterfly nut 13, thereby achieving the goal that the knocking block 9 can adapt to bearings of different diameters for knocking, and there will be no tooth disengagement between the pinion 121 and the inner tooth belt 123 due to the unstable connection between the extension block 5 and the base block 4.

[0028] refer to Figure 1 and Figure 2 A slide groove 14 is provided on the right side of the top of the outer clamping frame 1, and a slider 15 is slidably connected to the inner wall of the slide groove 14. A screw rod 16 is provided on the top of the right side of the outer clamping frame 1. The left side thread of the screw rod 16 passes through the left side of the slider 15 and is movably connected to the left side of the inner wall of the slide groove 14 through an axle pin. The top of the slider 15 is movably connected to a fastening gear 17 through an axle pin, and the fastening gear 17 is meshed with the internal toothed belt 123.

[0029] As a technical optimization solution of the present utility model, by providing a sliding groove 14, a sliding block 15, a screw rod 16 and a fastening gear 17, when the knocking block 9 needs to be adjusted according to bearings of different diameters, the small gear 121 will move together, so that a section of length of the internal tooth belt 123 needs to be reserved for adapting to the transmission between the large gear 122 and the small gear 121. To keep the internal tooth belt 123 continuously in a taut state and prevent the internal tooth belt 123 from disengaging from the large gear 122 and the small gear 121, when the user adjusts the distance between the large gear 122 and the small gear 121, the screw rod 16 is rotated to make the sliding block 15 move along the track of the sliding groove 14, so that the fastening gear 17 moves, thereby adjusting the internal tooth belt 123, making the internal tooth belt 123 in a taut state, which is more conducive to the transmission between the large gear 122 and the small gear 121, thus achieving the effect that the internal tooth belt 123 can make corresponding adjustments according to bearings of different diameters, and improving the adaptability of the internal tooth belt 123.

[0030] Reference Figure 1 , a cross-shaped belt pressing rod 18 is fixedly connected to the top of the large gear 122, and the bottom of the cross-shaped belt pressing rod 18 is movably connected to the top of the internal tooth belt 123.

[0031] As a technical optimization solution of the present utility model, by providing the cross-shaped belt pressing rod 18, when the user rotates the screw rod 3 to drive the large gear 122 to rotate and then uses the internal tooth belt 123 to transmit power to the small gear 121, during the rotation of the large gear 122, the cross-shaped belt pressing rod 18 rotates together and always presses the internal tooth belt 123, preventing the internal tooth belt 123 from disengaging from the large gear 122 during the power transmission between the large gear 122, the small gear 121 and the fastening gear 17 due to the rotational force, so as to avoid the loss of power transmission, thereby improving the stability when the large gear 122 drives the small gear 121 through the internal tooth belt 123.

[0032] Reference Figure 3 and Figure 4 , the bottom of the front surface of the main body block 8 is movably connected to a roller 19 through a shaft pin, and the surface of the roller 19 is slidably connected to the top of the traction rope 11.

[0033] As a technical optimization solution of the present utility model, by providing the roller 19, when the traction rope 11 is repeatedly drawn out from and retracted into the inner wall of the main body block 8 by the resilience of the reciprocating rod 7 and the spring 10, the traction rope 11 contacts the roller 19, and then the roller 19 rotates and bends at the actual contact surface with the roller 19, thereby preventing the traction rope 11 from directly bending at the edge of the inner wall of the main body block 8 and being repeatedly rubbed by the sharp corners at the edge, thus avoiding the phenomenon that the traction rope 11 is severely worn and damaged and broken, thereby improving the service life of the traction rope 11.

[0034] ReferenceFigure 1 and Figure 3 A positioning ring 20 is sleeved on the top surface of the traction rope 11, and the back surface of the positioning ring 20 is fixedly connected to the top of the front surface of the main body block 8.

[0035] As a technical optimization scheme of the present utility model, by setting the positioning ring 20, when the reciprocating rod 7 pulls out the traction from the inner wall of the main body block 8 and bends it through the bending point provided by the roller 19, the traction rope 11 moves along the trajectory of the inner wall of the positioning ring 20 together, and during the movement, the actual contact surface between the traction rope 11 and the positioning undergoes bending. At the same time, the traction rope 11 that has not entered the inner wall of the positioning ring 20 remains in a straight state, thereby preventing the traction rope 11 pulled when the reciprocating rod 7 is pushed from the vertical state to the horizontal state by the rotating rod 6 from being in an overall inclined state and thus unable to be bent by the bending point provided by the roller 19, resulting in the traction rope 11 bending at a position not covered by the roller 19 and bending at the sharp edges on both sides of the roller 19, so that the effect of the roller 19 preventing the traction rope 11 from being worn by the sharp edges is improved, thereby enhancing the effect of the roller 19 in preventing the traction rope 11 from being worn and damaged by the sharp edges.

[0036] The working principle and usage process of the present utility model: When in use, the user clamps the bearing to be disassembled by means of the outer clamping frame 1 and the inner clamping frame 2. The user adjusts the extension block 5 to ensure that the knocking block 9 contacts the bearing, and then rotates the butterfly nut 13 to make the butterfly nut 13 abut against the base block 4, thereby limiting and fixing the extension block 5. At the same time, as the extension block 5 moves, the distance between the large gear 122 and the small gear 121 changes, causing the internal tooth belt 123 for transmitting the rotational force of the large gear 122 to the small gear 121 to become loose or overly taut. At this time, rotate the screw rod 16 to drive the slider 15 to move along the trajectory of the chute 14, thereby adjusting the internal tooth belt 123 by means of the fastening gear 17 to keep the internal tooth belt 123 in the best transmission effect. Then, the screw rod 3 can be rotated. As the screw rod 3 rotates, the outer clamping frame 1 moves upward, and at the same time, the large gear 122 rotates together, and drives the small gear 121 to rotate through the internal tooth belt 123. And by using the gear ratio difference between the large gear 122 and the small gear 121, the rotating rod 6 rotates rapidly and repeatedly pushes the reciprocating rod 7 from the vertical state to the horizontal state. During this process, the traction rope 11 repeatedly pulls the knocking block 9, compresses the spring 10 to generate a resilience force, and the resilience force of the spring 10 repeatedly pushes the knocking block 9 to reset. At the same time, the traction rope 11 is used to drive the reciprocating rod 7 to reset and receive the repeated push of the rotating rod 6, thereby repeatedly knocking the bearing, destroying the static friction force during the interference fit of the bearing, reducing the strength of the outer clamping frame 1 and the inner clamping frame 2 for disassembling the inner and outer rings of the bearing, and thus having the advantage of assisting in disassembly.

[0037] In summary, for the bearing outer ring disassembly and assembly tool, by setting the knocking block 9, when the user rotates the rotating rod 6 to disassemble the bearing using the outer clamping frame 1 and the inner clamping frame 2, the rotating rod 6 pushes the reciprocating rod 7 from the vertical state to the horizontal state. Meanwhile, the traction rope 11 pulls the knocking block 9 to squeeze the spring 10. When the rotating rod 6 passes through the reciprocating rod 7, the spring 10 rebounds to push the knocking block 9 back to its original position to knock the bearing, solving the problem that since the inner and outer rings of the bearing are usually connected by interference fit, but when separating the inner and outer rings of the bearing, after the outer clamping frame and the inner clamping frame clamp the bearing and then rotate the screw rod to move the inner clamping frame upward, the interference fit friction during the separation of the inner and outer rings of the bearing makes it very laborious to separate the inner and outer rings.
