Description

Technical Field

[0001] This utility model relates to the field of synchronous belt pulley technology, specifically a synchronous belt pulley with anti-deviation function. Background Technology

[0002] The synchronous belt pulley with anti-deviation function disclosed in CN220505723U includes a synchronous belt pulley body, a synchronous belt body connected to the outer side of the synchronous belt pulley body, and a limit component fixedly connected to the middle of the synchronous belt pulley body. The synchronous belt pulley body has several V-shaped grooves on its outer side, and a toothless shaft step is connected to a fixed block at one end of the synchronous belt pulley body. It can achieve the function of preventing synchronous belt deviation by fixing the limit component in the middle of the synchronous belt pulley body, thus solving the problem of accidents caused by synchronous belt deviation. By fixing the limit component in the middle of the synchronous belt pulley body, it can reduce costs by eliminating the need to process the flange, and solve the problem of long processing time and low work efficiency caused by the cumbersome traditional manufacturing process.

[0003] Although the technical solution of timing pulleys with anti-deviation function can improve processing efficiency and reduce costs, the defects are also more obvious. For example, during the use of timing pulleys, it is not easy for personnel to constrain and limit the spacing between timing pulleys, which can easily cause the timing pulleys to shift position and affect their subsequent use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a synchronous pulley with anti-deviation function, which solves the problem that during the use of synchronous pulleys, it is difficult for personnel to constrain and limit the spacing between them, which leads to the synchronous pulleys being prone to positional deviation and affects their subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a synchronous belt pulley with anti-deviation function, comprising a pulley body, a synchronous belt sleeved on the outer surface of the pulley body, a screw threadedly connected to the shaft center on the front side of the pulley body, a connecting piece threadedly connected to the surface of the screw, a constraint component provided on the front side of the connecting piece, and a rack provided on the surface of the pulley body.

[0006] In one specific embodiment, the constraint assembly includes a rotating wheel rotatably connected to the front axis of the connecting piece, a constraint belt being sleeved on the outer surface of the rotating wheel, and a driven wheel being provided on the other side inside the constraint belt.

[0007] In one specific embodiment, a circular block is fixedly installed at the center of the axis on the front of the rotating wheel, and a connecting block is provided on the other side of the front of the circular block.

[0008] In one specific embodiment, a support rod is rotatably connected to the front of the connecting block, and the other end of the support rod is rotatably connected to the front of the driven wheel.

[0009] In one specific embodiment, a bubble balancer is fixedly connected to the front of the support rod, and an anti-oxidation film is attached to the outer surface of the bubble balancer.

[0010] In one specific embodiment, the back structure of the wheel body is the same as the front structure of the wheel body, and they are arranged symmetrically.

[0011] In one specific embodiment, the constraint belt is made of an elastic material, and the outer surface of the synchronization belt is covered with a waterproof membrane.

[0012] Compared with the prior art, this utility model provides a synchronous belt pulley with anti-deviation function, which has the following beneficial effects:

[0013] In the technical solution disclosed in this utility model, the constraint component and the wheel body are used in cooperation. When the operator uses the wheel body and the synchronous belt, the rotating wheel cooperates with the constraint belt to constrain the preload of the wheel body and the synchronous belt, thereby fixing the synchronous belt and the wheel body and reducing the occurrence of accidental deviation of the wheel body.

[0014] A circular block is fixedly installed at the center of the axis on the front of the rotating wheel as provided by this utility model. A connecting block is provided on the other side of the front of the circular block. A support rod is rotatably connected to the front of the connecting block. The other end of the support rod is rotatably connected to the front of the driven wheel. When the wheel is used by the user, the support rod is driven to rotate as the rotating wheel rotates. This causes the support rod to continuously limit the distance between the two wheels, thereby reducing the occurrence of the wheels coming off the synchronous belt during operation.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a synchronous belt pulley with anti-deviation function includes a pulley body 1, a synchronous belt 2 sleeved on the outer surface of the pulley body 1, a screw 3 threadedly connected to the shaft center on the front of the pulley body 1, and a connecting piece 4 threadedly connected to the surface of the screw 3. The screw 3 and the connecting piece 4 facilitate the disassembly of the constraint component 5 by personnel. The constraint component 5 is provided on the front of the connecting piece 4, and a rack 6 is provided on the surface of the pulley body 1. The rack 6 is provided to facilitate cooperation with the synchronous belt 2.

[0023] The specific problem addressed in this embodiment is the difficulty in constraining the spacing between synchronous pulleys during use, which leads to positional misalignment and affects subsequent use. This invention utilizes the cooperative use of the constraint component 5 and the pulley body 1. During use of the pulley body 1 and the synchronous belt 2, the rotating pulley 51, in conjunction with the constraint belt 52, constrains the preload of the pulley body 1 and the synchronous belt 2, thus fixing the synchronous belt 2 and the pulley body 1 and reducing the possibility of accidental deviation of the pulley body 1.

[0024] The constraint assembly 5 includes a rotating wheel 51 rotatably connected to the center of the front of the connecting piece 4. A constraint belt 52 is sleeved on the outer surface of the rotating wheel 51. A driven wheel 53 is provided on the other side inside the constraint belt 52. In this specific embodiment, a circular block 7 is fixedly installed at the center of the front of the rotating wheel 51. A connecting block 8 is provided on the other side of the front of the circular block 7. A support rod 9 is rotatably connected to the front of the connecting block 8. The other end of the support rod 9 is rotatably connected to the front of the driven wheel 53. When the wheel 1 is used by the personnel, the support rod 9 is driven to rotate as the rotating wheel 51 rotates, so that the support rod 9 continuously restricts the distance between the two wheels 1, thereby reducing the occurrence of the wheel 1 disengaging from the synchronous belt 2 during operation.

[0025] In this specific embodiment, a bubble balancer 10 is fixedly connected to the front of the support rod 9. With the bubble balancer 10, when personnel need to observe whether the wheel 1 is balanced, they can observe the bubble balancer 10 to predict whether the wheel 1 will tilt. The outer surface of the bubble balancer 10 is covered with an anti-oxidation film, which improves the anti-oxidation performance of the bubble balancer 10. The back structure of the wheel 1 is the same as the front structure of the wheel 1 and is symmetrically arranged. The constraint belt 52 is made of elastic material. The outer surface of the synchronous belt 2 is covered with a waterproof membrane, which improves the waterproof performance of the synchronous belt 2.

[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
