Description

Technical Field

[0001] The utility model relates to the technical field of overrunning clutches, and particularly relates to an abrasion-resistant overrunning clutch for an automotive starter. Background Technique

[0002] An overrunning clutch, also known as a one-way bearing, is a basic mechanical transmission component that can only transmit power in one direction (usually clockwise or counterclockwise). Its main function is to ensure that the component connected to it can only rotate in a certain determined direction, while being locked in the other direction. When the power source changes the rotation direction, the overrunning clutch can automatically disengage the passive component, thus preventing power transmission.

[0003] The application number is CN202223208621.8, which discloses an abrasion-resistant overrunning clutch for an automotive starter. The utility model provides an abrasion-resistant overrunning clutch for an automotive starter, including an overrunning clutch body. A one-way inner ring is arranged at the center of the overrunning clutch body, and an inner arc block is sleeved outside the one-way inner ring. A one-way outer ring is arranged outside the inner arc block. A groove is formed between the inner arc block and the one-way inner ring, and an inner hole is formed in the one-way inner ring. The outer surface of the one-way outer ring is smooth, and the one-way outer ring is made of cast steel. An activity groove is formed at the front part of the inner arc block, and the groove and the activity groove are communicated with each other. The utility model can reduce the traction force required by the spring, ensure that the rollers will not come out or tilt, and at the same time help to reduce the sliding friction force received by the rollers, make the friction force received by the rollers more rolling friction force, convert the friction resistance received by the rollers, and improve the service life of the spring and the rollers.

[0004] For such an abrasion-resistant overrunning clutch for an automotive starter, including an overrunning clutch body. A one-way inner ring is arranged at the center of the overrunning clutch body, and an inner arc block is sleeved outside the one-way inner ring. A one-way outer ring is arranged outside the inner arc block. A groove is formed between the inner arc block and the one-way inner ring, and an inner hole is formed in the one-way inner ring. The outer surface of the one-way outer ring is smooth, and the one-way outer ring is made of cast steel. An activity groove is formed at the front part of the inner arc block, and the groove and the activity groove are communicated with each other. The existing technology has the problem of low service life. The closest prior art solves the problem of low service life. However, when this abrasion-resistant overrunning clutch for an automotive starter is in use, when the overrunning clutch rotates, the temperature of the overrunning clutch will rise, affecting the operation of the overrunning clutch, so there will be a problem of reduced working efficiency of the overrunning clutch. Therefore, we propose an abrasion-resistant overrunning clutch for an automotive starter to solve the above problems. Content of the Utility Model

[0005] To solve the above technical problems, the present utility model is achieved through the following technical solutions:

[0006] The present utility model is a wear-resistant one-way clutch for an automotive starter, including a one-way clutch main body.

The heat-resistant plate is located on the outer surface of the one-way clutch inner ring. Rollers are connected to the surface of the heat-resistant plate, and a one-way clutch outer ring is connected to the surface of the rollers. The rollers are located between the one-way clutch outer ring and the heat-resistant plate. A support block is connected to the inner surface of the one-way clutch outer ring, and a protection device is connected to the surface of the support block. The protection device is located on one side of the rollers.

[0007] Further, limiting rings are connected to both sides of the support block.

[0008] Further, there are ten groups of the support blocks.

[0009] Further, the protection device includes a support column. One end of the support column is connected to the support block, the other end of the support column is connected to a spring, and a sleeve is connected to the outer surface of the spring.

[0010] Further, the upper end of the support column is wider than the lower end.

[0011] Further, there are three groups of the protection devices on the surface of each support block.

[0012] Further, the surface of the heat-resistant plate is coated with lubricating oil.

[0013] The present utility model has the following beneficial effects:

[0014] (1) In the present utility model, by using the heat-resistant plate and connecting the heat-resistant plate to the surface of the one-way clutch inner ring, the influence of the temperature generated during the rotation of the one-way clutch main body on the operation of the one-way clutch main body can be reduced, ensuring the working efficiency of the one-way clutch main body.

[0015] (2) In the present utility model, by using the protection device, a support block is connected to the inner surface of the one-way clutch outer ring, and the protection device is connected to the surface of the support block. After the rollers are subjected to a force, there is a force on the protection device. This force moves downward through the sleeve, and the force is weakened by the spring in the sleeve, achieving the buffering effect of the rollers during operation through the protection device, avoiding the wear of the rollers during long-term force application, and increasing the service life of the one-way clutch main body.

[0016] (3) In the present utility model, by using lubricating oil and coating a layer of lubricating oil on the surface of the heat-resistant plate, the friction between the rollers and the heat-resistant plate is reduced, wear is decreased, and the service life is prolonged.
