Abstract
Description
Technical Field
[0001] The utility model relates to the field of synchronous pulleys, and more specifically, to a staggered-tooth retaining-ring synchronous pulley. Background Art
[0002] A synchronous pulley generally refers to one made of materials such as steel, aluminum alloy, cast iron, brass, etc., and its inner hole has forms such as a round hole, a D-shaped hole, a tapered hole, etc. The synchronous pulley drive consists of a closed annular belt with equally spaced teeth on its inner peripheral surface and corresponding pulleys.
[0003] However, during its actual use, for example, when the existing synchronous pulley drive is in the process of transmission, foreign objects may enter the synchronous pulley, which will increase the wear between the transmission components of the synchronous pulley, thereby reducing the service life of the synchronous pulley drive. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiment of the present utility model provides a staggered-tooth retaining-ring synchronous pulley. By providing retaining edges on the teeth of the synchronous pulley body, the retaining edges are staggered at both ends of the teeth. Compared with the commonly used integral retaining edge, it is beautiful and lightweight. During the process of the teeth and slots of the synchronous pulley body being in transmission connection with the transmission components, the retaining edges on both sides can effectively prevent foreign objects from the outside from entering the transmission components, avoiding damage to the components caused by entering the inside of the synchronous pulley transmission components, and increasing the service life of the synchronous pulley.
[0005] To achieve the above object, the present utility model provides the following technical solution: A staggered-tooth retaining-ring synchronous pulley, comprising: a synchronous pulley body, and a plurality of teeth are integrally installed on the outer peripheral surface of the synchronous pulley body, and retaining edges are fixedly installed at both ends of the plurality of teeth in a staggered manner.
[0006] Further, an installation groove is provided at the center inside the synchronous pulley body for installing the synchronous pulley body through the installation groove.
[0007] Further, a plurality of tooth grooves are provided on the outer surface of the synchronous pulley body, and the inner wall of the tooth groove is an arc structure for mutual transmission with the synchronous belt through the tooth groove.
[0008] Further, the top height of the retaining edge is higher than the top height of the tooth, and the synchronous pulley is protected by the retaining edge.
[0009] The technical effects and advantages of the present utility model:
[0010] By arranging ribs on the latching teeth of the synchronous belt pulley body, the ribs are staggered at both ends of the latching teeth. Compared with the commonly used integral ribs, it is beautiful and light. During the transmission connection work between the latching teeth and the latching grooves of the synchronous belt pulley body and the transmission component, the ribs on both sides can effectively prevent foreign objects from entering the transmission component, avoid entering the interior of the synchronous belt pulley transmission component to cause damage to components, and increase the service life of the synchronous belt pulley.
