Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an anti-slip belt pulley for an air compressor. Background Art

[0002] Air compressor refers to an air compressor, which is a device used to compress gas. It usually uses reciprocating piston motion, rotating blades or rotating screws to introduce air into the compression, and the motor drives the pulley assembly to drive the blades or rotating screws to rotate. The pulley assembly is worn out after long-term operation, or the pulley assembly slips due to the instantaneous starting torque, which increases the wear and tear, resulting in the need for regular replacement;

[0003] The utility model with publication number CN214063719U discloses a pulley with an anti-slip structure. A stamping method is used to press a flower shape on the installation plane of the pulley body to match the drive shaft. During installation, only two parts need to be contacted and then gently rotated to make the flower shape match, which reduces the difficulty of installation, speeds up the installation, and reduces the production cost while maintaining the performance of the pulley body.

[0004] However, the above-mentioned pulley with anti-slip structure still has the following problems during actual use: although the flower shape is processed on the outside of the drive shaft to prevent slipping, when the pulley is rotating, the flower shape can only mesh with the inner side of the belt, and the instantaneous rotating drive shaft cannot be guaranteed to be always in meshing state with the belt, thereby aggravating the wear of the belt. At the same time, the belt vibrates due to insufficient tension during rotation, which is easy to cause slippage.

[0005] Therefore we propose an anti-skid air compressor pulley to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide an anti-skid air compressor pulley, which solves the problem that a flower shape is processed on the outer side of a drive shaft to prevent slipping. However, when the pulley is rotating, the flower shape can only mesh with the inner side of the belt, and the driving shaft that rotates instantly cannot be guaranteed to be always in a meshing state with the belt, thereby aggravating the wear of the belt. At the same time, the belt vibrates due to insufficient tension during rotation, which easily causes slippage and the like.
