AI Technical Summary

Problems solved by technology

The existing gears do not have a heat dissipation structure. If the heat generated by friction with the shaft during the gear movement is not dissipated in time, it will lead to increased wear and deformation of the gears, which will affect its transmission stability and service life.

Abstract

The invention discloses a novel plastic gear which comprises a gear body. A shaft hole is arranged in the center of the gear body, at least three fan-shaped straight slots are arranged on the gear body and encircle the shaft hole, radiating grooves are arranged on the shaft hole, an abrasion-resistant layer is arranged in the shaft hole, and the radiating grooves are arranged in centers of lower surfaces of the fan-shaped straight slots. The novel plastic gear is provided with the fan-shaped straight slots and the radiating grooves, accordingly, heat generated when the gear moves and rubs with a shaft can be dissipated timely, and problems of aggregation of abrasion of the gear and deformation caused by high heat are solved. Besides, the novel plastic gear is high in abrasion resistance, stable in transmission performance and long in service life.

Description

technical field [0001] The invention relates to a gear, in particular to a novel plastic gear, which belongs to the technical field of mechanical transmission components. Background technique [0002] Gears are common mechanical parts in people's lives, which are transmitted through mutual meshing. The plastic gear is a gear made of plastic. Plastic gears are lightweight, low cost and easy to process. Plastic gears are widely used in textiles, machine tools, plate making, instrumentation, food and other industries. The existing gears do not have a heat dissipation structure. If the heat generated by the friction between the gear and the shaft during the movement is not dissipated in time, it will lead to aggravated wear and deformation of the gear, which will affect its transmission stability and service life. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to propose a new type of plastic gear with good...
