Self-cleaning cylindrical gear for new energy electric logistics vehicle and manufacturing process of self-cleaning cylindrical gear

Abstract

The invention discloses a self-cleaning cylindrical gear for a new energy electric logistics vehicle and a manufacturing process of the self-cleaning cylindrical gear. The self-cleaning cylindrical gear for the new energy electric logistics vehicle comprises a connecting shaft, oil storage barrels, a tooth disc, a plurality of tooth holders, lubricating assemblies and cleaning assemblies. The tooth disc is installed at the end of the connecting shaft, and the tooth holders are installed on the circumferential face of the tooth disc in an annular matrix array mode. The cleaning assemblies are arranged on the two sides of each tooth holder correspondingly, and the lubricating assemblies are mounted at the tops of the tooth holders. Through arrangement of the cleaning assemblies, sliding blocks can slide along guide rods under stretching of contraction springs, and it can be guaranteed that one side of each scraper blade slides along one side of the corresponding tooth holder. In the meshing process, the scraper blades are extruded and contracted and reset, and inserting rods are inserted into rod holes. Under reciprocating operation of the scraper blades, dust and dirt on the surfaces of the tooth holders can be removed through the scraper blades, self-cleaning of the gear can be achieved when the gear rotates, and it is guaranteed that the gear is better meshed and can be continuously used for rotary meshing.

Description

technical field [0001] The invention relates to the field of gears, in particular to a self-cleaning cylindrical gear for a new energy electric logistics vehicle and a preparation process thereof. Background technique [0002] The gear mechanism of the cylindrical gear > When meshing transmission, there is a relatively large tangential relative sliding velocity along the tooth length direction, which will cause greater wear. On the other hand, the tooth profiles of the two wheels are in a point contact state, and the contact stress value It will greatly cause the curved surface to be fed prematurely, which will promote the wear of the gear teeth; [0003] Existing gears are widely used in mechanical equipment, but during the use of the gears, when the logistics vehicle is running, the circular gears mesh, and the accumulation of grease and debris generated by gear friction on the gear surface, the accumulation of grease and debris , will affect the gear meshing process, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-cleaning cylindrical gear for a new energy electric logistics vehicle and its preparation process, which solves the problem that when the logistics vehicle is running, when the circular gear meshes, oil dirt and debris generated by gear friction will accumulate on the gear surface , The accumulation of grease and debris will affect the gear meshing process, affect the transmission effect, and cause the transmission to falter, etc., reducing the service life of the gear.
