Abstract
The utility model discloses a double-deck gear which comprises a plastic gear, a plastic shaft sleeve and a metal gear. The plastic gear is formed on an outer side of the metal gear through injection molding. The plastic shaft sleeve is formed on a surface of an inner hole of the metal gear through injection molding. The plastic gear and the plastic shaft sleeve are integrated through injection molding The plastic shaft sleeve is formed on the surface of the inner hole of the metal gear through injection molding so that a direct contact between the metal gear and a metal shaft is avoided, and therefore the double-deck gear solves the problem of heat generation through frictions and effectively prolongs service life.
Description
Technical field
The utility model relates to double-layer gear.
Background technique
By the double-layer gear that powder metallurgical gear and plastic gear combine, main at present through the processing of inserts Shooting Technique.Add man-hour, earlier the processing powder metallurgical gear is pressed into powder metallurgical gear in the mould of plastic gear then as inserts, at last injection moulding processing plastic gear again.This double-layer gear is when work; The endoporus of powder metallurgy directly contacts with metal shaft, and the bigger frictional force that can produce between metal gear and the metal shaft during work is in case the operating time is longer; Friction generates heat just makes plastic gear produce distortion easily, and working life is shorter.
The model utility content
The utility model technical problem to be solved provides a kind of double-layer gear, solves the problem of frictional heat between metal gear and the metal shaft, increases the service life.
In order to solve the problems of the technologies described above, the technological scheme that the utility model provided is: double-layer gear comprises plastic gear, plastic sleeve and metal gear; Said plastic gear is injection molded in the metal gear outside through mould; Said plastic sleeve is injection molded at the bore area of metal gear through mould; Said plastic gear and plastic sleeve are injection molded through the mould integral type.
Said metal gear is a powder metallurgical gear.
After having adopted technique scheme; The utlity model has following beneficial effect: the utility model generates plastic sleeve through the bore area injection moulding in metal gear; Avoided metal gear directly to contact, solved the problem of frictional heat, effectively prolonged working life with metal shaft.
