Powder metallurgy synchronizer gear hub

Abstract

The invention discloses a powder metallurgy synchronizer gear hub, which comprises a gear hub body and gear hub outer side oil storage splines; the gear hub outer side oil storage splines are fixedly installed on the periphery of the outer side of the gear hub body at equal angles; and spline axial grooves are arranged at the positions, located on the gear hub body, of equal-angle gaps of the three gear hub outer side oil storage splines; and a sleeve installation inner ring is arranged in the middle of the interior of the gear hub body, and a fan-shaped weight reduction groove is arranged at the position, located on the inner side of the circumference of the gear hub body, of the outer side of the sleeve installation inner ring. According to the powder metallurgy synchronizer gear hub provided by the invention, a positioning guide groove installation structure is installed, so that there is no slight angle of relative rotation with a drive shaft spline in the circumferential direction, when the sleeve installation inner ring shakes, a good stabilizing effect is achieved, the overall strength of a stable connecting cylinder is ensured through shaft reinforcing ribs on the outer side of the sleeve installation inner ring, and when the gear hub body makes contact with the outside, friction damage is effectively reduced through a gear hub outer side oil storage spline structure on the outer side of the gear hub body.

Description

Technical field [0001] The present invention relates to the field of powder metallurgy, in particular a powder metallurgy synchronizer. Background technique [0002] Powder metallurgy is a process technology for making metal powder or using metal powder as a raw material, forming and sintering, manufacturing metal materials, composites, and various types of articles. Powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biological, new energy, information and nuclear industry. [0003] Powder metallurgical synchronizer nibwise because the synchronizer usually occurs in the working state, it cannot be effectively stabilized, and the weight and size of the powder metallurgical synchronizer hub are increasing, so as to rub the friction of the synchronizer. The force will also increase, so sharp friction can cause friction damage, so that it affects the life of the synchronizer. Inventive content [0004] It is an object of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a powder metallurgy synchronizer gear hub to solve the problem that the powder metallurgy synchronizer gear hub proposed in the above background technology usually vibrates in the working state, cannot effectively and stably mesh, and the powder metallurgy synchronization When the weight and size of the gear hub of the synchronizer are increasing, the friction force of the gear hub of the synchronizer will also increase correspondingly.
