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.

Embodiment
[0036] EXAMPLIC: The hub body 1 is mainly fixed on the inner ribs of the inner ring 8 in the inner ring 8 in the sleeve, which is effectively fixed on the transmission shaft of the powder metallurgy synchronizer, and the inner spline of the hub is in the intermediate intermediate spline card. The groove 7 is oriented with the positioning guide of the positioning guide, and the eighteen positioning guide grooves 10 is symmetrically distributed in the inner side of the hub, thereby forming a tight fit with the powder metallurgical synchronizer drive shaft spline to make the hub The inner spline 3 and the drive shaft spline cannot have a relative rotation of fine angles in the circumferential direction, which avoids the jitter impact during operation.
[0037] The three sectors of the hub body 1 reduce the groove 4 space, so that the overall weight is effectively reduced, so that the overall friction force is reduced, and the angle of three sector reduction grooves 4 is disposed on t...

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 ...
