Synchronizer combination toothed ring machining method and special die thereof

Abstract

The invention discloses a synchronizer combination toothed ring machining method. In the machining method, outer tooth profiles, ring conical tooth faces and end face lock angles of synchronizer combination toothed rings are all machined by a stamping process. Only a stamping press and a special die are needed for manufacturing the synchronizer combination toothed rings by the machining method, equipment input is less, and accordingly production cost is saved; adjustment of machining process parameters is not needed, errors of human intervention are reduced, and production efficiency and product precision are improved; compared with forging, stamping has the advantages that production process is simple, and machining efficiency is high. The invention further discloses the special die used for the machining method.

Description

technical field [0001] The invention relates to the technical field of mechanical processing technology, in particular to a processing method for a synchronizer combined with a gear ring. The present invention also relates to a special mold for the above processing method. Background technique [0002] The synchronizer is a device that synchronizes the peripheral speed of a pair of gears to be meshed during the shifting process to achieve smooth shifting. The combined ring gear is the core component of the synchronizer, which can quickly achieve and maintain the same peripheral speed of the meshed gear and the corresponding engaged ring gear, and can also prevent the two from combining before reaching synchronization to prevent impact. [0003] The combined gear ring is a ring structure, which is fitted on the gear shaft through the through hole in the middle; the outer circumference of the combined gear ring has several tooth structures uniformly distributed, each tooth st...

Problems solved by technology

[0006] In the machining method, general-purpose machine tools with special fixtures or combination machine tools with special tooling and simple CNC machine tools are used. The chamfering process must be carried out with a dedicated CNC chamfering machine, and the equipment investment is large; and before indexing feed and cutting processing The parameters need to be adjusted manually, which is inefficient and prone to human error, which affects the processing accuracy

However, the process of forging method is more complicated, the process is longer, and it needs to use a large-tonnage extrusion machine, so the efficiency is low
