Abstract

The invention relates to a tooth chamfer tester of a tooth ring, and belongs to the technical field of tooth rings. The tester comprises a column arranged on a pedestal, the pedestal is supported by supporting legs, the pedestal is provided with a through hole for placing the tooth ring and at least three groups of spherical supporters, each group of spherical supporters supports the two side surfaces of a chamfer of the same tooth in the tooth ring, a positioning mandrel is further included, one end of the positioning mandrel is provided with a positioning cylinder matching the inner ring ofthe tooth ring, and the positioning mandrel and the positioning cylinder are arranged on the column in an up-down sliding way. Thus, detection time for the tooth chamber is shortened, the detection efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ring gears, in particular to a tooth chamfering inspection tool for ring gears. Background technique [0002] The ring gear in the automobile gearbox belongs to a transmission part with many structural elements and high requirements for shape and dimensional accuracy. [0003] In the prior art, in order to improve the reliability of the transmission, prevent gear loss, and improve the quality of the transmission assembly, most of the teeth in the ring gear are configured as inverted bevel teeth, and the inverted bevel teeth are involute teeth. In order to make the gear sleeve in the synchronizer engage with the ring gear without hindrance, a sharp angle is provided at the end of the inverted bevel tooth of the ring gear. Since the gear rotates at a high speed, the synchronizer gear sleeve It cannot be hung into the ring gear smoothly. If the synchronizer sleeve is forced to be hung into the ring gear, th...
