Differential gear pad-choosing measuring system and measuring method

Abstract

The invention relates to a differential pad-selection measurement system and method, which are characterized in that: a differential left shell is arranged on a positioning bench, a lower simulation pad is arranged between the differential left shell and a lower semiaxis gear; planetary gears are sleeved on four ends of a cross axle of member to be measured and are arranged in a shaft hole of thedifferential left shell; a lower puller sleeve arranged in a shaft hole of the lower semiaxis gear is hung on the lower semiaxis gear through an upper edge shoulder of the lower puller sleeve, a measurement tappet is fixedly connected with the lower puller sleeve, a puller spring is arranged between the measurement tappet and the lower puller sleeve, a spring guide sleeve sleeves on the measurement tappet and is supported by the puller spring; an upper top board is arranged on the spring guide sleeve by press mounting manner; and a displacement sensor, a pressure sensor and a proximity switchare respectively arranged in a pressure driving body. The invention can automatically complete accurate measurement of thickness of the differential pad, and can increase product quality and production efficiency.

Description

technical field [0001] The invention relates to the measurement of the gap between the upper half shaft gear and the lower half shaft gear of the differential, the left shell of the differential, and the right shell of the differential, which are applied in the assembly process of the main reducer of the automobile, so as to accurately select the differential speed. The measuring device and measuring method of the gasket. Background technique [0002] The structure of the differential is as figure 1 Shown, be made up of differential gear right housing 22, upper side gear 9, upper gasket 8a, planetary gear 21, cross shaft 24, lower side gear 13, lower gasket 14a and differential gear left housing 23. When assembling, the appropriate upper gasket 8a and lower gasket 14a must be selected to ensure that there is a suitable meshing gap between the planetary gear 21, the upper side gear 9 and the lower side gear 13, so as to ensure the normal operation and operation of the parts....

Problems solved by technology

[0003] In the existing main reducer assembly process, it is generally carried out manually by assembly workers using general tooling. In this assembly process, the artificial randomness is large, resulting in unstable product quality and low production efficiency.
