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 the differential 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 switch are 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 application in the assembly process of the automobile final reducer to measure the gap between the upper half shaft gear and the lower half shaft gear of the differential and the left housing and the right housing of the differential so as to accurately select the differential speed. Measuring device and measuring method for spacers. Background technique [0002] The structure of the differential is as figure 1 As shown, it is composed of the right differential case 22, the upper half shaft gear 9, the upper shim 8a, the planetary gear 21, the cross shaft 24, the lower half shaft gear 13, the lower shim 14a and the left differential case 23. When assembling, it is necessary to select the appropriate upper shim 8a and lower shim 14a to ensure that there is a proper meshing gap between the planetary gear 21 and the upper half shaft gear 9 and the lower half shaft gear 13 in order to ensure the normal operation and Service life. ...
