Drive gear installation moment and bearing pretension moment shim adjusting, measuring and selecting system and method

Abstract

The invention relates to a measuring method and a measuring system of a driving gear mounting distance adjusting spacer and a driving gear bearing pre-tightening torque adjusting spacer of an integrated main reducer assembly. The measuring system comprises a first detection service position for completing axial data measurement of a combination piece of an internal bearing and an external bearing of the driving gear, and a shell of the main reducer, a second detection service position for completing data measurement of the combination piece of the internal bearing and the external bearing of the driving gear, and a rigid distance sleeve and an electronic control system; an induction signal of a displacement sensor at the first detection service position is converted to obtain a value of the axial data measurement of the combination piece of the internal bearing and the external bearing of the driving gear, and the shell of the main reducing gear; the induction signal of the displacement sensor at the second detection service position is converted to obtain a value of the axial data measurement of the combination piece of the internal bearing and the external bearing of the driving gear and the rigid distance sleeve; and the desired spacer value is obtained by computing with a mathematical model program. The technical scheme helps eliminate interference of human factors and improve measurement precision.

Description

technical field [0001] The invention relates to a method for measuring and selecting the driving gear installation distance adjusting pad and the driving gear bearing pretightening torque adjusting pad in the integral final drive assembly, which is the core component of the automobile drive axle assembly, and to realize the measurement and selection Method system device. Background technique [0002] The main body of the automobile drive axle assembly includes the differential sub-assembly, the core components of the final reducer assembly, the axle shaft, the axle housing, the wheel hub, the brake drum and the brake and other main components. The assembly quality of main reducer assembly and differential sub-assembly is a key item that affects the comprehensive quality of automobile drive axle assembly products. At present, the measurement selection of the driving gear installation distance adjusting gasket and the driving gear bearing pretightening torque adjusting gasket...

AI Technical Summary

Problems solved by technology

At present, the measurement selection of the driving gear installation distance adjusting gasket and the driving gear bearing pretightening torque adjusting gasket of the driving and passive gear pairs is still in the manual offline detection method, which involves too many human factors in the assembly operation. It often leads to the emergence of unqualified products, which must be reworked in time. The detection accuracy is low, and it is difficult to become a high-quality detection technology for auxiliary automobile drive axle assembly production lines.
