Bearing Check Analysis for Automobile Transmission Based on the Software MASTA
As the main supporting drive components of the automobile transmission, the transmission bearings are mainly used to support the moving parts installed on the gear shaft, and to ensure the rotary precision of the gear shaft and the rotating parts, which plays an important role on transmission performance. Aiming at the existing problems of the traditional check method of bearing, the objective of this study is to take a five-speed transmission as an example, to accomplish the fatigue life analysis of the bearings of the automobile transmission based on the MASTA software. The simulation modeling of the transmission is built completely to simulate the actual load conditions and complete the process of analysis for the bearings. Analytical results show that using MASTA software can effectively perform the fatigue life analysis of the transmission bearings instead of the general conventional theoretical calculation method in the actual manufacturing process, moreover, the analysis results will provide theoretical basis for the overall optimization structural design of the automobile transmission.
