Abstract: The main reducer is the key component of reducing speed and increasing torque in the automobile axle transmission system, and the main component of the main reducer is the main reducer shell assembly, and the differential bearing cover of the assembly has the function of installing bearings and positioning, but the phenomenon of vibration of the positioning pin of the differential bearing cover exists for a long time. This paper introduces a solution to eliminate the machining vibration marks of the differential bearing cover positioning pin of the main reducer housing assembly. By improving the tool structure, cutting parameters, tooling, etc, the machining vibration marks are completely eliminated, the scrap rate is effectively reduced, and the product quality is improved.

Key words: Main reducer assembly; Differential bearing cover; Vibration marks; Cutting parameters
