Tolerance optimization design of RV reducer's cycloid-pin gear pair considering multiple targets

Abstract

In this paper, a multi-objective optimization model for the processing cost, quality loss and tolerance cost sensitivity of RV reducer’s cycloid-pin gear pair is constructed. The tolerance range is constrained based on the accuracy requirement and the actual machining capacity, and the design requirements of the gear pair clearance and allowable backlash are considered comprehensively. The tolerance optimization design of cycloid-pin gear pair is carried out by using NSGA-Ⅱ algorithm. The effectiveness and feasibility of tolerance optimization design are verified by comparing and analyzing the results before and after optimization.
