Analysis and Design of Differential bevel gear

Abstract

Differential bevel gear strength calculation, The main purpose is to evaluate whether the gear can meet the strength and life requirements under load; There is a mature theoretical gear strength calculation formula, However, due to the theoretical gear strength calculation, the tooth shape is different from the actual tooth shape, In turn, the theoretical calculation strength is different from the actual manufacturing strength. This research is based on existing products in the industry, Calculate the theoretical strength using the parameters of this product, And use the same bevel gear forging mathematical model as the product, Calculate gear strength through dynamic software LS-Dyna, Comparing the gear strength with the actual tooth profile and the gear strength of the actual tooth profile, The gear strength obtained by LS-Dyna can be approximated by the theoretical calculation gear strength, In this way, you can quickly know at the beginning of the design whether the designed gear strength can withstand the load.
