This paper summarizes the model of load distribution in the tooth direction of, summarizes the method of uniform load distribution by consulting literature, and discusses the advantages and disadvantages of tooth direction modification of helical gear. The scheme of tooth direction modification is based on the full understanding of helical gear modification, in-depth discussion of helical gear modification principle and theoretical calculation of modification amount.
According to the calculation results, the gear is re modeled and assembled by using proe software, and the dynamic contact analysis of helical gear is carried out by using ANSYS software. Analyze and compare the results before and after reshaping. Through the comparison before and after modification, the conclusion is drawn that the problem of uneven load distribution of helical gear teeth is solved.
