Analysis of the Influence of Parallelism Error on the Meshing Performance of Circular-Arc-Tooth-Trace Cylindrical Gears

摘要

In this paper, two types of point contact and line contact of spiral cylindrical gear transmission pair are studied and analyzed. The influences of the axis parallelism error and the center distance error on the contact area are analyzed. The numerical example shows that the line-contact transmission pair has larger contact area if the installation error is not considered. By using MATLAB software and simulation example, the influence of axis parallelism on contact area and meshing performance of spiral cylindrical gears under different error conditions are obtained.
