An Analysis on Contact Line Performance of Offset Cylindrical Worm Gearing
Based on the theory of gear mesh, the contact line equation of involute offset cylindrical worm gearing, which is consisted of an involute helical gear with few teeth and a face gear in substance, is obtained. Furthermore, in order to investigate the influence of design parameters on the performance of contact line, numerical simulation of which is carried out. Analysis results indicate that an appropriate increase in helix angle and modulus as well as the teeth number of worm, reduction in the teeth number of worm gear can make the contact line performance better.
