Study on the Meshing Feature and Contact Strength of WN Gear Driving in Load Bearing
According to characteristics of WN gear multi-point meshing and double-arc tooth contact, the finite element analysis model of the WN gear drive is established by Pro/E and ANSYS modeling techniques. The contact way and meshing feature of the WN gear under the different conditions and parameters are studied by three-dimensional dynamic meshing simulation analysis of gear drive. The analysis model of contact strength at loading driving is established by three dimensional geometric contact characteristics and elastic deform theory. Impact of helix angle and center distance error in the calculation of WN gear contact strength on maximum contact stress is analyzed. The results show that increase of the helix angle and a slight decrease of the center distance can improve the contact strength.
