DESIGN OF A SPUR GEAR BASED ON THE RELATIVE CURVATURE CONTROL AND ANALYSIS OF ITS STRESS AND MESH STIFFNESS
The relative curvature of the spur gear mesh point is one of the key geometric parameters of the tooth profile
which has a significant impact on the stress distribution and mesh stiffness of the gear. Starting from the relevant research on constant relative curvature (CRC) gears
three types of non-involute spur gear tooth profiles were constructed based on the relative curvature control strategy considering the time-varying mesh characteristics of gears
and the mesh simulation of gear pairs was implemented. The influence of relative curvature control on the maximum contact stress
maximum bending stress
and mesh stiffness of gears was analyzed. The effectiveness of the control strategy was verified. This work provides some reference for the design of spur gears based on the relative curvature control.
