Abstract
Abstract. Based on the space curve meshing equation, a novel helical gear mechanism with improved geometry is presented. First, equations of the theoretical contact curves were derived based on the space curve meshing theory. Then, tooth surfaces with a concave–convex meshing form were constructed, depending on the contact curves. The tooth profiles were improved as the theoretical contact curves were corrected by predestining the designed transmission errors. The effect of the center distance error on the transmission errors was studied, and the effects of gear modifications on
transmission errors and maximum contact stresses were also investigated.
The results show that the transmission error curves of the improved gear
drive become much smoother. Maximum contact stresses of the improved
gear drive are decreased synchronously.
