Short summary
A novel helical gear mechanism with improved geometry is proposed to reduce transmission errors. For the novel spiral gear mechanism with improved geometry, the maximal contact stresses change more smoothly and have a stronger bearing capacity. The results show that, under the same conditions, the gear in this paper improves the transmission accuracy, and the bearing capacity is also stronger.
