Tip-rem modification for full tooth surface pattern and require no edge contact of high loaded capacity cycloidal hypoid gears

The full tooth surface pattern and require no edge contact design of cycloid bevel gears based on Tip-rem is a novel gear optimization design method, which aimed at optimizing contact performance of gears and preventing edge contact, thus improving the transmission accuracy and life of gears. The method is based on the principles of full contact pattern design and require no edge contact design, and by modifying the root of tool, according to coordinate transformation relationship of machining, we get the tooth face with Tip-rem, so as to maximize contact pattern of the tooth face from NLTCA(numerical loaded contact analysis), and there is no edge contact during gear meshing process. Example results prove that the present method can achieve design of maximizing the full tooth face contact pattern under heavy loaded no edge contact, and at the same time reduce the maximum contact pressure to improve the load carrying capacity.
