Method of face gear grinding-honing machining based on aviation environment

Face gear drives become the main direction of research for aeronautical drives because of their special advantages. The equation of face gear tooth surface was established based on the face gear transmission theory. For improving the precision machining technology of face gear, the method of face gear grinding-honing machining was put forward. The applied coordinate systems of face gear were set up and then the special grinding tool for face gear was developed based on special face gear numerical control grinding machine, influence of face gear grinding, slotted technique and the honing theory of traditional gear. In addition, flexible honing tool was designed. And then the tool used for grinding-honing parts machining was manufactured. The special tool was used to do face gear grinding-honing machining experiment, and then surface quality inspection on face gear was conducted, such as the detection of surface roughness, residual stress testing and observation of surface micro texture. The analysis of the surface quality detection results proves this method is reliable.
