The greatest possibility of the conical involute gear is to use the straight conical involute gears instead of the bevel gears. However, the key technology to realize this usage is to establish a grinding method of the straight conical involute gears having a comparatively large cone angle. In this paper, three grinding methods to finish such a gear are developed. They are Niles-type infeed grinding, table sliding infeed grinding, and inclining work-arbor infeed, grinding. The principles and the available machines are described, the test results are discussed, and it is concluded that the most practical method is table sliding infeed grinding.
