本文采用较小基圆渐开线代替齿轮渐开线,创造出新的渐开线成形砂轮修整器。它的优点是能同时修砂轮两个齿面,能同时修基圆以下的非渐开线齿形部分,能磨修形齿轮,能共用基圆板,修整器结构简单。而为高效、经济的成形磨齿加工展示了新前景。 In this paper, a smaller base circle involute instead of gear involute, to create a new involute forming wheel dresser. The utility model has the advantages that the two tooth surfaces of the grinding wheel can be repaired at the same time, and the non-involute tooth-shaped parts under the repairing circle can be repaired at the same time, the gear can be worn and the base disc can be shared, and the structure of the dresser is simple. It shows a new prospect for efficient and economical forming and grinding.
