The invention relates to the technical field of worm and gear transmission, and provides a worm gear, a machining method and related equipment. The worm gear comprises a gear body and gear teeth distributed on the peripheral wall of the gear body, the gear teeth are oblique teeth, and the tooth surface of each gear tooth comprises a flat tooth surface and arc tooth surfaces distributed on the two sides of the flat tooth surface in the tooth direction of the gear teeth. The tooth surfaces of the helical teeth of the worm gear are designed to comprise the flat tooth surfaces and the arc tooth surfaces distributed on the two sides of the flat tooth surfaces in the tooth direction, the clamping stagnation phenomenon is avoided through the flat tooth surfaces under the low-load working condition, the contact stress is reduced through joint work of the arc tooth surfaces and the flat tooth surfaces under the high-load working condition, and therefore the meshing and transmission performance of the worm gear is improved; and the service life of the worm gear is prolonged.
本发明涉及蜗轮蜗杆传动技术领域,提供蜗轮、加工方法和相关设备。蜗轮包括轮体和分布于所述轮体的外周壁的轮齿,其中,所述轮齿为斜齿,所述轮齿的齿面包括平齿面和沿所述轮齿的齿向分布在所述平齿面的两侧的弧齿面。本发明将蜗轮的斜齿的齿面设计为包括平齿面和沿齿向分布在平齿面的两侧的弧齿面,实现低负载工况下利用平齿面避免卡滞现象,高负载工况下通过弧齿面与平齿面共同工作减小接触应力,从而提升蜗轮的啮合和传动性能,并提高蜗轮的使用寿命。
