圆弧齿轮传动自1958年公开发表以来,由于其优异的传动能力,为许多国家所重视并得到推广应用。在我国,也已在机械,冶金,石油、电力、化工、起重等许多行业的减速及增速传动中广泛使用,也取得很大效益,这些都表明它是一种很有前途的传动形式。但是由于这种传动不具有渐开线齿轮所具有的中心距可分性,为保证轮齿间的正确啮合位置,需要提高齿轮及箱体某些尺寸的加工精确度。若误差过大, Arc gear transmission since its publication in 1958, due to its excellent transmission capacity, valued by many countries and has been widely used. In our country, it has also been widely used in the deceleration and growth drive of many industries such as machinery, metallurgy, petroleum, electricity, chemical industry, lifting, etc., and has also achieved great benefits. All these show that it is a promising form of transmission . However, since this type of transmission does not have the center-to-center separability of the involute gear, in order to ensure the correct meshing position of the gear teeth, it is necessary to improve the machining accuracy of some dimensions of the gear and the case. If the error is too large,
