车削齿轮是圆柱齿轮加工中一种新的高效加工方法。本文从车齿原理，论述了采用直齿插齿刀车削齿轮，较国外常用的斜齿刀车削齿轮，有更高的理论造形精度。并以实例计算了在带切向刀架的滚齿机上车齿时的工艺调整方法，同时提出了设计车齿机床与设计滚齿机不同，必须注意其工艺特点，并列举了设计车齿机床的若干设计原则与建议。
Turning gears are a new and efficient method of machining cylindrical gears. In this paper, from the principle of the car’s tooth, the article discusses the use of a straight tooth gear cutter turning gear, compared with the commonly used foreign bevel gear turning gear, a higher theoretical accuracy. The method of adjusting the process of the gear on the gear hobbing machine with tangential tool rest is given by example. At the same time, the design of the gear cutting machine is different from the design of the gear hobbing machine, so we must pay attention to its process characteristics and enumerate some design of the gear cutting machine Principles and recommendations.
