用圆盘拉刀拉削齿轮的方法,在机械制造业中获得广泛地应用。用圆拉法加工出的直齿锥齿轮,在本身的啮合精度、工作平稳性和噪音方面,在轮齿的强度和耐磨性方面,都不比用传统的铣刨等加工方法所加工的齿轮差,在某些方面甚至更好,特别是圆拉法的生产率之高,是其它加工方法所不能相比的。另外,由于切齿过程的特点,使圆拉机床的结构比其它类型加工直齿锥齿轮机床大为简化。但是,圆拉法加工直齿锥轮所用的圆盘拉刀,结构复杂,制造困难。
The method of pulling a gear with a circular broach has been widely used in the machinery manufacturing industry. Straight bevel gears machined by the round-pull method have no difference in the strength and wear resistance of the teeth in their meshing accuracy, workability and noise, as compared with gears machined by conventional milling or the like Poor, and in some ways even better, especially the high productivity of the circular method, which can not be compared with other processing methods. In addition, due to the characteristics of the cutting process, so that the structure of the circular pull machine than other types of processing straight bevel gear machine greatly simplified. However, the round broach used in the machining of straight bevel gears is complicated in structure and difficult to manufacture.
