本文从齿轮不是刚体而是弹性体的角度出发,分析齿轮的弹性变形。根据高速重载齿轮工作特点,具体分析弹性变形造成的危害。认为高速齿轮的设计特点,高精度是基本的和主要的,齿轮的修整是必要的。越是大功率传动,越需要修整。没有合适的修整,更高精度便成为实际上不可能。本文具体分析螺旋线修整的规律,引出设计计算方法。综合考虑大小齿轮的弹性变形。本计算方法考虑因素比所见到的资料详尽,结论更普遍。尤其是可以得出变形沿齿长的分布规律,从而可以据此进行设计计算。弹性变形的考虑只是高速齿轮设计中要考虑的一个重要方面,完善的设计方法仍应计及诸如热变形等其他方面,但在线速度100公尺/秒以下,弹性变形的考虑已足够。对于重载齿轮,本文的观点和方法也是可取的。
In this paper, the gear is not a rigid but elastomeric point of view, analysis of gear elastic deformation. According to the characteristics of high-speed heavy-duty gear operation, the specific analysis of the hazards caused by elastic deformation. Think high-speed gear design features, high precision is basic and the main, gear dressing is necessary. The more high-power transmission, the more you need to trim. Without proper dressing, higher precision becomes virtually impossible. This article analyzes the rules of helix trimming in detail and leads to the design calculation method. Consider the size of the elastic deformation of gears. The calculation method considerations are more exhaustive than the data you see, and the conclusions are more general. In particular, the distribution of deformation along the tooth length can be derived, so that design calculations can be made accordingly. The consideration of elastic deformation is only an important aspect to be considered in the design of high-speed gears. The perfect design method should still take into account other aspects such as thermal deformation. However, the consideration of elastic deformation is sufficient at the linear velocity of 100 m / s. For heavy-duty gears, this article’s point of view and methods are also desirable.
