新型齿形高速重载齿轮设计研究

渐开线齿轮传动是机械传动的主要传动方式,具有加工简单、中心距不灵敏等优点,但也有接触强度低、滑动系数大等明显缺点.文中基于分离函数法原理实现了一种新型齿形齿轮的设计,并进行了主要参数的计算和有限元强度仿真.结果表明,该齿轮比渐开线齿轮具有更大的承载能力,可满足高速重载齿轮传动的要求.

Study on the high speed and heavy duty gear with new typed tooth form

The involute gear transmission is the major transmission mode in mechanical transmission that possesses advantages of simplicity in machining and non-sensitive of center distance etc. , yet it has evident shortcomings in low contacting strength and large sliding coefficient etc.. On the basis of the principle of separation function method this paper achieved a kind of design of gear with new typed tooth form and carried out a calculation and finite element strength simulation on the main parameters. The result showed that this kind of gear possesses more load-bearing capacity than those of the involute gears, and could satisfy the requirements of high speed and heavy duty gear transmission.
