摘　　要： 介绍了一种新型的螺旋锥齿轮—对数螺旋锥齿轮,该齿轮成功地将对数螺旋线应用为螺旋锥齿轮的齿向线,可以实现等螺旋角啮合。齿轮受载后的齿面接触区是衡量齿轮接触性能和传动质量的一个重要指标,将直接影响到齿面磨损及其使用寿命。采用有限元软件ABAQUS对对数螺旋锥齿轮进行动态接触分析,分析对数螺旋锥齿轮承受轻载和重载后的齿面接触区的形态及其变化规律,并与对滚实验的结果进行对比。得出对数螺旋锥齿轮的接触区承载后呈不规则椭圆形位于齿面中间偏小端,且随着载荷增大接触区在长度和宽度方向都有所增大。 It introduced a new type of bevel gears--logarithm spiral bevel gear, applied the logarithmic spiral line for the spiral bevel gear tooth successfully, which can achieve helix angle of engagement. The gear contact area under load is an important indicator to measure the gear contact performance and drive quality, which will affect the tooth surface abrasion and its service life directly. It used the finite element software ABAQUS to make the dynamic contact analysis of logarithmic spiral bevel gear, to analyze the tooth cantact form and its change rule of logarithmic spiral bevel gear under the light load and overload, and comparing with the results of the rolling experiment. The contact area of the logarithmic spiral bevel gear under load was irregular oval, and it located in the middle of the small end of the tooth surface, as the load increased, the contact area was also increased in length and width directions.
