在初始状态下,齿轮副的接触斑点如何,这个问题与齿轮传动工作平稳性和使用寿命有着密切的联系。特别是重载齿轮传动,常发现由于初始接触不良,导致齿面早期点蚀、剥落甚至失效。因此,接触斑点是评定齿轮副加工、安装误差的综合项目之一,尤其是低速中载和重载的齿轮传动。近年来随着硬齿面齿轮在重载齿轮传动中的广泛应用,保证齿面的接触精度更加重要。因为它不像软齿面,经跑合接触斑点有所增加,而是接触斑点基本上 In the initial state, the gear of the contact spots how the problem with the work of gear transmission stability and service life are closely linked. Especially heavy-duty gear drive, often found that due to poor initial contact, causing tooth pitting early, spalling or even failure. Therefore, the contact spot is to assess the gear processing, installation of one of the errors, especially in low-speed and heavy load gear. In recent years, with the hardened gear in heavy-duty gear transmission in a wide range of applications, to ensure the contact surface accuracy is more important. Because it does not like the soft tooth surface, the contact point by running the contact has increased, but the contact spots basically
