摘　　要：滚齿加工技术在外齿轮的制造中占据重要地位,它是将运动学和刀具轮廓修正技术相结合的一项技术。齿轮加工前,尽管刀具轮廓的初始配置是由相关标准规定好的,但在实际操作中常常需要改变刀具轮廓以满足齿轮对强度和接触比的要求。用这些已修正轮廓的刀具加工出的齿轮,其几何形状和磨损特征会相应改变。现常用的修正轮廓刀具加工技术基于操作人员的经验所定,没有系统的标准和依据。本文总结了刀具轮廓对磨损机制的影响,结合各种不同的刀具轮廓和齿轮几何形状在加工中进行了测试。Gear hobbing plays a key role in the external gear production and a combination of kinesiology and the hob profile conditioning technology.Although the initial position of the hob profile is defined in relevant standards,it’s necessary to change the hob profile to address the gear’s strength and contact ratio requirements.With the hob whose profile has been conditioned,the resulted gears undergo changes in geometry and wear features.Currently,the common hob profile conditioning technologies are dependent upon the operator’s experience,and there are systematic standards and references.The paper summarized the effect of hob profile on the wear mechanism and carried out tests during the production with various hob profiles and gear geometries.
