Tooth surface design and manufacture for arcuate tooth trace face-gear

提出了一种新型弧线齿面齿轮传动及其加工方法,比直/斜齿形的面齿轮副具有更为优越的传动性能.弧线齿面齿轮传动是一种交错轴弧形齿圆柱齿轮与弧线齿面齿轮相啮合的传动.基于啮合理论,研究了弧线齿面齿轮副的切削理论以及相应的齿面设计、制造方法;建立了弧线齿面齿轮的加工模型,推导了弧线齿面齿轮的齿面方程,并建立了相应的有限元模型及三维仿真模型.提出了利用常规的格里森刀盘,在国内已有的数控加工中心或数控齿轮机床上加工弧线齿面齿轮的方法,制造工艺简单.

A new type of face-gear drive with intersected axes of rotation formed by an arcuate tooth trace face-gear and an arcuate tooth trace cylindrical pinion was proposed, which has better meshing performance than the helical and spur involute face-gear drives. An arcuate tooth trace spiral bevel face-gear drive used for transformation of rotation between intersected axes that was consisted of a spiral bevel face-gear and an arcuate tooth trace cylindrical pinion. By applying space engagement theory, the author developed the cutting princi- ple, mathematical model of design and machining for arcuate tooth trace face-gear. The equations of tooth surface of arcuate tooth trace face-gear was deduced and a 3-D model of FEM（finite element method） was established for further analysis. Based on the analysis of the machining method, it is convenient to generating the tooth surface of arcuate tooth trace face-gear by using the common Gleason cutter head with the general multi-axle numerical control machine tool.
