准双曲面齿轮热处理畸变及接触区影响研究
|
摘要
准双曲面齿轮作为主减速器的重要零部件之一,其齿廓的畸变程度直接影响着齿面误差和齿轮接触区质量及一致性的好坏。针对齿轮热处理变形不受控的问题,研究了齿轮热处理的畸变机理。应用45点拓扑网格误差分析接触区偏移规律,以专用锥齿轮检测设备Gleason GMM350和600HTT滚检机为载体,通过实验对比齿轮热处理前后齿面精度变化和接触印痕偏移规律,验证了接触区偏移理论分析结果的正确性,且实验表明,齿轮热处理接触区从大端稍偏齿顶位置向齿面中间移动。
Hypoid gear is one of the important parts of the main reducer,its degree of tooth profile distortion directly affects the tooth surface error and the quality and consistency of the gear contact area. In order to solve the problem of uncontrolled heat treatment of gears,the distortion mechanism of gear heat treatment is studied. The 45-point topology grid error is used to analyze the law of contact zone offset. Using the special bevel gear detection equipment Gleason GMM350 and 600 HTT roller inspection machine as the carrier,by comparing the variation of the tooth surface accuracy and the offset of the contact mark before and after the heat treatment of the gear,the correctness of the theoretical analysis result of the contact zone shift is verified. The correctness of the contact zone offset theory,and experiments show that the gear heat treatment contact zone moves from the large end slightly to the tooth tip position to the middle of the tooth face.
