由冠形齿轮和小齿轮组成的齿轮对及差动补偿传动装置
摘要：
本发明涉及一种由具有90度轴交角的冠形齿轮(1)和作为直齿圆柱齿轮的小齿轮(2)组成的齿轮对。根据本发明，为降低冠形齿轮(1)的齿(5)的根切，小齿轮(2)的齿(3)的压力角在相对于冠形齿轮(1)的径向方向上从外向内增加，或在恒定压力角的情况下小齿轮(2)的齿(3)的齿廓变位在相对于冠形齿轮(1)的径向方向上从外向内减小。
摘要（英）：

The present invention relates to a gear pair consisting of a crown gear (1) and of a pinion gear (2) provided in the form of a spur gear with an axis crossing angle of 90 DEG . According to the invention, the teeth (3) of the pinion gear (2), in order to reduce an undercut of the teeth (5) of the crown gear (1), have a pressure angle, which increases from the outside inward in a radial direction with regard to the crown gear (1), or in the event of a constant pressure angle, have a profile offset, which decreases from the outside inward in a radial direction with regard to the crown gear (1).
