直齿锥齿轮被广泛用于交叉轴之间传递动力的齿轮机构中。锥齿轮的制造误差、热处理变形造成的齿向误差、轴交角误差以及轴向位置误差等,都将会影响齿面的接触精度。为了减少以上因素对齿面接触精度的影响,提出了直齿锥齿轮的鼓形齿加工。 本文介绍的鼓形齿的加工方法,是用 Y 23 Spur bevel gears are widely used in gear mechanisms that transmit power between cross shafts. Bevel gear manufacturing errors, heat treatment deformation caused by the tooth direction error, shaft angular error and axial position error, will affect the tooth surface contact accuracy. In order to reduce the influence of the above factors on the contact accuracy of the tooth surface, a drum tooth machining of a straight bevel gear is proposed. This article describes the drum gear processing method is to use Y 23
