齿圈支座是拖拉机上的一个关键零件 ,其外部齿形为直齿渐开线圆柱齿形 ,采用专用滚刀加工。齿圈支座齿形的主要参数为 :模数ｍ =3 2 5ｍｍ ,齿数ｚ=6 2 ,齿形角α =2 0° ,大径ｄｅ=2 13ｍｍ ,小径ｄｉ=2 0 5ｍｍ ,分圆直径ｄ =2 0 1 5ｍｍ。齿圈支座齿形的特点是其分圆直径小
Ring gear support is a key part of the tractor, the external tooth profile involute involute cylindrical tooth profile, the use of special hob processing. Ring gear support tooth profile of the main parameters: modulus m = 3 2 5mm, the number of teeth z = 6 2, the tooth angle α = 20 °, large diameter de = 2 13mm, diameter di = 2 0 5mm, sub-round Diameter d = 2 0 1 5mm. Gear ring bearing tooth shape is characterized by its small circle diameter
