Pan angle teeth, also known as differential active and passive teeth, are composed of two parts: main teeth and passive teeth. They are commonly referred to as disc angle teeth or bevel gears and are the core transmission components of the axle differential. According to the type of reducer, it can be divided into single-stage, two-stage, and wheel side reducers: single-stage reducers are achieved by meshing the active bevel gear with the bevel gear, and the diameter of the active gear is smaller than that of the bevel gear; The two-stage type is equipped with an intermediate transition gear to form a two-stage reduction, which has been used in low-speed and high torque construction machinery; The wheel reducer places the second stage of deceleration near the wheels and uses a planetary gear or cylindrical gear pair structure to reduce the half shaft torque and adjust the wheel axis position.
