Disc angle teeth, called differential driving teeth and driven teeth, are divided into driving teeth and driven teeth as a group.
Working principle:
Single-stage reducer is a driving bevel gear (commonly known as angle tooth) and a driven bevel gear connected with the transmission shaft from the angle tooth of the basin, which rotates clockwise, sticks to its right side from the angle tooth of the basin, and the meshing point rotates downward, which is consistent with the forward direction of the wheel. Because the driving bevel gear has a small diameter and the driven angle tooth has a large diameter, it plays a role in reducing speed.
The two-stage reducer has an intermediate transition gear, the left side of the driving bevel gear is meshed with the umbrella tooth part of the intermediate gear, the basin angle gear is coaxial with a small-diameter spur gear, and the spur gear is meshed with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There are two deceleration stages in the middle. In the past, two-stage deceleration was mainly used for matching vehicles with low engine power, because it increased the volume of the shaft, and now it is mainly used for low-speed and high-torque construction machinery.
