Wheel Hub Speed Reducer Assembly for off-Highway Mine Truck

The wheel side reducer consists of a sun wheel and three small rowsStar double toothWheels, a torsion tube composition; It is a system with internal meshing and an external meshingNWPlanetary gear transmission reduction mechanism.

Structural features:
1.The sun wheel itself floats, one end of the sun wheel is connected by a spline and the motor shaft, and the other end is automatically positioned by meshing with three large planetary wheels evenly distributed along the circumference, while ensuring proper meshing backlash and tooth top clearance.
2.The three twin large planetary wheels are driven by the sun wheel, the twin planetary wheels are mounted on the bearings of the frame, and the internal teeth of the torque tube at the other end mesh, and the torsion tube is connected with the hub to form a whole, and then the two centripetal thrust bearings of the hub rotate around the frame.
3.The wheel hub provides the mounting surface for the tire. The design of the solar wheel shaft can float after being subjected to radial force to ensure the transmission accuracy of the planetary gear mechanism of the gearbox; When the sun axle of the planetary transmission gearbox is working, it floats to achieve the average load of the planetary transmission and prolong the service life of the gearbox.
