(1) The accuracy of oil seal, spigot, steel ring is 1/3 higher than that of the market wheel reducer. For example, the tolerance of Fukai oil seal is 0 ~ 8 wires, and the tolerance of ordinary wheel reducer is 0 ~ 15 wires.
(2) The disk surface is drilled through the reamer, and the position of the tire hole is checked with the inspection tool disk to ensure the consistency of the hole diameter and the perfection of concentricity.
(3) In order to prevent the possibility of oil leakage of 1/10000, the machining center adopts the processing technology of rough boring and fine boring for the shaft hole; The 10 threaded holes at the bottom of the wheel hub reducer housing are all blind holes (most of the wheel hub reducer housing on the market are through holes).
(4) When drilling the legs of the wheel rim planet carrier, in order to prevent the angle from being slanted when the hole is deep, which may reduce the service life of the planet carrier after assembling the wheel rim assembly, the wheel hub reducer housing of Fukai brand is drilled and positioned 2.5mm in the machining center first, and then the vertical drilling is completed (most brands of planet carriers are made directly at one time).
(5) After the wheel rim is formed, it will be polished one by one with metallographic instrument, and then inspect each product on delivery to ensure the stability of the material of each product.
(6) The gear, planetary shaft, planetary gasket, needle roller bearing, stabilizing pin and wheel edge screw equipped with the wheel reducer assembly are the original products, with fine appearance and reliable quality.
(7) Steyr wheel reducer assembly is improved from the original bearing type to the needle roller type to prevent damage to the wheel reducer assembly caused by the wear of the bearing frame, and greatly improve the service life of the wheel reducer assembly.
(8) Fukai brand wheel reducer assembly is equipped with repair kits required for maintenance (including circlips, adjusting gaskets, wheel oil plugs, sun gear gaskets, gloves, etc.)
The wheel reducer is mainly composed of sun gear, planetary gear, ring gear and planetary gear carrier. Generally, the sun gear of the driving part is connected with the half shaft, the planetary gear carrier of the passive part is connected with the wheel, and the ring gear is connected with the axle housing. The wheel reducer is used to increase the driving force matching of the car to meet or modify the force of the entire transmission system. At present, the wheel reducer is a set of gear transmission device with speed reduction and torque increase to meet the matching needs of the whole transmission system. The power is transmitted from the engine to the main reducer of the front and rear axle through the clutch, transmission and transfer case, and then from the output end of the main reducer to the wheel reducer and wheels to drive the vehicle. In this process, the working principle of the wheel reducer is to transfer the speed and torque transmitted by the main reducer to the wheels after its speed reduction and torque increase, so the wheels can generate a large driving force under the reaction of ground adhesion. Thus, the stress of each part in front of the wheel reducer is reduced.
