There are two types of automobile reducer commonly used, single-stage and double-stage, which are arranged horizontally or vertically on the axle housing. The automobile reducer housing with two drive axles has two types: through and non-through. The through-type reducer shell is divided into two types: single through and double through. The reducer housing of some segmented axle housings is integrated with the middle section of the axle housing.
Heavy-duty trucks and mining dump trucks are required to have a larger reduction ratio and a larger ground clearance in order to adapt to multiple uses and complex road conditions. The heavy-duty vehicles produced by some foreign automobile manufacturers use planetary gear wheel reducers and bevel gear planetary wheel reducers. The advantage of this wheel-side reducer structure is that it has a smaller outline size to obtain a larger speed ratio, and it can be arranged inside the wheel. The materials of foreign reducer shells are gray cast iron, ductile iron, malleable cast iron and aluminum alloy.
A digital programmable controller is used on both automatic lines, and a rotary power head is used to adapt to the hole processing of various reducer shells and covers at different positions. An automatic inspection and compensation device is also set on the inner hole station of the fine wok.
In the multi-segment automatic line processing, the boss plane of the bearing cover is milled first, and then the second connecting surface of the reducer shell is processed. This plane is used as the positioning reference to process the flange end surface and outer circle, stir the bearing hole, and mill the inner end surface. , Drilling and tapping bearing cap bolt holes, drilling oblique oil holes, cutting internal threads, etc., clean and inspect after *. After installing the bearing cover, machine the earring hole and the oil injection hole from the rough, semi-finished, and refined shaft tube mounting holes at both ends. *After finishing the two pairs of bearing holes and the inner end faces of the driving bevel gear and differential assembly.
