Description

New type right angle reducer

technical field

The invention relates to the field of reducers, in particular to a novel right-angle reducer.

Background technique

The right-angle reducer refers to the model whose input shaft and output shaft intersect at an angle of 90°. In recent years, a large number of right-angle reducers have appeared in industrial production lines and many equipment imported from abroad. This is because right-angle reducers can make industrial production lines or some hosts more compact and occupy as little space as possible. The right-angle reducer technology comes from abroad, and the right-angle reducer adopts the two-stage reduction transmission mode of cylindrical involute gear and worm gear. In addition, there are structural forms of involute gears and bevel gears. The disadvantage of the first structure is that the high-speed gear transmission noise is relatively large, the low-speed worm gear transmission efficiency is low, and the temperature rises. If the low-speed stage is a toroidal worm transmission, the manufacturing process is complicated, and a special high-precision processing machine tool is required. And complex processing technology, which greatly increases the manufacturing cost; the disadvantage of the second structure is that it is noisy, assembly and processing are more troublesome, and its application is not as wide as the former.
