Working conditions of HWWT envelope reducer:
The staggered angle of the input and output shafts is 90℃; the worm speed does not exceed 1500r/min; the sliding speed of the worm's intermediate plane indexing circle does not exceed 16m/s; the worm shaft can rotate in forward and reverse directions;
The working environment temperature is -40℃~40℃.When the working environment temperature is lower than 0°C, the lubricating oil must be heated to above 0°C before starting, or lubricating oil with a low freezing point must be used; when it is higher than 40°C, cooling measures must be taken.
Model and mark of HWWT envelope reducer:
(1) HWT type-worm is cast on the worm wheel, the body and the cover are straight-profile toroidal worm reducer.
(2) HWWT type-the worm is welded on the worm wheel to weld the body and the cover of the straight profile toroidal worm reducer.
(3) HWB type-the worm is casted under the worm wheel, the body and the cover are straight-profile toroidal worm reducer.
(4) HWWB type-the worm is welded under the worm wheel to weld the body and the cover of the straight profile toroidal worm reducer.
