Reducer Worm
Two-stage
Ч2-80/125 (CH2-80/125)
Design features
The worm two-stage reducer is unified with the worm single-stage universal reducers CH-80 (high-speed stage) and CH-125 (low-speed stage)
Application area
Designed to increase torque and reduce speed

U — nominal gear ratio;
М — nominal torque on the output shaft,Нм;
Р — the design power of the gearbox on the output shaft, kW, is specified at a speed of 1500 rpm;
Conditions of application of the reducer:
- Load of any type within the maximum permissible value-it is allowed to give a load of both a constant and variable nature, directed both in one direction and changing the direction of its impact.
- Continuous use up to 24 hours a day.
- Rotation with a maximum frequency of up to 1800 rotations per minute in any direction.
- The maximum permitted concentration of dust in the atmosphere is up to 10mg per cubic meter.
- Various categories of accommodation and the possibility of application in moderate and hot humid or dry climates.
