Ч2-160 (Ч2-80/160) (CH2-160 (CH2-80/160))

Design features

The worm two-stage reducer is unified with the worm single-stage universal reducers CH-80 (high-speed stage) and CH-160 (low-speed stage)

Application area

Designed to increase torque and reduce speed

Note:
The torque and efficiency indicators are given at a value of PVC = 1500ob / min., t°C of the environment is + 20°C (use of alloyed oils). If unalloyed oils are used, these values should be reduced by 14%

Conditions of application of the gear units CH2-160:

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.
