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.
