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.
