Installation Notice for NMRV 050 Gearbox

  • The reducer should be mounted stably to avoid any vibration.
  • Before mounting, make sure the output shaft of the reducer will turn to the correct direction.
  • In case that the reducer has been in store so long as 4 to 6 months, check the seal first, as it may stick to the shaft caused by lacking lubricant or lose its flexibility. If necessary, change the seal.
  • For reduction units with hollow output shafts, please use the torque arms. If it is not possible make sure that the shaft is without axial load.
  • Whenever possible, protect the reducer from direct sunlight and any other bad weather.
  • Make sure good ventilating conditions.
  • In the case of ambient temperatures <-5°C or >+40°C, contact the technical department, please.
  • The various parts (pulleys, gear wheels, couplings, shafts, etc.) are mounted on solid or hollow shafts with a special screw thread that anyhow ensures correct operation without risking damage to the bearing or external parts of the units.
  • Painting must definitely not go over rubber parts or the holes on the breather plugs.
  • Checking the oil level.
  • Supposing gear units have not been coupled with motors, please pay attention to the following items to make sure the right connection. Mounting to B5, B14.
  • Checking whether the tolerance between shafts and motor flanges fits the essential standard.
  • Washing the dirt and the paint on the surface of the shafts, center bores and flanges.
  • Lubricating the surface to avoid corruption.
  • Starting must take place gradually, without immediately applying the maximum load.
  • Some proper precautionary measures should be taken as the objects or materials under motor drives can be easily damaged.
