Hansen P4 units use one of the following systems:

  • Splash Lubrication (standard with horizontal shaft gear units for speeds between 750 and 1800RPM at the high speed shaft.  Gears and output shaft bearings are lubricated by immersion in the oil bath.  Oil splash from gears fill the oil pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in the housing and covers.)
  • Force Feed Lubrication (all rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines.  Forced feed lubrication is available as circulation lubrication or pressure lubrication.

The P4 Single Stage gear units have been designed with an enlarged housing and an increased shaft height. The vast cooling surface raises the thermal rating and the larger oil sump assures a longer oil life. In combination with the service cover, a cooling coil can be fitted, without having to disassemble the complete gear unit.

The increased shaft height also results in the input shaft being better positioned versus the shaft height of the electric motor.

As such, motor and gear unit will be equally affected by thermal expansion and the static alignment is not disturbed during operation.
