Extreme High Overhung Loads

  • Rigid dedicated Hansen P4 housing design to ensure smooth transition of high forces from the centre bore to the mounting feet, which are positioned concentric to the low speed shaft.
  • Possibility for extended bearing housing integrated in the housing casting and a wide range of robust bearing arrangements provides extremely high thrust load and bending moment capacity.

Oil-tight drywell

The standard integrated drywell prevents oil from leaking along the low speed shaft at any circumstances.

Document Type

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.

Backstops are safety devices and have to be inspected at regular time intervals.  The periodical inspection is to be carried out by authorized personnel.  The frequency of the inspection depends on the type of application.  Please refer to the P4 service manual for recommended inspection intervals
