5.1
General description
The gear unit described is a gear unit developed for driving machines in general engineering applications.
The gear unit is supplied as a single, two, three, four, five or sixstage helical or bevelhelical gear unit.
It is designed for installation in the horizontal mounting position. If necessary, it can also be designed for
installation in a different position.
The gear unit can be operated in both directions of rotation. However, it is possible that
a certain direction of rotation has been specified in the order which is realised by
addingon a backstop or overrunning clutch.
The gear unit is characterised by a low noise level. This is achieved by ground bevel and cylindrical gears
with a high contact ratio and special sounddamping housings.
The good temperature characteristics of the gear unit are achieved by its high degree of efficiency, large
housing surface and performancerelated cooling system.
If required, standardrange gear units can be fitted with a motor bell housing, motor swing base, torque
reaction arm, oil cooler and backstop.
5.2
Housing
The housing is made of cast iron in two parts; if necessary, it may also be made of steel.
The housing is rigid in design and due to its form has excellent noise and temperature characteristics.
The gearunit housing comes with the following equipment:
•
Lifting eyes or transport lugs (adequately dimensioned for transport)
•
Inspection and/or assembly cover (for oil filling and/or inspection)
•
Oil dipstick (to check the oil level)
•
Oildrain plug (for oil drain)
•
Breather screw (for venting)
