Technical description

Observe the instructions in section 3, "Safety instructions"!

5.1

General description

The gear unit is supplied as a two or threestage helicalgear 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 exact design and the corresponding direction of rotation of the gear unit can be found in the drawings
in the gearunit documentation.

The gear unit can be operated in both directions of rotation.

The gear unit is characterised by a low noise level, which is achieved by helical gears with a high contact
ratio and a sounddamping housing.

The good temperature characteristics of the gear unit are achieved by its high degree of efficiency and its
large housing surface area.

The gear unit must be supplied with oil by an addon or external oilsupply system.

5.2

Housing

The housing is in two sections and made of cast iron; if required, it may also be 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 inspection)

•

Oilsight glass or angular oillevel indicator (for checking the oil level)

•

Oildrain plug and/or oildrain cock (to drain the oil)

•

Air filter (for venting)

Colour codes for ventilating, oil inlet, oil level and oil drainage:

Airrelief point: yellow

Oildraining point:

white

Oilfilling point: yellow

Lubrication point:

red

Oil level:

red
