General description

The helical gear unit is supplied as a one­, two­, three­ or four­stage gear unit. The bevel­helical gear unit
is supplied as a two­, three­ or four­stage 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.
As a principle, the gear unit can be operated in both directions of rotation. The only
exceptions are gear types with backstop or overrunning clutch. If rotation reversal is
required for these types of unit, Siemens should be consulted.
A number of shaft configurations (types and rotation directions) are possible. These are shown in the
following table as solid shafts:

When mounting the auxiliary drive (as maintenance and/or load drive) the assignment of the
direction of rotation to the design is defined in the dimensioned drawing.
The gear units are characterised by a low noise level. This is achieved by helical and bevel­helical 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.
