Description of the gearbox
The gearbox is a single- or multi-stage low-backlash gearbox. Certain product types may be used
only in a defined mounting position.
Various types of motors can be accommodated using an adapter plate and, where necessary, a
bushing.
The gearbox is equipped with an integrated linear length compensation to compensate for the
expansion of the motor shaft when heated up.
The gearbox can be used in the potentially explosive atmospheres defined in Chapter 3.4 "Ex
model".
