Technical Data

The KPB transmission gear unit is the perfect solution for newly designed excavators. However, it can also be employed to upgrade already existing bucket-wheel drives. The KPB gear unit is installed between the electric motor and the bucket wheel shaft. The coupling connects the gearbox input shaft with the electric motor, while the output torque is transmitted to the bucket wheel shaft via the clamping ring. The KPB transmission gear unit is equipped with a monitoring system. It is also fitted with a lubrication system (without oil cooler) integrated into the gearbox casing. The gearbox casing also serves as oil tank.

Gearbox description
The two planetary stages consist of spur gears. The rims with internal toothing are in permanent contact with the casing. The planet carrier of the second planetary stage is also used as the output shaft, shaped as a bushing. The toothing of the sun pinions and of the planet wheels is case-hardened and ground, while the rims with internal toothing are tough-hardened. The gearbox rotors are positioned by the roller bearings. 

The casing of the KPB transmission gear unit is a sturdy, welded construction. It consists of the bevel stage casing, two rims with internal toothing, a connector of both rims and an output bearing housing. The torque lever is directly connected to the output bearing housing and to the connector of both rims with internal toothing.
