for the bucket wheel drive in excavators The planetary bevel KPB transmission gear is especially designed for drive systems of bucket-wheel excavators used in open-pit mining. The gearbox is the perfect solution for newly designed excavators. However, it can also be employed to upgrade already existing bucket-wheel drives. The KPB 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 transmission gear 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 fluid coupling and the jointed shaft transmit the drive from the electric motor to the gearbox input shaft. From there, the single bevel stage and the two planetary stages transmit it to the output shaft, which is connected to the bucket wheel shaft by the clamping ring. The bevel stage is equipped with a Klingelnberg toothing and has been case-hardened and machined according to the HPG method. MAAG GEAR

Gearbox description The two planetary stages consist of spur gears. The rims with internal toothing are part of 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 transmission gear casing is a sturdy, welded construction. It consists of the bevel stage casing, two rims with internal toothing, a connector of both rims and an...
