Abstract

A bucket-wheel excavator has a frame provided with an unsplit-ring bearing that defines an axis for a shaft assembly. This assembly is formed by a solid core shaft extending along the axis through the bearing, an input-side tube shaft fitted over the core shaft to one side of the bearing and having one end turned away from the bearing and formed with an input flange, and an output-side tube shaft fitted over the core shaft to the opposite side of the bearing and having one end also turned away from the bearing and formed with an output flange. The opposite ends of these tube shafts are provided with angularly interengaging formations that rotationally couple them together and bolts press these formations axially into tight engagement with one another. A bucket wheel is carried on the output flange and a drive motor is connected to the input flange for rotating the shaft assembly and bucket wheel about the axis.
