ABSTRACT:
The invention relates to a spur-gear system for driving a roll shell which bears an outer gear-wheel on one of its ends. The roll shell and the outer gear-wheel are monted via a common self-aligning bearing which is disposed concentrically within the outer gear-wheel. A pinion gear-wheel meshing with the outer gear-wheel is also mounted via a self-aligning bearing disposed concentrically within it. Both self-aligning bearings are mounted on the same support in the form of a cap. The outer gear-wheel and the pinion gear-wheel each have an abutment rim on one side. The contact surfaces thereof roll against each other during normal operation so that the axes of the two gear-wheels are parallel with each other. A geared coupling shaft driving the pinion gear-wheel is inclined in such a way that the pitching moment acting on the pinion keeps the two abutment rims in contact with each other.
