Abstract
The invention concerns a rolling unit for machining the wheel running surfaces of wheelsets for rail vehicles, with the rolling unit featuring at least one work roller by means of which the wheel running surface to be machined is subjected to a deep rolling process following manufacture of the wheelset in new condition or, at a later date, after reprofiling to increase the service life of the wheel running surfaces. The task is solved to create a relevant rolling unit by means of which the wheel running surfaces can be deep-rolled in the forward feed process using work rollers. This task is solved by the rolling unit featuring a base body on which a support arm is located in a vertical position to the base area, on which a receptacle is supported that is unilaterally fixed in position via a thread in the support arm and on which an angular contact ball bearing is located; this supports at least one work roller featuring at least two different rolling radii.
