ABSTRACT:
A cylindrical gear unit which includes a gear housing, a gear pinion and a gear wheel, the gear pinion being fixed to a shaft which is rotatably journalled in bearings supported by at least one bearing support. One of the bearing supports comprises a sleeve in which a roller bearing is fixedly mounted, a fixing plate supported by the gear housing, as well as a disc-shaped rib portion which interconnects the sleeve and the fixing plate. The rib portion extends substantially along the entire length of the sleeve and the fixing plate and is substantially parallel to a tangential plane on the contact line between the gear pinion and the gear wheel. In addition, at least one stop face for the sleeve is arranged at a small distance from the outside of the sleeve on at least that side of the sleeve facing away from the gear wheel.
