Bearing profile for drive shaft of cutter

摘要

The bearing casing (7), on its outer periphery (8), has longitudinally running support ribs (9), with which the bearing casing is held centrally in the protective tube. Each support rib comprises a radially directed rib (20) and a peripherally directed rib (30). The peripheral rib extends axially to the radial rib and connects to the end of the radial rib facing the protective tube (1). The radial rib ends before the inner periphery of the protective tube, whilst the peripheral rib supports on the inner periphery (16) of the protective tube. The peripheral rib connects at an angle (33) of approximately 90 degrees with the radial rib.
