Band tensioning reel component group with plastics deformation of outer machine part upon forming pressure coupling securing it to outer surface of inner machine part

摘要

The component group (1) has an outer machine part in the form of a steel disc (3) with its inner surface secured to the outer surface of an inner machine part, in the form of a roller bearing ring (2), via a pressure coupling. The overlap between the steel disc and the bearing ring, the size of the machine parts and their materials are selected for obtaining plastics deformation of the outer machine part upon formation of the pressure coupling.
