Shaft-hub-connection, particularly for fixing roller bearing in ball screw nut of electromechanical steering system of vehicle, has mounting ring, whose contact surfaces include angle in range of five degree to fifty degree with each other

摘要

The shaft-hub-connection has a component with an axial contact shoulder (110) and a circumferential groove (103) where another component is arranged at former component and retained at the axial contact shoulder. A mounting ring (104) retains at a flank (107) of the former component with a contact surface (114) and at latter component with another contact surface (115) to clamp the latter component with the axial contact shoulder of the former component. The contact surfaces of the mounting ring include an angle in the range of 5 degree to 50 degree with each other. Independent claims are included for the following: (1) a ball screw nut with a roller bearing, which has an inner ring; and (2) an electromechanical steering system with ball screw drive.
