Relative rotary angle adjustment of IC engine control shaft - involves shaft carrying in end area rotary angle-movable, centred and axially secured drive wheel

摘要

A radial flange (8) for axial securement of a hub (10) concentrically located in the shaft end area (5) is in non-rotary connection with the drive wheel (4). The assembly (14) comprising the drive wheel (4) and the hub (10) via an axially acting tension device (15 spring 16) is movable under friction to a stop (17,21) in the end area (5) of the control shaft (2). Between a hub-side section (19) of the radial flange (8) of the hub (10) and a free face surface (20) of the shaft end area (5) a plate spring (16) is tensioned. The free face surface (20) of the shaft end area (15) acts as an additional stop (21) for a friction ring (22). USE/ADVANTAGE - To eliminate noise in the drive mechanism of an IC engine.
