Self-excited vibration of a spring clutch

Research output: Contribution to journalArticle

Abstract

Self-excited vibration of a spring clutch used in an electrophotography fuser was investigated. From the results of theoretical and experimental investigations, the following points were deduced: (1) The vibration is basically induced by an asymmetric friction force due to asymmetric contact at a slipping surface. (2) Lissajous figures of the vibration were circular and the vibration was forward-whirling. (3) Calculated results based on the present model qualitatively agreed with experimental observations, and several methods of suppressing vibration were proposed. The spring clutch should be designed such that it has the following characteristics: (a) sufficient damping, (b) low friction coefficient, (c) sufficient gap during slipping period and perfect fastening during transferring torque, and (d) small initial spring static displacement. These measures have been used to overcome the abnormal vibration problem.
