Description

Self-loosening of threaded fasteners under transverse vibration has been investigated by G. H. Junker, and the testing of locking performance by this method is being of the world's attention.<BR>The Junker's display of the locking performance is based on the relation between the input energy obtained as the product of external force by vibrating displacement and the residual fastening force.<BR>In this paper, another style of display, that is, relation between the loss of the fastening force per vibrating cycle in the specified fastening force and the full amplitude of vibrating displacement, is proposed.<BR>By this method, effects of different pitches, lubricants, running speeds, tolerance classes and fastening forces are examined, and the locking performances of a cylindrical washer, a nylon-ring insert locknut, locking by a pair of regular nuts, a spring washer, a conical spring washer and anaerobic locking compound are evaluated.
