Title:
SLIPPINGGOFF PREVENTIVE DEVICE OF SNAP RING
Document Type and Number:
Japanese Patent JPS54123643
Kind Code:
A
Abstract:
PURPOSE:To prevent the slipping-off of a snap ring mounted to the outside of a body of revolution by centrifugal force in the case when the body of revolution turns by simple constitution. CONSTITUTION:A rotary portion material 2 such as a toothed wheel is fitted to the outside of a body of revolution 1 such as a pivot, the motion of the rotary portion material 2 in the one direction of the axis direction of rotation is regulated by means of a stage portion 1a of an outer circumference of the body of revolution 2 and the movement in the other direction is controlled by means of a snap ring 3 inserted into a circumferential groove 1b of an outer circumference of the body of revolution 1. A plurality of holes 2a in the axis direction of rotation, which inlets are let face to the snap ring 3, are installed to the rotary portion material 2, and projecting pieces 4a that house sliding pieces 4 and springs 5, which act so as to push the sliding piece outside the holes 2a, and move on an outer circumference of the snap ring 3 at the outer ends of the sliding pieces 4 are each mounted to each hole 2a. Thus, the sliding pieces 4 are pushed out by means of the springs 5, the projecting pieces 4a advance on the outer circumference of the snap ring 3 and the snap ring 3 cannot expand.
