<p><P>PROBLEM TO BE SOLVED: To satisfy both of the securement of sufficient torque transmission force and the securement of vibration control performance of a vibration control bush for a rotary shaft and to enhance flexibility of setting a linear characteristic region of an elastomer performed by a stopper. <P>SOLUTION: The vibration control bush for a rotary shaft includes: an outer sleeve 1; an inner sleeve 2 which is arranged in and concentrically with the inner circumference of the outer sleeve and is fixed to a power transmission member of the inner circumferential side; an outer circumferential elastomer 3 which is made of rubbery elastic material, is joined integrally to the outer circumferential surface of the outer sleeve 1 and is forced into the inner circumference of a power transmission member of the outer circumferential side; an inner circumferential elastomer which is made of rubbery elastic material and is joined integrally to both of the inner circumferential surface of the outer sleeve 1 and the outer circumferential surface of the inner sleeve 2; and the stopper 5 composed of a plurality of first protrusions 11 which are formed on the inner circumferential surface of the outer sleeve 1 at a prescribed interval in the circumferential direction and a plurality of second protrusions 21 which are formed on the outer circumferential surface of the inner sleeve 2 at a prescribed interval in the circumferential direction and are located between respective first protrusions 11. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
