Abstract
Official abstract text for this publication.
A buffer stopper capable of increasing an absorbable energy amount without causing changes in characteristics due to wear of a buffer body. In order to achieve the object, the buffer body containing a rubber elastic body disposed between an end surface formed in a housing and an end surface formed in a shaft which is relatively movable in the axial direction with respect to the housing and a wear resistant sheet which is provided so as to surround the outer peripheral surface of the buffer body and which can contact an inner peripheral surface of the housing by expansion and deformation in the radial direction of the buffer body are provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A buffer stopper comprising: a buffer body containing a rubber elastic body disposed within a cylindrical recess formed in a housing, and between an end surface of the cylindrical recess formed in the housing and an end surface formed in a shaft which is relatively movable in an axial direction with respect to the housing, wherein the buffer body in an uncompressed state provides a uniform annular gap between an outer peripheral surface of the buffer body and an inner peripheral surface of the cylindrical recess throughout an entire axial length of the buffer body; a wear resistant sheet which is provided so as to entirely surround an outer peripheral surface of the buffer body and which can contact an inner peripheral surface of the housing by expansion and deformation in a radial direction of the buffer body, wherein the wear resistant sheet is operable to suppress expansion and deformation of the buffer body in the radial direction; and first and second metal rings, wherein a portion of the body is arranged between the rings and the wear resistance sheet. 2. The buffer stopper according to claim 1 , wherein the wear resistant sheet contains cloth having elasticity. 3. The buffer stopper according to claim 1 , wherein the first and second metal rings each have a flat washer shape, wherein the first and second metal rings are parallel to each other, and wherein the buffer body is bonded between the first and second metal rings. 4. A buffer stopper comprising: a buffer body containing a rubber elastic body disposed within a cylindrical recess formed in a housing, and between an end surface of the cylindrical recess formed in the housing and an end surface formed in a shaft which is relatively movable in an axial direction with respect to the housing, wherein the buffer body in an uncompressed state provides a uniform annular gap between an outer peripheral surface of the buffer body and an inner peripheral surface of the cylindrical recess throughout an entire axial length of the buffer body; a wear resistant sheet which is provided so as to entirely surround an outer peripheral surface of the buffer body and which can contact an inner peripheral surface of the housing by expansion and deformation in a radial direction of the buffer body, wherein the wear resistant sheet is operable to suppress expansion and deformation of the buffer body in the radial direction; and first and second metal rings, wherein the first and second metal rings each have a flat washer shape, wherein the first and second metal rings are parallel to each other, wherein the buffer body is bonded between the first and second metal rings, and wherein the first and second rings are in contact with the end surface of the cylindrical recess and the end surface of the shaft, respectively.
