Abstract
Abstract A self-aligning mounting device, particularly for the attachment of hydraulic or pneumatic cylinders or piston rods, comprising a mounting lug, a bushing fitted in the lug and a shaft journalled in said bushing. The circumference of at least a central portion of the bushing consists of a material having a high surface hardness and is bearing under a certain play against a surrounding ring-shaped rib consisting of non-elastic material and projecting from the inner surface of the mounting lug, the edges of said rib being deformable by plastic deformation under the influence of a load acting upon the mounting device when mounted with the shaft in a tilted position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
A self-aligning mounting device, particularly for hydraulic or pneumatic cylinders or piston rods, comprising a mounting lug, a bushing fitted in the lug and a shaft journalled in said bushing, wherein the circumference of a central portion of the bushing, which central portion consists of a high surface hardness material, is bearing against a surrounding ring-shaped rib projecting from the inner surface of the mounting lug, said rib consisting of a substantially non-elastic material having less hardness than the material of the central portion of the bushing and presenting an intentionally adapted small radial play with respect to said bushing.
Claim 2
Dependent Claim
100 words
A self-aligning mounting device, particularly for hydraulic or pneumatic cylinders or piston rods, comprising a mounting lug, a bushing fitted in the lug and a shaft journalled in said bushing, wherein the circumference of a central portion of the bushing, which central portion consists of a high surface hardness material, is bearing against a surrounding ring-shaped rib projecting from the inner surface of the mounting lug, said rib consisting of a substantially non-elastic material having less hardness than the material of the central portion of the bushing and presenting an intentionally adapted small radial play with respect to said bushing.
Claim 3
Dependent Claim
36 words
A mounting device as claimed in claim 1, characterized in that the inner surface of the end portions of the bushing are provided with each an annular Rib, in which ribs the shaft is rotatably journalled.
Claim 4
Dependent Claim
34 words
A mounting device as claimed in claim 1, characterized in that the bushing consists of a hardened sleeve in which a self-lubricating bearing bushing is fixedly mounted at each end portion of the sleeve.
