Abstract
Abstract A locking and sealing device, especially for sealing between concentric surfaces while locking a bearing to at least one of the surfaces in which a ring element, preferably of metal, has a sealing element connected thereto with the ring element arranged for locking engagement with a cylindrical surface while the sealing ring sealingly engages the same surface and projects radially therefrom for sealing engagement with the other surface whereby a seal is established between the surfaces while a bearing engaging the cylindrical surface is locked in place by the ring element.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
197 words
A locking and sealing device for locking and sealing a bearing having an outer ring engaging a cylindrical surface forming an axial bore through a housing, an inner ring engaging a cylindrical surface of a shaft extending through said bore and anti-friction elements disposed between said inner and outer rings, comprising, in combination, a collapsible-expansible metal ring element having a peripheral surface engaging one of said cylindrical surfaces adjacent one of said inner and outer rings and having a radial face engaging an end surface of that ring engaging said one of said cylindrical surfaces for locking said bearing against displacement in one axial direction, and a sealing element of elastic rubber-like material bonded to said metal ring element remote from said peripheral surface and radial face, and in concentric relation to said metal ring and having a first annular portion sealingly engaging said one of said cylindrical surfaces adjacent said metal ring element at the opposite side from said radial face, and a second annular portion at a radial distance from said first annular portion sealingly engaging an end surface of the other of said inner and outer rings engaging the other of said cylindrical surfaces.
Claim 2
Dependent Claim
197 words
A locking and sealing device for locking and sealing a bearing having an outer ring engaging a cylindrical surface forming an axial bore through a housing, an inner ring engaging a cylindrical surface of a shaft extending through said bore and anti-friction elements disposed between said inner and outer rings, comprising, in combination, a collapsible-expansible metal ring element having a peripheral surface engaging one of said cylindrical surfaces adjacent one of said inner and outer rings and having a radial face engaging an end surface of that ring engaging said one of said cylindrical surfaces for locking said bearing against displacement in one axial direction, and a sealing element of elastic rubber-like material bonded to said metal ring element remote from said peripheral surface and radial face, and in concentric relation to said metal ring and having a first annular portion sealingly engaging said one of said cylindrical surfaces adjacent said metal ring element at the opposite side from said radial face, and a second annular portion at a radial distance from said first annular portion sealingly engaging an end surface of the other of said inner and outer rings engaging the other of said cylindrical surfaces.
Claim 3
Dependent Claim
20 words
A locking and sealing device according to claim 1, wherein said second annular portion sealingly engages the other cylindrical surface.
Claim 4
Dependent Claim
35 words
A locking and sealing device as claimed in claim 1, wherein said one of said cylindrical surfaces has an annular groove formed therein and said metal ring element is radially split and engages said groove.
Claim 5
Dependent Claim
29 words
A locking and sealing device according to claim 1, wherein said metal ring element comprises circumferentially spaced radial fingers having free ends engaging said one of said cylindrical surfaces.
Claim 6
Dependent Claim
32 words
A locking and sealing device according to claim 1, wherein said sealing element is in the form of an imperforate disc and is connected near the periphery of said metal ring element.
