Abstract

Abstract Assembly of a shaft and a connecting element comprising a split collar of sheet metal having ear portions. The split is wide enough to allow the shaft to pass radially therethrough. An intermediate member is disposed in the split and bears against the shaft. A bolt and nut tightening means extends through the ear portions and the intermediate member co-operates with faces on the ear portions and/or with a face on the tightening means. The arrangement is such that a relative displacement between the ear portions, the intermediate member and the tightening means causes the shaft to be gripped inside the collar.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 240 words
An assembly of a shaft having an axis and a face with a connecting element constituted by a cold-formed sheet metal member having a portion defining a collar which is coaxial with and encompasses the shaft and comprises two longitudinally extending edge portions defining a throughway split in the collar and two ear portions which extend from said edge portions and have surfaces, said surfaces being spaced apart from each other such distance and said split having such width as to allow the collar to be mounted on the shaft by a relative radial displacement of the shaft and collar, tightening means extending through the ear portions and having a surface, an intermediate holding member located between the ear portions and having a face which engages said face of the shaft and having at least one other face which co-operates with at least one of said surfaces, whereby a relative displacement between the ear portions, the intermediate member and the tightening means causes the shaft to be gripped inside the collar, said shaft having a portion defining a non-circular keying face and one of two component parts of the assembly consisting of said intermediate member and said collar having a portion defining a non-circular keying face keyingly engaged with the keying face of said shaft, and means defining a bridge which is axially adjacent said ear portions and rigidly interconnects said edge portions and closes one end of said split.
Claim 2
Dependent Claim 240 words
An assembly of a shaft having an axis and a face with a connecting element constituted by a cold-formed sheet metal member having a portion defining a collar which is coaxial with and encompasses the shaft and comprises two longitudinally extending edge portions defining a throughway split in the collar and two ear portions which extend from said edge portions and have surfaces, said surfaces being spaced apart from each other such distance and said split having such width as to allow the collar to be mounted on the shaft by a relative radial displacement of the shaft and collar, tightening means extending through the ear portions and having a surface, an intermediate holding member located between the ear portions and having a face which engages said face of the shaft and having at least one other face which co-operates with at least one of said surfaces, whereby a relative displacement between the ear portions, the intermediate member and the tightening means causes the shaft to be gripped inside the collar, said shaft having a portion defining a non-circular keying face and one of two component parts of the assembly consisting of said intermediate member and said collar having a portion defining a non-circular keying face keyingly engaged with the keying face of said shaft, and means defining a bridge which is axially adjacent said ear portions and rigidly interconnects said edge portions and closes one end of said split.
Claim 3
Dependent Claim 29 words
An assembly as claimed in claim 1, wherein said bridge comprises parts of said edge portions of said collar and a weld interconnecting said parts of said edge portions.
Claim 4
Dependent Claim 189 words
An assembly comprising a shaft portion having an axis and two substantially plane faces and a third face, and a connecting element constituted by a cold-formed sheet metal member having a portion defining a collar which is coaxial with and encompasses the shaft portion and comprises two longitudinally extending edge portions defining a throughway split in the collar and two ear portions which extend outwardly from said edge portions, said collar being substantially V-shaped in cross section and having two substantially plane portions engaging said substantially plane faces of the shaft portion, said ear portions being spaced apart from each other such distance and said split having such width as to allow the collar to be mounted on the shaft portion by a relative radial displacement of the shaft portion and collar, an intermediate member bearing against said third face of the shaft portion, tightening means for drawing said intermediate member toward said ear portions and clamping said intermediate member against said third face, and means defining a bridge which is axially adjacent said ear portions and rigidly interconnects said edge portions and closes one end of said split.
Claim 5
Dependent Claim 189 words
An assembly comprising a shaft portion having an axis and two substantially plane faces and a third face, and a connecting element constituted by a cold-formed sheet metal member having a portion defining a collar which is coaxial with and encompasses the shaft portion and comprises two longitudinally extending edge portions defining a throughway split in the collar and two ear portions which extend outwardly from said edge portions, said collar being substantially V-shaped in cross section and having two substantially plane portions engaging said substantially plane faces of the shaft portion, said ear portions being spaced apart from each other such distance and said split having such width as to allow the collar to be mounted on the shaft portion by a relative radial displacement of the shaft portion and collar, an intermediate member bearing against said third face of the shaft portion, tightening means for drawing said intermediate member toward said ear portions and clamping said intermediate member against said third face, and means defining a bridge which is axially adjacent said ear portions and rigidly interconnects said edge portions and closes one end of said split.
Claim 6
Dependent Claim 67 words
An assembly as claimed in claim 3, wherein said tightening means comprise apertures in said intermediate member and in said ear portions and a substantially V-shaped stirrup extending around said collar and having two screwthreaded end portions extending through said apertures, and nuts engaged on said screwthreaded end portions and bearing against said intermediate member on a side of said intErmediate member remote from said ear portions.
Claim 7
Dependent Claim 48 words
An assembly as claimed in claim 3, wherein said bridge comprises a tab portion which is an integral part of said sheet metal member and extends from one of said edge portions across said split, and means fixing said tab portion to the other of said edge portions.
Claim 8
Dependent Claim 14 words
An assembly as claimed in claim 5, wherein said fixing means is a weld.
Claim 9
Dependent Claim 41 words
An assembly as claimed in claim 3, wherein said bridge comprises two tab portions which are integral parts of said sheet metal member and respectively extend from said edge portions across said split, and fixing means rigidly interconnecting said tab portions.
Claim 10
Dependent Claim 14 words
An assembly as claimed in claim 7, wherein said fixing means is a weld.
Claim 11
Dependent Claim 28 words
An assembly as claimed in claim 3, wherein said bridge comprises a bar extending across said split and means rigidly fixing said bar to said two edge portions.
Claim 12
Dependent Claim 14 words
An assembly as claimed in claim 9, wherein said fixing means is a weld.
Claim 13
Dependent Claim 21 words
An assembly as claimed in claim 3, wherein said collar has a circular cross-sectional shape in the region of said bridge.
