Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
91 words
A coupling for releasably connecting a rod to a driving shaft, comprising at least one flat surface on a peripheral end portion of said rod; a coupling socket attached to the face of the driving shaft, said socket having an open lateral side for receiving said one end portion of the rod and at least one flat inner wall matching the flat surface of said portion; and an exchangeable wearing piece fitting between the flat inner wall and the flat surface to transfer rotary moment from said shaft to said rod.
Claim 2
Dependent Claim
91 words
A coupling for releasably connecting a rod to a driving shaft, comprising at least one flat surface on a peripheral end portion of said rod; a coupling socket attached to the face of the driving shaft, said socket having an open lateral side for receiving said one end portion of the rod and at least one flat inner wall matching the flat surface of said portion; and an exchangeable wearing piece fitting between the flat inner wall and the flat surface to transfer rotary moment from said shaft to said rod.
Claim 3
Dependent Claim
25 words
A coupling as defined in claim 1, wherein said rod is a winding core of a roll processed on a machine including said driving shaft.
Claim 4
Dependent Claim
53 words
A coupling as defined in claim 1, wherein said end portion of said rod is formed with two opposite flat surfaces arranged symmetrically with respect to a central plane of the rod and said wearing piece including two wearing plates inserted between said flat surfaces and the corresponding inner walls of said socket.
Claim 5
Dependent Claim
37 words
A coupling as defined in claim 1, wherein said wearing piece is a one-piece removable receptacle matching the inner wall of said socket and including a recess for removably accommodating said coupling end portion of said rod.
Claim 6
Dependent Claim
20 words
A coupling as defined in claim 4, wherein said one-piece insert is secured to said socket by removable fastening means.
Claim 7
Dependent Claim
24 words
A coupling as defined in claim 1, wherein said socket is in the form of a tilting two-piece bearing defining an openable lateral side.
Claim 8
Dependent Claim
28 words
A coupling as defined in claim 6, wherein said wearing pieces are wearing plates insertable into said socket at right angles to the plane of said open side.
Claim 9
Dependent Claim
45 words
A coupling as defined in claim 6, wherein said socket has a cylindrical configuration and said wearing piece is a two-piece cylindrical inlet defining in one piece a recess for said coupling end part of said rod and the second piece closing said one piece.
Claim 10
Dependent Claim
28 words
A coupling as defined in claim 8, wherein said pieces of said wearing insert are secured by removable fastening means to the assigned pieces of said tilting bearing.
Claim 11
Dependent Claim
44 words
A coupling as defined in claim 1, wherein said wearing piece is formed with an opening extending between said flat inner wall and said flat surface, and further including a damping element arranged in said opening and exceeding the surfaces of said wearing plate.
Claim 12
Dependent Claim
27 words
A coupling as defined in claim 3, wherein each of said wearing plates is provided with a damping element projecting above the surface of the assigned plate.
Claim 13
Dependent Claim
30 words
A coupling as defined in claim 1, further including additional wearing pieces each having a different contour or thickness to adjust different configuration of the end pieces of said rods.
Claim 14
Dependent Claim
16 words
A coupling as defined in claim 1, wherein said wearing piece is made of hardened steel.
Claim 15
Dependent Claim
22 words
