Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
97 words
A bearing comprising a support member having a bore therethrough to receive a rotatable shaft, said bore having a side wall formed by a shaft load carrying part and a shaft control part offset radially and longitudinally from said load carrying part by a shoulder, said load carrying part including segment means for bearing the load of said shaft, said control part including segment means separated from said load carrying part by said shoulder and located generally oppositely of the segment means of the load carrying part for restricting lateral movement of said shaft within said bore.
Claim 2
Dependent Claim
97 words
A bearing comprising a support member having a bore therethrough to receive a rotatable shaft, said bore having a side wall formed by a shaft load carrying part and a shaft control part offset radially and longitudinally from said load carrying part by a shoulder, said load carrying part including segment means for bearing the load of said shaft, said control part including segment means separated from said load carrying part by said shoulder and located generally oppositely of the segment means of the load carrying part for restricting lateral movement of said shaft within said bore.
Claim 3
Dependent Claim
23 words
The bearing of claim 1 wherein said control part includes a surface section colinear with the segment means of said load carrying part.
Claim 4
Dependent Claim
20 words
The bearing of claim 1 wherein said bore wall includes a single load carrying part and a single control part.
Claim 5
Dependent Claim
48 words
The bearing of claim 1 wherein said support member includes first and second end faces, the length of said bearing as measured between end faces being less than one-half the diameter of said bore as defined by the maximum transverse dimension of said load carrying and control parts.
Claim 6
Dependent Claim
24 words
The bearing of claim 1 wherein said control part is radially offset by said shoulder from the segment means of said load carrying part.
Claim 7
Dependent Claim
111 words
In combination a shaft and bearing, said bearing including a support member having a bore therethrough, said shaft being rotatably received within said bore, said bore having a side wall defined by a shaft load carrying part and a shaft control part offset radially and longitudinally from said load carrying part by a shoulder, said load carrying part including segment means for bearing the load of said shaft during rotation of the shaft, said control part including segment means separated from said load carrying part by said shoulder and located generally oppositely of the segment means of said load carrying part for restricting lateral movement of said shaft within said bore.
Claim 8
Dependent Claim
111 words
In combination a shaft and bearing, said bearing including a support member having a bore therethrough, said shaft being rotatably received within said bore, said bore having a side wall defined by a shaft load carrying part and a shaft control part offset radially and longitudinally from said load carrying part by a shoulder, said load carrying part including segment means for bearing the load of said shaft during rotation of the shaft, said control part including segment means separated from said load carrying part by said shoulder and located generally oppositely of the segment means of said load carrying part for restricting lateral movement of said shaft within said bore.
Claim 9
Dependent Claim
27 words
The combination bearing and shaft of claim 6 wherein said load carrying part and control part are colinear at the segment means of said load carrying part.
Claim 10
Dependent Claim
28 words
The combination bearing and shaft of claim 6 wherein said control part is offset from said load carrying part adjacent the segment means of the load carrying part.
Claim 11
Dependent Claim
28 words
The combination bearing and shaft of claim 8 wherein said control part extends radially beyond said load carrying part at the segment means of the load carrying part.
