Abstract
Abstract A bearing comprising at least one intermediate idling race rotatable between fixed and rotating races and a predetermined number of sets of elastic sleeve and roller distributed outside and inside the idling race between the fixed and rotating races. The sleeve encloses therewithin the roller having a diameter slightly smaller than the inner diameter of the sleeve. The sleeves roll is compressed between the races against the rollers so that the idling race can rotate at a controlled speed as the rotating race rotates.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A bearing comprising at least one idling member rotatable between and substantially concentrically with a fixed member and a rotating member and a plurality of elastic sleeve and roller sets distributed between said idling member and at least one of said rotating and fixed members, such that in each of said sets said sleeve is compressed radially against two points on said roller between said members, said sleeve enclosing therewithin said roller and said roller having a diameter slightly smaller than the inner diameter of said sleeve, the number of the sleeve and roller sets being selected so as to adjust the relative frictional resistance between said fixed and idling members and between said idling and rotating members, thereby allowing said idling member to rotate at a predetermined speed as said rotating member rotates.
Claim 2
Dependent Claim
134 words
A bearing comprising at least one idling member rotatable between and substantially concentrically with a fixed member and a rotating member and a plurality of elastic sleeve and roller sets distributed between said idling member and at least one of said rotating and fixed members, such that in each of said sets said sleeve is compressed radially against two points on said roller between said members, said sleeve enclosing therewithin said roller and said roller having a diameter slightly smaller than the inner diameter of said sleeve, the number of the sleeve and roller sets being selected so as to adjust the relative frictional resistance between said fixed and idling members and between said idling and rotating members, thereby allowing said idling member to rotate at a predetermined speed as said rotating member rotates.
Claim 3
Dependent Claim
41 words
A bearing as claimed in claim 1, and further comprising at least one roller between said idling member and at least one of said fixed and rotating members, said roller being larger in diameter than said roller enclosed within said sleeve.
Claim 4
Dependent Claim
21 words
A bearing as claimed in claim 1 further comprising spacers placed across at least one of said sleeve and roller sets.
Claim 5
Dependent Claim
103 words
A sliding bearing comprising at least one idling member rotatable slidably between and substantially concentrically with a fixed member and a rotating member and a predetermined number of elastic sleeves distributed in spaces formed between said idling member and at least one of said rotating and said fixed members, such that said sleeve is compressed radially between said members, the number of said sleeves being selected so as to adjust the relative frictional resistance between said rotating and idling members and between said fixed and idling members, thereby allowing said idling member to rotate at a predetermined speed as said rotating member rotates.
Claim 6
Dependent Claim
103 words
A sliding bearing comprising at least one idling member rotatable slidably between and substantially concentrically with a fixed member and a rotating member and a predetermined number of elastic sleeves distributed in spaces formed between said idling member and at least one of said rotating and said fixed members, such that said sleeve is compressed radially between said members, the number of said sleeves being selected so as to adjust the relative frictional resistance between said rotating and idling members and between said fixed and idling members, thereby allowing said idling member to rotate at a predetermined speed as said rotating member rotates.
Claim 7
Dependent Claim
19 words
A sliding bearing as claimed in claim 4 further comprising spacers placed across at least one of said sleeves.
