Abstract

Abstract This specification discloses a one-way clutch rolling member holder for holding a plurality of rolling members disposed between the annular inner surface of an outer race and the annular outer surface of an inner race and intermittently transmitting a torque, characterized in that the holder has a plurality of holding surfaces disposed between the rolling members, and some or all of the holding surfaces have a planar portion bearing against the annular inner surface of the outer race or the annular outer surface of the inner race. The specification also disclosed a one-way clutch having such holder.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 241 words
A one-way clutch comprising: (a) an outer race having an annular inner surface; (b) an inner race having an annular outer surface and disposed coaxially with said outer race; (c) a plurality of sprags spaced circumferentially at a predetermined interval between said inner surface and said outer surface, and engageable with said inner surface and said outer surface by tilting in a peripheral direction of said surfaces to transmit a torque between said two races; and (d) a sprag holder for holding said sprags in an annular space between said annular surfaces, said sprag holder including: (i) two annular band portions for supporting both sides of said sprags with respect to said peripheral direction, between said inner surface and said outer surface; and (ii) connecting portions for connection said two annular band portions, said connecting portions being positioned between said sprags and supporting the front and the rear of said sprags with respect to said peripheral direction, said connecting portions having friction engagement means frictionally engaged with one of said inner surface and said outer surface; said friction engagement means having a bearing portion bearing against said one surface, an extending portion extending between one end of said bearing portion and one of said two band portions, and a free end portion provided at another end of said bearing portion; said bearing portion, said extending portion, and said free end portion being aligned in an axial direction of said annular bands.
Claim 2
Dependent Claim 241 words
A one-way clutch comprising: (a) an outer race having an annular inner surface; (b) an inner race having an annular outer surface and disposed coaxially with said outer race; (c) a plurality of sprags spaced circumferentially at a predetermined interval between said inner surface and said outer surface, and engageable with said inner surface and said outer surface by tilting in a peripheral direction of said surfaces to transmit a torque between said two races; and (d) a sprag holder for holding said sprags in an annular space between said annular surfaces, said sprag holder including: (i) two annular band portions for supporting both sides of said sprags with respect to said peripheral direction, between said inner surface and said outer surface; and (ii) connecting portions for connection said two annular band portions, said connecting portions being positioned between said sprags and supporting the front and the rear of said sprags with respect to said peripheral direction, said connecting portions having friction engagement means frictionally engaged with one of said inner surface and said outer surface; said friction engagement means having a bearing portion bearing against said one surface, an extending portion extending between one end of said bearing portion and one of said two band portions, and a free end portion provided at another end of said bearing portion; said bearing portion, said extending portion, and said free end portion being aligned in an axial direction of said annular bands.
Claim 3
Dependent Claim 20 words
A one-way clutch according to claim 1, wherein said bearing portion bears against said inner surface of the outer race.
Claim 4
Dependent Claim 20 words
A one-way clutch according to claim 1, wherein said bearing portion bears against said outer surface of the inner race.
Claim 5
Dependent Claim 22 words
A one-way clutch according to claim 1, wherein said free end portion is directed toward the other of said two band portions.
Claim 6
Dependent Claim 231 words
A sprag holder for holding sprags in a one-way clutch which includes: (a) an outer race having an annular inner surface: (b) an inner race having an annular outer surface and disposed coaxially with said outer race; and (c) a plurality of sprags spaced circumferentially at a predetermined interval between said inner surface and said outer surface, and engageable with said inner surface and said outer surface by tilting in a peripheral direction of said surfaces to transmit a torque between said two races; said sprag holder comprising: (i) two annular band portions for supporting both sides of said sprags with respect to said peripheral direction, between said inner surface and said outer surface; and (ii) connecting portions for connecting said two annular band portions, said connecting portions being positioned between said sprags and supporting the front and the rear of said sprags with respect to said peripheral direction, said connecting portions having friction engagement means frictionally engaged with one of said inner and outer surfaces; said friction engagement means including a bearing portion bearing against said one surface, an extending portion extending between one end of said bearing portion and one of said two band portions, and a free end portion provided at another end of said bearing portion; said bearing portion, said extending portion, and said free end portion being aligned in an axial direction of said annular bands.
Claim 7
Dependent Claim 231 words
A sprag holder for holding sprags in a one-way clutch which includes: (a) an outer race having an annular inner surface: (b) an inner race having an annular outer surface and disposed coaxially with said outer race; and (c) a plurality of sprags spaced circumferentially at a predetermined interval between said inner surface and said outer surface, and engageable with said inner surface and said outer surface by tilting in a peripheral direction of said surfaces to transmit a torque between said two races; said sprag holder comprising: (i) two annular band portions for supporting both sides of said sprags with respect to said peripheral direction, between said inner surface and said outer surface; and (ii) connecting portions for connecting said two annular band portions, said connecting portions being positioned between said sprags and supporting the front and the rear of said sprags with respect to said peripheral direction, said connecting portions having friction engagement means frictionally engaged with one of said inner and outer surfaces; said friction engagement means including a bearing portion bearing against said one surface, an extending portion extending between one end of said bearing portion and one of said two band portions, and a free end portion provided at another end of said bearing portion; said bearing portion, said extending portion, and said free end portion being aligned in an axial direction of said annular bands.
Claim 8
Dependent Claim 20 words
A sprag holder according to claim 5, wherein said bearing portion bears against said inner surface of the outer race.
