Abstract
Abstract This invention is to provide a novel one-way clutch mechanism arranged characteristically such that a clutch ring so shaped as to be gradually increased in thickness from one side to the other is inserted between the inner and outer races through the media of sprag means inclined at a given angle relative to the axis of said inner and outer races, whereby the axial movements of said sprag means caused in conversion from and to the clutch action and the rolling action are all absorbed by said clutch ring.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A one-way clutch comprising an inner race, an outer race having an inner surface parallel to the axial direction thereof, a conoidal frame-like clutch ring shaped so as to increase in thickness from one side to the other relative to the axial direction of said inner and outer races and mounted between said inner and outer races, a plurality of sprags inclined at a certain predetermined angle relative to the axial direction of said inner and outer races and mounted between said inner and outer races and said clutch ring, so that any relative rotational movement of said inner and outer races in a first direction causes rolling action and rotation in the opposite direction causes locking action which is absorbed by said clutch ring.
Claim 2
Dependent Claim
125 words
A one-way clutch comprising an inner race, an outer race having an inner surface parallel to the axial direction thereof, a conoidal frame-like clutch ring shaped so as to increase in thickness from one side to the other relative to the axial direction of said inner and outer races and mounted between said inner and outer races, a plurality of sprags inclined at a certain predetermined angle relative to the axial direction of said inner and outer races and mounted between said inner and outer races and said clutch ring, so that any relative rotational movement of said inner and outer races in a first direction causes rolling action and rotation in the opposite direction causes locking action which is absorbed by said clutch ring.
Claim 3
Dependent Claim
35 words
A one-way clutch according to claim 1, in which guide flanges are provided on the reduced thickness side of said clutch ring and a thrust bearing mounted adjacent the thick side of said clutch ring.
Claim 4
Dependent Claim
20 words
A one-way clutch as defined in claim 1 including a pair of sprag cages in which said sprags are suppoRted.
Claim 5
Dependent Claim
19 words
A one-way clutch according to claim 1, in which said clutch ring is formed into a conoidal frame-like structure.
Claim 6
Dependent Claim
17 words
A one-way clutch according to claim 1, wherein said sprags are double-ball ended rollers having different sizes.
