摘要： A rotary unit with a built-in clutch which is short in its axial length. The rotary unit has an inner member having an outer periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the raceway groove, and a cylindrical outer member having an inner periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the groove. A retainer mounted between the inner and outer members has a plurality of circumferentially spaced pockets each housing a rolling member and sprag housing recesses provided alternately with the pockets. In each recess is received a sprag having both ends thereof resting on the opposing cylindrical surfaces and biased by a resilient member so that its inner and outer arcuate surfaces contact the cylindrical surfaces. By arranging the sprags and the rolling members alternately with each other in the circumferential direction, it is possible to reduce the entire axial length of the rotary unit.

摘要： An end bearing for a one-way clutch is disclosed. The end bearing is provided in its inner or outer peripheral wall with at least one lube oil groove which is oblique to a central axis of the one-way clutch to introduce a lube oil into the one-way clutch. The lube oil groove is formed with varied widths, depths and/or shapes in cross-section from an outer opening on a side opposite to clutch members to an inner opening on a side of the clutch members.

摘要： A one-way includes a drag strip between a retainer and a driver ring to ensure transmission of rotation of the driver ring to engagement members such as sprags even when the driver ring is abruptly accelerated or is driven at a high speed. The drag strip has a sliding main body which, after assembly of the drag strip in the one-way clutch, is maintained in contact with the driver ring. The drag strip also has a hanger which extends at a right angle from at least one of opposite ends of the sliding main body into an engagement-member-receiving window of the retainer. On a side edge of the drag strip, where the drag strip is normally maintained in contact with an edge of the engagement-member-receiving window of the inner retainer, the drag strip has an engagement portion engageable with the edge the engagement-member-receiving window. The engagement portion is located in the same plane as the side edge of the hanger. The hanger is maintained in engagement with the retainer by the engagement portion.

摘要： In a one-way clutch, an outer ring has an internal portion whose hardness is substantially the same as that of its periphery, both hardnesses preferably being HRC 55 or more. When sprags interposed between the outer ring and inner ring are engaged with an inner peripheral surface of the outer ring and press the inner peripheral surface radially outwardly, the internal portion having the hardness of HRC 55 or more backs up the inner peripheral surface to prevent the inner peripheral surface from being deformed radially outwardly. Therefore, "roll-over" can be prevented and the maximum transmission torque is increased.

摘要： A retainer plate (70) limits axial displacement of two rotating rings (16,42) by providing a blocking surface contacted by the rings. An anti-friction bearing (82) includes radially directed tabs (88) that overlap the retainer plate and limit axial movement of the retainer plate and the rotating rings. The tabs of the bearing are formed integrally with a race (86) that rotatably supports roller elements (94).

摘要： A locking element freewheel comprising an outer race ring (1) and an inner race ring (2) with cylindrical and mutually concentric locking surfaces (7,8) between which tiltably suspended locking elements (5) are guided in a cage (6) wherein the central portion of the locking surfaces (7,8) of the outer race ring (1) or inner race ring (2) has a smaller or larger diameter than the ends thereof. If, due to differing wall thicknesses, the race rings (1,2) have differing rigidity, the edge region of highest rigidity of the locking surfaces (7,8) of the outer race ring (1) and/or inner race ring (2) has a larger or smaller diameter and by such a profiling of the locking surfaces, an overloading at the edges of the locking elements is prevented.

摘要： An improved overrunning clutch roller energizing spring of the type that has a series of flat leaves forming V's with energy storing folds or pleats at the peak of each V. The front and rear leaves of the spring each have an integrally formed end loop with a diameter greater than the height beyond which the spring should not be compressed. The loop diameter is less than the space differential available between the spring pleats and the side rails. When the spring compresses back toward the roller pocket base, the loops hit on each side of the spring, preventing the spring from compressing further than its solid height. The end loops do not hit or rub on the spring pleats, and prevent the spring pleats from rubbing on the pocket side rails.

摘要： In a one-way clutch, an outer retainer is made of a plastic while an inner retainer is made of a fiber-reinforced plastic. Thus, this one-way clutch is lightweight and can be produced at a low cost. The fiber-reinforced plastic of the inner retainer has a greater strength than the plastic of the outer retainer so that inner portions of sprags that serve as center portions about which the sprags swing can be retained by the inner retainer more securely than can the outer portions of the sprags be retained by the outer retainer.

摘要： A one-way sprag clutch assembly for use in an automatic transmission or slar application including an inner race (42), an outer race (44) having a pair of annular grooves (63, 68) cut in the interior surface (45) thereof, and a clutch assembly (41) having an inner cage member (46), an outer cage member (53) and an intermediate energizing spring (49), the cage members and spring having generally aligned openings (47, 51, 55) for receiving a plurality of sprags (48) therein. A side wall (56) is integrally formed with and perpendicular to the outer annular cage member (53) to create, with an end cap (64) on the opposite end of the assembly, lubrication escape barriers for lubricant in the assembly. The side wall (56) further includes either an integrally formed annular protrusion or a plurality of radially extending axial positioning protrusions (62) received in one of the annular grooves (63) to cooperate with a snap ring (67) received in the other grooves (68) to retain the clutch assembly (41) from axial movement with respect to the races (42, 44). Drag lands (58) are integrally formed on a plurality of spaced crossbars (57) in the cage member and extend radially outwardly from the crossbars (57) to terminate in arcuate surfaces (61) engaging the interior surface (45) of the outer race (44) to provide for inertial resistance for the clutch assembly (41) relative to the races (42, 44).
