## Abstract

An roller clutch assembly that includes an outer race with a plurality of cam surfaces circumferentially spaced apart from each adjacent cam surface having a shallow end and a deep end further radially recessed into the outer race and an inner race having circumferentially spaced splines on an inner surface. A roller clutch assembly is disposed adjacent the inner race, and at least two spiral lock snap rings, wherein one spiral lock snap ring is disposed adjacent the outer race.

## Claims

### Claim 1

A roller clutch assembly comprising:
an outer race with a plurality of cam surfaces circumferentially spaced apart from each adjacent cam surface having a shallow end and a deep end further radially recessed into the outer race, wherein a first slot and a second slot are disposed within the cam surface, and a void extends through the outer race;
a first spiral lock snap ring positioned within the first slot;
an inner race having an exterior surface, an interior surface, and an interior void, wherein the interior surface contains a plurality of teeth circumferentially spaced apart from each adjacent tooth;
an inner retainer plate disposed adjacent the inner race;
a cage having an outer ring and an inner ring spaced apart and interconnected by a top portion and a bottom portion extending between the outer ring and the inner ring, and a plurality of spaced apart ribs extend from the outer ring, defining a plurality of windows between each rib for receiving rollers and roller springs; and
a second spiral lock snap ring positioned within the second slot.

### Claim 2 (depends on 1)

The roller clutch assembly according to claim 1, wherein the cage is composed of metal.

### Claim 3 (depends on 1)

The roller clutch assembly according to claim 1, further comprising an inner retainer plate disposed adjacent the inner race.

### Claim 4 (depends on 1)

The roller clutch assembly according to claim 1, further comprising an outer retainer plate.

### Claim 5

A roller clutch assembly comprising:
an outer race with a plurality of cam surfaces circumferentially spaced apart from each adjacent cam surface having a shallow end and a deep end further radially recessed into the outer race, wherein a first slot and a second slot are disposed within the cam surface, and a void extends through the outer race;
a first spiral lock snap ring contains an outer edge positioned within the first slot;
an inner race having an exterior surface, an interior surface, and an interior void, wherein the interior surface contains a plurality of teeth circumferentially spaced apart from each adjacent tooth;
an inner retainer plate disposed adjacent the inner race;
a cage having an outer ring and an inner ring spaced apart and interconnected by a top portion and a bottom portion extending between the outer ring and the inner ring, and a plurality of spaced apart ribs extend from the outer ring, defining a plurality of windows between each rib for receiving rollers and roller springs;
an outer retainer plate; and
a second spiral lock snap ring contains an outer edge positioned within the second slot.

### Claim 6 (depends on 5)

The roller clutch assembly according to claim 5, further comprising at least one seat is disposed between the plurality of teeth on the inner surface of the inner race.

### Claim 7 (depends on 5)

The roller clutch assembly according to claim 5, further comprising three seats dispersed between the plurality of teeth on the inner surface of the inner race and spaced an equal distance apart from each other.
