Roller one way clutch cage retention

A one way clutch assembly comprising:

• a housing with an opening having a first ramped portion and a groove defined on an inner periphery of the opening;
• and
• a cage defining a plurality of rolling element pockets and including a first rim with a second ramped portion that corresponds to the first ramped portion, the first ramped portion of the housing is aligned with the second ramped portion of the cage during insertion of the cage into the opening of the housing for axial alignment of the second ramped portion and the groove, and upon rotation of the cage with respect to the housing, the second ramped portion overlaps the first ramped portion to retain the cage in the housing, further comprising rolling elements arranged within the plurality of rolling element pockets of the cage, and an inner supported member having an outer diameter, wherein:
• (1) in a pre-installed state, the rolling elements engage a first region of the first ramped portion of the housing, and the rolling elements define a first inner diameter;
• and
• (2) in an installed state, the cage is rotated with respect to the housing to move the rolling elements outwardly along the first ramped portion to a second region of the first ramped portion of the housing, the cage and the housing are then arranged on the inner supported member, and the outer diameter of the inner supported member is greater than the first inner diameter of the rolling elements such that the rolling elements are prevented from returning to the first region of the first ramped portion of the housing.

A method for retaining a cage in a one way clutch, the method comprising:

• providing a housing with an opening having a first ramped portion and a groove defined on an inner periphery of the opening;
• providing a cage defining a plurality of rolling element pockets and including a first rim with a second ramped portion that corresponds to the first ramped portion, wherein the cage includes a second rim having a first outwardly extending tab, and the housing includes a first retention cavity that receives the first outwardly extending tab of the second rim;
• aligning the first ramped portion of the housing and the second ramped portion of the cage;
• inserting the cage into the opening of the housing;
• aligning the second ramped portion of the cage with the groove in an axial direction;
• and
• rotating the cage with respect to the housing so that the second ramped portion overlaps the first ramped portion to retain the cage in the housing.
