Axial retention assembly for axially fixing rotating parts with respect to each other

A method for creating an axial retention assembly, the axial retention assembly including a retainer ring, a first part having a first circumferential surface and a second part having a second circumferential surface,

• the retainer ring including a ring section, a set of first fingers each extending from the ring section radially in a first direction with respect to the center axis of the ring section;
• and a set of second fingers each extending from the ring section radially in the first direction with respect to the center axis of the ring section,
• the method comprising:
• installing the retainer ring onto the first part and the second part to cause the first fingers to snap into the first groove of the first part and to cause the second fingers to snap into the second groove of the second to prevent axial movement on both axial directions.

A retainer ring for axial fixing a first part and a second part with respect to each other to prevent the second part from being movable in both axial directions with respect to the first part, the retainer comprising:

• a ring section;
• a set of first fingers each extending from the ring section radially in a first direction with respect to the center axis of the ring section;
• and
• a set of second fingers each extending from the ring section radially in the first direction with respect to the center axis of the ring section,
• free ends of each of the second fingers being axially spaced from free ends of the first fingers;
• the free ends of the first fingers confirmed for being received in a first groove in a first circumferential surface of the first part,
• the free ends of the second fingers confirmed for being received in a second groove in a second circumferential surface of the first part.
