Abstract
A bearing assembly is disclosed herein. The bearing assembly includes an outer bearing ring including at least one first connection element. The assembly also includes a cap defining an axial portion and at least one radial portion defining a cavity configured to receive the outer bearing ring. The cap includes at least one second connection element configured to mate with the at least one first connection element. The cap is formed from an electrically insulating material to prevent EDM.
Claims17
A bearing assembly comprising:
- an outer bearing ring including at least one first connection element;
- and
- a cap including an axial portion and at least one radial portion defining a cavity configured to receive the outer bearing ring, the cap including at least one second connection element configured to mate with the at least one first connection element, wherein the cap is formed from an electrically insulating material;
- wherein the at least one first connection element comprises one of an axially extending groove or an axially extending rib, and the at least one second connection element comprises the other of an axially extending groove or an axially extending rib;
- wherein the outer bearing ring further comprises at least one additional first connection element, and the cap further comprises at least one additional second connection element;
- and
- wherein the at least one additional first connection element is formed as one of a post or a receptacle on an axial end face of the outer bearing ring, and the at least one additional second connection element is formed as the other one of a post or a receptacle on an axial end face of the cap.
A bearing assembly comprising:
- an outer bearing ring including at least one first connection element;
- and
- a cap including an axial portion and at least one radial portion defining a cavity configured to receive the outer bearing ring, the cap including at least one second connection element configured to mate with the at least one first connection element, wherein the cap is formed from an electrically insulating material;
- a face cover arranged on a first axial end of the outer bearing ring and the cap;
- and wherein the face cover includes at least one first face cover connection element and at least one second face cover connection element, wherein the at least one first face cover connection element is configured to engage with the cap and the at least one second face cover connection element is configured to engage with the outer bearing ring.
A bearing assembly comprising:
- an outer bearing ring including at least one first connection element;
- and
- an electrically insulating cap defining a cavity configured to receive the outer bearing ring, the cap including at least one second connection element configured to mate with the at least one first connection element, wherein the cap and the outer bearing ring are configured to be connected to each other via application of at least one of rotational force or axial force to at least one of the cap or the outer bearing ring;
- and
- a face cover arranged on a first axial end of the outer bearing ring and the cap;
- wherein the face cover includes at least one first face cover connection element and at least one second face cover connection element, wherein the at least one first face cover connection element is configured to engage with the cap and the at least one second face cover connection element is configured to engage with the outer bearing ring.
