Motor housing design for rotor-axial-displacement-independent and mounting-orientation-independent ingress protection
Embodiments herein relate to a motor housing for ingress protection and a method of assembly thereof. In accordance with at least one aspect, there is provided a motor housing assembly for retaining an electric motor, comprising: a housing body portion extending along a housing axis between a first end and a second end; an end flange member coupled to the first end of the housing body, the end flange further comprising an exterior surface and an interior surface and a shaft-receiving opening extending between the exterior and interior surfaces for receiving a shaft of the electric motor, wherein the exterior surface comprising a groove surrounding the shaft-receiving opening; a sealing assembly disposed around the shaft-receiving opening of the end flange, the sealing assembly comprising: a flinger seal extending between a first and a second end, wherein the second end is receivable inside of the groove.
1 . A motor housing assembly for retaining an electric motor, comprising:
a housing body portion extending along a housing axis between a first end of the housing body and a second end of the housing body;
an end flange member coupled to the first end of the housing body, the end flange further comprising an exterior surface and an interior surface and a shaft-receiving opening extending between the exterior and interior surfaces for receiving a shaft of the electric motor, wherein the exterior surface comprising a groove surrounding the shaft-receiving opening;
a sealing assembly disposed around the shaft-receiving opening of the end flange, the sealing assembly comprising:
a flinger seal extending between a first and a second end of the flinger seal, wherein the second end of the flinger seal is receivable inside of the groove; and
a contact seal disposed under the flinger seal and over the front surface of the end flange.
2 . The motor housing of claim 1 , wherein the second end of the flinger seal is axially translatable inside the groove.
3 . The motor housing of claim 1 , wherein the sealing assembly further comprises a radial shaft seal disposed inside an interior of the housing body portion and in contact with the interior surface of the end flange member.
4 . The motor housing assembly of claim 1 , wherein the flinger seal is tapered outwardly between the first and second end of the flinger seal.
5 . The motor housing of claim 1 , wherein the flinger seal is rotatable with the motor shaft.
