Abstract
A motor assembly with improved sealing properties includes a motor having a rotatable shaft, a working air fan assembly carried by the shaft, the working air fan assembly moving air therethrough, and a sealed bearing interposed between the working air fan assembly, the sealed bearing having an inner ring rotatable with respect to an outer ring, and a seal carried by one of the rings, the seal frictionally contacting the other of the rings
Claims13
A motor assembly with improved sealing properties, comprising:
- a motor having a rotatable shaft;
- a working air fan assembly carried by said shaft, said working air fan assembly moving air therethrough;
- and
- a sealed bearing interposed between said working air fan assembly, said sealed bearing having an inner ring rotatable with respect to an outer ring, and a seal carried by one of said rings, said seal frictionally contacting the other of said rings.
A sealed bearing, comprising:
- an outer ring, said outer ring having an inner diameter;
- an inner ring, said inner ring having an outer diameter;
- a plurality of rolling elements disposed between said outer ring and said inner ring;
- and
- a seal carried by one of said rings, said seal frictionally contacting the other of said rings.
The bearing according to claim 10, wherein said inner diameter has at least one annular notch from which outwardly extends an annular lip, said annular notch and said annular lip securably receiving and supporting said seal.
The bearing according to claim 11, further comprising:
- a seal frame that carries said seal, said seal frame securably received in said annular notch.
The bearing according to claim 12, wherein said seal frame compresses at least a portion of said seal and urges an uncompressed portion of said seal into contact with the other of said rings.
