Abstract
The invention includes a bearing assembly having concentric inner and outer races and roller elements disposed therebetween. Seal members are disposed on either side of the races, flanking the roller elements. The outer race is provided with circumferential grooves adjacent to each axial face of the outer race. Annular urging members are fitted between the races, adjoining the seal members on the outer sides thereof, urging the seals into contact with the races. The outer circumferential edge of each urging member extends into one of the grooves in the outer race. The urging members are biased such that the inner circumferential edge of each engages the adjacent seal and retains the inner race within the outer race in order to reduce wobble and vibration between the inner and outer races.
Claims5
A bearing comprising:
- an annular outer race having axial faces and first and second circumferential grooves formed adjacent to each axial face thereof;
- an inner race disposed concentrically within said first race, formed with first and second axial surfaces;
- roller elements disposed between said races;
- first and second seal members disposed on opposite sides of said races, said first seal member extending from said first groove to said first axial surface, said second seal member extending from said second groove to said second axial surface;
- first and second urging members disposed on opposite sides of said races, said first urging member extending from said first groove to said first axial surface, said second seal member extending from said second groove to said second axial surface, said urging members biased to urge said seal members against said axial surfaces, respectively, and said urging members biased to retain said inner race generally concentric within said outer race and reduce wobble and vibration therebetween.
