Abstract
A ball bearing set having a circumferential gap in each race, the outer radius of the outer race being decreased in the region of the gap in the outer race, and the inner radius of the inner race being increased in the region of the gap in the inner race.
Claims11
A ball bearing combination comprising:
- a ball bearing set having split inner and outer races with first and second circumferential segments removed, respectively, from said inner and outer races to form first and second gaps in said races, and a plurality of ball bearings between said races;
- a shaft within said inner race;
- a housing surrounding said outer race;
- axial loading means on said bearing races to force said inner race into engagement with said shaft and said outer race into engagement with said housing;
- the outer radius of said outer race being diminished in the region of said first gap in said outer race to form a first opening between said outer race and said housing to cause opposing ends of said outer race to become a first set of cantilevered springs;
- the inner radius of said inner race being enlarged in the region of said second gap in said inner race to form a second opening between said inner race and said shaft to cause opposing ends of said inner race to become a second set of cantilevered springs;
- said first and second sets of cantilevered springs being flexible to reduce torque pulses, delivered by said ball bearings as they cross said gaps.

In combination:
- a ball bearing set having a split outer race with a segment removed therefrom to divide the circumference of said outer race to form a gap, an inner race, and a plurality of ball bearings positioned between said races to cross the gap produced by said removed segment;
- the outer radius of said outer race being diminished across its full axial dimension in the region of said gap to form a first set of opposing cantilevered spring ends, whereby torque pulses, produced by said ball bearings as they cross said gap, are reduced.
In combination:
- a ball bearing set having a split inner race with a segment removed therefrom to divide the circumference of said inner race to form a gap, an outer race, and a plurality of ballbearings positioned between said races to cross the gap produced by said removed segment;
- the inner radius of said inner race being enlarged across its full axial dimension in the region of said gap to form a set of opposing cantilevered spring ends, whereby torque pulses, produced by said ball bearings as they cross said gap, are reduced.
