Abstract
A spring loaded bearing assembly includes first and second matched cartridge bearings disposed within a bearing cup. A sleeve is disposed radially between the cartridge bearings and the bearing cup. A bushing is disposed radially within the cartridge bearings. A shaft is disposed radially within the bushing in sliding engagement therewith. An end cap is connected to the A spring biases the shaft axially.
Claims20
A spring-loaded bearing assembly comprising:
- a steel bearing cup having a sidewall and a first flange extending radially inwardly from a first end of the sidewall;
- a first cartridge bearing having an inner race and an outer race, the first cartridge bearing disposed within the steel bearing cup;
- a second cartridge bearing having an inner race and an outer race, the second cartridge bearing disposed within the steel bearing cup beside the first cartridge bearing;
- an annular sleeve having a sidewall disposed between the steel bearing cup and the respective outer races of the first cartridge bearing and the second cartridge bearing;
- an annular bushing having a sidewall disposed within and axially retained by the inner race of the first cartridge bearing and the inner race of the second cartridge bearing, the annular bushing extending axially through the first flange of the steel bearing cup;
- an end cap connected to an end of the annular bushing;
- a shaft having a spring perch proximate an end thereof, the shaft slidingly engaged with an interior surface of the annular bushing;
- and
- a biasing member disposed within an interior region of the annular bushing, the biasing member captured between the end cap and the spring perch, the biasing member configured to axially bias the shaft relative to the annular bushing.
