Abstract
A self aligning bearing and seal assembly including a bearing housing operable to mount to a surface, a bearing unit seated within the bearing housing and having an outer race, an inner race, and at least one ball intermediate the outer and inner race. The self aligning bearing and seal assembly also includes a pivot assembly having a shaft sleeve operable for receiving and maintaining a rotatable shaft and being disposed in the bearing housing and in operational contact with the inner race of the bearing unit. The pivot assembly allows for a degree of angular misalignment between the surface and the shaft greater than three degrees.
Claims29
A self aligning bearing and seal assembly, comprising:
- a bearing housing defining an internal cavity and being operable to mount to a surface;
- a pivot assembly having a bearing holder operable for receiving and maintaining a rotatable shaft, the pivot assembly being disposed in the bearing housing;
- a bearing unit disposed within the pivot assembly being in operational contact with the pivot assembly;
- and
- a plurality of bearing and housing seals located about the bearing unit,
- wherein the pivot assembly maintains the alignment and integrity of the bearing unit, the bearing and housing seals, and the shaft up to 20 degrees of displacement between the surface and the rotatable shaft.
A self aligning bearing and seal assembly, comprising:
- a bearing housing defining an internal cavity;
- a pivot assembly defining a seat and having a shaft sleeve operable for receiving and maintaining a rotatable shaft and a bearing unit, the pivot assembly being disposed in the bearing housing;
- and
- a plurality of bearing and housing seals located about the bearing unit,
- wherein the pivot assembly maintains the alignment and integrity of the bearing unit, the bearing and housing seals, and the shaft up to 20 degrees of displacement between the surface and the rotatable shaft.
A self aligning bearing and seal system, comprising:
- a radial bearing assembly operable to mount to a first side of a surface;
- a radial pivot assembly disposed within the radial bearing assembly and comprising a first seal and a first bearing unit, wherein the first seal and first bearing unit are disposed to a first sleeve operable to receive a rotatable shaft;
- a thrust bearing assembly operable to mount to a second side of a surface;
- a thrust pivot assembly disposed within the thrust bearing assembly and comprising a second seal and a second bearing unit, wherein the second seal and second bearing are disposed to a second sleeve operable to receive the rotatable shaft;
- wherein the radial bearing assembly and the thrust bearing assembly cooperate to allow misalignment between respective surfaces of the assemblies and the rotatable shaft up to 20 degrees.
