Abstract
A system for providing sealed shaft bearing is disclosed. The system can include housing and one or more end caps. The end caps can house one or more seals and one or more bearings for supporting a shaft. The housing can be watertight to prevent water from infiltrating the housing and to prevent lubricant, if any, from escaping the housing into the environment. The system can use a multi-piece design to facilitate repair and maintenance. The system can be easily retrofitted into systems, such as marine systems, that use conventional plain shaft bearings.
Claims18
A system for supporting a shaft comprising:
- a main housing;
- a first bearing end cap, comprising a first end and a second end, the first bearing end cap comprising:
- one or more bearings disposed in the first end of the first bearing end cap to at least partially support a shaft;
- and
- one or more seals, disposed in the second end of the first bearing end cap to provide a substantially watertight seal between the first bearing end cap and the shaft;
- wherein the first end of the first bearing end cap is detachably coupled to a first end of the main housing;
- and
- wherein the coupling between the first bearing end cap and the main housing is substantially watertight.
A system for supporting a shaft comprising:
- a main housing comprising a first end and a second end;
- a first bearing end cap, comprising a first end, a second end, the first end detachably coupled to the first end of the main housing;
- a second bearing end cap, comprising a first end, a second end, a second bearing, and a second seal, the first end detachably coupled to the second end of the main housing;
- a first bearing disposed in the first end of the first bearing end cap to partially support a shaft;
- a second bearing disposed in the first end of the second bearing end cap to partially support the shaft;
- a first seal disposed in the second end of the first bearing end cap to provide a substantially watertight seal between the shaft and the first bearing end cap;
- and
- a second seal disposed in the second end of the second bearing end cap to provide a substantially watertight seal between the shaft and the second bearing end cap;
- wherein the coupling between the first and second bearing end caps and the main housing is substantially watertight.
