Abstract
A hydraulically operated motor may be located in an atmosphere having substantially high and varying pressure. The motor may be provided with conduits that are in fluid communication with cavities adjacent to the motor bearings, so that fluid in the conduits may lubricate the bearings. Lubricating fluid may be introduced to the conduits across an air gap that is in the atmosphere having substantially high and varying pressure, and the fluid may thereby pass through and lubricate the bearings.
Claims15
A hydraulically operated motor for use in a high-pressure environment, comprising:
- a motor housing defining an interior portion;
- a first bearing positioned in the interior portion of the motor housing;
- a drive shaft rotatably mounted in the first bearing;
- a first fluid receptacle in fluid communication with at least one surface of the first bearing;
- and
- a first fluid supply conduit for providing fluid to the first fluid receptacle and spaced apart from the first fluid receptacle by an air gap in the high-pressure environment.
A method for lubricating a motor having a bearing in a high-pressure environment, comprising:
- providing a fluid receptacle in fluid communication with at least one surface of the bearing;
- directing a flow of lubricating fluid into the fluid receptacle across an air gap in the high-pressure environment.
