Abstract
A hydrostatic bearing assembly and fluid return system is provided for collecting and returning hydrostatic fluid which exits the bearing assembly to a remote location. The bearing assembly and fluid return system includes a hydrostatic bearing which is connected to supply and return reservoirs by supply and return hoses or conduits, respectively. The bearing assembly includes a carriage having a bushing secured within the carriage between a pair of retaining rings. A collection cylinder is fixedly positioned between each retaining ring and one end of the bushing. Each collection cylinder defines a collection chamber adjacent one end of the carriage, which is positioned to receive hydrostatic fluid exiting a gap defined between the carriage and a support rail. The return hoses or conduits each have a first end that communicates with one of the collection chambers and a second end that communicates with remotely located reservoir. Hydrostatic fluid exiting the gap is collected in the collection chambers and subsequently returned to a collection reservoir.
