Abstract
A bearing for retro-fit or repair of an engine provides high reliability through a sleeved bearing design having externally-supplied lubrication. The bearing assembly may be supplied as a kit including a lubrication delivery tube and an oil filter adapter having a port for supplying the external lubrication to a mounting flange of the bearing. In order to install the bearing a captive sleeve is inserted in a hollow end of the shaft being supported. A cap having a threaded stud is inserted with the sleeve into the hollow end of the shaft and secured by the required snap ring. Then a nut is used to secure the cap and the sleeve to a stud affixed to the mounting flange that secures the bearing assembly to the engine.
Claims17
An end bearing assembly for mounting to an external surface of an engine and supporting an end of a rotary shaft of the engine, the end bearing assembly comprising:
- a rotating bearing for coupling to an end of the rotary shaft, wherein the rotating bearing comprises a bushing for coupling to an end of the rotary shaft and a stud for insertion into the bushing and on which the bushing rotates;
- a flange mechanically secured to the bearing for mounting the end bearing assembly to the external surface of the engine;
- and
- an oil delivery system comprising a tube coupled to a first port on the flange for delivering pressurized oil to surfaces of the rotating bearing from a source of pressurized oil of the engine, wherein the oil delivery system supplies lubrication to the bushing and the stud through an oil channel extending from the first port through the flange.
An end bearing assembly for supporting an end of a rotary shaft, comprising:
- a bushing for captive insertion within the end of the rotary shaft;
- a stud for insertion into the bushing and on which the bushing rotates;
- and
- a flange mechanically secured to the stud for mounting the end bearing assembly to an external surface of an engine.
A method of supporting an end of a rotary shaft of an engine, comprising:
- coupling an end of the rotary shaft to a bushing of a bearing;
- inserting a stud of the bearing into the bushing, wherein the stud is mechanically connected to a flange and wherein the bushing rotates on the stud;
- securing the flange to an outer surface of the engine;
- and
- supplying lubrication to the bushing and the stud of the bearing through a tube extending from a source of pressurized oil of the engine through a first port on the flange that is coupled to a channel extending through the flange.
