Abstract
The improved bearing system includes an inner cartridge and an outer cartridge having respective bearing units configured to be mountable to a common axial shaft. A drain port is formed in the outer cartridge for discharging excess oil from the bearing system. An annular channel is generally formed from one of the cartridges for selectively receiving a preload ring. An annular groove is formed from a portion of the other cartridge and sized to slidably receive the preload ring. A preload element is disposed within the annular groove and axially compressed between a preload surface of the annular groove and the preload ring. The preload element maintains a simultaneous axial preload thrust on the bearing cartridges and respective bearing units in inwardly opposite axial directions.
Claims20
An improved bearing system, comprising:
- an inner cartridge and an outer cartridge, each of said cartridges having respective bearing units configured to be mountable to a common axial shaft;
- a drain port formed in the outer cartridge for discharging excess oil from the bearing system;
- an annular channel generally formed from one of the inner cartridge or the outer cartridge for selectively receiving a preload ring;
- an annular groove coupled to the other of the inner cartridge or the outer cartridge and sized to receive the preload ring;
- and
- a preload element disposed within the annular groove and axially compressed between the preload ring and a preload surface of the annular groove such that said preload element maintains a simultaneous axial preload thrust on the inner cartridge and the outer cartridge in inwardly opposite axial directions.
An improved bearing system, comprising:
- a pair of cartridges comprising an inner cartridge slidably received by and aligned along a common axial center line with an outer cartridge, the inner and outer cartridges having respective bearing units configured to be mountable to a common axial shaft;
- a drain port formed in an annular relief in the outer cartridge for discharging excess oil from the bearing system to an oil discharge port in fluid communication therewith;
- and
- an annular lubricant bearing preload chamber formed between the inner cartridge and the outer cartridge such that pressurized lubricant in the bearing preload chamber axially separates the inner bearing cartridge from the outer bearing cartridge to form a simultaneous axial preload thrust on the inner cartridge and the outer cartridge in inwardly opposite axial directions.
