Bearing system

摘要

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.

1. 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.
