Abstract
A rotor bearing assembly is provided wherein a shaft is journalled within a housing by a pair of spaced bearings packed in a quantity of grease. An oil guide surrounds the shaft and a storage space between the guide and the housing is formed for retaining a supply of grease capable of releasing oil into the guide to replenish the packing. A fresh supply of grease is periodically introduced into the storage space through an inlet extending through the housing. An outlet extends through the housing for discharging a corresponding quantity of grease from the storage space into a collection chamber exterior of the housing which receives and holds the discharged grease.
Claims2
In a rotor bearing assembly having a shaft journalled within a housing by a pair of spaced bearings and having an oil guide surrounding said shaft, said housing and said oil guide defining a storage space for retaining a supply of grease and being capable of releasing oil into said oil guide, the improvement comprising means for selectively replenishing the storage space with a fresh supply of grease comprising an inlet extending radially through said housing into said storage space for the introducing of fresh grease thereto, an outlet through said housing for discharging a quantity of grease from said storage space and a tubular casing surrounding and spaced from said housing to define a collection chamber exterior of said housing for receiving said discharged grease, said casing being supported by a pair of axially spaced elastic support rings sealing the ends of said collection chamber.
