Lubricating rotor bearings in open end spinning machines

摘要

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.
