Bearing protector with slinger ring

摘要

A bearing protector employing a stator and a rotor defining a labyrinth therebetween and disposed for sealing cooperation between a housing and a rotatable shaft. The concentrically fit within one another due to relative axial movement therebetween, each is constructed as an integral continuous one-piece ring. The stator and rotor are axially secured in an assembled condition by a one-piece snap ring carried by the stator and which resiliently distorts to pass axially over the rotor and then resiliently snaps inwardly into a groove in the rotor so as to become fixed to and rotate with the rotor. This snap ring projects outwardly into a radially enlarged annular collecting chamber formed in the stator and acts, when the rotor rotates, as a slinger ring so that contaminates which enter into the labyrinth from the outside come into contact with the slinger ring and are thrown outwardly to the bottom of the collecting chamber for discharge through a drain.
