Low friction seal for bearings

摘要

A bearing assembly includes an annular inner member defining a first outer surface and a first inner surface, and a shaft extending therefrom. The bearing assembly includes an annular outer member defining a second outer surface and a second inner surface which is adapted to engage a recess defined in the first outer surface. An annular flexible seal defines a base adapted to engage the outer member, a head adapted to engage a groove defined in one of the inner member or the shaft, and a neck having a curvilinear cross-section which is adapted to bias the base toward the recess and the head toward the groove. The flexible seal is positioned adjacent to one end of the outer member and extends between the inner member and outer member. An annular low-friction liner has a cross-section that defines an interior area adapted to engage the flexible seal head.

主权项

1. A method for installing a sealing system for a bearing comprising:
providing an inner member defining an outer surface and having a shaft extending therefrom, the shaft defining a groove therein; providing an outer member defining an inner surface adapted to engage the inner member outer surface; providing a flexible seal defining a base adapted to engage a recess defined in the inner surface of the outer member, a head adapted to engage the groove, and a neck having a curvilinear cross-section, the neck being adapted to bias the base toward the recess and the head toward the groove; providing a low-friction liner having a cross-section defining an interior area adapted to engage the flexible seal head; dividing the low-friction liner into at least two liner segments wherein each liner segment defines at least one transverse face; displacing the liner segments away from each other; disposing the low-friction liner on one of the groove or the flexible seal head by engaging the liner segment transverse faces with one another; positioning the flexible seal base adjacent to one end of the outer member extending between the inner member and the outer member; and positioning the flexible seal head in the groove.
