COATING SYSTEM AND METHOD FOR FACILITATING THE CLEANING OF A HYDRODYNAMIC BEARING AND A SECONDARY SEAL STRUCTURE MADE THEREBY

摘要

A coating system and method for facilitating the cleaning of hydrodynamic bearings and their associated structure is effectuated by applying a surface energy lowering coating to selected portions of the bearing other than the surface tension seal producing gaps thereof prior to a lubricant fluid fill. The coating system and method of the present invention may also advantageously be utilized to produce a secondary barrier seal extending a relatively short distance within and adjoining the opening of the surface tension seal producing gaps.
