POLYMERIC BEARING ARTICLES FOR USE IN ULTRA-HIGH PRESSURE AND VELOCITY ENVIRONMENTS |
摘要 |
A polymeric thrust bearing is provided for an ultra-high PV environment. The polymeric thrust bearing includes an annular bearing body having an inner perimeter and an outer perimeter, and a plurality of lubricant channels extending across the annular bearing body from the inner perimeter to the outer perimeter. The annular bearing body comprises a polymer composition comprising a polymer having typically a glass transition temperature of at least about 140° C., such as an aromatic polyimide or a poly(aryl ether ketone), and at least one friction and wear additive. The polymeric thrust bearing is configured to withstand a velocity and a pressure in a lubricated environment in which the product of the velocity and the pressure is about 1,100,000 psi-fpm (23540 kg/cm2×m/min) or more. |
