Frictional Characteristics of Water-Lubricated Compliant-Surface Stave Bearings

Abstract

Experimental friction data for full-complement water-lubricated stage bearings are presented and discussed. The test bearings are of similar construction to those used by the U.S. Navy for propulsion shaft support in outboard locations such as sterntube and strut bearings. Breakaway friction characteristics are compared for seven slave designs under a load of 280 kPa (40 psi). The duration of load was varied from 1 minute to almost 70 hours. Dynamic friction results are also presented for each stave design under loads of 70, 280 and 700 kPa (10, 40 and 100 psi, respectively) in incremental speeds up to 3.6 m/s (700 ft/min).
