Abstract
Parched elastohydrodynamic lubrication (EHL) film thickness in a space ball bearing is measured by electrical capacitance and resistance, and parched transients of oil film and lubricant breakdown are observed. With different oil-impregnated polymer retainers, which are employed as oil supply resources, parched degradation is restricted to some degree, even lubricant breakdown disappears and a steady state of the oil film is produced. A long-term space ball bearing demands both the lowest driving torque and a steady state oil film, which depends on a strictly controlled oil supply from oil-impregnated retainers. The results of this experimental research describe the effects of oil supply by amounts of oil in retainers on parched EHL.
