摘要： A protective coating is applied to an inner or an outer member of a rotary fluid bearing by sputtering to minimize scuffing, wear and premature failure of the members during starts and stops of the bearing. The coating may include titanium, tungsten, chromium, amorphous carbon with or without metallic impurities, and hydrogenated amorphous carbon with or without metallic impurities. One of the members is formed in two sections to accommodate assembly of the bearing and these sections abut at end faces. Features on each end face are imparted to the other end face in a compression coining process to facilitate rapid and repeatable alignment of the two sections when separated and rejoined during subsequent manufacturing steps.

摘要： A full complement antifriction bearing includes an inner race, an outer race, and rolling elements organized in a circular row between the races without a cage or retainer for separating the rolling elements. While the absence of a cage or retainers enable the bearing to have the maximum number of rolling elements and thus transfer greater loads, adjacent rolling elements contact each other. Each rolling element or every other rolling element is covered with a tribological coating that retards adhesive wear and reduces friction.

摘要： Engineered surface treatments are applied to different types of hydraulic motors and pumps to improve the life of the contacting surfaces in said motors and pumps. The engineered surface treatments are selected from texture modifications and tribiological coatings and selectively applied to one or both of the contacting surfaces to reduce friction and improve fatigue life under poor lubrication operating conditions.
