Abstract
A bearing with one or more layers of lubricated spacers for dynamically brace-supporting first and second slide surfaces independently movable relative to each other. The spacers are positioned between the first and second slide surfaces, and each spacer has a pair of opposing spacer slide surfaces which are adapted to slide in surface-to-surface contact relative to an adjacent slide surface. Lubricants are used to facilitate low friction relative sliding motion between the slide surfaces, which can be either bonded to the spacers, or separately deposited between the slide surfaces.
Claims1
A method for rotatingly and longitudinally supporting a shaft in a stationary member, said shaft having a longitudinal axis, comprising the steps of:
- forming a frusto-conical step in said shaft to provide an enlarged shaft length, a frusto-conical length and a reduced shaft length, said frusto-conical length having a shaft frnsto-coiijcal angle with respect to the longitudinal axis of said shaft;
- a forming a frusto-conical support surface in a stationary member, said frusto-conical support surface having a support frusto-conical angle equal to said shaft frnsto-conical angle;
- placing at least two frusto-conical spacers comprising bearing members between said frusto-conical step in said shaft and said frusto-onical support surface in said stationary member, said spacers having a spacer frusto-conical angle equal to said shaft frusto-conical angle and said support frusto-conical angle, said at least two frusto-conical spacers having a central opening larger than an outside diameter of said reduced shaft length, said at least two frusto-spacers each having a pair of opposing spacer slide surfaces;
- and
- providing means for reducing friction between said slide surfaces whercby said reduced shaft length is supported to permit rotation and to support longitudinal pressure in the direction of said central opening of said spacers.
