Abstract
A supporting pivot thrust bearing apparatus is provided in which a steel ball groove is formed at both ends of a rotary shaft inserted into a through hole of a sleeve, and a steel ball is fixably inserted between the steel ball groove and a thrust support. The steel ball is in contact with the steel ball groove by line contact so that lateral of the steel ball can be prevented. As a result, eccentricity between a center shaft of the steel ball and a center shaft of the rotary shaft can be prevented, thereby improving rotative stabilization of the rotary shaft.
Claims8
A supporting pivot thrust bearing apparatus comprising:
- a pair of sleeves mounted into a pair of bearing brackets, having through holes therein;
- a rotary shaft inserted into the through holes of said pair of sleeves, having two ends and a kinetic pressure generating groove on an external side which faces an internal side of the respective through hole;
- a pair of thrust supports mounted into said pair of bearing brackets;
- a steel ball inserted between both ends of said rotary shaft and said pair of thrust supports;
- and
- a position fixing means formed at both ends of said rotary shaft and in contact with said steel ball to prevent lateral motion of said steel ball.
