ANTIFRICTION BEARING Russian patent published in 2006 - IPC F16C19/22 F16C33/34 

FIELD: mechanical engineering; antifriction bearings.

SUBSTANCE: proposed antifriction bearing has races with hollow rolling elements arranged in cage in at least one row; cage consists of two washers connected by means of spacers mounted in hollow rolling elements. Inner surfaces of hollow rolling elements consist of at least three sections; one section used for locating by spacer is smoothly engageable with other sections adjoining it on side of hollow rolling element. Outer surface of spacer located between surfaces of cage washers directed to hollow rolling elements consists of two interconnected parts; one of them is used for locating hollow rolling element. Sections of inner surface of hollow rolling element and parts of outer surface of spacer are formed by any surfaces and are located towards each other. End face of cage washer directed away from hollow rolling elements is located in such position that spacer does not project beyond end face of cage washer; profile of cage washer section may be of any shape.

EFFECT: enhanced durability due to reliable locating of hollow rolling element by spacer.
