METHOD FOR PRODUCING BEARING HEMISPHERICAL CAVITIES

摘要

Method of manufacturing high-accuracy bearing for gas gyro using casting techniques. The bearing cavity is formed using a die or tool in the form of an accurately machined half sphere fastened to a flat baseplate. The baseplate is fitted with locating pins that locate the outer diameter of the housing half. The die used in said method is an aluminum alloy coated with a thin film of a silicone rubber coating.
