TESTING APPARATUS FOR BEARING SOLID LUBRICATED

摘要

A device for testing performance of a solid lubrication bearing is provided to measure the torque variation according to the number of rotation and to estimate the life of a test bearing. A device for testing performance of a solid lubrication bearing comprises: a chamber(110) in which a vent(1101) is formed at a lower part; a rotatable shaft(1201) extending to the inside from the top of the chamber; an inner wheel fixing member(1205) fixing an inner wheel of a test bearing to the vertical direction; a housing(130) in which an outer wheel of the test bearing; an outer wheel fixing member(1301) fixing an outer wheel to the vertical direction; an extension beam(1303) extending to the radial direction from a housing; a measuring unit(1305) contacting with the extension beam in a motor(120) rotation; a collecting duct(1103) extending from the vent to the test bearing; a connection pipe(1401) in which a pump is installed, extending from the vent; and a measuring unit(150) installed at the connection pipe.
