Title: Rolling bearing
Inventor: FUKUDA KUNIO
IPC: F16C33/58
Filed: 2000-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a rolling bearing capable of effectively restraining the occurrence of fretting in spite of a relatively low cost. SOLUTION: Since lubricating oil oozes out of a solid lubricant A in an inner peripheral groove 10c to permeate and interpose between an inner peripheral surface of an inner race 10 and an outer peripheral surface of a rotary shaft 1, even if vibration is caused in a contact surface, the fretting can be effectively restrained by relieving bearing at that time. Particularly, since the fretting has a tendency of becoming remarkable in an end part area, the inner peripheral groove 10c is desirably extended to the both end vicinity of the inner race 10. The lubricating oil impregnated into the solid lubricant A can move along the inner peripheral groove 10c to a certain degree to restrain a malfunction such as lacking in lubrication only in a specific place.

Inventor: SUGIMOTO TOMOHIKO
IPC: F04B49/10
Filed: 2000-02-01
Abstract: PROBLEM TO BE SOLVED: To surely monitor the contamination state of a compressor with dust. SOLUTION: An efficiency computing element 19 calculates the efficiency ηof a compressor 3 in response to the outputs of the inlet and outlet temperature detectors 10 and 13 and inlet and outlet pressure detectors 11 and 14 of the compressor 3.
