<p>PROBLEM TO BE SOLVED: To provide a cleaning method of a rolling bearing by which a high cleaning effect can be obtained even for the soil inserted in a shade of cleaning liquid or a space between parts which cleaning is difficult and a device constitution is easily simplified. SOLUTION: This cleaning method of a rolling bearing cleans the rolling bearing 1 which is constituted by providing an inner ring 1b, an outer ring 1a, plural rolling elements 1c and a holder by using the cleaning liquid 24, therein, the cleaning liquid 24 flows through the inside of the space where orbital surfaces of the inner ring 1b and the outer ring 1a of the bearing to be cleaned surround the rolling elements 1c and the holder from the axial direction of the bearing 1 to be cleaned. For example, a cylindrical rotor 2 having spiral grooves 2a is interposed in a flow passage for supplying the cleaning liquid, the cylindrical rotor 2 is rotated by the supply of the cleaning liquid 24 and the high-pressure cleaning liquid is supplied from the cylindrical rotor 2 into the bearing 1 to be cleaned.</p> |
