Self-power generation cooling bearing

Abstract

The invention discloses a self-power generation cooling bearing, and belongs to the technical field of bearings. The self-power generation cooling bearing comprises an inner ring, an outer ring, a rolling body and a retainer, wherein a power generation device and a plurality of cooling devices are arranged between the inner ring and the outer ring; the power generation device comprises a primary coil or a secondary coil arranged on the inner ring and a secondary coil and a primary coil arranged on the outer ring; the secondary coil and the primary coil are aligned with the width of the inner ring or the outer ring; the cooling devices are uniformly distributed on the circumference of the outer circle surface of the inner ring or the circumference of the inner circle surface of the outer ring; the cooling devices are electrically connected with the secondary coil. According to the self-power generation cooling bearing, one or more linear motors can be formed through the primary coil andthe secondary coil arranged between the inner ring and the outer ring, energy is provided for the cooling devices, and the operating temperature of the bearing during rolling is effectively reduced,so that the abrasion is reduced, the service life is prolonged, and compared with the prior art, the self-power generation cooling bearing has the advantages of simple structure, low using cost and long service life.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a rolling bearing which can provide cooling energy during its motion. Background technique [0002] Rolling bearing is a kind of kinematic pair, which is used to support the rotating shaft and the parts on the shaft, and maintain the normal working position and rotation accuracy of the shaft. It is of great significance to reduce the friction coefficient between mechanical parts during motion and improve the service life. However, rolling bearings inevitably have frictional heat generation during high-speed rotation, which accelerates aging and causes the problem of low service life. [0003] In view of the above problems, the existing technology adopts methods such as oil bath lubrication, oil drop lubrication, oil mist lubrication, oil spray lubrication and pressure oil supply lubrication to cool down and reduce the friction coefficient to improve the service life...
