Sealing structure for bearing lubrication

Abstract

The invention discloses a sealing structure for bearing lubrication. The sealing structure comprises a bearing pedestal used for installing a bearing and an outer baffle ring used for preventing lubricating grease from splashing outwards, the bearing pedestal is provided with at least two inner grease storage chambers distributed in the circumferential direction, and the outer baffle ring is provided with at least two outer grease storage chambers distributed in the circumferential direction; and rib plates are arranged between any two adjacent inner grease storage chambers and any two adjacent outer grease storage chambers, the rib plates in the bearing pedestal are provided with first through grooves used for allowing lubricating grease to enter the bearing, and the bearing pedestal is further provided with a grease injection port and a first grease injection channel communicating with the grease injection port and the first through grooves. The sealing structure for bearing lubrication can continuously supply base oil to a rolling bearing, so that the problem of poor lubrication of a large bearing in a high-speed motor is effectively solved, the service life of the bearing is favorably prolonged, and less maintenance and even no maintenance of the bearing are realized.

Description

technical field [0001] The invention relates to the technical field of bearing lubrication, in particular to a sealing structure for bearing lubrication. Background technique [0002] The bearing is an important part of the motor. It is mainly used to support the motor rotor to ensure its normal and stable high-speed rotation. The running state of the bearing directly affects the normal operation of the motor. Good lubrication of bearings needs to be guaranteed by proper lubrication and sealing configuration, especially for high-speed motors with grease-lubricated roller bearings. [0003] In the prior art, the inner and outer bearing caps of the bearing are respectively provided with inner and outer annular grease storage chambers. However, the grease in the annular grease storage chambers will be unstable due to the shearing and dragging effect of the bearing, and due to the annular The lubricating grease in the upper part of the grease storage chamber is prone to collaps...
