Add cumbersome, and internally easily accumulate some dusts, influence the rotating effect of bearing.
The content of the invention
The purpose of this utility model is to provide a kind of bearing, with adding for the lubricating oil that solves to propose in above-mentioned background technology
Add it is cumbersome, and the problems such as internally easily accumulate some dusts.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of bearing, bag
Bearing main body and connector are included, one end of the connector is fixedly connected with bearing main body, and the side of the bearing main body is provided with
Inner ring body, the side of the bearing main body are provided with outer ring, and the side of the inner ring body is socketed with inner ring, the inner ring and outer ring it
Between be provided with steel ball, the madial wall of the connector is provided with grease groove, and the both sides of the steel ball are provided with retainer, the inner ring with
Side between outer ring close to retainer is provided with sealed groove, and the side of the outer ring is connected with dust-proof port.
Preferably, the inner ring forms raceway with outer ring, and the size of the steel ball is 44.5mm, the inner ring and outer ring structure
Curvature into raceway is 23.11mm.
Preferably, the side of the sealed groove is provided with seal bead.
Preferably, the inside of the seal bead is provided with lubricating oil cavity.
Preferably, the surface of the grease groove scribbles corrosion-resistant member, and the sealed groove is provided with two, and seals recessed
Groove is symmetrical.
Preferably, the sealed groove is interference fitted with seal bead.
The utility model has the advantage that：This kind of bearing arrangement is simple, compact and reasonable, by provided with grease
Groove, and one end of grease groove extends to inner ring and formed with outer ring on raceway, and the storage grease in grease groove is in thermal histories
In slowly flowing on inner ring and outer ring composition raceway, it is more lubricated, reduce the resistance of friction, rotating effect is more preferable,
By being provided with lubricating oil cavity in the inside of seal bead, lubricating oil can be stored so that operation is more convenient, dust-proof
Port effectively avoids the entrance of dust, the service life of extension device to dust.
