Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a combined sealed bearing seat. Background Art

[0002] The bearing seat is a large and extra-large bearing seat with special structure that can bear comprehensive loads. It has the characteristics of compact structure, flexible rotation, easy installation and maintenance, etc. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat.

[0003] After searching, the Chinese utility model patent with publication number: CN111043166A discloses a sealing structure of a bearing seat, including a sealing cover, a sealing ring, an adjusting sleeve, a sealing ring, a bearing, a bearing seat, an end cover and a ball. When in use, under the action of the ball, the sliding friction between the sealing cover and the sealing ring is changed into rolling friction, so that the sealing ring rotates more smoothly. The storage groove opened at the bottom of the slide groove can store the sealing oil injected into the slide groove. When the sealing ring rotates, it drives the ball to move synchronously, and the exposed part of the ball will be transferred into the storage groove and contact with the sealing oil inside the storage groove. The ball is lubricated by the oil stored in the storage groove, and the lubricated part is transferred out with the rotation of the sealing ring, and finally contacts with the inner wall of the slide groove opened on the sealing ring, which not only greatly reduces the friction between the sealing ring and the sealing cover, but also further improves the dustproof effect of the bearing.

[0004] From the analysis of the above technical solutions, it can be seen that in the current bearing seat, under the condition of a relatively harsh working environment, rainwater, dust, etc. will invade the bearing seat, and foreign matter can easily enter the interior of the bearing, affecting the operation of the bearing and reducing its service life.
