Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and particularly relates to a rolling bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Existing bearings are generally composed of an outer ring, a sealing ring and an inner ring, and the sealing ring is generally composed of a rubber body and a frame. However, the equipment may be used in places with poor environments. Traditional sealing rings are difficult to withstand the erosion of impurities for a long time, which can easily cause damage to the sealing rings, thereby affecting the service life of the bearings and even causing the equipment to stop working. In addition, the sealing gaskets are extremely troublesome to remove, and the staff need to remove them by force, which can easily damage the sealing gaskets, increase the cost of use, and bring unnecessary trouble to the staff.

[0005] In the above rolling bearing, a fixing portion is provided on the fixing collar, the lower end of the upper bearing inner ring is in contact with the upper end of the fixing portion, and the upper end of the lower bearing inner ring is in contact with the lower end of the fixing portion.

[0006] In the above-mentioned rolling bearing, the upper bearing inner ring is provided with a sliding groove 1 for the balls to slide, the lower bearing inner ring is provided with a sliding groove 2 for the balls to slide, and the bearing outer ring is provided with a sliding groove 3 for the balls to slide, and the sliding groove 1 and the sliding groove 2 are combined to be the same as the sliding groove 3.

[0007] Compared with the prior art, the present rolling bearing has a sealing effect enhanced by connecting rings fixedly arranged on the two bearing inner rings corresponding to the convex rings on the bearing outer rings. Since the bearing inner rings are of a split structure, it is convenient for the staff to install the various parts of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS
