[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-4 The utility model embodiment is a reinforced rolling mill bearing, which includes an outer ring body 1 and an inner ring body 2. The middle surface of the outer side of the inner ring body 2 is provided with a contact groove 8, and a rolling body 4 is provided inside the contact groove 8. Retaining rings 5 are provided on both sides of the outer surface of the rolling body 4, and a limiting ring 6 is provided on one side of the outer surface of the retaining ring 5. Sealing rings 3 are provided on both end surfaces of the outer side of the inner ring body 2, and limiting grooves 7 are provided on both sides of the inner surface of the outer ring body 1.
[0023] The inner ring body 2 is usually made of high-strength, wear-resistant alloy steel. The middle outer surface of the inner ring body 2 is recessed and connected with the contact groove 8. The connection between the contact groove 8 and the middle outer surface of the inner ring body 2 forms an annular structure. There are several rolling bodies 4. The several rolling bodies 4 are all spherical high-carbon chromium steel. The surface is hardened. The several rolling bodies 4 are in contact with the inside of the contact groove 8. The rolling bodies 4 are made of high-carbon chromium steel and the surface is hardened. During the rolling process between the inner ring body 2 and the outer ring body 1, friction and load transfer are reduced. Two retaining rings 5 are provided. The two retaining rings 5 are made of metal or other wear-resistant materials. The two retaining rings 5 form a fixed contact effect through the limited contact on the surfaces on both sides of the rolling body 4. The retaining rings 5 are used to maintain the orderly arrangement of the rolling bodies 4 to prevent When the inner ring 2 is in a state of being ...
[0024] Working principle: When the reinforced rolling mill bearing is working, the rolling element 4 rolls between the inner ring 2 and the outer ring 1, thereby realizing the force transmission and motion guidance between the working roll and the rolling mill frame. At the same time, the sealing ring 3 prevents the lubricant left between the rolling elements 4 from leaking out of the bearing body. Adequate grease can reduce wear and keep the bearing in good working condition.
