Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides an embodiment: a special self-aligning roller bearing for a roller press comprises a fixed block 3, a retainer 5 and an inner ring 4, wherein the retainer 5 is installed on the outer side of the inner ring 4, the fixed block 3 is uniformly arranged on two sides of the retainer 5, fixture blocks 7 are respectively arranged at two ends of the fixed block 3, a pocket hole 10 is respectively arranged between one end of the fixed block 3, rollers 2 are respectively installed in the pocket holes 10, clamping grooves 6 are respectively arranged at two ends of the rollers 2, the function of locking the rollers 2 is realized, so that the rollers are prevented from being unstably dropped, one end of each fixture block 7 is fixed in each clamping groove 6, the areas of the fixture blocks 7 and the clamping grooves 6 are equal, the clamping grooves 6 and the fixture blocks 7 are mutually cooperated to form a fixed structure, grooves 9 are respectively arranged on the inner walls of two ends of the fixed block 3, the lubrication is enhanced, the abrasion between the rollers 2 and the retainer 5 and the overload, the inner diameter grooves 8 are uniformly arranged below one side of the retainer 5, a stable lubricating oil film is formed between the retaining edge in the inner ring 4 and the inner surface of the retainer 5, the friction between the inner ring 4 and the retainer 5 is reduced, the rotating stability of the bearing is ensured, the oil grooves 11 are uniformly arranged on the outer wall of the retainer 5, and the central position of the oil groove 11 is provided with the oil hole 12, thereby realizing the full lubrication of the bearing, thereby reducing the heat generation of the bearing, the outer wall of the retainer 5 is uniformly provided with oil holes 12, the oil holes 12 extend to the inner wall of the retainer 5, the outer side of the retainer 5 is provided with an outer ring 1, one end of the inner ring 4 is provided with a bulge 15, and one end of the bulge 15 is provided with an installation block 13, bolt holes 14 are formed in two ends of the installation block 13, one end of the installation block 13 is meshed with one end of the inner ring 4 in shape, and two ends of the installation block 13 are fixed in the bolt holes 14 through bolts to lock the shaft.
