Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

A conical slope is provided on the end face of the shaft sleeve 9 close to the locking nut 2, and a fourth limiting boss 91 is provided on the outer side of the shaft sleeve 9, and a locking nut 2 is provided on the side of the shaft sleeve 9, and a conical slope is provided on the end face of the locking nut 2 close to the shaft sleeve 9, and a first limiting boss 21 is provided on the outer side of the locking nut 2; and a conical ferrule 8 is provided between the shaft sleeve 9 and the locking nut 2; specifically, a third limiting boss 81 is provided on the inner wall of the conical ferrule 8, and the third limiting boss 81 cooperates to connect the locking nut 2 and The conical slope surface of the sleeve 9, that is, the third limiting boss 81 is located between the locking nut 2 and the sleeve 9, and a limiting sleeve 4 is provided on the outer sides of the sleeve 9, the conical sleeve 8 and the locking nut 2, and a second limiting boss 42 is fixed to one end of the inner wall of the limiting sleeve 4; the fourth limiting boss 91 is connected to the second limiting boss 42; the fourth limiting boss 91 is used to limit the sleeve 9 when it is connected to the second limiting boss 42; and the outer wall of the limiting sleeve 4 is matched with the conical sleeve 8 by the third screw 41; the end of the limiting sleeve 4 is fixed to the end cover 3 by the second screw 31, and the end cover 3, the locking nut 2, the conical sleeve 8 and the sleeve 9 pass through the rotating shaft 6; the other side of the locking nut 2 is provided with a locking ring 1, and the locking ring 1 is fixed to the outer side of the rotating shaft 6.
[0023] The conical ferrule 8 adopts a segmented circular ring structure, and a plurality of limit blocks 43 are fixed to the inner wall of the limit sleeve 4; Figure 4 As shown, the stopper 43 is adapted to each segment gap of the conical ferrule 8. Exemplarily, the conical ferrule 8 is in three segments, and the stopper 43 is provided with three segments, and the three segments of the conical ferrule 8 are distributed in the stopper 43;
[0024] The inner ring of the locking nut 2 is provided with threads, the locking nut 2 is threadedly connected to the rotating shaft 6, and one end of the locking nut 2 is provided with a plurality of openings; the side of the locking nut 2 is provided with top screw holes, and each of the top screw holes is matched and connected with a top screw 7; the outer surface of the limiting sleeve 4 is matched with the conical ferrule 8 through a plurality of third screws 41 in an annular array, and the end surface of the limiting sleeve 4 is fixed to the end cover 3 through a plurality of second screws 31. The third screw 41 enters into the limiting sleeve 4 to achieve contact with the conical ferrule 8.
[0025] The locking ring 1 includes a first half ring 11, a second half ring 12 and a first screw 13. The first half ring 11 and the second half ring 12 both have a semicircular ring structure, and the first half ring 11 and the second half ring 12 are fixed by the first screw 13.
[0026] When the utility model is in use, first assemble the sleeve assembly consisting of the shaft sleeve 9, the tapered sleeve 8, the limiting sleeve 4 and the end cover 3, that is, insert the shaft sleeve 9 into the limiting sleeve 4, so that the fourth limiting boss 91 contacts the second limiting boss 42, and then place the tapered sleeve 8 in the limiting sleeve 4, so that each limiting block 43 is placed in the segmented gap of the tapered sleeve 8, and then penetrate to the outside of the rotating shaft 6, and connect the locking nut 2 with the rotating shaft 6 in a threaded manner, and make the other end of the locking nut 2 contact the third limiting boss 81, and then insert the third screw 41 to release the tapered sleeve 8, and tighten it into the locking nut 2 through the top screw 7 to fix it, and finally place the clamping ring 1 close to the locking nut 2, and use the first screw 13 to lock the first half ring 11 and the second half ring 12 to the rotating shaft 6, such as Figure 3 As shown. The setting of the top screw 7 and the clamping ring 1 can effectively prevent the locking nut 2 from loosening. Since the long roller shaft needs to go through a process from normal temperature to high temperature, during this process, the rotating shaft 6 will expand due to heat. After the rotating shaft 6 is heated to a stable temperature, a gap may be generated between the thread of the locking nut 2 and the tightening of the locking ring 1. At this time, the third screws 41 around the limit sleeve 4 can be tightened so that the third screws 41 squeeze the tapered sleeve 8 toward the center. Due to the matching relationship between the symmetrical tapered slope surface set on the inner ring of the tapered sleeve 8 and the tapered slope surface set on one side of the sleeve 9 and the locking nut 2, the tapered sleeve 8 will increase the distance between the sleeve 9 and the locking nut 2, thereby providing a gap caused by thermal expansion, so that the inner ring of the bearing is also subjected to axial extrusion force.
[0027] The utility model uses a variety of axial limiting structures to limit the inner ring of the bearing that cannot ensure the tolerance of the shaft hole, especially in the case of material expansion under high temperature environment, it can provide a certain amount of axial displacement compensation, so that the inner ring of the bearing is better positioned. The bearing limiting assembly provided by the utility model can effectively solve the problem that the inner ring of the bearing cannot be effectively limited under some special working conditions, thereby enabling the equipment to operate stably and efficiently according to the original design intention, increasing the stability of the equipment and the utilization rate of the equipment.
