Description

Technical Field

[0001] The utility model belongs to the technical field of throw rings, and particularly relates to a throw ring for improving the service life of a taper sleeve of a roll box. Background Technique

[0002] There are requirements for the elevation of the roll ring of the existing roll box. In order to ensure the height of the roll ring, as Figure 6 shown, it is necessary to add a spacer ring to the existing roll box equipment to ensure the elevation of the roll ring.

[0003] The current equipment design has the following problems: the coaxiality of the roll ring and the spacer ring is positioned by the taper sleeve. Therefore, the expansion length of the taper sleeve in use must be designed to exceed the thickness of the roll ring, which greatly reduces the service life of the taper sleeve (the working principle of the taper sleeve is: by pressing the upper end face of the taper sleeve, the outer circle of the taper sleeve expands under the action of the conical surface to fasten the roll ring. The material of the taper sleeve has a certain expansion coefficient).

[0004] Explanation of this problem defect: when the outer circle of the taper sleeve is protected by the roll ring when the taper sleeve expands under force, the expansion amount of the outer circle of the taper sleeve is within a controllable range (the gasket cannot play a protective role). After the pressure is relieved, the outer circle size will rebound. On the contrary, when there is no roll ring size protection, the expansion amount is uncontrollable, resulting in an increase in the size of the outer leakage part, which causes great difficulties in disassembling and assembling the roll ring. Sometimes the interference amount is very large and the roll ring cannot be disassembled and assembled normally, resulting in a sharp reduction in the service life of the taper sleeve.

[0005] There are some hazards in actual use. For example:

[0006] 1. After the size of the taper sleeve exceeds the tolerance, it will cause difficulties in disassembly and assembly, and seriously affect the production progress;

[0007] 2. When the roll ring is stuck on the taper sleeve, the elevation of the roll ring assembly is not in place. If it is not detected, it will cause the roll box to enter water, or the roll ring and the roll shaft are not concentric, increasing the vibration value of the equipment and affecting the precision processing of the equipment production;

[0008] 3. The contact area between the roll ring and the taper sleeve is reduced, resulting in misalignment of the roll ring during production, producing defective products, and seriously running steel or exploding the roll ring. Content of the Utility Model

[0009] To solve the problems raised in the above background technique. The utility model provides a throw ring for improving the service life of a taper sleeve of a roll box, which has the characteristics of improving the service life of the taper sleeve of the roll box, the production safety on the roll box line and the maintenance efficiency.

[0010] To achieve the above object, the utility model provides the following technical solution: a throw ring for improving the service life of a taper sleeve of a roll box, including an outer throw ring and an inner throw ring arranged below the outer throw ring. Among them, the upper end of the outer throw ring includes an integrally formed spacing portion.

[0011] In order to cooperate with the lip seal ring to achieve sealing, further, a first sealing cavity is provided on the outer side of the top of the inner throw oil ring. A second sealing cavity corresponding to the first sealing cavity is provided on the outer side of the bottom surface of the outer throw oil ring.

[0012] In order to achieve the seal between the inner throw oil ring and the roller shaft, further, a first ring groove is provided on the inner side of the inner throw oil ring. A first O-ring is provided inside the first ring groove.

[0013] In order to achieve the seal between the outer throw oil ring and the roller shaft, further, a second ring groove is provided on the inner side of the outer throw oil ring. A second O-ring is provided inside the second ring groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, a fixed-distance part is integrally formed at the upper end of the outer throw oil ring. Compared with the split structure of the outer throw oil ring and the fixed-distance ring in the prior art, the assembly structure is simplified, the probability of water ingress into the roller box caused by poor contact of accessories during use is reduced, the design defect of the coaxiality of the taper sleeve positioning the fixed-distance ring can be avoided, direct positioning by using the coaxiality of the outer throw oil ring is realized, the problems of difficult disassembly and short service life of the taper sleeve are solved, the maintenance and repair time of workers is reduced, and the service life of the whole machine is improved.
