Description

Technical Field

[0001] The utility model belongs to the technical field of damping gaskets, and specifically relates to a damping gasket for a finishing mill. Background Art

[0002] Morgan's fifth-generation finishing mill is a high-speed, heavy-load equipment. The impact load on the roller bearings during operation is extremely large, and the damping gasket is an important component in the equipment to protect the bearings from impact. As the rolling speed of high-speed wire production increases, the performance requirements for the damping gaskets used to protect the roller bearings are also increasing.

[0003] Existing damping gaskets generally have two symmetrical upper damping gaskets and lower damping gaskets. Both gaskets are annular and overlap each other. Elastomers can be set on the opposite surfaces to increase the load-bearing performance and improve the damping elastic buffer. However, the elastomer of the composite structure damping gasket is generally bonded together. After the damping wear, the elastomer is prone to displacement and falling off. The composite structure has poor durability and also reduces the safety and reliability of the damping gasket. Utility Model Content

[0004] The utility model aims to provide a damping gasket for a finishing mill unit which has a stable and reliable composite structure, good bearing capacity and elastic damping performance, and has the characteristics of simple structure, economy and durability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A damping gasket for a finishing mill comprises an upper ring sheet and a lower ring sheet which are stacked and bonded together by an elastic layer. The invention is characterized in that a plurality of annular grooves are arranged on the bottom surface of the upper ring sheet and / or the top surface of the lower ring sheet, and ribs are arranged on the inner and outer sides of the annular band cross section of the upper ring sheet and the lower ring sheet respectively, and the ribs are used to limit the elastic layer.

[0007] Additional technical features constituting the above-mentioned damping gasket for a finishing mill also include:

[0008] The elastic layer is made of rubber or plastic, and a plurality of reinforcing layers are stacked in the elastic layer at intervals, and the reinforcing layers are steel plates, steel meshes and / or fiber layers;

[0009] - A permanent magnet ring is arranged in the annular groove, and the magnetic poles of the permanent magnet ring located on the bottom surface of the upper ring piece and the permanent magnet ring located on the top surface of the lower ring piece are opposite to each other.

[0010] Compared with the prior art, the damping gasket for a finishing mill provided by the utility model has the following advantages: the upper ring sheet and the lower ring sheet of the damping gasket are bonded together by an elastic layer, and a plurality of annular grooves are arranged on the bottom surface of the upper ring sheet and / or the top surface of the lower ring sheet, the concave-convex interface increases the contact area with the elastic layer, and improves the bonding connection strength, and at the same time, the annular groove has a snap-fitting and positioning effect on the elastic layer, preventing the elastic layer from being deformed, displaced, and other problems due to load-bearing during use of the damping gasket; and, ribs are respectively arranged on the inner and outer sides of the annular band cross section of the upper ring sheet and the lower ring sheet, and the ribs are used to limit the elastic layer, which further enhances the composite structural strength of the damping gasket, facilitates production and installation, is safer and more reliable to use, and has the advantages of simple and compact structure, economy and durability.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0014] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set / provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0015] like Figure 1As shown, the structure of the novel finishing mill damping gasket comprises an upper ring sheet 1 and a lower ring sheet 2 which are stacked and bonded together by an elastic layer 3. A plurality of annular grooves 4 are arranged on the bottom surface of the upper ring sheet 1 and / or the top surface of the lower ring sheet 2. Ribs (5, 5') are arranged on the inner and outer sides of the annular band cross section of the upper ring sheet 1 and the lower ring sheet 2, respectively, and the ribs (5, 5') are used to limit the elastic layer 3.

[0016] The working principle is as follows: the upper ring piece 1 and the lower ring piece 2 of the novel damping gasket are bonded into an integral structure through an elastic layer 3, a plurality of annular grooves 4 are arranged on the bottom surface of the upper ring piece 1 and / or the top surface of the lower ring piece 2, and the formed concave-convex structure surface increases the contact area with the elastic layer 3, making the bonding more reliable, and retaining edges (5, 5') are respectively arranged on the inner and outer sides of the annular band cross section of the upper ring piece 1 and the lower ring piece 2, which can effectively position the elastic layer 3, thereby improving the elastic bearing performance of the damping gasket and the overall strength of the composite structure.

[0017] In the structure constituting the damping gasket of the above-mentioned novel finishing mill,

[0018] ——Preferably, the elastic layer 3 is made of rubber or plastic, and a plurality of reinforcing layers 6 are stacked in the elastic layer 3 at intervals. The reinforcing layers 6 are steel plates, steel meshes and / or fiber layers. The rubber constituting the elastic layer 3 can be made of a variety of materials, such as polyurethane rubber, nitrile rubber or EPDM rubber, as long as it has high elastic damping hardness, axial load-bearing rigidity, good wear resistance and bonding properties. The reinforcing layers 6 help to increase the elastic strength of the damping gasket, improve the load bearing capacity, avoid the problem of elastic fatigue damage and breakage of the steel ring, and make it safer, more reliable and more durable;

[0019] ——As a preferred embodiment, a permanent magnet ring (7, 7') is arranged in the above-mentioned annular groove 4, and the magnetic poles of the permanent magnet ring 7 located on the bottom surface of the upper ring piece 1 and the permanent magnet ring 7' located on the top surface of the lower ring piece 2 are opposite to each other. The permanent magnet is preferably a nephrite magnet structure, that is, a magnetic damping mechanism is formed between the upper ring piece 1 and the lower ring piece 2, which further enhances the elastic buffering effect inside the damping gasket, and also improves the axial bearing performance and elastic stiffness of the annular gasket, strengthens the protection of the elastic layer 3, avoids excessive wear, and extends the service life.
