Technical Field

[0001] This utility model belongs to the field of processing equipment, and in particular relates to a fixing device for a layer-cooled roller conveyor bearing. Background Technology

[0002] In recent years, my country's steel product market has undergone significant changes. A few years ago, the hot-rolled strip steel market, especially the medium and narrow strip market, was exceptionally hot, and demand for medium and narrow strip steel surged. Laminar flow roller conveyors are used to transport steel strips to the next coiling process, and their proper operation is crucial to strip quality and production rhythm. However, laminar flow water entering the roller conveyor can cause insufficient bearing lubrication, leading to roller conveyor stoppage and affecting strip surface quality and production rhythm.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] A laminar cooling roller conveyor bearing fixing device, comprising:

[0028] The fixed base 1 has a placement groove corresponding to the bearing, and a first rotating hole corresponding to the roller is opened at the bottom of the placement groove. A sealing element 3 is provided in the first rotating hole. The inner sleeve of the bearing is fixedly connected to the roller, and the outer sleeve of the bearing is fixedly connected to the fixed base 1.

[0029] End cap 2 is located at the top of the placement groove. The end cap 2 has a second rotating hole corresponding to the roller. The end cap 2 and the placement groove cooperate to fix the bearing in the fixed seat 1. The roller passes through the first rotating hole and the second rotating hole.

[0030] The placement groove is located at the end of the fixed seat 1 away from the roller to prevent cold water from entering the bearing through the end cover 2.

[0031] The first rotating hole has a drainage groove 101 at the end away from the fixed base 1. The drainage groove 101 has multiple drainage holes on its side wall. All the drainage holes are opened along the direction of gravity, and the sealing member 3 is disposed in the drainage groove 101.

[0032] The sealing element 3 is a tubular structure. The inner wall of the sealing element 3 has multiple through holes 301 corresponding to the drainage holes, and the through holes 301 are connected to the drainage holes.

[0033] The inner wall of the sealing element 3 has a guide groove 302 corresponding to the through hole 301. The bottom surface of the guide groove 302 is arc-shaped, and the multiple through holes 301 are all connected to the through hole 301.

[0034] The inner wall of the seal 3 is a conical structure. The inner diameter of the seal 3 at one end near the roll is larger than the inner diameter at the other end. Due to the influence of gravity, the cooling water is difficult to flow backward to the rotating shaft. Furthermore, the cooling water will flow away from the bearing under the action of gravity.

[0035] Stabilizing rings 303 are fixed at both ends of the sealing element 3, and the inner wall of the stabilizing rings 303 is in contact with the roll.

[0036] Furthermore, a sealing ring is provided between the end face of the stabilizing ring 303 away from the sealing element 3 and between the two adjacent through holes 301. The inner wall of the sealing ring is pressed against the side wall of the roll. The multi-stage sealing ensures that the layer of cold water will not enter the bearing. After each layer of cold water seeps into a layer, it will flow out under the action of the guide groove 302 and the drain hole. Even if a few layers of cold water enter the next layer, they will flow out in the next layer.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
