Description

Technical Field

[0001] The utility model relates to the field of bearing seats, in particular to a continuous casting type bearing seat. Background Art

[0002] Continuous casting is the abbreviation of Continuous Steel Casting. Compared with the traditional process of casting first and then rolling, this process of directly casting liquid steel into steel products through a continuous casting machine has greatly shortened the production time and improved work efficiency.

[0003] Continuous casting bearing is a special bearing, which is mainly used in steel machinery, especially in continuous casting equipment. This kind of bearing can bear large loads and has good high temperature resistance. However, if the bearing temperature is continuously increased in a high temperature environment, it will cause the bearing to be damaged and affect the normal rotation of the connecting shaft. The purpose of this utility model is to propose a new bearing seat to solve the above problems, so as to ensure the stable operation and service life of the bearing ring. Utility Model Content

[0004] The utility model aims to provide a continuous casting bearing seat to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a main body, a mounting seat, a support ring, a cover plate, a connecting pipe, a water inlet pipe and a water outlet pipe, the mounting seat is fixed to the bottom of the main body, an opening for accommodating a bearing and a connecting shaft is formed on the main body, the support ring is located in the opening and fixed to the main body, the support ring can abut against the inner side of the bearing, the cover plate is fixed to the main body and a through hole for the connecting shaft to pass through is formed in the center of the cover plate, the cover plate can abut against the bearing, the bearing and the connecting shaft separate the opening to form a first cooling chamber and a second cooling chamber, the connecting pipe is located in the main body and its two ends are respectively connected to the first cooling chamber and the second cooling chamber, one end of the water inlet pipe and the water outlet pipe are located outside and the other end is connected to the main body and is respectively connected to the first cooling chamber and the second cooling chamber.

[0006] In order to optimize the above technical solution, further measures are taken as follows: the diameters of adjacent support rings along the length direction of the connecting shaft gradually decrease and the diameter of the bearings supported by the support rings gradually decreases to match the support rings. This design is intended to ensure the strength of the main body and reduce the impact of the opening on the overall strength of the main body.

[0007] As a further improvement to the above technical solution: the diameters of adjacent cover plates gradually decrease along the length direction of the connecting shaft and the diameter of the bearings against which the cover plates rest gradually decrease to match the cover plates. The gradual design allows the cover plates to match the shapes of the bearings.

[0008] As a further improvement of the technical solution: the connecting pipe is located at the top of the main body and the water inlet pipe and the water outlet pipe are located at the bottom of the main body, ensuring that the cooling water can evenly dissipate heat to the bearing from bottom to top.

[0009] As an improvement to the above technical solution: bolts pass through the cover plate and are threadedly connected to the main body to achieve fixation of the cover plate and the main body, and the cover plate is fixed and disassembled conveniently by bolts.

[0010] Furthermore: the outermost cover plate surface is sprayed with a thermal insulation coating, and the purpose of setting the thermal insulation coating is to reduce heat transfer to prevent the cover plate from being heated rapidly. The thermal insulation coating belongs to the prior art content and the description is clear enough, so no further explanation is required.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a continuous casting bearing seat, which is provided with 3 bearings along the length direction of the connecting shaft, so as to ensure the stable rotation of the connecting shaft and avoid that a single bearing is damaged after being heated by a high temperature environment and affects the rotation of the connecting shaft. The bearings are circulated and cooled by cooling water and the bearings located on the outside can play a heat insulating role to ensure the stable operation of the bearings located on the inside and avoid that the high temperature environment affects the service life of the bearings.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-2 The utility model provides a continuous casting bearing seat, including a main body 1, a mounting seat 2, a support ring 3, a cover plate 4, a connecting pipe 5, an inlet pipe 6 and an outlet pipe 7. The mounting seat 2 is fixed to the bottom of the main body 1, and an opening 101 for accommodating a bearing and a connecting shaft is formed on the main body 1. The support ring 3 is located in the opening 101 and is fixed to the main body 1. The support ring 3 can abut against the inner side of the bearing. The diameters of adjacent support rings 3 gradually decrease along the length direction of the connecting shaft, and the diameter of the bearing abutted by the support ring 3 gradually decreases to match the support ring 3.

[0020] The cover plate 4 is fixed to the main body 1 and a through hole 401 is formed in the center of the cover plate 4 for the connecting shaft to pass through. Bolts pass through the cover plate 4 and are threadedly connected to the main body 1 to fix the cover plate 4 to the main body 1. The cover plate 4 can resist the bearing. The surface of the cover plate 4 located on the outermost side is sprayed with a heat-insulating coating. The diameters of adjacent cover plates 4 gradually decrease along the length direction of the connecting shaft and the diameter of the bearing resisted by the cover plate 4 gradually decreases to match the cover plate 4.

[0021] The bearing and the connecting shaft separate the opening 101 into a first cooling chamber 402 and a second cooling chamber 403. The connecting pipe 5 is located inside the main body 1 and is connected to the first cooling chamber 402 and the second cooling chamber 403 at both ends. One end of the water inlet pipe 6 and the water outlet pipe 7 are located outside and the other end is connected to the main body 1 and is connected to the first cooling chamber 402 and the second cooling chamber 403 respectively. The connecting pipe 5 is located at the top of the main body 1 and the water inlet pipe 6 and the water outlet pipe 7 are located at the bottom of the main body 1.

[0022] The water inlet pipe 6 and the water outlet pipe 7 refer to pipes for external cooling water to flow in and out. This description is clear enough, so the detailed structure and specific components of the water inlet pipe 6 and the water outlet pipe 7 are not further explained. The water inlet pipe 6 and the water outlet pipe 7 need to be connected to the external pipes respectively during implementation.

[0023] Working principle: The bearing seat is installed by bolting through the mounting seat 2 and fixing it to the mounting surface. During the rotation process, external cooling water is input from the water inlet pipe 6 and passes through the first cooling chamber 402, the connecting pipe 5, the second cooling chamber 403 in sequence, and finally leaves from the water outlet pipe 7. During the process, the cooling water can take away the heat of the bearing and the connecting shaft, avoiding the high temperature environment from affecting the stable operation of the bearing.

[0024] The first cooling chamber 402 and the second cooling chamber 403 have cooling water flowing therein to cool the three bearings disposed in the opening 101, ensuring stable operation of the bearings. Since the number of bearings disposed along the length direction of the connecting shaft on the bearing seat is 3, even if the outermost bearing is heated by a high temperature environment, the heat radiation received by the remaining bearings will be greatly reduced due to being blocked by the outermost bearing, and the flowing cooling water can ensure stable operation of the inner bearings, preventing the high temperature environment from affecting the service life of the bearings.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
