Description

Technical Field

[0001] This utility model belongs to the field of steel rolling technology, and in particular relates to a roll system installation structure that is easy to maintain. Background Technology

[0002] In the steel rolling process, roller systems are frequently used to transport steel billets. Current roller system installation structures have the following problems during use: First, the drive shaft is connected to the roller system via a coupling, which limits the movement of the bushings on the roller system. When maintenance or repair is required on the drive shaft side, disassembling the coupling can cause the bushings to lose their limiting position and become loose, affecting subsequent installation. Second, the side of the bearing closest to the rotating roller lacks protection. During the spray cooling process, water can flow into the bearing, affecting its service life. Furthermore, surface oxide debris generated during billet transportation may also damage the sealing rings and enter the bearing's interior, further impacting its service life. Utility Model Content

The diameter of the mounting column 202 is smaller than the inner diameter of the outer ring of the bearing 5, and the diameter of the mounting column 202 is larger than the diameter of the rotating column 203.

[0054] The bearing housing 3 is provided with a first through ring 7 at one end near the rotating roller 2. The end face of the first through ring 7 near the bearing housing 3 is fixed with a first annular boss 701 that matches the bearing housing 3.

The second annular boss 801 is installed on the inner side of the bearing housing 3 and presses against the outer ring of the bearing 5 near the coupling 1.

[0056] The first through ring 7 and the second through ring 8 are detachably connected to the bearing housing 3 by mounting bolts 11. The first through ring 7 and the second through ring 8 serve to axially position the bearing 5.

[0057] The first through ring 7 is provided with a first pressure ring at one end near the rotating roller 2. The first through ring 7 is provided with a first sealing groove on the inner side of the end near the first pressure ring. A J-shaped sealing ring 12 is provided on the inner side of the first sealing groove. The J-shaped sealing ring 12 is located on the outer side of the mounting post 202. The first pressure ring presses the J-shaped sealing ring 12 in the first sealing groove.

[0058] The second through ring 8 is provided with a second pressure ring 10 at one end near the coupling 1. A second sealing groove is opened on the inner side of the second through ring 8 near the second pressure ring 10. A J-shaped sealing ring 12 is provided on the inner side of the second sealing groove. The J-shaped sealing ring 12 is located on the outer side of the bushing 15. The second pressure ring 10 presses the J-shaped sealing ring 12 in the second sealing groove.

[0059] The first pressure ring and the second pressure ring 10 are detachably connected to the bearing housing 3 by mounting bolts 11 (the connection structure of the mounting bolts 11 is as follows: the bearing housing 3, the first through ring 7, the second through ring 8, the first pressure ring, and the second pressure ring 10 have corresponding through holes. The mounting bolts 11 pass through the through holes of the second pressure ring 10, the second through ring 8, the bearing housing 3, the first through ring 7, and the first pressure ring in sequence and are then threadedly connected to the nut). The J-shaped sealing ring 12 improves the sealing performance between the first through ring 7 and the mounting post 202, as well as the sealing performance between the second through ring 8 and the bushing 15.

[0060] The first venting ring 7 has a first vent hole 702 corresponding to the ball bearing 5, and the first pressure ring has a second vent hole 903 communicating with the first vent hole 702. The first vent hole 702 and the second vent hole 903 play the role of venting and preventing the air pressure inside the bearing 5 from being too high.

[0061] A water-blocking pipe is fixedly provided at one end of the first pressure ring near the rotating roller 2, and an annular water-blocking plate is provided on the inner side of the end of the water-blocking pipe near the rotating roller 2; the annular water-blocking plate and the water-blocking pipe can prevent liquid or debris from falling directly onto the surface of the mounting column 202, thus playing a protective role.

[0062] An annular centrifugal boss 201 is fixed on the outside of the mounting column 202. The annular centrifugal boss 201 is located between the first baffle and the annular water baffle. The annular centrifugal boss 201 plays a role in water isolation, preventing liquid from moving towards the bearing 5, and causing liquid and debris to move in all directions under the action of centrifugal force. There is a gap between the annular water baffle and the mounting column 202. The lower end of the annular water baffle is provided with a drain hole 904, which facilitates the discharge of liquid inside the water baffle pipe.

[0063] In some embodiments, the first pressure ring is an integral structure, and the water-blocking pipe and the annular water-blocking plate are welded together and then fixed to the first pressure ring.

[0064] In other embodiments, the first pressure ring includes two arc-shaped pressure plates 9, which together form the first pressure ring. Each arc-shaped pressure plate 9 is provided with an arc-shaped water baffle 901. A semi-circular water baffle 902 is provided on the inner side of one end of the rotating roller 2 of the arc-shaped water baffle 901. The inner diameter of the arc-shaped water baffle 901 of the upper arc-shaped pressure plate 9 is larger than the outer diameter of the arc-shaped water baffle 901 of the lower arc-shaped pressure plate 9. The arc-shaped pressure plates 9 form the first pressure ring.

Furthermore, the inner diameter of the arc-shaped baffle 901 of the upper arc-shaped pressure plate 9 is larger than the outer diameter of the arc-shaped baffle 901 of the lower arc-shaped pressure plate 9. Under the action of the centrifugal force of the mounting column 202, the liquid and debris move towards the inner wall of the arc-shaped baffle 901. The liquid and debris of the arc-shaped baffle 901 of the upper arc-shaped pressure plate 9 flow out in the gap between the upper and lower arc-shaped baffles 901, and the liquid and debris of the arc-shaped baffle 901 of the lower arc-shaped pressure plate 9 flow out through the drain hole 904.

[0065] A second sealing ring 14 is provided between the root of the first annular boss 701 and the second annular boss 801 and the inner side of the bearing housing 3; a sealing gasket 13 is provided between the second through ring 8 and the bearing housing 3. The second sealing ring 14 and the sealing gasket 13 improve the sealing performance between the first through ring 7, the second through ring 8 and the bearing housing 3.

[0066] The inner diameter of the arc-shaped plate 4 matches the diameter of the annular mounting groove 205, and the outer diameter of the arc-shaped plate 4 is larger than the outer diameter of the bushing 15. Ear plates 401 are fixed at both ends of the arc-shaped plate 4, and mounting holes are opened on the ear plates 401. Connecting bolts pass through the mounting holes and are threadedly connected to nuts. The two arc-shaped plates 4 are detachably connected by connecting bolts. The arc-shaped plate 4 can be disassembled using the connecting bolts. Even after disassembling the coupling 1, the arc-shaped plate 4 can still limit the bushing 15, preventing it from slipping off and facilitating the maintenance of the roller system.

[0067] Work process:

[0068] The process of installing the rotating roller 2 is as follows:

[0069] A first pressure ring and a first through ring 7 are sequentially fitted onto the outer side of the mounting post 202 near the end of the rotating roller 2 adjacent to the coupling 1. Then, a bearing 5 is fitted onto the outer side of the rotating post 203, with the inner ring of the bearing 5 interference-fitted to the rotating post 203. A bearing seat 5 is installed on the outer side of the bearing 5, with the outer ring of the bearing 5 interference-fitted to the bearing seat. A bushing 15 is then installed on the outer side of the connecting post 204. A second through ring 8 and a second pressure ring 10 are sequentially installed on the outer side of the bushing 15. The nuts of the mounting bolts 11 are then tightened. The pressure ring presses against the first through ring 7, and the first annular boss 701 of the first through ring 7 presses against the outer ring of the bearing 5. The second pressure ring 10 presses against the second through ring 8, and the second annular boss 801 of the second through ring 8 presses against the outer ring of the bearing 5. Finally, the arc plate 4 is installed on the inner side of the annular boss bushing 15 to limit the bushing 15 to press against the inner ring of the bearing 5 on the end face of the mounting column 202. Finally, the coupling 1 is installed to connect the connecting column 204 and the power shaft. The installation process of the other end mounting column 202 is similar and will not be described here.

[0070] By setting the arc plate 4 to press the bushing 15, when it is necessary to maintain the equipment on the power shaft side, after the coupling 1 is disassembled, the arc plate 4 can still limit the bushing 15 to prevent the bushing 15 from slipping off, which facilitates maintenance operations.
