Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a split-type roller bearing housing steel casting. Background Technology

[0002] Split roller bearing housings are a type of bearing housing design that uses an upper and lower split structure. A typical structure includes an upper half ring and a lower half ring, which are connected by screws or fixing devices to form a complete bearing support. This design allows only the upper bearing housing to be removed during maintenance, exposing the bearing for easy inspection or replacement. Its working principle is similar to that of an integral bearing housing, supporting the rotating bearing to bear axial and radial loads, while protecting the internal lubrication of the bearing through a sealing structure.

[0003] Split roller bearing housings have a wide range of applications. When used in high-temperature and high-humidity environments, the lubricating oil at both ends of the bearing housing is prone to absorbing water and emulsifying, which reduces the lubricating effect of the oil and makes the bearing more prone to failure during operation, requiring maintenance. In the existing technology, split roller bearing housings use a large number of screws. In high-temperature and high-humidity environments, screws are prone to oxidation, which can cause the screws to jam with the bearing housing, making the maintenance progress of the bearing housing slow and affecting the work efficiency of the workers. Utility Model Content

[0023] According to the mounting base 1, when it is necessary to install and fix the split roller bearing seat, first place the mounting base 1, then rotate the screw 25 clockwise. The screw 25 moves clockwise towards the threaded hole 24 to fix the mounting base 1. Then fix the lower half ring 3 to the mounting base 1. Then connect the bearing body 4 to the lower half ring 3. Then move the upper half ring 2 towards the lower half ring 3 so that the groove 27 slides along the U-shaped block 26, so that the upper half ring 2 and the lower half ring 3 complete the initial snap-fit, achieving the effect of quick positioning and support of the split roller bearing seat, so that the staff can carry out the next step of work.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Two rotating blocks 13 are disposed inside a rectangular groove 11. Two connecting rods 14 are disposed inside the rectangular groove 11. A slider 28 is fixedly connected to the outer circular wall of the rotating block 13 near the rack 7. The sliding groove 10 is movably sleeved with the slider 28. A limit rod 12 is movably sleeved on the inner circular wall of the rotating block 13. A first connecting plate 15 is movably sleeved on the outer circular wall of the limit rod 12 on the left side. The bottom of the first connecting plate 15 is movably sleeved with the connecting rod 14 on the left side. A second connecting plate 16 is movably sleeved on the outer circular wall of the connecting rod 14. The second connecting plate 16 is located away from the first connecting rod 14. One end of a connecting plate 15 is movably sleeved with a connecting rod 14 located on the right side. A third connecting plate 17 is movably sleeved on the outer circular wall of the connecting rod 14 located on the right side. A positioning rod 19 is fixedly connected to the side of the third connecting plate 17 away from the rack 7. The third connecting plate 17 is movably sleeved with a limiting rod 12 located on the right side. A rotating rod 8 is provided inside the rectangular groove 11.

The support groove 21 is movably sleeved with the positioning rod 19.

[0025] After the mounting base 1 and the lower half-ring 3 are placed using the rack 7, the upper half-ring 2 is first moved closer to the lower half-ring 3, causing the rack 7 to move closer to the lower half-ring 3. This causes the slider 28 to slide inside the groove 10, causing the gear 9 meshing with the rack 7 to begin rotating counterclockwise. Subsequently, the rotating rod 8 and the turntable 20 begin rotating counterclockwise, causing the positioning rod 19 to begin rotating clockwise. Then, the third connecting plate 17 begins rotating clockwise around the positioning rod 19, and the second connecting plate 16 and the rotating block 13 move away from the positioning rod 19, thus... The connecting plate 15 begins to move closer to the rotating block 13, then the limiting rod 12 begins to rotate clockwise, and the slider 28 moves away from the slide groove 10. When the rack 7 moves to the bottom of the rectangular groove 11, the gear 9 stops rotating. Then the turntable 20, rotating rod 8, positioning rod 19, connecting rod 14, first connecting plate 15, second connecting plate 16, third connecting plate 17, connecting rod 14, mounting base 1, and limiting rod 12 stop rotating. The limiting rod 12 rotates counterclockwise under the gravity of the slider 28, and then the slider 28 fits against the inside of the slide groove 10, at the upper half... Ring 2 and lower half ring 3 are fully engaged, completing the installation of upper half ring 2 and lower half ring 3, improving the stability of the split roller bearing housing. When the split roller bearing housing needs maintenance, first move upper half ring 2 away from lower half ring 3, then move rack 7 away from lower half ring 3, and then slide slider 28 inside slide groove 10, causing gear 9 meshing with rack 7 to start rotating clockwise. Then, rotating rod 8 and turntable 20 start rotating clockwise, and then positioning rod 19 starts rotating counterclockwise. Then, third connecting plate 17 starts rotating counterclockwise around positioning rod 19. The first connecting plate 15 moves away from the rotating block 13, and the limiting rod 12 rotates counterclockwise. The slider 28 moves away from the slide groove 10. When the slide groove 10 disengages from the slider 28, the upper half ring 2 and the lower half ring 3 also disengage. This allows the upper half ring 2 and the lower half ring 3 to be quickly disengaged when the split roller bearing seat needs to be repaired, making it convenient for workers to repair the split roller bearing seat and improving their work efficiency.

[0026] Working principle: Please refer to Figures 1-4As shown, according to the installed base 1, when it is necessary to install and fix the split roller bearing seat, first place the installed base 1, then rotate the screw 25 clockwise. The screw 25 moves clockwise towards the threaded hole 24 to fix the installed base 1. Then fix the lower half ring 3 to the installed base 1. Then connect the bearing body 4 to the lower half ring 3. Then move the upper half ring 2 towards the lower half ring 3 so that the groove 27 slides along the U-shaped block 26, so that the upper half ring 2 and the lower half ring 3 complete the initial snap-fit, achieving the effect of quick positioning and support of the split roller bearing seat, so that the staff can carry out the next step of work.

[0027] After the mounting base 1 and the lower half-ring 3 are placed using the rack 7, the upper half-ring 2 is first moved closer to the lower half-ring 3, causing the rack 7 to move closer to the lower half-ring 3. This causes the slider 28 to slide inside the groove 10, causing the gear 9 meshing with the rack 7 to begin rotating counterclockwise. Subsequently, the rotating rod 8 and the turntable 20 begin rotating counterclockwise, causing the positioning rod 19 to begin rotating clockwise. Then, the third connecting plate 17 begins rotating clockwise around the positioning rod 19, causing the second connecting plate 16 and the rotating block 13 to move away from the positioning rod 19. A connecting plate 15 begins to move closer to the rotating block 13, then the limiting rod 12 begins to rotate clockwise, causing the slider 28 to move away from the slide groove 10. When the rack 7 moves to the bottom of the rectangular groove 11, the gear 9 stops rotating. Then, the turntable 20, rotating rod 8, positioning rod 19, connecting rod 14, first connecting plate 15, second connecting plate 16, third connecting plate 17, connecting rod 14, mounting base 1, and limiting rod 12 stop rotating. The limiting rod 12 rotates counterclockwise under the gravity of the slider 28, and then the slider 28 fits against the inside of the slide groove 10. Half-ring 2 and lower half-ring 3 are fully engaged, completing the installation of upper half-ring 2 and lower half-ring 3, improving the stability of the split roller bearing housing. When the split roller bearing housing needs maintenance, firstly, the upper half-ring 2 is moved away from the lower half-ring 3, then the rack 7 is moved away from the lower half-ring 3, and then the slider 28 slides inside the groove 10, causing the gear 9 meshing with the rack 7 to start rotating clockwise. Then, the rotating rod 8 and the turntable 20 start rotating clockwise, and then the positioning rod 19 starts rotating counterclockwise. Subsequently, the third connecting plate 17 rotates counterclockwise around the positioning rod 19. The first connecting plate 15 moves away from the rotating block 13, and the limiting rod 12 rotates counterclockwise. The slider 28 moves away from the slide groove 10. When the slide groove 10 disengages from the slider 28, the upper half ring 2 and the lower half ring 3 also disengage. This allows the upper half ring 2 and the lower half ring 3 to be quickly disengaged when the split roller bearing seat needs to be repaired, making it convenient for workers to repair the split roller bearing seat and improving their work efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
