Description

Technical Field

[0001] This utility model relates to the field of roller casting technology, and in particular to a high-precision roller casting. Background Technology

[0002] Roller castings refer to wheel-shaped metal parts manufactured through casting processes. They are commonly used in various mechanical equipment, such as industrial machinery and automated equipment.

[0003] Application number CN202122871989.1 discloses a cast elevator roller, comprising a roller and a rotating device. The roller has a rotating hole, and the rotating device includes a rotary bearing, a first baffle, a second baffle, a connecting screw, and a locking element. The rotary bearing is fixedly connected to the roller, the first baffle is fixedly connected to the roller, the second baffle is fixedly connected to the roller, the connecting screw is rotatably connected to the rotary bearing, and the locking element is fixedly connected to the connecting screw. The rotary bearing allows rotation between the roller and the connecting screw, and the connecting screw allows the cast elevator roller to rotate. Roller castings can be installed on elevators. The first and second baffles shield the rotating bearing inside the rotating hole, preventing dust, particles, and other impurities from affecting the rotating bearing. This improves the stability of the cast elevator rollers during operation. However, the first and second baffles and the rotating bearing are all fixedly connected to the roller. When the rotating bearing inside the roller is damaged, the entire device needs to be replaced. Since the manufacturing of the castings consumes a lot of resources and energy, simply discarding the replaced roller castings would result in a waste of resources and high maintenance costs.

[0007] To better achieve the above objectives, the present invention adopts a further technical solution: a retaining ring is slidably connected inside the rotating port, and the threaded rod is sleeved inside the retaining ring.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: sealing gaskets are fixedly connected to the end faces of the first and second protective plates near the bearing body.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: the bearing body includes a fixed inner ring, a fixed outer ring, rolling elements, and a cage.

[0010] To better achieve the above objectives, the present invention adopts a further technical solution: a cover plate is fixedly connected to one end of the threaded rod, and both the first protective plate and the second protective plate have mounting openings, and the mounting openings on the cover plate and the second protective plate match each other.

[0011] To better achieve the above objectives, the present invention adopts a further technical solution: a baffle is fixedly connected to the inner wall of the rotating opening, and the baffle is annular.

[0012] The beneficial effects of this utility model are: the first and second protective plates can be disassembled by unscrewing the fixing bolts, which makes it convenient for users to replace the bearing body and thus save maintenance costs; the first and second protective plates prevent dust, particles and other impurities from affecting the bearing body, and the sealing gasket can ensure the sealing performance of the bearing body and prevent lubricant leakage.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-3As shown, a high-precision roller casting includes: a roller body 1, with a rubber pad 10 fixedly connected to the side wall of the roller body 1 for anti-slip, shock absorption, and buffering; a rotating opening on the roller body 1, with a baffle 2 fixedly connected to the inner wall of the rotating opening, the baffle 2 being annular to limit the bearing body 3 and prevent the bearing body 3 from slipping off the other end of the rotating opening during installation; the bearing body 3 is slidably connected to the inner wall of the rotating opening, and a threaded rod 4 is installed inside the bearing body 3; the bearing body 3 includes a fixed inner ring, a fixed outer ring, rolling elements, and a cage. The bearing body 3 is existing technology. The inner ring is fixedly connected to the threaded rod 4 and rotates with the threaded rod 4, while the outer ring slides inside the rotating opening and does not rotate. The rolling elements are the core components of the bearing body 3, typically composed of steel balls, rollers, etc. The cage evenly separates the rolling elements to prevent friction and maintain the uniform distribution of the rolling elements. The bearing body 3 is equipped with a fixed protective assembly. The fixed protective assembly includes two sets of bolt fixing ports 5 respectively opened on the two side walls of the roller body 1. The inner wall of the bolt fixing port 5 is provided with internal threads. The fixing bolts 6 are threadedly connected to both sets of bolt fixing ports 5. The first protective plate 7 and the second protective plate 8 are slidably connected to the two sets of fixing bolts 6 respectively. The retaining ring 9 is slidably connected to the rotating port. The threaded rod 4 is sleeved in the retaining ring 9. The main function of the retaining ring 9 is to prevent the bearing body 3 from axially moving in the rotating port. The first protective plate 7 and the second protective plate 8 are both fixedly connected to the end face near the bearing body 3 with sealing washers 11. The sealing washers 11 can ensure the sealing performance of the bearing body 3 and prevent lubricant leakage. The end of the threaded rod 4 is fixedly connected to a cover plate 12. The first protective plate 7 and the second protective plate 8 are both opened with mounting ports. The mounting ports on the cover plate 12 and the second protective plate 8 are matched.

[0019] In this utility model, the user uses the threaded rod 4 to install the casting at the designated installation position. When the bearing body 3 inside the roller body 1 is damaged, the user first removes the casting, then unscrews the fixing bolts 6 at both ends of the roller body 1, and can then remove the first protective plate 7 and the second protective plate 8. The bearing body 3 can then be taken out from the rotating port, making it convenient for the user to replace the bearing body 3 without having to replace the entire casting, thus saving maintenance costs. Furthermore, the first protective plate 7 and the second protective plate 8 can effectively prevent dust, particles and other impurities from affecting the bearing body 3, and the sealing gasket 11 can ensure the sealing performance of the bearing body 3 and prevent lubricant leakage.
