Description

Technical Field

[0001] This utility model belongs to the field of bearing heating, and in particular relates to a multi-station power frequency bearing heating device. Background Technology

[0002] Bearings are widely used mechanical components, mainly fitted onto shafts to reduce friction between the shaft and the bushing. The typical fit between a bearing and a shaft is an interference fit. During assembly, the bearing needs to be heated, utilizing the principle of thermal expansion and contraction to cause the inner ring of the bearing to expand, allowing the bearing to be fitted onto the shaft. Once the bearing cools and shrinks back to its original size, the interference fit between the bearing and the shaft is achieved.

[0003] Current large bearing heating devices have transverse Hertz rods, which require bearings to be mounted on. After prolonged use, the Hertz rods are prone to bending, and the installation and removal of bearings are difficult each time the heating device is installed. Therefore, a multi-station power frequency bearing heating device is needed to solve the problems of the transverse Hertz rod structure of large bearing heating devices being difficult to use and the difficulty of installing and removing bearings. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station industrial frequency bearing heating device, which aims to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, a multi-station industrial frequency bearing heating device is provided, comprising a fixed tube frame, a movable tube frame, a support plate, casters, an iron core, and a coil. A fixed plate is bolted to the top of the fixed tube frame, and multiple rows of slide rails are bolted to the top of the fixed plate. Multiple rows of pulleys are installed within the slide rails, and the pulleys are bolted to the bottom of the movable tube frame. A toothed rack is fixedly connected to the bottom of the movable tube frame. A motor base is bolted to the top of the fixed plate, and a motor is bolted to the top of the motor base. A drive gear is coaxially fixedly connected to the motor's output end. When the drive gear rotates, it drives the movable tube frame to slide laterally along the slide rails. A bearing plate is provided on the top of the movable tube frame, and a pad is fixedly connected to the top of the bearing plate. An clearance groove is provided on the top of the bearing plate.

[0006] The bottom tube frame of the device is made of multiple sets of tubes spliced ​​together. An iron core is bolted to one side of the top of the fixed plate. The iron core is tubular and C-shaped with the opening facing the left and right sides. Multiple sets of coils are set on the iron core. Hertz rods are fixedly connected to the opening of the iron core, which ensures that the workstation has mobility, increases the lateral load-bearing structure of the bearing, and solves the problem of bearing deformation under the load of Hertz rods for a long time.

[0007] Preferably, the Hertzite rod is fixed by an electromagnet, and a positioning plate is provided at the bottom of the Hertzite rod on the fixing plate. The positioning plate is provided with a positioning groove, thereby ensuring accurate positioning of the Hertzite rod.

[0008] Preferably, a handle is provided on one side of the Hertzite rod, and a sliding roller is provided at the top of the opening of the iron core, thereby ensuring that the Hertzite rod is easy to pull up and preventing it from tipping over when installed and used.

[0009] Preferably, a support rod is bolted to the side of the fixing plate away from the Hertzite rod. A mounting base is movably connected to the top of the support rod. A motor is bolted to the top of the mounting base. An active gear is provided at the output end of the motor. A winch is movably connected to the top of the mounting base. A passive gear is fixedly connected to one side of the winch. The active and passive gears mesh with each other. A steel cable is fixedly connected to the winch. A sliding roller is provided on the side of the mounting base near the Hertzite rod. The steel cable is attached to the top of the sliding roller and hangs down. A hook is provided on the hanging end.

[0010] When using this utility model, it can be installed as needed according to the preset. Multiple bearings can be placed on the top of the support plate, ensuring that the inner hole of the bearing is aligned with the clearance groove. The electromagnet adsorption of the device is canceled, and the bearing is lifted by hooking the ferrite rod hoisting position, so that the bearing is moved under the ferrite rod. The ferrite rod is then lowered by hook for installation, and the ferrite rod is fixed by electromagnet. This allows the heating device to heat the bearing. After heating is completed, the above steps are repeated to remove the bearing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The device is effective for heating large bearings. By changing the direction of the heating device and the way the Hertzite rod is installed, the problems of the Hertzite rod structure being difficult to use and the bearing installation and disassembly being difficult are solved. At the same time, by adding a structure, the Hertzite rod will not directly bear the weight of the bearing. The multi-station design makes heating and subsequent work more convenient and allows for direct installation to the next step. Attached Figure Description

[0020] Example 1

[0021] Please see Figure 1-3 As shown, the structure and structural effects of device embodiment 1 are as follows:

[0022] The top of the fixed pipe rack 1 is bolted to a fixed plate 11, the top of the fixed plate 11 is bolted to a multi-row slide rail 12, the slide rail 12 is provided with a multi-row pulley 25, the pulley 25 is bolted to the bottom of the movable pipe rack 2, the bottom of the movable pipe rack 2 is fixedly connected to a toothed rack 24, the top of the fixed plate 11 is bolted to a motor base 4, the top of the motor base 4 is bolted to a motor 52, and the output end of the motor 52 is coaxially fixedly connected to a drive gear 41, the top of the movable pipe rack 2 is provided with a bearing plate 21, the top of the bearing plate 21 is fixedly connected to a pad 22, and the top of the bearing plate 21 is provided with a clearance groove 23.

[0023] Furthermore, the bottom tube frame of the device is made of multiple sets of tubes spliced ​​together. The top side of the fixing plate 11 is bolted to an iron core 32. The iron core 32 is tubular and C-shaped with the opening facing the left and right sides. Multiple sets of coils 33 are set on the iron core 32. Hertz rods 3 are fixedly connected to the opening of the iron core 32.

[0024] The structure of Embodiment 1 described above can ensure that the motor 52 can drive the tooth structure to move through the active gear 41 structure, thereby pulling the moving tube frame 2 to move the bearing plate 21, thus realizing the reciprocating action of multiple stations. At the same time, it avoids the Hertzspar rod 3 being directly subjected to force, so that the bearing is placed on the top of the bearing plate 21 and supported by the pad block 22. However, the structure of Embodiment 1 still has the defects of difficult disassembly of the Hertzspar rod 3 and the Hertzspar rod 3 being too heavy and prone to danger.

[0025] Example 2

[0026] Please see Figure 4 As shown, the device embodiment 2 modifies the structure and its effects based on the original embodiment 1 as follows:

[0027] The Hertzite rod 3 is fixed by electromagnet. The fixing plate 11 is located at the bottom of the Hertzite rod 3 and has a positioning plate with a positioning groove. The Hertzite rod 3 has a handle 31 on one side and a sliding roller 34 at the top of the opening of the iron core 32.

[0028] Furthermore, a support rod 5 is bolted to the side of the fixed plate 11 away from the Hertzian rod 3. A mounting base 51 is movably connected to the top of the support rod 5. A winch 54 is movably connected to the top of the mounting base 51. A steel cable 56 is fixedly connected to the winch 54. A sliding roller 34 is provided on the side of the mounting base 51 near the Hertzian rod 3. The steel cable 56 is attached to the top of the sliding roller 34 and hangs down. A hook 57 is provided on the hanging end.

[0029] Furthermore, a motor 52 is bolted to the top of the mounting base 51, and an active gear 53 is provided at the output end of the motor 52. A passive gear 55 is fixedly connected to one side of the winch 54, and the active gear 53 and the passive gear 55 mesh with each other.

[0030] The structure of Embodiment 2 described above ensures that the installation, positioning and disassembly of the Hertzite rod 3 are faster and simpler. The use of the hook 57 structure solves the problem of the difficulty and danger of lifting the Hertzite rod 3. At the same time, multiple sets of sliding rollers 34 provide anti-sway guidance for the steel cable 56 and the lifted Hertzite rod 3. Due to the height of the bearing plate 21, it is not necessary to lift the Hertzite rod 3 too high. Therefore, the Hertzite rod 3 can be made to fit one side of the sliding roller 34 to achieve the anti-sway effect.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
