Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a special bearing disassembly and assembly tool. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] During crane maintenance, it was found that tapered roller bearings are widely used for rotating shaft pins, resulting in frequent disassembly of these bearings. However, during disassembly, it was often encountered that the bearing mounting hole was not a through hole, but rather had a dust cover at one end (integrated with the bearing housing). The inner hole was slightly larger than the bearing's inner diameter, and the clearance between the inner hole and the outer ring of the bearing was very small (generally 2-3mm), making disassembly still very difficult. The only option was to use a torch to cut it off, but this was challenging, time-consuming, and labor-intensive, and could easily damage the bearing housing, causing unnecessary assembly problems. Therefore, this tooling was designed. It facilitates disassembly, saves time and labor, does not damage the bearing housing, simplifies assembly, and shortens the equipment maintenance cycle. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special bearing disassembly and assembly fixture, including a disassembly mechanism and a bearing assembly. The disassembly mechanism includes a disassembly component, and a connecting component is installed on the disassembly component. An auxiliary component is connected between the bearing assembly and the disassembly component. The auxiliary component includes an auxiliary seat, and the auxiliary seat is a cylindrical structure. Two symmetrically arranged mounting grooves are opened on one outer wall of the auxiliary seat, and mounting frames are snapped into the inner walls of the two mounting grooves. An L-shaped disassembly seat is fixedly connected to one outer wall of each of the two mounting frames.

[0006] By adopting the above structure, the disassembly mechanism facilitates the disassembly and assembly of bearings in the bearing assembly on the ship. The disassembly mechanism consists of a disassembly component, a connecting component, and an auxiliary component. The auxiliary component facilitates the fixing of the bearing, and the connecting component facilitates the connection of the disassembly component to the bearing housing. The disassembly component then pushes the auxiliary component to move, thereby facilitating the quick disassembly of the bearing. The auxiliary component consists of an auxiliary seat and two disassembly seats, which also facilitate the fixing of the bearing.

[0007] In one possible implementation, the auxiliary seat has two symmetrically arranged adjustment components inside, and the adjustment components include a screw rod rotatably mounted on the inner wall of the auxiliary seat. A trapezoidal block is screwed to the outer wall of the screw rod rotatably, and the trapezoidal block is slidably connected to the inner wall of the auxiliary seat.

[0008] By adopting the above structure, the position of the trapezoidal block can be easily adjusted directly by adjusting the setting of the second screw in the component. When the second screw rotates, it directly drives the trapezoidal block to slide in the auxiliary seat.

[0009] In one possible implementation, a groove is formed on one outer wall of the trapezoidal block, and a wedge plate is slidably connected to the inner wall of the groove. One end of the wedge plate is fixedly connected to a limiting seat.

Two circular grooves are formed on one outer wall of the auxiliary seat, and a rotating part is rotatably connected to the inner wall of each of the two circular grooves. One end of the drive shaft of the rotating part is fixedly connected to a screw. The specifications of the trapezoidal block match the specifications of the mounting frame.

[0010] By adopting the above structure, the rotating part directly drives the second screw to rotate. When the second screw rotates, it directly drives the trapezoidal block to move. When the trapezoidal block moves, it directly drives the wedge plate to drive the limit seat to move. When the limit seat extends, it is directly inserted into the mounting frame, thus making it convenient to fix the disassembly seat on the auxiliary seat.

[0011] In one possible implementation, the disassembly assembly includes a disassembly box, and a drive seat is slidably connected to the inner wall of the disassembly box. An installation shaft is fixedly connected to one side of the outer wall of the drive seat, and a contact seat is fixedly connected to one end of the installation shaft.

[0012] By adopting the above structure, the contact seat can be moved directly through the mounting shaft by sliding the drive seat in the disassembly box. When the contact seat moves, it directly pushes the auxiliary seat to disassemble the bearing.

[0013] In one possible implementation, a fixing frame is fixedly connected to the inner wall of the disassembly box, and two screw rods are rotatably connected between the fixing frame and the inner wall of the disassembly box. The drive seat is screwed onto the outer wall of the two screw rods, and a gear is fixedly connected to one end of each of the two screw rods. A servo motor is fixedly connected to the inner wall of the disassembly box, and a gear is fixedly connected to the output shaft of the servo motor. The gear and the two gears mesh with each other. A battery is fixedly connected to one end of the disassembly box.

[0014] By adopting the above structure, the servo motor directly drives the two gears to rotate through the gear 2. When the two gears rotate, they directly drive the screw to rotate. When the two screws rotate, they directly drive the drive seat to move, thus facilitating the drive contact seat to push the auxiliary seat.

[0015] In one possible implementation, the auxiliary component includes a mounting plate fixedly connected to the disassembly box, and two symmetrically arranged mounting ears are fixedly connected to the outer wall of the mounting plate. An L-shaped connecting arm is rotatably connected to the outer wall of each of the two mounting ears on opposite sides. An opening II is opened on one side of the outer wall of each of the two connecting arms, and a clamping component is installed on the inner wall of each of the two opening IIs.

[0016] By adopting the above structure, the mounting plate facilitates the installation of the mounting ears, and the mounting ears facilitate the rotational installation of the connecting arm, which has an L-shaped structure.

[0017] In one possible implementation, the bearing assembly includes a bearing housing, with a limiting ring fixedly connected to the inner wall of the bearing housing, a dust cover fixedly connected to one side of the outer wall of the bearing housing, and a bearing body snapped into the inner wall of the bearing housing, wherein the inner diameter of the bearing body is smaller than the inner diameter of the limiting ring.

[0018] By adopting the above structure, the bearing housing facilitates the installation of the bearing body, the dust cover on the bearing housing provides protection for the bearing body, and the limiting ring assists in the installation of the bearing body.

[0019] In one possible implementation, the clamping assembly includes a clamping box fixedly connected to the inner wall of the second opening, and an opening three is provided on one outer wall of the clamping box, with a clamping block slidably connected to the inner wall of the third opening.

[0020] By adopting the above structure, the sliding installation of the clamping block in the clamping box facilitates the installation of the disassembly components in conjunction with the connecting arm.

[0022] By adopting the above structure, the sliding rod in the clamping box can be used to limit the sliding trajectory of the clamping block, and the spring can be used to drive the clamping block to press against the bearing seat.
