Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and particularly to a special bearing disassembly and assembly tooling. Background Art

[0002] Bearings are important components in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0003] During the maintenance of cranes, it is found that tapered roller bearings are widely used for rotating shaft pins, so the disassembly of such bearings is also relatively frequent. However, during the disassembly process, it is often encountered that the bearing installation hole is not a through hole, but one end has a dust cover (integrated with the bearing housing), the inner hole is slightly larger than the inner diameter of the bearing, and the gap with the outer ring of the bearing is very small (generally 2 - 3 mm). Disassembly is still very difficult and can only be removed by using a fire knife. However, cutting has certain difficulties, is time-consuming and laborious, and is likely to cut the bearing housing, bringing unnecessary trouble to the assembly. Therefore, this tooling is designed, which is convenient for disassembly, time-saving and labor-saving, has no damage to the bearing housing, brings convenience to the assembly, and shortens the equipment maintenance period. Summary of the Invention

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

[0005] To achieve the above purpose, the present invention provides the following technical solution: A special bearing disassembly and assembly tooling, including a disassembly mechanism and a bearing assembly. The disassembly mechanism includes a disassembly component, and a connection 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 of a cylindrical structure. Two symmetrically arranged installation grooves are opened on the outer wall of one side of the auxiliary seat, and installation frames are clamped on the inner walls of the two installation grooves. L-shaped disassembly seats are fixedly connected to the outer walls of one sides of the two installation frames.

[0006] By adopting the above structure, the disassembly and assembly of the bearings in the bearing assembly on the ship are facilitated through the setting of the disassembly mechanism. The disassembly mechanism is composed of a disassembly component, a connection component and an auxiliary component. The setting of the auxiliary component facilitates the fixation of the bearing. The setting of the connection component facilitates the connection of the disassembly component to the bearing housing. Then, by pushing the auxiliary component to move through the disassembly component, the bearing can be quickly disassembled. The auxiliary component is composed of an auxiliary seat and two disassembly seats, and at the same time, it is convenient to fix the bearing.

[0007] In a possible implementation manner, two symmetrically arranged adjusting components are arranged inside the auxiliary seat. The adjusting component includes a screw rod two rotatably installed on the inner wall of the auxiliary seat. A trapezoidal block is screwed on the outer wall of the screw rod two, 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 conveniently and directly adjusted by adjusting the setting of the second screw in the adjusting component. When the second screw rotates, it directly drives the trapezoidal block to slide in the auxiliary seat.

[0036] Embodiment Two Based on Embodiment 1, this embodiment introduces the specific structure of the pressing component 9 in a special bearing disassembly and assembly tooling. Figure 9 As shown, the same screw three 39 is rotatably connected to the inner walls on both sides of the pressing box 35. The pressing block 38 is screwed on the outer wall of the screw three 39.

A rotating disk 40 is rotatably connected to the outer wall of one side of the pressing box 35, and one end of the transmission shaft of the rotating disk 40 is fixedly connected to the worm. By directly driving the worm through the rotating disk 40 to drive the worm gear 41 to rotate, when the worm gear 41 rotates, it directly drives the screw three 39 to rotate, and when the screw three 39 rotates, it directly drives the pressing block 38 to press on the bearing seat 31.

[0037] Working principle: When in use, when it is necessary to disassemble the bearing body 32 in the bearing seat 31, first place the disassembly seat 22 from one end of the dust cover 34 to disengage from the bearing body 32. The two L-shaped disassembly seats 22 directly contact the bearing body 32. Then, insert the auxiliary seat 20 into the bearing body 32 from the other end of the bearing seat 31. When the mounting frames 23 on the two disassembly seats 22 are inserted into the mounting grooves 21, rotate the rotating part 26 to directly drive the second screw 28 to rotate. The rotation of the second screw 28 directly drives the trapezoidal block 29 to move. When the trapezoidal block 29 moves away from the rotating part 26, it directly pushes the limit seat 25 into the mounting frame 23, thereby facilitating the fixation of the disassembly seat 22 on the auxiliary seat 20. At this time, install the disassembly component 3 on the bearing seat 31 through the connection component 4. During installation, after the disassembly component 3 is installed, directly start the servo motor 15. When the servo motor 15 starts, it directly drives the two first gears 13 to rotate through the second gear 14. When the two first gears 13 rotate, they directly drive the two first screws 11 to rotate synchronously. When the first screws 11 rotate, they directly drive the drive seat 17 to move. When the drive seat 17 moves, it directly drives the contact seat 19 to move through the mounting shaft 18. When the contact seat 19 pushes the auxiliary seat 20 away from the disassembly component 3, it is convenient to disassemble the bearing body 32 from the bearing seat 31. During the installation of the connection component 4, first snap the connecting arm 8 onto the bearing seat 31. The pressing block 38 in the pressing component 9 is pressed against the bearing seat 31 under the drive of the spring 37, or drive the worm to drive the worm gear 41 to rotate by rotating the rotating disc 40. When the worm gear 41 rotates, it directly drives the third screw 39 to rotate. When the third screw 39 rotates, it directly drives the pressing block 38 to move. When the pressing block 38 is pressed against the bearing seat 31, it is convenient to fix the disassembly component 3 on the bearing seat 31.
