Description

Technical Field

[0001] This utility model belongs to the technical field of nut disassembly and assembly tools, specifically relating to a grooved nut disassembly and assembly tool for gearbox bearings. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Mobile machinery vehicles are important special equipment for port loading and unloading operations. They have high workloads and large demand. In order to ensure that the equipment is in good condition and that it operates safely, the gearboxes of the machinery vehicles need to be inspected and maintained regularly.

[0004] The maintenance and repair of transmissions requires a large amount of manpower, which is not only time-consuming but also inefficient. When disassembling transmission bearings, the slotted nuts that lock the bearings must be removed before the bearings can be taken off. Currently, the disassembly and assembly process using pry bars, sledgehammers, and bearing pullers is problematic. Pry bars lack a point of force, making disassembly difficult. The process of using a sledgehammer to strike a copper rod to loosen the nut poses safety hazards due to unpredictable factors such as overly tight nuts, slippery copper rods, and improper operator coordination. Using a three-jaw puller results in a small point of force, which can easily cause injury from ejection, posing safety hazards and low disassembly efficiency. Utility Model Content

[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] The maintenance and repair of transmissions requires a large amount of manpower, which is not only time-consuming but also inefficient. When disassembling transmission bearings, the slotted nuts that lock the bearings must be removed before the bearings can be taken off. Currently, the disassembly and assembly process using pry bars, sledgehammers, and bearing pullers is problematic. Pry bars lack a point of force, making disassembly difficult. The process of using a sledgehammer to strike a copper rod to loosen the nut poses safety hazards due to unpredictable factors such as overly tight nuts, slippery copper rods, and improper operator coordination. Using a three-jaw puller results in a small point of force, which can easily cause injury from ejection, posing safety hazards and low disassembly efficiency.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a tool for disassembling and assembling a grooved nut for a gearbox bearing, such as... Figure 1 As shown, it includes a first fixed plate 1, a second fixed plate 2, a semi-circular block 3, and a connecting rod 4; the connecting rod 4 is provided at one end of the first fixed plate 1, and the second fixed plate 2 is provided at the other end of the first fixed plate 1; a circular groove is provided on the second fixed plate 2, and a number of semi-circular blocks 3 are arranged at intervals on the inner wall surface of the circular groove.

[0026] Several semicircular blocks 3 are positioned within the circular grooves of the second fixed plate 2. The slotted nut is placed within the circular groove of the second fixed plate 2, and the semicircular blocks 3 within the circular groove engage with the grooves on the slotted nut. After engagement, the connecting rod 4 is connected to the torque wrench, and the slotted nut can be disassembled by rotating the torque wrench. During installation, the slotted nut is placed into the circular groove, and then the connecting rod 4 is connected to the torque wrench. The slotted nut can be installed by turning the connecting rod 4 with the torque wrench. This enables rapid disassembly and assembly of the slotted nut, thereby enabling rapid disassembly and assembly of the bearing. The disassembly and assembly are highly efficient and ensure the safety of the disassembly and assembly process.

[0027] The first fixed plate 1 and the second fixed plate 2 are fixedly connected, and the diameter of the first fixed plate 1 is larger than the diameter of the second fixed plate 2. The first fixed plate 1 is fixedly connected to one end of the connecting rod 4, and the other end of the connecting rod 4 is connected to a torque wrench. The connecting rod 4 is a hexagonal prism.

[0028] Torque wrenches work by utilizing the lever principle and the elastic deformation of springs. When the applied torque reaches a preset value, the spring is compressed to a certain extent, triggering the internal pawl mechanism, causing the wrench to make a sound and accompanied by a tactile vibration alarm.

[0029] The hexagonal prism connecting rod 4 is easy to connect to a torque wrench and can also be connected to a pneumatic wrench. By driving the connecting rod 4 to rotate through the pneumatic wrench or torque wrench, the slotted nut in the second fixed plate 2 will rotate clockwise or counterclockwise, thus realizing the disassembly and assembly of the slotted nut.

[0030] The diameter of the circular groove is smaller than the diameter of the second fixing plate 2, and the diameter of the circular groove is smaller than the diameter of the first fixing plate 1. The upper surface of the semicircular block 3 is flush with the upper surface of the second fixing plate 2, and the lower surface of the semicircular block 3 is fixedly connected to the bottom surface of the circular groove. One side of the semicircular block 3 is fixedly connected to the inner wall of the circular groove, and the other side of the semicircular block 3 is engaged with the groove of the slotted nut. Several semicircular blocks 3 are arranged circumferentially with the center of the second fixing plate 2 as the center point.

[0031] The size of the semicircular block 3 is adapted to the groove size of the slotted nut, so that the semicircular block 3 can be engaged with the groove, thereby driving the slotted nut to rotate when the fixed plate rotates.

[0032] Specifically, six semicircular blocks 3 are set, and six semicircular grooves are set on the slotted nut. Each semicircular block 3 is inserted into the corresponding semicircular groove to achieve a snap-fit.

[0033] like Figure 2 As shown, the connecting rod 4 is perpendicular to the first fixed plate 1. The bottom area of ​​one end of the connecting rod 4 is larger than the bottom area of ​​the other end, and the end of the connecting rod 4 with the larger bottom area is connected to the first fixed plate 1.

[0034] Specifically, the connecting rod 4 can be a hexagonal prism with a diameter of 36mm. The end of the connecting rod 4 with a larger bottom area is connected to the first fixed plate 1, which can increase the contact area between the connecting rod 4 and the first fixed plate 1, making the connection more secure.

[0035] How to use a slotted nut removal and installation tool:

[0036] In use, place the slotted nut in the circular groove of the second fixing plate 2, and make the semi-circular block 3 in the circular groove engage with the groove on the slotted nut. After engagement, connect the connecting rod 4 and the torque wrench. Rotate the torque wrench to drive the connecting rod 4 to rotate, thereby causing the first fixing plate 1 and the second fixing plate 2 to rotate. Since the semi-circular block 3 in the second fixing plate 2 is engaged with the slotted nut, the slotted nut can be rotated, thus disassembling the slotted nut. After disassembly, the bearing can be removed from its limiting position. During installation, install the bearing, then place the slotted nut in the circular groove, and then connect the connecting rod 4 to the torque wrench. The connecting rod 4 can be turned with the torque wrench to install the slotted nut, thus limiting the bearing.

[0037] The combination of the first fixing plate 1, the second fixing plate 2, the semi-circular block 3, and the connecting rod 4 achieves labor savings, reducing the original 4-person operation to only 1-2 people; it saves time, reducing operation time by more than 3 hours, and effectively reduces the labor intensity of workers; it replaces the disassembly and assembly process of using copper rods to strike and bolts to pry open holes, avoiding safety hazards caused by unpredictable factors such as overtightening, easy bolt slippage, and excessive elasticity of pry bars, and can accurately and firmly fix it in the slot of the groove nut, improving the safety during operation; it has the positive effects of simple structure, practicality, and reliability.

[0038] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
