Description

Technical Field

[0001] This utility model relates to a bearing press-in tool for gearbox repair, and more particularly to a bearing press-in tool for gearbox repair applied in the field of gearbox bearings. Background Technology

[0002] Transmission bearings are critical mechanical components installed in automotive transmissions, primarily used to support the drive shaft and gear system, and to coordinate power transmission and speed regulation. Their core functions are as follows:

[0003] Supporting transmission components (replacing direct friction between shaft and hole with rolling contact to reduce transmission resistance and ensure precise rotation of shafts and gears), reducing friction and energy consumption (using ball or roller structures to significantly reduce sliding resistance during rotation, reduce power loss, and improve power transmission efficiency), regulating power and speed (supporting the transmission gear set, allowing different gears and shafts to rotate at different speeds, thereby adjusting engine output torque and vehicle speed to adapt to changes in road conditions), and providing overload protection (through friction transmission structure design, automatic slippage under abnormal loads prevents mechanical components from being damaged due to overload). The application characteristics of transmission bearings are: wear resistance and stability (needing to withstand high speeds, high loads, and frequent shifting impacts, therefore requiring high material hardness, rust resistance, and assembly precision) and wide applicability (not only used in automotive transmissions, but also in differential gears, electric motors, industrial machinery, and other fields). Through the above functions, transmission bearings have become a core component ensuring the efficient and reliable operation of automotive power systems.

[0004] When installing transmission bearings, personnel use transmission maintenance bearing press-in tools to press them into the transmission. However, most of these tools lack a press-in positioning mechanism, making it difficult to ensure that the bearing remains perpendicular to the shaft hole during the press-in process. This causes some inconvenience for personnel when pressing in and installing the bearing. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when existing gearbox repair bearing press-in tools press in and install gearbox bearings, most of them do not have a press-in positioning mechanism, so it is difficult to ensure that the bearing and the shaft hole remain perpendicular during the press-in process.

[0006] To solve the above problems, this utility model provides a bearing pressing tool for gearbox repair, including a pressing body, a sleeve ring fixedly sleeved on the outer end of the pressing body, a connecting pipe threaded to the outer end of the sleeve ring, a bent tube movably inserted at the end of the connecting pipe away from the sleeve ring, a limit tube threaded to the side end of the connecting pipe, a plurality of limit grooves movably inserted with the limit tube at the outer end of the bent tube, a rotating tube threaded to the side end of the bent tube, a round block fixedly connected to the end of the rotating tube away from the bent tube, and a suction cup fixedly connected to the end of the round block away from the rotating tube.

[0007] In the aforementioned bearing press-in tool for gearbox repair, the direction of pressing in and installing the bearing can be positioned and limited, thereby ensuring that the bearing and the shaft hole remain perpendicular and avoiding damage to the bearing or gearbox housing due to tilting.

[0008] As a further improvement of this application, an auxiliary ring is fixedly connected to the outer end of the limiting tube, and a pair of auxiliary tubes are fixedly connected to the outer end of the auxiliary ring.

[0009] As a further improvement to this application, the upper end of the limiting tube extends out from the connecting tube, and the outer end of the auxiliary tube is engraved with anti-slip texture.

[0010] As a further improvement of this application, a pair of sliding grooves are provided on the inner wall of the connecting pipe, and a pair of sliders that are slidably connected to the outer end of the bent pipe are fixedly connected.

[0011] As a further improvement of this application, a reinforcing groove is provided inside the bent pipe, and a reinforcing ring is rotatably connected inside the reinforcing groove. The inner wall of the reinforcing ring is fixedly connected to the outer end of the rotating pipe.

[0012] As a further improvement of this application, the side end of the bend is provided with a threaded hole that is connected to the rotating pipe thread. The threaded hole communicates with the reinforcing groove, and the diameter of the threaded hole is smaller than the diameter of the reinforcing groove.

[0013] As another improvement of this application, a plug-in groove is provided at one end of the round block near the rotating tube. An air vent communicating with the suction cup is provided on the inner wall of the plug-in groove. A sealing seat is movably inserted inside the plug-in groove. The sealing seat is magnetically connected to the inner wall of the plug-in groove through a magnetic coating.

[0014] 1. In use, the movable bend tube can be adjusted to change the length of its side end extending from the connecting tube, thereby adjusting the distance between the two opposing suction cups. Then, the limiting tube is installed on the connecting tube, with its lower end entering the limiting groove to fix the bend tube. After that, the rotating tube is rotated to adjust the length of its side end extending from the bend tube. When the rotating tube moves, it will drive the suction cups to rotate together. After adjusting the position of the suction cups, during the pressing of the bearing, the suction cups are made to adhere to the mounting platform or plane. The connecting tube, bend tube, rotating tube, and suction cups are used to position and limit the presser body to prevent the presser body from moving in other directions during installation. In use, this application can position and limit the direction of pressing the bearing, thereby ensuring that the bearing and shaft hole remain perpendicular and avoiding damage to the bearing or gearbox housing due to tilting.

[0015] 2. After use, when removing the tool from the platform or flat surface, pull the sealing seat to remove it from the insertion slot, thereby breaking the vacuum of the suction cup and losing its adsorption effect on the platform or flat surface, making it easier for personnel to remove the suction cup from the platform or flat surface. Finally, remove the tool from the platform or flat surface. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1-4 A bearing press-in tool for gearbox repair is shown, including a press-in body 1. A sleeve ring 2 is fixedly sleeved on the outer end of the press-in body 1. A connecting pipe 3 is threaded to the outer end of the sleeve ring 2. A bent pipe 4 is movably inserted at the end of the connecting pipe 3 away from the sleeve ring 2. A limiting pipe 6 is threaded to the side end of the connecting pipe 3. A plurality of limiting grooves 7 are opened at the outer end of the bent pipe 4 and are movably inserted into the limiting pipe 6. A rotating pipe 8 is threaded to the side end of the bent pipe 4. A round block 9 is fixedly connected to the end of the rotating pipe 8 away from the bent pipe 4. A suction cup 10 is fixedly connected to the end of the round block 9 away from the rotating pipe 8.

[0026] An auxiliary ring is fixedly connected to the outer end of the limiting tube 6, and a pair of auxiliary tubes are fixedly connected to the outer end of the auxiliary ring. The auxiliary tubes facilitate the rotation of the limiting tube 6 by personnel. The upper end of the limiting tube 6 extends out of the connecting tube 3. The outer end of the auxiliary tube is engraved with anti-slip texture. A pair of sliding grooves 11 are opened on the inner wall of the connecting tube 3. A pair of sliders 12 that are slidably connected to the outer end of the bent tube 4 are fixedly connected to the sliding grooves 11. The sliders 12 can prevent the bent tube 4 from rotating inside the connecting tube 3.

[0027] The inside of the bend 4 is provided with a reinforcing groove, and a reinforcing ring 13 is rotatably connected inside the reinforcing groove. The reinforcing ring 13 can prevent the rotating pipe 8 from separating from the bend 4. The inner wall of the reinforcing ring 13 is fixedly connected to the outer end of the rotating pipe 8. The side end of the bend 4 is provided with a threaded hole that is threadedly connected to the rotating pipe 8. The threaded hole communicates with the reinforcing groove, and the diameter of the threaded hole is smaller than the diameter of the reinforcing groove.

[0028] The application is used in the following steps:

[0029] Step 1: When in use, the movable bend 4 can be adjusted to adjust the length of its side end extending from the connecting tube 3, thereby adjusting the distance between the opposite pair of suction cups 10. Then, the limiting tube 6 is installed on the connecting tube 3 so that its lower end enters the limiting groove 7 to fix the bend 4.

[0030] Then rotate the rotating tube 8 and adjust the length of its side end extending from the bend 4. When the rotating tube 8 moves, it will drive the suction cup 10 to rotate together.

[0031] Step 2: After adjusting the position of the suction cup 10, during the pressing of the bearing, make the suction cup 10 adhere to the installation platform or plane. Use the connecting pipe 3, the bent pipe 4, the rotating pipe 8 and the suction cup 10 to position and limit the presser body 1 to prevent the presser body 1 from moving in other directions during installation.

[0032] In summary, when in use, this application can position and limit the direction of the press-fit bearing, thereby ensuring that the bearing and the shaft hole remain perpendicular and avoiding damage to the bearing or gearbox housing due to tilting.

[0033] Second implementation method:

[0034] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0035] Figure 5 The circular block 9 has an insertion groove 14 at one end near the rotating tube 8. An air vent 15 communicating with the suction cup 10 is provided on the inner wall of the insertion groove 14. A sealing seat 16 is movably inserted inside the insertion groove 14. The sealing seat 16 is magnetically connected to the inner wall of the insertion groove 14 through the magnetic coating 5.

[0036] After use, when removing the tool from the platform or plane, the sealing seat 16 can be pulled to remove it from the insertion slot 14, thereby breaking the vacuum of the suction cup 10 and losing its adsorption effect on the platform or plane, making it easier for personnel to remove the suction cup 10 from the platform or plane. Finally, the tool can be removed from the platform or plane.

[0037] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
