Technical Field

[0001] This utility model relates to the technical field, and in particular to a tool for disassembling planetary gears of a scissor car reducer. Background Technology

[0002] In the maintenance and repair of scissor lift gears, the disassembly of planetary gears is a crucial yet challenging task. The planetary gears are tightly fitted to the gearbox body. Traditional disassembly methods primarily involve using tools such as hammers to strike, pull, or lift the planetary gears from the gearbox body. However, these methods have significant drawbacks: First, they are inefficient and can easily cause potential damage to the planetary gears during disassembly, affecting their subsequent performance and lifespan. Furthermore, the market currently lacks specialized disassembly tools designed specifically for scissor lift gear planetary gears, making the process lack professionalism and systematic approach. Engineers and maintenance personnel often rely on manual operation, resulting in a time-consuming and labor-intensive process, increasing the complexity and cost of maintenance.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0021] like Figure 1 The diagram illustrates a preferred embodiment of a tool for disassembling planetary gears in a scissor lift gear, comprising:

[0022] Disk 1;

[0023] The first bolt 2 is located at the center of the disk 1;

[0024] The second bolt 3 is located on the outer edge of the disk 1 and is connected to the connecting hole on the planetary gear.

[0025] The pad 4 has a circular cross-section and is positioned opposite the disc 1. One end of the first bolt 2 abuts against the pad 4.

[0026] Furthermore, as a preferred embodiment, both the disc 1 and the pad 4 are made of iron.

[0027] Furthermore, as a preferred embodiment, the diameter of the disk 1 is preferably set to 16.5 cm, and the thickness of the disk 1 is preferably set to 2 cm.

[0028] Furthermore, as a preferred embodiment, the diameter of the pad 4 is preferably set to 10cm, and the thickness of the pad 4 is preferably set to 2cm.

[0029] Furthermore, as a preferred embodiment, the first bolt 2 is preferably configured as an M20 bolt.

[0030] Furthermore, as a preferred embodiment, the second bolt 3 is preferably configured as an M6 bolt.

[0031] Furthermore, as a preferred embodiment, the center of the disk 1 is provided with a first threaded hole, and the first bolt 2 is disposed in the first threaded hole.

[0032] Furthermore, in a preferred embodiment, one end of the first bolt 2 passes through the first threaded hole, and the other end of the first bolt 2 is connected to an external pneumatic wrench. Furthermore, the pneumatic wrench can drive the first bolt 2 to rotate, thereby causing the disc 1 to move upwards along the first bolt 2.

[0033] Furthermore, as a preferred embodiment, three second threaded holes are evenly provided on the outer edge of the disk 1. The three second threaded holes are distributed along the circumference of the disk 1, and a second bolt 3 is provided in each second threaded hole.

[0034] Furthermore, as a preferred embodiment, the diameter of the first threaded hole is larger than the diameter of the second threaded hole.

[0035] Furthermore, in a preferred embodiment, the planetary gear has at least three connecting holes, which are directly opposite the second threaded holes. One end of the second bolt 3 extends into the connecting hole, and the planetary gear is connected to the disk 1 via the second bolt 3. The connecting hole is a threaded hole, and it is threadedly engaged with the second bolt 3.

[0036] Furthermore, as a preferred embodiment, a circular groove 41 is provided in the center of the pad 4, and one end of the first bolt 2 abuts against the circular groove 41.

[0037] Furthermore, as a preferred embodiment, it also includes: a nut 5, which is sleeved around the second bolt 3.

Furthermore, providing two nuts 5 helps to prevent the second bolt 3 from loosening due to vibration or load changes during the disassembly of the planetary gear.

[0040] Furthermore, as a preferred embodiment, when it is necessary to detach the planetary gear from the reducer body, firstly, the pad 4 can be placed inside the reducer body, then the disc 1 can be placed on the upper end of the planetary gear, aligning the second threaded hole on the disc 1 with the connecting hole on the planetary gear, aligning the first threaded hole on the disc 1 with the circular groove 41 on the pad 4, then inserting the first bolt 2 into the first threaded hole and the circular groove 41, inserting the second bolt 3 into the second threaded hole and the connecting hole, and locking the planetary gear and the disc 1 by tightening the nut 5. Using an air wrench, the first bolt 2 is rotated, thereby driving the disc 1 to move upward along the first bolt 2. Under the action of the second bolt 3, the planetary gear can move upward with the disc 1, thus enabling the planetary gear to detach from the reducer body.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
