Abstract
Description
Technical Field
[0001] This utility model relates to the field of tracked vehicle maintenance technology, and more specifically, to a tool for disassembling and assembling the balance shaft support sleeve of a tracked vehicle. Background Technology
[0002] Tracked vehicles (such as tracked armored vehicles, engineering machinery, and special vehicles) are widely used in complex terrains and high-intensity working conditions, possessing excellent off-road capabilities and load-bearing capacity. In the running gear system of these vehicles, the balance shaft support sleeve plays a crucial role in support and cushioning, and is one of the important components ensuring the stable operation of the tracked system.
[0003] However, due to the tight fit between the support sleeve and the balance shaft, and the enclosed structure of their location, traditional disassembly and assembly methods generally suffer from low efficiency, high labor intensity, limited operating space, and potential safety hazards. Especially after long-term use or high-load operation, the support sleeve and mating parts are prone to corrosion, jamming, or deformation, further increasing the difficulty of disassembly and assembly.
[0004] Currently, some disassembly and assembly tools on the market still use manual pry bars and simple sockets, which not only rely heavily on the operator's skills but also pose risks such as flying parts and tool slippage during operation, resulting in significant safety hazards and potential equipment damage. Furthermore, traditional tools lack effective collection and control of contaminants such as oil and debris during use, hindering on-site environmental management and increasing subsequent cleaning and maintenance workload.
[0005] Therefore, there is an urgent need for a new type of balance shaft support sleeve disassembly tool to improve disassembly efficiency, ensure operational safety, reduce manual intervention, simplify tool maintenance and cleaning, and extend tool life. Utility Model Content
[0006] 1. Technical problems to be solved
[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tool for disassembling and assembling the balance shaft support sleeve of a tracked vehicle. It utilizes the cooperation of an electric wrench and a wrench to quickly and stably drive the support sleeve to rotate at high speed, thereby realizing the rapid disassembly of the balance shaft, simplifying tool maintenance and cleaning, and extending the tool's service life.
[0008] 2. Technical Solution
[0009] To solve the above problems, the present invention adopts the following technical solution.

A cylinder is mounted inside the splash guard. The balance shaft is coaxially fitted with the cylinder and is located at the bottom of the cylinder. A bearing is provided at the top of the cylinder. A perforated plate is provided between the bearing and an electric wrench. An electric wrench is mounted on the bearing. A weight reduction hole is provided on the front side of the cylinder.
[0011] Based on the above features, the top of the splash-proof cylinder has an opening, and the bottom of the splash-proof cylinder has a cleaning plate.
[0012] In some embodiments, the upper side of the cleaning plate is a cylinder, and the top of the cylinder is provided with a plum blossom groove, which is located on the plum blossom plate.
[0013] Based on the above features, the bottom of the cylinder is provided with a pin, and the inner side of the bottom of the cylinder is provided with a stepped space.
[0014] In some embodiments, the bearing is provided with a retaining ring on its inner side, and the cylinder is provided with a special disassembly device for rotation, and the special disassembly device for rotation is provided with a return spring inside.
[0015] Based on the above characteristics, the inner wall of the anti-splash barrel is equipped with an energy-absorbing sponge layer, which is used to absorb the impact energy when the steel ball splashes and prevent the steel ball from rebounding and causing damage.
[0016] In some embodiments, the length of the splash guard is less than or equal to the length of the cylinder, and a sealing ring is provided between the splash guard and the cylinder.

[0039] A tool for disassembling and assembling a balance shaft 9 support sleeve 10 for tracked vehicles includes a splash guard 4 and a base 12. A connecting plate 11 is mounted on the base 12, and a support sleeve 10 is mounted on one side of the connecting plate 11. The balance shaft 9 is located inside the support sleeve 10. A cylinder 3 is mounted inside the splash guard 4. The balance shaft 9 is coaxially fitted with the cylinder 3 and is located at the bottom of the cylinder 3. A bearing 2 is located at the top of the cylinder 3. A perforated plate 35 is provided between the bearing 2 and an electric wrench 1. The electric wrench 1 is mounted on the bearing 2. A weight reduction hole 31 is opened on the front side of the cylinder 3. An opening 41 is opened at the top of the splash guard 4, and a cleaning plate 42 is provided at the bottom of the splash guard 4.
[0040] In some embodiments, the upper side of the cleaning plate 42 is a cylinder 3, and the top of the cylinder 3 is provided with a plum blossom groove 33, which is located on the plum blossom plate 35. The bottom of the cylinder 3 is provided with a pin 8, and the inner side of the bottom of the cylinder 3 is provided with a stepped space 34.
[0041] In some embodiments, a retaining ring 21 is provided on the inner side of the bearing 2, and a special disassembly device 6 for rotation is provided inside the cylinder 3. A return spring 7 is provided inside the special disassembly device 6 for rotation. The inner wall of the anti-splash barrel is provided with an energy-absorbing sponge layer 32, which is used to absorb impact energy when the steel ball splashes and prevent the steel ball from rebounding and causing damage.
[0042] In some embodiments, the length of the splash guard 4 is less than or equal to the length of the cylinder 3, and a sealing ring 22 is provided between the splash guard 4 and the cylinder 3. The cylinder 3 is made of plastic material, and the support sleeve 10 is installed outside the balance shaft 9. Mechanical linkage is achieved by inserting 2 to 4 pins 8 at the bottom of the tool into the mating holes of the support sleeve 10. Under the drive of the electric wrench 1, the pins 8 drive the support sleeve 10 to rotate at high speed, thereby throwing out the steel ball inside and achieving the purpose of disassembly.
[0043] Working Principle: The tool comprises several main components, including a splash guard 4, a base 12, a connecting plate 11, a support sleeve 10, a cylinder 3, a bearing 2, an electric wrench 1, a perforated plate 35, a pin 8, a retaining ring 21, and a cleaning plate 42. Its working principle involves the coordinated operation of a series of precisely fitted components to achieve the disassembly and reassembly of the balance shaft 9 and the support sleeve 10. The base 12 serves as the tool's foundation support, providing a stable mounting surface. The connecting plate 11 is mounted on the base and mechanically connected to the support sleeve 10. The position and structure of the connecting plate ensure the stability of the support sleeve 10 during assembly and disassembly, preventing tilting or vibration. The support sleeve 10 supports the balance shaft 9, and its design ensures precise positioning of the balance shaft 9 during assembly and disassembly. The balance shaft 9 is housed within the support sleeve, and through internal mechanical engagement, the balance shaft and the cylinder work together.
[0044] The cylinder 3 is coaxially fitted with the balance shaft 9 and located at the bottom of the balance shaft. The main function of the cylinder 3 is to provide a stable housing space for the balance shaft 9 and to ensure that no misoperation or jamming occurs during the assembly or disassembly of the balance shaft. A weight-reducing hole 31 is provided inside the cylinder; this design helps to reduce the overall weight of the tool and reduce resistance during disassembly. The bearing 2 is installed at the top of the cylinder and is used to support the rotational torque of the electric wrench 1, ensuring that the electric wrench can smoothly transmit power. A retaining spring 21 is provided inside the bearing 2 to fix the bearing's position in the cylinder and ensure the stability of each component during disassembly.
[0045] The electric wrench provides rotational power, which is transmitted to the support sleeve 10 via the capillary plate 35, driving the support sleeve 10 to rotate at high speed. The capillary plate 35 cooperates with the capillary groove 33 to ensure that the electric wrench 1 will not slip or slip during operation. The capillary plate 35 and the capillary groove 33 inside the cylinder connect to form a stable rotation transmission mechanism. The electric wrench achieves high-speed rotation together with the cylinder 3 through the capillary plate 35, effectively driving the support sleeve 10 to perform disassembly.
[0046] The rotating disassembly device 6 is equipped with a return spring 7, which is mainly used to help the support sleeve quickly return to its original position after the disassembly process is completed. This device can rotate under the drive of an electric wrench and use the force of the spring to help the support sleeve 10 return to its initial state for convenient subsequent use.
[0047] The splash guard 4 has an opening 41 at the top to facilitate pressure release when the steel ball is thrown out during disassembly. The inner wall of the splash guard is lined with an energy-absorbing sponge layer 32 to absorb the impact energy generated by the splashing steel ball during disassembly, preventing injury to the operator from the rebounding steel ball. A cleaning plate 42 is installed at the bottom of the splash guard 4 to clean any steel balls and impurities that may remain after disassembly. The design of the cleaning plate ensures cleanliness and maintenance after tool use, extending the tool's lifespan.
[0048] A sealing ring 22 is installed between the splash guard and the cylinder to effectively prevent impurities or liquids generated during disassembly from contaminating the internal structure of the tool, keeping the tool clean and operating efficiently. Driven by the electric wrench, the pin 8 rotates the support sleeve 10, inserting the pin into the mating hole of the support sleeve 10. Through mechanical linkage, the high-speed rotation of the support sleeve is achieved, thereby ejecting the steel ball inside the support sleeve. This design, through mechanical linkage, ensures the smoothness and efficiency of the disassembly process.
[0049] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
