Description

Technical Field

[0001] This utility model relates to the field of track machine base manufacturing, and in particular to a track machine base that is easy to maintain. Background Technology

[0002] The track machine base is an important component of tracked machinery. It bears the weight of the entire machinery and transmits power and controls motion through components such as gears and motors.

[0003] Traditional tracked vehicle bases are typically constructed from multiple components welded or bolted together, resulting in a complex structure that is difficult to disassemble. When maintenance or component replacement is required, significant time and effort are often spent on disassembly and reassembly, increasing maintenance costs and downtime. Some models also require operation from the bottom of the machine, which restricts the operating space and makes maintenance inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a track machine base that is easy to disassemble and maintain.

[0005] The purpose of this utility model is achieved as follows: an easy-to-maintain tracked machine base includes a housing, a gear disk, and a motor. The housing is composed of a side plate, a top plate, and a bottom plate. The top plate has an opening in the center, and a rotating shaft is installed in the opening. The rotating shaft is connected to the top plate and the bottom plate through bearings. A gear disk is connected to the top of the rotating shaft, and the gear disk is connected to the upper vehicle body base. A support frame is provided between the top plate and the bottom plate. A semi-circular notch is provided on one side of the top plate, and a first fixing plate extends downward from the semi-circular notch. A circular limiting plate is provided at the upper part of the motor, and a second fixing plate extends downward from the circular limiting plate along the central axis. The second fixing plate and the first fixing plate are fixedly installed by bolts.

[0006] Preferably, the inner diameter surface of the semi-circular notch is provided with a V-shaped groove, and the outer periphery of the circular limiting plate is V-shaped, so that the circular limiting plate is embedded in the V-shaped groove to achieve a fit.

[0007] Preferably, the bottom plane of the gear disk is provided with an annular limiting groove, and the top plane of the top plate is provided with an annular limiting protrusion, and the annular limiting protrusion and the annular limiting groove are engaged.

[0008] Preferably, the motor has a base at its bottom, and the base is connected to the base plate by bolts.

[0009] Preferably, the side plate on the side where the motor is located is provided with an operating hole.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. The motor is connected to the circular limiting plate and the second fixing plate, which in turn cooperate with the semi-circular notch and the first fixing plate. This allows the motor to be easily disassembled and installed when it needs to be repaired or replaced. It can be taken out directly from the outside of the machine body without the need for operators to operate from the bottom of the machine body, which further simplifies the installation and disassembly process of the motor.

[0012] 2. An operating hole is provided on the side plate on the side where the motor is located, which makes it convenient for maintenance personnel to install, fix and adjust the motor without completely disassembling the housing;

[0013] 3. The V-shaped groove on the inner diameter surface of the semi-circular notch matches the V-shaped outer periphery of the circular limiting plate, so that the main body of the motor can be limited by the top plate, improving the stability after installation.

[0014] 4. The annular limiting groove on the bottom plane of the gear disk and the annular limiting protrusion on the top plane of the top plate are matched to enhance the stability and positioning accuracy of the gear disk and ensure the smooth operation of the transmission system.

These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.

[0023] like Figure 1-4 As shown, an easy-to-maintain tracked vehicle base includes a housing 1, a gear disk 2, and a motor 3. The housing 1 is composed of a side plate 101, a top plate 102, and a bottom plate 103. The top plate 102 has an opening 1021 in the center, and a rotating shaft 4 is installed in the opening 1021. The rotating shaft 4 is connected to the top plate 102 and the bottom plate 103 through bearings. The top of the rotating shaft 4 is connected to the gear disk 2, and the gear disk 2 is connected to the upper vehicle body base. A support frame 5 is provided between the top plate 102 and the bottom plate 103. A semi-circular notch 1022 is provided on one side of the top plate 102, and a first fixing plate 1023 extends downward from the semi-circular notch 1022. A circular limiting plate 301 is provided at the upper part of the motor 3. A second fixing plate 302 extends downward from the circular limiting plate 301 along the central axis. The second fixing plate 302 and the first fixing plate 1023 are fixedly installed by bolts.

[0024] like Figure 2-3As shown, a V-shaped groove 10221 is provided on the inner diameter surface of the semi-circular notch 1022, and the outer periphery of the circular limiting plate 301 is V-shaped. The circular limiting plate 301 is embedded in the V-shaped groove 10221 to achieve a fit; this further enhances the connection stability between the motor and the housing, helps to reduce loosening caused by vibration or impact, and improves the durability and reliability of the entire device.

[0025] like Figure 4 As shown, the bottom plane of the gear disk 2 is provided with an annular limiting groove 201, and the top plane of the top plate 102 is provided with an annular limiting protrusion 1024. The annular limiting protrusion 1024 and the annular limiting groove 201 are engaged to ensure the stability and accuracy of the gear disk, help prevent noise and wear caused by loosening, and improve the transmission efficiency and life of the entire device.

[0026] like Figure 1 As shown, the bottom of the motor 3 is provided with a base (not shown in the figure), which is connected to the base plate 103 by bolts to ensure the stability of the motor after installation.

[0028] The working principle of this utility model is explained as follows: The motor serves as the power source, connected to the semi-circular notch on the housing and the first fixed plate via a circular limiting plate and a second fixing plate. When the motor operates, it drives the gear disc to rotate via the drive shaft, thereby driving the tracked machinery forward or backward. A V-shaped groove is provided on the inner diameter surface of the semi-circular notch, which cooperates with the circular limiting plate above the motor for a more stable connection. Furthermore, an operating hole is provided on the side plate on the side where the motor is located, facilitating maintenance and adjustment by the operator. The entire design embodies ease of maintenance, ensuring efficient operation and reliable maintenance of the tracked machinery.
