DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Reference Figures 1-3 The overall structure of the wheel shaft rotary support pad sleeve is mainly composed of two core components: a sleeve ring 1 and a wheel shaft 5. The sleeve ring 1 serves as an external support frame, with an upper annular cavity 7 and a lower annular cavity 14 carefully arranged inside. These two annular cavities, like the "secret compartments" of precision instruments, each has its own function and contains the key mechanism that drives the efficient operation of the entire pad sleeve.

[0023] In the upper annular cavity 7, two screw rods 9 and a vertical shaft 10 are suspended by a stable hoisting frame 8. The hoisting frame 8 adopts a U-shaped design, which perfectly fits the horizontally arranged screw rods 9 and the vertically standing vertical shaft 10, ensuring that the three remain firmly connected in complex mechanical environments, laying a solid foundation for subsequent precise transmission.

[0024] The screw rods 9 and the vertical shaft 10 are connected through a set of precise transmission mechanisms. The core components of the transmission mechanism are the driving gear 11 installed on the vertical shaft 10 and the transmission gear 12 installed on the screw rod 9. The driving gear 11 is a circular gear, while the transmission gear 12 is a conical gear. The precise meshing design of the two gears enables the rotational motion of the vertical shaft 10 to be accurately and efficiently converted into the linear displacement of the screw rod 9. When the vertical shaft 10 rotates, the screw rod 9 rotates synchronously under the drive of the gear meshing, thereby driving the subsequent components to perform precise positioning operations.

[0025] The two screw rods 9 are respectively threaded with a fixed frame 2 and a positioning frame 3. Both components are L-shaped, with their vertical parts closely fitting the screw rods 9 and achieving precise lifting control through threaded connection; the horizontal parts extend outward to the outside of the sleeve ring 1, making them play a key role in the connection process between the pad sleeve and the external structure.

[0026] To ensure the precise linear motion trajectory of the fixed frame 2 and the positioning frame 3 during the rotation of the screw rod 9, a limit rod 13 is also arranged in the upper annular cavity 7. The limit rod 13 is arranged in parallel with the screw rod 9 and slides through the fixed frame 2 and the positioning frame 3, acting like a guide wheel on a track, strictly constraining their movement direction and preventing any possible deviation or shaking, ensuring the accuracy and repeatability of each positioning operation.

[0027] The wheel shaft 5 is provided with a ring-shaped positioning groove 6 corresponding to the positioning frame 3. When the pad sleeve is assembled, the positioning frame 3 is driven to move down precisely by the rotation of the screw rod 9, allowing it to stably embed into the ring-shaped positioning groove 6 of the wheel shaft 5, achieving a tight and reliable connection between the sleeve ring 1 and the wheel shaft 5, and providing solid structural support for the stable rotation of the wheel shaft.

[0028] The double-sided gear ring 16 is rotatably arranged in the lower annular cavity 14, and is like a hidden "power center" in the dark, receives driving instructions from the outside, and converts the driving instructions into internal linkage energy.

[0029] The outer sleeve 1 is provided with a driving motor 4, which is a power source of the whole sleeve system, and is connected with the double-sided gear ring 16 through a set of well-designed rotating mechanism. The key part of the rotating mechanism is a rotating gear 15 installed on the output shaft of the driving motor 4, which is directly engaged with the double-sided gear ring 16. When the driving motor 4 is started, the output shaft drives the rotating gear 15 to rotate, and the double-sided gear ring 16 is smoothly and smoothly rotated in the lower annular cavity 14.

[0030] The vertical shaft 10 is connected with the double-sided gear ring 16 through a set of engaging mechanism. The engaging mechanism is mainly composed of an engaging gear 17 installed on the vertical shaft 10, which is also engaged with the double-sided gear ring 16. In this way, when the double-sided gear ring 16 rotates under the action of the driving motor 4, part of the power can be transmitted to the vertical shaft 10 through the engaging gear 17, realizing a clever power circulation and synergistic effect, and further optimizing the adaptability of the sleeve under complex working conditions.

[0031] The mounting hole is specially arranged on the vehicle body for mounting the sleeve 1, and the inner wall of the mounting hole is designed with a fixing groove corresponding to the fixing frame 2. In the actual installation process, the sleeve 1 is aligned with the mounting hole, and then the horizontal part of the fixing frame 2 is smoothly slid into the fixing groove on the inner wall of the mounting hole, so that the sleeve and the vehicle body are conveniently and stably connected.

[0032] At the same time, the sleeve 1 is connected with the wheel shaft 5 through the precise positioning of the positioning frame 3, and the assembly of the whole wheel shaft rotary support sleeve is completed, which greatly simplifies the installation process and reduces the maintenance cost, and provides a powerful guarantee for the efficient operation of the wheeled equipment.

[0033] The utility model installs state: the sleeve 1 is in the vehicle body, the wheel shaft 5 is in the sleeve 1, the fixing frame 2 is in the fixed groove of the mounting hole of the vehicle body, and the positioning frame 3 is in the annular positioning groove 6.

[0034] When a plurality of components are disassembled: the driving motor 4 is started and drives the rotating gear 15 to rotate, the rotating gear 15 drives the double-sided gear ring 16 to rotate, the double-sided gear ring 16 drives the vertical shaft 10 to rotate through the engaging gear 17, the vertical shaft 10 drives the screw 9 to rotate through the driving gear 11 and the transmission gear 12, and the screw 9 moves when rotating, and the fixing frame 2 and the positioning frame 3 are separated from the fixed groove and the annular positioning groove 6, so that the installation of the sleeve 1 relative to the vehicle body is removed, and the installation of the wheel shaft 5 relative to the sleeve 1 is removed.

[0035] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
