[0043] Working principle:
[0044] Power is first input to the lock differential gear combination gear system through the bevel gear 4. The bevel gear 4, as a power receiving component, can transmit external power to the transmission rod 5 at an appropriate direction and angle. Since a buffer damping structure composed of an elastic gasket and a damping material layer is arranged at the connection part of the bevel gear 4 and the transmission rod 5, the vibration and impact generated by mechanical operation will first pass through this buffer damping structure when power is transmitted. The elastic gasket absorbs part of the vibration energy through its elastic deformation, and the damping material layer converts the vibration energy into heat energy and consumes it, thereby effectively reducing the vibration and impact transmitted to the transmission rod 5, protecting the transmission rod 5 and other related components, prolonging their service life, and improving the operation stability and reliability of the entire system.
[0045] The power after buffering and damping is transmitted to the transmission rod 5. The transmission rod 5 is provided with annularly arranged keyways 2, which allows the power to be evenly distributed to each component connected thereto. The transmission rod 5, as a power transmission hub, further transmits the received power to subsequent components.
[0046] The clutch plate 3 is sleeved on the transmission rod 5 and is connected with the transmission rod 5 through a pin key. The limiting effect of the pin key makes the clutch plate 3 and the transmission rod 5 form a rigid connection. When the transmission rod 5 rotates, the clutch plate 3 will rotate synchronously. The plurality of clutch plates 3 are installed equidistantly on the transmission rod 5 through the limiting block 7, and the spacing between the clutch plates 3 is uniform. In the working process, the clutch plates 3 are combined or separated according to actual needs to realize the transmission and interruption control of power. When the clutch plates 3 are combined, the spacing between the clutch plates 3 is uniform and the clutch plates 3 rotate synchronously with the transmission rod 5, so that the clutch plates 3 can bear force uniformly and stably transmit power.
[0047] The clamps 6 are installed on the transmission rod 5 and are distributed crosswise with the clutch plates 3. The clamps 6 are clamped with the protrusions 701 on the limiting block 7 through the clamping grooves to limit the limiting block 7. The limiting block 7 is installed in the key groove 2 and plays a role in clamping and fixing the clutch plates 3. The two ends of the clamps 6 are connected through bolts to form a closed ring structure and tightly clamp the transmission rod 5. When the equipment operates and generates vibration or impact, the clamps 6 can effectively limit the movement of the limiting block 7, and through the cooperation of the clamping grooves and the protrusions 701, the limiting block 7 is firmly fixed in the key groove 2, so that the installation position of the clutch plate 3 is fixed, and the stability of power transmission is ensured.
[0048] The connecting sleeve 1 is sleeved on the end of the transmission rod 5 and is connected with the transmission rod 5 through a bolt. The bolt tightly connects the connecting sleeve 1 and the transmission rod 5 together to form a whole, which enhances the structural strength and stability of the system. The connecting sleeve 1 further fixes the structure of the whole system, prevents the loosening or displacement of each component under high-speed operation or complex working conditions, and ensures that power can be reliably transmitted in the system.
