Belt drive systems: a shock-absorbing solution to counteract gas engine vibrations

The vibration generated by the operation of gas engines will have a serious impact on the performance and service life of the equipment. With its unique shock-absorbing and buffering design, the belt drive system has become a key solution to this problem, providing reliable protection for the operation scene that pursues smooth operation. From the characteristics of elastic rubber materials to the ingenious design of flexible connection structures, belt drive uses a systematic solution to resolve the negative impact of vibration, making the gas log splitter quieter and more stable during operation.
When the gas engine is working, the reciprocating motion of the internal piston and the periodic burst work of the cylinder will inevitably produce vibrations. If these vibrations are directly transmitted to the hydraulic pump, the precision parts inside the hydraulic pump will be subjected to additional impact loads, accelerate the wear process, and shorten the service life of the equipment. Vibration will also cause noise pollution. On the one hand, it will interfere with the working environment of the operator, and on the other hand, high-intensity vibration noise may violate the relevant working environment noise standards. The power loss caused by vibration cannot be ignored. Energy is ineffectively consumed during the vibration transmission process, which reduces the power transmission efficiency and affects the overall performance of the wood splitter.
The belt drive system builds an efficient vibration buffer barrier through elastic rubber materials. Rubber itself has good elastic deformation ability. When the engine vibrates, the belt can deform under the action of force and convert the vibration energy into its own elastic potential energy. This deformation process absorbs most of the vibration energy and greatly weakens the transmission strength of the vibration to the hydraulic pump. The viscoelastic properties of rubber material enable it to slowly release energy after absorbing vibration, avoiding rebound vibration, further improving the shock absorption effect. In order to enhance the durability and transmission performance of the belt, modern belts are usually embedded with high-strength fiber reinforcement layers to improve tensile strength and wear resistance while maintaining elasticity, ensuring that they continue to play a shock absorption role in long-term use.
The belt forms a non-rigid connection between the engine pulley and the hydraulic pump pulley. This connection method allows a certain degree of relative displacement between the two components. When the engine vibrates, the belt can buffer and adjust the vibration transmission between the two pulleys through its own flexibility to avoid direct rigid transmission of vibration. Compared with rigid connection methods such as chain drive, the flexible characteristics of belt drive enable it to better adapt to changes and maintain the stability of power transmission when facing sudden vibration or torque fluctuations. This flexible connection also plays an important role in the moment of starting and stopping the equipment. It can alleviate the instantaneous impact at startup and the inertial vibration at stop, making the equipment run more smoothly.
The advantages of belt drive are fully reflected in scenes with high requirements for noise and equipment stability, such as home courtyards and small wood processing sites. The quiet and stable operation will not interfere with the lives of surrounding residents, reduce the fatigue of operators, and effectively reduce equipment wear, which means lower maintenance frequency and cost, and extend the overall service life of the gas log splitter.
