Application of buffer Springs in Excavator Shock Absorption Systems
Buffer springs in the shock absorption system of excavators are mainly used to absorb operation shock, suppress vibration and protect key structures, ensuring the stability and durability of the equipment under harsh working conditions . Its application covers multiple dimensions, as follows:
⚙️ I. Core application scenarios of
Track tensioning device : Buffer springs are installed in the track system to absorb dynamic impacts during driving or excavation (such as jolts in ore mining) through elastic deformation, preventing the track from loosening or derailing. Meanwhile, the pre-tightening design of the spring can maintain the tension of the track and reduce the risk of screw breakage or lock nut loosening caused by impact .
Suspension shock absorption system : At the connection points of the excavator chassis or boom, springs and hydraulic dampers work in coordination. They first convert the impact kinetic energy into elastic potential energy for temporary storage, and then convert the damping friction into heat energy for dissipation, thereby avoiding damage to components such as bearings and gears caused by rigid collisions .
II. Key Points for the installation and Debugging of
The installation of buffer springs directly affects the shock absorption performance and must follow strict procedures:
Preparations : Use a jack to lift the main body of the excavator to ensure stability, check the direction of the spring (such as aligning the opening with the pallet clamp) and ensure that the new parts are not deformed or damaged; Tools should include special equipment such as wrenches and screwdrivers .
Precise installation : when removing the old spring, avoid damaging the oil seal. The new spring should be fully embedded in the slot and in contact with the mudguard. After installation, spray lubricant to reduce friction and ensure the levelness by adjusting the bolts to prevent the vehicle from being uneven or making abnormal noises due to skewing .
Commissioning and maintenance : During commissioning, test each shock absorption unit in sequence and adjust the air pressure to stabilize the rebound height; Regularly check the sealing performance of the pipeline and the condition of the spring. The load should not exceed 20%-30% of the rated value to avoid overloading or high-temperature environments affecting the service life .
III. Performance Advantages and benefits of
Extend equipment life : Springs reduce impact force by over 70% through elastic energy storage, lowering fatigue damage to key components; High-strength alloy material (surface quenched hardness up to 52-60HRC) supports over 500,000 cycles and is suitable for high-load scenarios such as mining and metallurgy .
Noise reduction and stability : By combining rubber shock-absorbing pads to absorb high-frequency vibrations, the penetration of low-frequency noise is reduced by 30%. After installation optimization, the wear rate of sediment intrusion can be reduced by more than 40%, and the operational comfort is improved .
In conclusion, the buffer spring, with "energy conversion + structural optimization" at its core, provides efficient shock absorption and protection for excavators .
