Application of buffer Springs in Excavator Shock Absorption Systems
The core application and technical key points of buffer springs in the shock absorption system of excavators are as follows:
️ I. Core functions and scenarios
Automatic track tensioning system
The hydraulic spring buffer works in coordination with the hydraulic telescopic rod to monitor and automatically adjust the track tension in real time, avoiding the risk of derailment caused by manual adjustment errors.
Elastic deformation absorbs over 70% of the impact kinetic energy (such as the impact of ore jolting), protecting the track screw and lock nut, and reducing the risk of fracture .
Suspension shock absorption structure
The combination of springs and hydraulic dampers converts the impact kinetic energy into elastic potential energy for temporary storage, and then converts the damping friction into heat energy for dissipation , preventing the chassis bearings and gears from being damaged due to rigid collisions .
High-strength alloy materials (hardness 52-60HRC) can support over 500,000 cycles and are suitable for heavy-load working conditions in mines .
II. Key technologies for installation and commissioning
Precise installation process
Pre-operation : Stabilize the body of the jack, check the direction of the spring (align the opening with the pallet clamp) and ensure there is no deformation or damage ; When disassembling old parts, protect the integrity of the oil seal .
Positioning requirements : The new spring must be fully embedded in the slot, closely attached to the mudguard, and the bolts should be calibrated horizontally to avoid deviation and abnormal noise .
Debugging and maintenance specification
Check each shock absorption unit in sequence and adjust the air pressure to control the rebound height ; The load shall not exceed 30% of the rated value .
Regularly check the sealing of the pipeline and remove the adhesion of sediment (reducing wear by more than 40%) .
III. Synergistic design
Material and structural innovation
The rubber-spring composite structure absorbs high-frequency vibrations (energy rebound rate <15%) and reduces the penetration of low-frequency noise by 30%.
Polyurethane buffers are corrosion-resistant and suitable for high salt spray environments in ports .
System linkage protection
The three-dimensional heat conduction channel enhances the heat conduction efficiency of the rubber pad by 3 times (up to 0.75W/m·K) and delays high-temperature aging ;
The adaptive hydraulic system regulates pressure according to the load to maintain the optimal shock absorption state .
▶️ comprehensive value
The buffer spring achieves triple optimization through the "elastic energy storage → damping energy dissipation" mechanism:
Extended lifespan : 80% reduction in impact damage, fatigue resistance life exceeding industry standards;
Noise reduction and efficiency enhancement : high-frequency vibration attenuation by 40%, improved operational comfort;
Intelligent maintenance : The automatic tensioning system reduces the frequency of manual intervention by 50%.
