Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a composite rubber shock absorber. Background Technology

[0002] In fields such as machinery manufacturing, precision machining, and automated equipment, vibration and impact can severely affect processing accuracy, operational stability, and service life. Therefore, vibration dampers, as key fundamental components, are of paramount importance. Currently, common vibration dampers on the market mainly include pure rubber dampers and metal spring dampers. While existing rubber dampers can isolate high-frequency fine vibrations, their damping characteristics are limited. When dealing with large, high-energy impact loads, their energy dissipation capacity is insufficient, easily leading to severe shaking or slow recovery of the equipment, resulting in poor stability. Metal spring dampers, while capable of handling large impacts, have poor isolation effects on high-frequency vibrations, easily generating resonance phenomena with high transmission rates, and also producing significant noise, making it difficult to meet the comprehensive vibration damping requirements under complex working conditions. Existing vibration dampers have installation direction requirements; improper installation can affect the damping effect. Furthermore, their fixed structure makes it difficult to flexibly adjust stiffness and load-bearing capacity, lacking modular design and unable to quickly adapt to equipment of different weights and vibration damping requirements, resulting in poor versatility. Utility Model Content

Through various structural improvements, the rubber bolt holes and metal bolt holes are designed to mate, providing an elastic composite connection structure for the shock absorption mechanism.
