A threaded rubber vibration damper is a standardized mechanical component formed by vulcanizing and bonding metal threaded parts to elastic rubber. Commonly used for vibration isolation in electromechanical, automotive, and aerospace equipment, it absorbs and attenuates vibration and shock through the elastic deformation of the rubber, thereby protecting equipment precision and reducing noise. Common configurations include metal threads at both ends; based on installation requirements, they are categorized into several common types: VV type (dual male threads)-male threaded studs at both ends, facilitating elevated mounting; VD type (male and female threads)-a male threaded stud at one end and a female threaded hole at the other; and DD type (dual female threads)-female threaded holes at both ends, connected via threaded rods. Core materials and features: The body is typically made of high-strength natural rubber (with nitrile or silicone rubber used in specialized environments for oil and high-temperature resistance), with internal metal components such as carbon steel. Key characteristics include excellent dynamic cushioning performance and stability under lateral (sideways) forces. Selection and application: These dampers often serve as adjustable leveling feet or cushioning components for air compressors, water pumps, generators, control cabinets, and electronic instruments. When purchasing, specific selection should be based on the equipment's load-bearing requirements, installation thread specifications (e.g., M3, M5, M8), and the operating environment (e.g., the need for oil or high-temperature resistance).
