A VIBRATION ABSORBERPREVENT OF BREAKER

摘要

A vibration absorber of a breaker is provided to reduce the vibration and noise of a breaker, to prevent the instable phenomenon of a breaker caused by excessive vibration and to extend the life of a breaker by attaching masses to a vibration-proof cushion vibrating at fixed frequency and making the natural frequency of a vibration absorber equal to the frequency of a vibrator. As a vibration absorber of a breaker, a vibration-proof cushion is installed on the upper part of a bracket installed on the upper part of a main body of a breaker to absorb the vibration and noise caused by hitting the breaker easily, wherein cushion layers made of urethane are formed on the upper and lower parts of the vibration-proof cushion and masses made of steel are piled between the upper cushion layer and the lower cushion layer in a thickness ratio of 1 to 1 to 1 to make the natural frequency of the vibration absorber equal to the frequency of a vibrator to reduce the vibration of the vibrator, and circular projections are formed on two upper sides of the upper cushion layer to make the vibration-proof cushion situated and fixed to the breaker effectively and made of engineering plastics to keep coupling strength.
