Specific embodiment
With reference to embodiment, the invention will be further described, but protection scope of the present invention is not limited solely to reality
Apply example.
High-power threephase asynchronous motor drives the rotation of driving shaft by toothed belt transmission, then by the engagement band of gear
The rotation of dynamic large eccentricity mechanism, allows exciting gear-box produce the low-frequency vibration of large amplitude, so that the raw large amplitude of pendulum is low
The vibration of frequency.Small-power triphase asynchronous motor drives the rotation of driving shaft, then nibbling by gear by toothed belt transmission
Crossed belt moves the rotation of small eccentricity mechanism, allows exciting gear-box produce the vibration of little amplitude and high frequency rate, so that pendulum life is little shaking
High-frequency vibration.When size eccentric stiffener runs simultaneously, pendulum will generate low-and high-frequency and meet vibration.
