Vibration attenuator for rotary enclosed motor compressor

Abstract

Abstract PURPOSE:To reduce the vibration in all direction of a compressor by cancelling the torque due to the vibration of the compressor and the counter-torque from a dynamic vibration absorber. CONSTITUTION:In order to match with the rotary frequency of the compressor or the power source frequency, the dynamic vibration absorbers 4, 5 arranged in an enclosed container 1 will vibrate with the vibration of the compressor and the reverse phase. Consequently the torque due to the vibration of the compressor and the counter-action torque to be fed from the dynamic vibration absorbers 4, 5 are cancelled to provided the nod of the vibration, thereby each dynamic vibration absorbers 4, 5 will form the nod of vibration at two different points of the compressor thus to reduce the vibration in all directions of the compressor.
