Summary

The paper deals with an experimental study of vibration reduction in rotary compressors (horizontally installed) for household refrigerators and other appliances. The vibration of rotary compressors consists of the rotational vibration caused by the speed variation of the shaft, and of the imbalance vibration caused by the mass imbalance in the rotation system. There are various methods for reducing the rotational vibration. The study researched the dynamic damper. It is shown that the dynamic damper, using a helical extension spring applied to the outside of the shell, is effective in reducing vibration.
