DEVICE FOR MODIFYING THE CRITICAL ROTATION SPEED OF MACHINES

摘要

Exchangeable elastic elements having an adaptable spring property which are installed in recesses provided in at least fastening part of a casing member for compensation in critical speed operation of vertical groups of machines. Compensation for critical speed operation of a mounted machine is possible by exchanging elastic elements or by changing the number of elastic elements utilized. The exchangeable elastic elements may include at least one borehole formed therewithin and within which a fastening element is disposed. The exchangeable elastic elements may be composed of different materials or have different spring properties and may also be designed as slide-in parts for insertion within the recesses provided in the at least one fastening part of the casing.
