BALANSERINGSANORDNING FOR ROTERANDE KROPP

摘要

A balancing device and method for balancing a rotating body during operation. The device and method detects the phase and amount of unbalance and provides signals in synchronism with the unbalance. Local heating of the rotating body is provided to counteract the unbalance by thermal deformation of the axis of the body without removing material. The phase and amount of the local heating are controlled in relation to unbalance detected.
