Dynamic unbalance elimination appts. for rotor - uses response sensor for automatic determination of unbalance and laser oscillator to heat correcting position

摘要

Dynamic unbalance elimination appts. is for a rotor during rotary motion. It uses response detector or sensor (23) for automatic determination of unbalance of rotor (27). The correcting position is heated up by means of a laser oscillator (21), and an oxidator is fed by means of an oxygen blast nozzle (30) to the correcting position. The heating-up (21) and feeding devices (30) are guided by a controller (22) in response to the output signal (29) of the detector or sensor (23) when a laser beam (28) is emitted. The laser beam (28) is focussed onto the rotor (27).
