FIELD: heavy engineering industry. SUBSTANCE: the device uses heating chamber 1. Commutator 2 is fastened on the mandrel of core 3. Chamber 1 has a detachable part. Rotational speed of electric drive 5 is monitored by transducer 6. Transducer 8 measures the vibration level of the installation. Transducer 10 transmits information to the balancing device with indicator 11. Sensitive element 12 serves for measurement of commutator temperature with indication on meter 13. Sensor 14 serves for contactless monitoring of commutator integrity with recording of indications on oscillograph 15. Brake 16 serves for fixing the position of core 3 at the instant of tightening of the nuts of commutator 2. EFFECT: enhanced quality of commutators. 1 dwg
