Abstract
Дисковый рабочий орган бетоноотделочной машины, содержащий приводной вал, который имеет возможность передавать крутящий момент на заглаживающий диск, отличающийся тем, что в углублениях заглаживающего диска расположены электромагниты, создающие магнитное поле, электропитание на которые подается посредством скользящих контактов через реостат, с помощью которого имеется возможность регулировать градиент магнитного поля.A disk working element of a concrete-finishing machine containing a drive shaft, which has the ability to transmit torque to a smoothing disk, characterized in that in the recesses of the smoothing disk there are electromagnets that create a magnetic field, the power of which is supplied through sliding contacts through a rheostat, with which it is possible adjust the gradient of the magnetic field.
