FIELD: building industry, applicable for applicable processing of incongealable surfaces of reinforced-concrete products molded of rigid-concrete mixes for civil and industrial engineering. SUBSTANCE: the disk working member of the smoothing machine with vertical vibrations has a body, electric motor with a lower output shaft connected to a unbalance mechanism installed for engagement with the smoothing disk for transfer of vertical vibrations, a spring located under the unbalance mechanism. According to the invention, it is provided with a plate for fastening of the spring, the unbalance mechanism is made in the form of a drive bevel pinion and two driven bevel pinions with unbalance masses. The electric motor with an additional output shaft coupled to the drive bevel pinion is rigidly connected to the unbalance mechanism. The body is made with guides, the lower shaft of the electric motor is connected to the smoothing disk by means of a coupling and output shaft. EFFECT: enhanced quality of machining of product surfaces. 1 dwg |
