FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering. The device for reverse rotation of the working tool contains a housing, an electric motor, bevel gears, bearing assemblies, a drive shaft, a driven shaft connected to the working tool. On the output shaft, the device additionally contains a block of three bevel gears. Two driving gears are rigidly fixed on the drive shaft and are directed towards each other from the teeth, a driven shaft is located perpendicular to the drive shaft, at one end of which a driven bevel gear is rigidly fixed, which lacks a part of the toothed sectors that is engaged with two driving gears, and at the other end the working tool with the possibility of reverse rotation is installed.
EFFECT: simplification of design and the increase of the device’s reliability is provided.
