FIELD: pendulum movement generation.
SUBSTANCE: invention relates to a device for generating a pendulum movement of a working tool. The device contains a housing, an electric motor, three bevel gears, bearing assemblies, a drive shaft and a driven shaft connected to the working tool. The drive bevel gear is rigidly mounted on the drive shaft, which receives constant rotary motion from the electric motor. Two driven gears, between which the working tool is located, are located on the same axis of the driven shaft, rigidly fixed on it and directed by their teeth towards each other. The leading bevel gear is made with partially removed toothed sectors and the possibility of alternately engaging with one and the other driven gears.
EFFECT: reliability and durability of the device is increased, as well as its design is simplified.
