The mechanism of rotation, reducer, drive (without electric motor) - designed to transfer torque from the electric motor to the rotor of the concrete mixer. It consists of cylindrical spur gears (gears, shaft-gears, cog wheels).
Shaft-pinion, pinion - designed to transmit torque from the electric motor to the 1st or 2nd stage of the mechanism of rotation of the concrete mixer.
A toothed wheel, a toothed ring - is intended for transmission of torque in the mechanisms of rotation of the concrete mixer.
Cover, gearbox cover - the protective cover of the reducer housing (rotation mechanism) of the concrete mixer.
The housing (lower), the reducer housing - is the main (bearing) part and is intended for the general assembly of the mechanism of rotation of the concrete mixer.
