The invention relates to the field of mechanical engineering and can be used in machine tools, in particular in the drive of forging and pressing mechanical machines

A known planetary gear comprising a housing, a carrier, a twin-gear satellite, a fixed central gear wheel with internal gear attached to the housing, and a central gear wheel with internal gear engaged with the satellite.

In this gear, there are friction losses in two gears, and only the second central wheel has a changed output speed.

A K-H-V transmission is also known, comprising a housing, carrier, an output shaft and a central wheel connected to it, a satellite.

Since it has one output shaft, its kinematic capabilities are reduced.

The aim of the invention is to expand the kinematic capabilities by increasing the number of output shafts.

This goal is achieved in that the planetary gear comprising a housing, carrier, an output shaft, a central wheel and a satellite connected to it, is provided with at least one additional output shaft and a central wheel, and additional crowns are made on the satellite, the number of which is equal to the number of additional output central wheels.

Fig. 1 is a kinematic diagram of a transmission having an internal gearing satellite; Fig. 2 is an embodiment of a transmission in which the satellite is an external gearing wheel.

The device comprises a housing 1, in which the in-phase main 2 and additional carrier 3 with the same radius of the cranks on which are installed

satellite 4, bearing gears according to the number of output shafts.

The satellite 4 is engaged with one wheel 5 or with a large number of central wheels 6, 7, while the gears can be coaxial (5, b) or misaligned (5, 7).

Additional carrier 3 is associated with the main 2 belt or other transmission or

driven by a separate motor (not shown).

In the process of planetary gear operation, satellite 4 performs a plane-parallel circular motion of a constant

radius due to the in-phase rotation of carrier 2 and 3. Gear ratios are defined as pl. f (in) by known methods, taking this fact into account, the rest of the transmission does not differ from the operation of known planetary gears.

If in the transmission the satellite 4 is made in the form of a wheel with external gearing (Fig. 2), the in-phase rotation of the carrier 2, 3 tells the satellite a plane-parallel circular motion, which drives the central wheels 5, 6, 7.

The transmission has kinematically enhanced capabilities by increasing the number of output shafts, the presence of one

meshing provides a reduction in friction losses, as a result of which its efficiency is increased.
