Abstract

A drive device (10) for a forming machine (11) includes a hypocycloid gear assembly (20) having an eccentric gear (23), a stationary annulus gear (24) and a planetary gear system (28). The planetary gear system (28) includes an orbiting gear (29) orbiting and rolling in an annulus gear (24). The orbiting gear (29) is connected to at least one first planetary gear (35). On the first planetary gear (35), a first planetary gear equalization mass (m2) is disposed diametrically opposite an output bearing. At least one first eccentric gear equalization mass (m3) is arranged on the eccentric gear (23). The first eccentric gear equalization mass (m3) is arranged diametrically opposite, relative to a planetary gear axis (PA) about which the planetary gear system (28) rotates. The resultant forces and torques acting on the annulus gear (24) can at least be reduced by the equalization masses.
