ABSTRACT:
A micro gear system, operating according to the principle of a strain wave gear system, a Wolfrom gear system, or a similar planetary gear system comprises at least one sun wheel (14) and at least two planet wheels (16) meshing with the sun wheel (14). The sun wheel (14) is rotatably fixed to drive shaft (20) placed along a longitudinal axis (18) of the gear system. The planet wheels (16) indirectly or directly mesh with a toothing which is rotatably fixed to a drive shaft (28) placed centrally along the longitudinal axis of the gear system. The drive shafts (20,28) are embodied as hollow shafts (30,32) having continuous bore holes (34,36) such that information or fluid media can be directed through the gear system. A sealing system (42) comprising a labyrinth seal (44) which includes a plurality of annular grooves (46) is disposed between the hollow shafts (30,32).
