23525-47 The invention relates to the design of gearheads for manipulators which, according to the state of the art, have three axes intersecting at one point. Through this, however, the danger arises that the gearhead can no longer be controlled in its extended position. To avoid this disadvantage, the invention provides for all the axes of the gearhead to be positioned diagonally to one another. Thus the swivelling axis for the rear head piece is never coaxial to the axis of the concentric drive shafts, and that ambiguities in the computer control of the gearhead are thus ruled out. 772-555 str |
