Abstract
A swivel head for industrial robots has two degrees of freedom, which are associated with respective spindles having intersecting axes. A first spindle serves to swivel a tool and a second spindle serves to rotate the tool. The swivel head also comprises two concentric drive shafts, which extend one in the other and carry bevel gears. One of said bevel wheels is a driving bevel gear for directly driving the second spindle by means of a bevel gear mounted on said second spindle. The other bevel gear drives a swiveling bevel gear mounted on the first spindle. In that swivel head a speed-reducing tansmission having a high reduction ratio is connected to the second spindle and serves to drive a tool carrier. The swiveling bevel gear directly carries a bearing bracket, which carries the tool shaft and intermediate gears of the transmission. The housing of the swivel head consists of a rigid part and a movable part.
