ZAHNRINGMASCHINE MIT ZAHNLAUFSPIEL

摘要

The annular gear machine has an inner gearwheel (1) with external teeth (1a) meshing with internal teeth (2i) on a second gearwheel (2) with a pitch circle axis (D2) eccentric to the rotational axis of the inner gearwheel. The intermeshing teeth have a radial (PR) and a tangential gear running clearance, with the tangential clearance smaller than the radial clearance. The profile of the tooth points or tooth roots of the teeth is formed by or from the locus curve of a point on the circumference of a pitch circle, the radius of which steadily decreases or decreases from the flank regions to the apex region. An Independent claim is included for a gear set for an annular gear machine of the displacement type.
