Embodiment Construction
[0034] figure 1 A schematic illustration of the movement of the eccentric worm 105 is shown. In contrast to rotary piston pumps which have two moving rotor parts (as are found, for example, in gear pumps or gear helices), wherein the rotor parts only perform a rotational movement about their own axis and Correspondingly simple to mount and drive), in the eccentric worm pump 101 the eccentric worm 105 performs, in addition to its own rotation about the axis of symmetry 107 , an additional movement on the cylindrical housing that is superimposed on this rotation. The isolated rotational motion in the figure 1 is shown by circular orbits in the x-y plane. The rolling motion superimposed on the rotary motion causes a resultant motion of the eccentric worm 105 which in figure 1 The center is marked by multiple single arrows on a circular orbit. Preference is given here to a configuration based on a 2:1 hypocycloid, in which the rotational frequencies are opposite and result in ...
