<p>The spindle rotor pair of the spindle compressor has a 2 toothed spindle rotor (2) and a 3 toothed spindle rotor (3) which engages without contact in terms of teething. The wrap around angle with respect to the 2 toothed spindle rotor is at least 800°. A range of at least 30 m/sec is reached as the medium circumferential speed of the rotor head. Both of the rotors of the spindles of have in the end section circular sections (36.K and 36.F as well as 37.K and 37.F) and cycloidal profile contour edges (38 and 39) which in the case of the 2 toothed spindle rotor (2) are mainly configured above the toothing pitch circle (6) thereof and are of convex configuration and in the case of the 3 toothed spindle rotor (3) are mainly embodied below the toothing pitch circle (7) thereof and in a concave that is to say hollow fashion. The end sections of each spindle rotor are preferably of symmetrical configuration with the result that in each end section the centroid of the profile comes to rest on the respective centre of rotation of the rotor (M.2 or M.3).</p> |
