PHASE-LOCAL CONTACT OF TEETH OF SCREW COMPRESSOR
Machulda V., Švígler J.
pages 148 - +10p., full text

This contribution is devoted to screw compressors with injection, where tooth surfaces provide kinematic and force coupling between rotors. In theoretical case axes of both rotors are parallel. Under influence of operating loading, which is composed of force field, temperature field and dynamic activities, the parallel arrangement of rotor axes changes into skew position and a curvilinear correct contact between tooth surfaces of rotors changes into the incorrect contact at point. Aim of this contribution is determination of the position of the contact point between two conjugated screw surfaces by skew arrangement of rotors axes in time period.
