Contact of screw machine rotors under operate loading
Original language description
Rotors of a liquid injected screw machines create a pair of conjugate screw surfaces that touch mutually. Force and temperature loading of the screw machine housing causes a change in an arrangement of the rotor axes. An originally parallel ordering changes into a space arrangement with the skew axes. This change causes a variation of the character of contact of tooth surfaces. The curve contact degenerates into the point contact. The change of the surface contact produces another phenomenon such as arise of undesirable gaps between tooth surfaces, change of the gear ratio and static and dynamic stress of surfaces. Presented contribution analyses the incorrect contact of screw surfaces of the rotors in detail. Problem is solved as a three-dimensional case.
