Time-Varying Load Analysis on the Rotor-Bearing System for Twin-Screw Compressors

Abstract:

Shaft and rotor deformation caused by the high pressure load, temperature and other external forces in the twin-screw compressor may produce flow leakage, tooth wear and bearing failure. A time-varying load analysis procedure is proposed in this paper to obtain the gas torques on rotors, bearing forces and the shaft deflections for the twin-screw compressor. Further, the calculated forces are compared with the existed well-known software to verify the correctness of the proposed method. Also, the forces on each bearings and the shaft deflection are predicted through KISSsoft modeling technique in this paper.
