摘要(英)

The key component in twin-screw fluid machines is a pair of screw rotors, which rotate parallelly around the respective axis in the opposite directions. Two meshing rotors may be with or without contact. Design on rotor profiles to form a better meshing clearance band is a main factor to affect the machine performance. In the practical application, it is difficult to measure the clearance distribution between the surfaces of meshing screw rotors due to the variety in rotor types and the large curvature variation on rotor profiles. In view of this, this study proposes a general numerical method to evaluate the meshing clearance for twin-screw rotor pairs. Discrete point data of rotor profiles obtained from the theoretical design or the 3-D coordinate measuring machine (CMM) is used to conduct the meshing clearance analysis and the 3-D clearance presentation along the contact line, after being classified into the conjugated and non- conjugated profile segments. The fluid leakage band can thus be presented more intuitively. In addition, a pair of conjugated rotor profiles without clearance is able to generated by correcting the calculated result of meshing clearance. As results shown in the numerical examples, correctness of the proposed method is verified through several cases of rotor profiles with different tooth profiles and different leads. It is also proved that this method is suited to calculate the meshing clearance considering the assembly error of rotors.
