Abstract

With increasing demands for high-speed and high-precision machining technology, how to improve the efficiency and precision of the workpiece is an important subject. In this paper, the tooth profile errors of screw rotors induced by manufacturing errors and wears as well as mounting errors of grinding wheel are studied. Mathematical models of the profile errors of screw rotors are established and the influence curves of the tooth profile errors affected by mounting errors and the radius error of grinding wheel are proposed. Error analysis of precision grinding for screw rotors is proposed. The experiment and error compensation for screw rotors are performed. It is helpful for improve grinding accuracy of screw rotors and laid a good foundation for error compensation of precision grinding of screw rotors and other helical surface.
