Basic theoretical study of dynamic and static pressure floating ring electric spindle

electric spindle;  dynamic and static pressure floating ring;  Finite elements

Aiming at the problems of severe wear, unstable machining accuracy and short service life of the traditional rolling support of the electric spindle, the dynamic and static pressure floating ring support is proposed to improve the vibration resistance, rotation accuracy and reduce the production cost of the spindle system. The finite element calculation of the proposed dynamic and static pressure floating ring support is carried out, part of the static characteristics are analyzed, and an experimental research scheme is proposed, which lays a theoretical foundation for further and more comprehensive study of the spindle system.
