Performance Analysis of Hydrostatic Slideways Systems with Different Types of Restrictors

Abstract:

In fluid hydrostatic closed-type slideways systems, restrictor will take an important role of improving the performance of machine tools. Generally there are four types of restrictors to be utilized, capillary type, orifice type, slot type, and dynamic feedback type. The general oil film stiffness model of different types of restrictors was constructed and the characteristics of different types of restrictors are analyzed and compared. The analysis results demonstrated that the stiffness of restrictors depend on the geometry and structure parameters, and according to the analysis results the all types of restrictors can be designed optimally.
