Analysis of Hydrostatic Guideway Error Based on Multi-Head Pump

Abstract:

Base on the force balance theory, a model is set up to analyze the hydrostatic guideway with the closed four pads. Each oil pocket force is calculated, which is caused by the gravity center and the driving center of a slide carriage. According to the hydrostatic theory, the oil film variation that is generated during the movement is obtained. It is composed of linear and angle errors. The results show the driving force center and the geometrical center of the slide carriage have an effect on each oil film thickness, as well as the size and the location of the driving force. The article states their relationship and supplies the theoretical foundation for the design and employment of the hydrostatic guideway.
