| 摘要 |
The invention relates to machine-building and can be used for compensation of machine spindle displacement depending on loads coming to existence at processing nonbalanced workpieces in hydrostatic bearing (GSB). Controller of rigidity of hydrostatic bearing has a body in which pilot spool is placed, this controls vibrations of spindle through change of pressure of working liquid and channels for supply and discharge of liquid to pockets of hydrostatic bearing. Controller is additionally equipped with three pilot spools, at that all the spools are placed in the body in radial positions at angle of 90 DEGREE one relative to another, and in the opening of the body for the spindle placement elastic ring is placed, this at the side of contact surface with spindle has polycrystalline super-hard coating, and at the other side it can contact with spools. Automation of the process of compensation of liquid flow rate in pockets of GSB is provided, due to presence of control of resilient displacements of the spindle.
