Abstract
A hydrostatic arrangement for a spin welding machine includes, a spindle rotationally supported with at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing, and a hydraulic unit configured to supply liquid to the at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing at at least two different pressures.
Claims21
A hydrostatic arrangement for a spin welding machine comprising:
- a spindle rotationally supported with at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing;
- and
- a hydraulic unit configured to supply liquid to the at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing at at least two different pressures.
A method of supporting a spindle in a spin welding machine, comprising:
- supporting the spindle with at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing;
- supplying liquid at a first pressure to the at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing when the spindle is rotating and the spin welding machine is not actively spin welding;
- and
- supplying liquid at a second pressure to the at least one of a thrust hydrostatic bearing and a journal hydrostatic bearing when the spindle is rotating and the spin welding machine is actively spin welding, the second pressure being greater than the first pressure.
