Abstract:
1. A compact surface self-compensated hydrostatic bearing system comprising: a rotor assembly including a rotor plate having an upper fluid restricting face and a lower fluid restricting face, and a rotor top and a rotor bottom having bearing surfaces angled with respect to an axis of rotation of the rotor assembly; a stator assembly including a stator top and a stator bottom attached to one another and housing at least a portion of the rotor assembly therebetween, the stator top having a bearing surface facing and spaced apart from the rotor top bearing surface forming upper bearing gaps therebetween; and the stator bottom having a bearing surface facing and spaced apart from the rotor bottom bearing surface forming lower bearing gaps therebetween, the stator top further including a lower fluid restricting surface facing and spaced apart from the rotor upper fluid restricting face forming upper restricting gaps therebetween, and the stator bottom further including an upper fluid restricting surface facing and spaced apart from the rotor lower fluid restricting face forming lower restricting gaps therebetween; and a fluid supply system configured to supply pressurized fluid to the upper and lower bearing gaps and into the upper and lower fluid restricting gaps.
