Claims

[Scope of utility model registration request]

A rotating shaft integrally formed with a thrust plate having a diameter smaller than the outer diameter of the rotating table is fixed to the lower surface of the rotating table, and multiple hydrostatic bearing pockets are provided in the circumferential direction on the inner peripheral surface of the shaft hole that fits into this rotating shaft. The formed pair of bearing metals are vertically spaced apart and installed on a table support, and a plurality of hydrostatic thrust bearing pockets are formed in the circumferential direction of the end surface of the upper bearing metal facing the lower surface of the thrust plate, and the upper bearing metal is A cylinder that fits into the piston flange protruding from the middle part of the rotating shaft is bored in the lower end surface of the metal, and pressure fluid is supplied to each of the hydrostatic bearing pocket and the hydrostatic thrust bearing pocket through a restriction. 1. A rotary table, comprising a pressure fluid supply means for supplying pressure fluid to the cylinder without passing through a throttle.
