Claims

[Scope of utility model registration request]

In a turntable that levitates and rotates a rotary table via an air bearing in order to mount and rotate a large device, a plurality of air bearings are installed on the bottom of the rotary table as a levitation system for the rotary table. It is removably attached to the top of the table and fixed at an appropriate location, and is connected via an air hose to a rotary joint provided at the center of the bottom surface of the rotating table, and the rotary joint is connected via a pit provided at the corresponding location on the floor of the base. As a drive system for the rotary table, a roller chain is rotatably fixed around the rotary table and meshed with a sprocket driven by an air motor, and the roller chain is connected to the guide outer periphery of the rotary table. Fix multiple guide rollers to the base floor surface at appropriate points,
The sprocket and air motor are attached to a drive frame fixed to the base floor surface via a linear bearing so as to be slidable up and down and in the direction of the rotating table, and an air cylinder is provided on the drive frame so as to be movable in the direction of the rotating table. A turntable for mounting large equipment, characterized in that it is configured by being connected to.
