Abstract

PURPOSE:To ensure the stable support of a disk laminated body, by providing a movable shaft having an opening to blow out the air at the inner part of each flexible disk of the disk laminated body and a driving means which gives a parallel movement to the movable shaft so that said opening moves in parallel and along the position of a space formed between the flexible disks. CONSTITUTION:A disk laminated body 1 is continuously driven at a certain speed by the revolving force of a motor which is transmitted via a pulley 10 and a driving belt 9. The compressed air within a hollow space of the body 1 flows between the disks 18 and in the radius direction of the disk by the function of the centrifugal force. The compressed air set at a prescribed level is supplied into the space 11 in order to keep the space stably between the disks 18. The air is led from a low pressure air source to the spaces 11 formed at both sides of a nozzle constituting body 29 through an air pipe 27 and an air path 26 of a collar 25 and then discharged through the space between the disks 18. At the same time, the air having the same pressure as that in the space 11 is led into a vacuum chamber 39 near the body 29 in order to secure the stable revolution of each disk 18.
