Abstract
PURPOSE: To compact this device and to produce this device that its accuracy is high, by each mounting a first bearing between a rotary sleeve and a central fixed shaft and a rotary means of the rotary sleeve between the first and second bearing portions of the rotary sleeve.
CONSTITUTION: A metal bearing 16, a first bearing portion, is pressed into a rotary sleeve 14, and held between the sleeve 14 and a central fixed shaft 17 when the rotary sleeve 14 is fitted to the central fixed shaft 17 in a revolution-possible shape. An inner ring of a radial ball bearing 18 forming a second bearing portion is fixed to the rotary sleeve 14 by means of a thrust retaining ring 19 and a fixed ring 22, and pre-pressure in the thrust direction of the radial ball bearing 18 can be changed according to the clamping conditions of a screw of the thrust retaining ring 19. Thus, a space between both bearings 16, 18 can be made larger than conventional devices because the metal bearing 16 is installed to a portion corresponding to an inwall of an upper cylinder, type tension is received by means of the metal bearing 16 and open-side support can be eliminated.
