Abstract
PURPOSE: To achieve compactness, high accuracy and sealing, by coupling the rotary cylinder to the center shaft fixing one end to the fixing cylinder via the rotary sleeve freely rotatably, and by the construction that the upper end of the rotary sleeve is sealed, where lubricant oil of low viscosity is contained.
CONSTITUTION: The center fixed shaft 21 is supported to the lower housing 22. The upper cylinder cover 15 is tightened to the rotary sleeve 14 with the bolt 17 via the oil packing 16. The liquid bearing spacer 23 is inserted to the center fixing shaft 21 and spiral groove machining is made to the surface of the spacer 23. The pivot bearing 24 is provided at the upper end of the fixing shaft 21. Lubricant oil of low viscosity is filled between the liquid bearing spacer 23 and the rotary sleeve 14. Thus, compactness, high accuracy and sealing can be achieved.
