Abstract

PURPOSE: To realize high precision and compactness by building a fluid lubricating bearing and thrust bearing in a fixed sleeve and turning axis.
CONSTITUTION: In fixed sleeve 21 incorporated in one with lower housing 7 and having opening part 30, turning axis 3 is locked being rotatable and while radial fluid bearing 22 is provided between fixed sleeve 21 and turning axis 3, thrust bearing part 23 is also provided on the opposite surface to lower housing cover 25 of turning axis 3. Consequently, turning axis 3 turns without touching mechanically the inside of fixed sleeve 21 and when it is eccentric, it is returned to a balancing state by the wedge effect of a sealed-in lubricating film, displaying a turning function with high precision while compacting the assembly in comparison with the use of a ball bearing because of the use of radial fluid bearing part 22.
