Claims

[Scope of utility model registration request]

(1) In a ball screw in which a large number of balls are interposed between a ceramic screw shaft and a ceramic nut that holds a styrene-free circulator tube with a ball circulation function, the ceramic balls and A ball screw characterized in that balls made of a self-lubricating material are arranged alternately.

(2) The scope of the utility model registration claim, characterized in that the self-lubricating material used for the ball is a self-lubricating sintered alloy made by sintering molybdenum disulfide or tungsten disulfide with a metal binder ( 1) Ball screw described.

(3) As a self-lubricating material used for the ball, an intermediate layer coating is formed on the surface of the metal ball by ion blasting with a metal whose solubility is higher than that of the material metal of the ball or gold or silver. The ball screw according to claim (1) of the utility model registration, characterized in that a gold or silver surface coating is further formed on the surface of the layered coating by ion blasting.

(4) Claims for registration of a utility model, characterized in that the ball made of the self-lubricating material is a spacer ball.
1), <21 or the ball screw described in (3).
