BALLSCREW MECHANISM Russian patent published in 2007 - IPC F16H25/20 

FIELD: the invention refers to instrument making namely to mechanisms for transformation rotary motion into advance motion and vice versa.

SUBSTANCE: the mechanism has a screw 1 interacting with a separator. The separator is formed with axles 7 on which small balls 2 and 3 take turns. The small balls interact as with the grooves of the profile of the screw so with its combs. Springs 5 are installed on the axles 7 taking gap at transmission of the rotational moment in the arrangement. The axles themselves are hardened from the two sides on advance moving flanges 4.

EFFECT: achieves high sensitiveness of the motion of the mechanism.
