摘要: A ball crew unit with dual ball deflect arrangements includes a pair of circulation ball deflect units. One of then is equipped axially in a first cavity provided in the nut, while the other is equipped radially in a second cavity provided in the nut. By so, the traditional buck toothed design for the male screw threads of the bolt can be eliminated, and is unnecessary to lengthen the nut in order to avoid mutual interference between the ball deflect unit and the nut flange, the circulation tunnel formed in the nut does not have to run through the whole nut either so that the structure of the ball screw unit can be simplified. As a result the assembly work is facilitated, production cost is reduced while the mechanical property is upgraded.

摘要: A ball screw assembly, wherein a helical groove is formed in the outer surface of the screw shaft without extending to both ends thereof, and an escape portion formed in the form of a slot is connected to one end of the helical groove of the screw shaft. The escape portion allows the cassette to abut against an outer periphery of the screw shaft, and the tongue portion is inserted deeply in the escape portion, such that the cassette is allowed to be rotated to effect axial movement relative to the screw shaft, thus finishing assembly of the nut, and the balls can be prevented from dropping out of the ball screw when the nut is disengaged from the screw shaft or when the nut moves out of travel.
