In order to solve described problem, technical scheme provided by the utility model is：
A kind of ball-screw with anti-shaking device, including screw mandrel, buckle, commutator and nut, the ball-screw is also
Including anti-shaking device, the anti-shaking device includes left pedestal, Right socle, anti-shake ring and linear guide, the left pedestal, Right socle
It is the equal annulus of radius with anti-shake ring, the anti-shaking device inwall is provided with the anti-shake groove to matching with the nut, described
Left pedestal and Right socle are individually fixed in the both ends of the screw mandrel, and three pilot holes, the guiding are provided with the anti-shake ring
The center of circle in hole is located at same circumference, and the anti-shake ring passes through pilot hole and linear guide active link, the linear guide both ends
It is fixedly connected respectively with left pedestal and Right socle；The anti-shake groove agrees with the nut.
Optionally, the arc length between the pilot hole is equal.
Optionally, the left pedestal, Right socle, screw mandrel, guide ring are coaxially connected.
Optionally, the anti-shake groove is annular.
The beneficial effects of the utility model are：After anti-shaking device in the utility model is fixedly connected with screw mandrel, with
Leading screw is collectively forming a fixed space, so that it is determined that the movement locus of nut.When nut is transported on this desired trajectory
When dynamic, you can avoid and rock.
