A ball screw, while the setting of water pipe can effectively reduce the noise generated when screw rod work, more hommization.
To achieve the goals above, the utility model is to realize by the following technical solutions：A kind of outer circulation type rolling
Pearl screw rod, including screw body, nut and fixed ring, the screw body are equipped with rolling groove, ball are equipped in the nut,
The nut is fitted to by ball and rolling groove on screw body, and the nut side is equipped with screw thread, the fixation
Avris is equipped with thread groove in ring, and the fixed ring is fitted on nut by screw thread and thread groove, is set on the nut
There are ball circulation passages, ball circulation passages one end setting is in nut top, the ball circulation passages other end setting
Water pipe is arranged on nut bottom, the ball circulation passages, the nut side is exported equipped with ball.
As a kind of preferred embodiment of the utility model, ball groove, the ball setting are equipped in the nut
In ball groove, the ball outlet is connected to ball groove.
As a kind of preferred embodiment of the utility model, the recess radian of the rolling groove is opposite with ball radian
It answers.
As a kind of preferred embodiment of the utility model, the specification of the screw thread and thread groove is corresponding.
The beneficial effects of the utility model：A kind of external circulation type ball bolt of the utility model, including screw body, spiral shell
Mother, fixed ring, ball circulation passages, water pipe, rolling groove, screw thread, thread groove, ball, ball outlet.
1. the fixed ring of the external circulation type ball bolt nut side can be removed, since nut side goes out equipped with ball
Mouthful, ball can be taken out after fixed ring is removed, ball is only needed to change when ball is worn, nothing needs to change whole
Screw rod.
2. the external circulation type ball bolt ball circulation passages are equipped with water pipe, are eliminated into Row noise using water, effectively dropped
Low noise pollution, more hommization.
3. the external circulation type ball bolt is reasonable for structure, ball can take out replacement, without directly replacing entire ball spiral shell
Bar, while the setting of water pipe can effectively reduce the noise generated when screw rod work, more hommization.
