Compared with conventional nut, ball runs along helical orbit direction, realizes circulating by reversing device.Add
The sound insulation at ball two ends and dustproof design, noise in operating reduces, and can prevent machining chips, abrasive particle, chemically reactive substance
Enter in spiral rolling track etc. micro- foul, reduce the abrasion of ball screw, extend the service life of ball screw, improve ball
The transmission efficiency of screw mandrel.
The beneficial effects of the utility model：
1st, a kind of nut for ball screw of the present utility model, ball runs along helical orbit direction, by anti-
Realize circulating in helical orbit to device.
2nd, a kind of nut for ball screw of the present utility model, its helical orbit bottom belt oil groove makes screw mandrel lubricate more
Fully, screw mandrel is more smooth with the transmission of nut by ball.
3rd, a kind of nut for ball screw of the present utility model, using sound insulation and dustproof design, noise in operating drops
Low, can prevent micro- foul such as machining chips, abrasive particle, chemically reactive substance from entering, reduce the abrasion of screw mandrel, extend ball
The service life of screw mandrel, improves the transmission efficiency of ball screw.
