定义
A critical component in linear motion systems that mates with the screw shaft to translate rotational movement into precise linear displacement. Ball screw nuts contain recirculating ball bearings for low friction, while lead screw nuts use sliding contact or polymer inserts.
工作原理
Operates through mechanical engagement with the screw's helical grooves. In ball screw nuts, balls recirculate through raceways to minimize friction. In lead screw nuts, material deformation or sliding contact provides the driving force with inherent damping.
材料
Typically alloy steel (SCM415SCM440)stainless steel (SUS304SUS440C)or bronze (CAC502). Polymer inserts may use PTFEPOMor nylon composites for lead screw applications.
Thread Type
Metric, ACME, or custom
Preload Type
Double nut, offset preload, or single nut with spacer
Accuracy Grade
C3-C10 per ISO 3408
Mounting Configuration
Flanged, cylindrical, or square
Lubrication Requirement
Grease or oil bath
标准
ISO 3408DIN 69051JIS B1192

常见问题

What is the difference between ball screw nuts and lead screw nuts?

Ball screw nuts use recirculating ball bearings for high efficiency and speed, while lead screw nuts rely on sliding contact or polymer inserts for self-lubrication, damping, and cost-effectiveness in lower duty applications.

How do I select the right nut preload type?

Choose double nut for adjustable preload and backlash elimination, offset preload for compact designs, or single nut with spacer for standard applications. Consider required stiffness, backlash tolerance, and assembly constraints.
