A ball screw, like a lead screw, converts rotary motion into linear motion.
The device consists of a threaded shaft and a ball nut.
The latter device rides on the screw, supported by a series of ball bearings that provide a rolling surface rather than the sliding surface of a lead screw.
Advantages and Features
Roton’s rolled thread Ball Screws and high performance Ball Nuts replace the sliding friction of Acme, Hi – lead®, and Torqspline® lead screws with the rolling friction of ball bearings placed between the screw and nut members.
This construction results in very high mechanical efficiency and much less energy consumption for a given load.
Thus smaller motors and other drive components can be used with Ball Screws. The same torque applied to a conventional screw moving load “x” will move 3 times the load, “3x”, when applied to a Ball Screw.
Duty cycles can be more severe as less heat builds up in Ball Screw drive systems when compared to conventional screw drives. Predictable wear life and smooth, quiet operation are also obtained.
