Ball screw assembly introduction

Ball screw is a desired product which turns rotary motion into linear motion, or linear motion into rotary motion.

Ball screw systems consisting of a ball screw and a ball nut achieve linear motion with high precision and/or high speeds.  Efficiency is high at about 90% and ambient temperatures up to 110 degrees are possible.  Compared to mechanical belt driven systems they are more precise.  Compared to electric linear actuators they are faster and more precise. Compared to pneumatic and hydraulic systems they offer advantages of precision, controllability and efficiency.

Techdrives offer the Servomech range of ball screws that are manufactured on modern machine tools to exacting standards of precision.  

Its function is to turn the rotary motion into linear motion, which is a further extension and development of ball screw. The significance of this development is to move into a rolling bearing from sliding action. With little friction, ball screws are widely used in various industrial equipment and precision instruments.

How Ball screw work

The ball screw is an accurately machined threaded shaft with specific levels of precision and usually with customised shaft ends.

Ball nuts consist of a steel body, a quantity of balls, ball recirculation elements and wiper seals.

Rotation of the shaft causes the balls to roll in the ball screw threads and the matching threads inside the nut.  The rolling action achieves high efficiency linear motion.  The balls make a single, or several, revolutions inside the nut and then a recirculation element diverts the balls back to the start of their path.  DIN69051 defines standard nut dimensions although specials are possible 

Ball screw assembly International standards

ISO3408 and DIN 69051 define the screw accuracy and nominal dimensions for screw and nut.  As a general guide, the performance of systems manufactured with the same accuracy grades to these standards will be very similar. However individual components will not be interchangeable.
