Ball Screws Critical Speed Thomson Linear

Every ball screw, or any shaft, has a rotational speed at which the vibration and harmonics becomes excessive. This speed often referred to as the screw critical speed and is a function of Exceeding the the critical speed of a screw may result in excessive vibration which can cause damage andor noise.

Difference Between Ball Screw Critical Speed And

Nov 11, 2019 Nov 11, 2019 The critical speed of a ball screw is the first order natural frequency of the screw shaft. As a screw shaft rotates, it begins to whip much like a jump rope. This behavior limits the screws critical speed. A screw shaft will naturally experience some bending, or sagging, due to its own weight. As the screw rotates, it tends to vibrate ...
