Ball Screw Critical Speed at Lola Wall blog

Ball Screw Critical Speed. Every ball screw, or any shaft, has a rotational speed at which the vibration and harmonics becomes excessive. The critical speed limit can be found by locating the point at which rpm (horizontal lines) intersects with the unsupported screw length (vertical lines) as modified by the type of. The critical speed of a ball screw is the first order natural frequency of the screw shaft. This behavior limits the screw’s critical speed. N c = f c ( d r / l c2) 10 7. The calculator uses the diameter, unsupported length and end fixity to determine the approximate rotational speed at which resonance will occur. Critical speed is essentially the rotational speed at which the ball screw will start to vibrate and introduce excessive oscillation (known as screw whip). It is recommended that the maximum rotational speed of a ball screw be limited to 80% of the critical speed. Critical speed ball screw and lead screws formulas and calculator: A screw shaft will naturally experience some bending, or sagging, due to its own weight. The critical speed is the lowest rational speed that a shaft is in resonance.
