Calculator Description
Shaft Calculator v1
The shaft calculator calculates the performance characteristics of a rotating shaft with four different bearing support options.

Shafts (critical speed)

Subject

The most common method for transmitting power from one place to another is via a rotating shaft, and apart from a properly designed lubrication system and correct bearing selection (see Bearings (low friction) and Bearings (plain)) the difference between a good shaft and a bad shaft is surprisingly little. It is therefore very important to understand what makes this difference and how to accurately define its most important characteristics.

For example; responsiveness and performance can be severely reduced if it is over-designed, and vibrations are responsible for power loss, excessive wear, noise, and early failure from fatigue all of which can be eliminated by ensuring that your shaft runs at the correct speed(s).

Calculator

Shafts calculates the performance characteristics of a rotating shaft identifying critical speed, natural frequency, amplification factor and stresses for four different end configurations.

The shafts calculator is a quick and simple calculation facility that may be used alone or in conjunction with our other related calculators; (Beams, Fatigue, Metals, Combined Stress, Bearings, Journals, Stress Concentration, Limits and Fits, Shock Loads, etc.) and its technical help should provide all the help you need to get the most out of it.

For help using this calculator see Technical Help
