Hertzian contact theory - About Tribology

29/10/2017· Hertzian contact stress. Hertzian contact theory is a classical theory of contact mechanics and is a very useful tool for engineers and researchers. Even though the derivation of the theory is relatively difficult, the final solution is a set of simple analytical equations relating the properties of the system to the developed stress.

Understanding lubriion from the bearing’s perspective - …

10/6/2019· Understanding friction. The main purpose of lubriion in bearings is to separate metal surfaces, support loads, and eliminate or minimize wear. By developing a layer of oil between the rollers and raceways, oil actually can separate the moving components, fully supporting the bearing loads and preventing wear.

Ball screw preload: What you need to know - Linear Motion Tips

11/5/2018· Ball screw preload: What you need to know. When a linear motion appliion requires high thrust force and rigidity along with good positioning accuracy, a preloaded ball screw assely is often the best choice. Manufacturers offer ball screw preload amounts ranging from just 1 or 2 percent for appliions where backlash would be detrimental

The Three Mistakes of Bearing Lubriion - Appliions - …

19/5/2016· Mistake 2 – Over and under Lubriion. The second mistake we must avoid is adding too much, or not enough grease. Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease.
