Der Maschinenbau (auch als Maschinenwesen bezeichnet) ist eine klassische Ingenieurwissenschaft und beschränkt sich längst nicht mehr auf den reinen Bau von Maschinen, Motoren, Getrieben, etc. C. of Friction = 0,08 to 0,16 The manufacturers of the proprietary keyless hub/shaft systems indicate that their products are based on a coefficient of friction of 0,12 for lightly oiled connections and 0,15 for dry assemblies. During the 1980s computer simulations began to support experimentalists by revealing dynamic effects in contacts.

The process leading to loss of material is known as "wear". Major types of wear include abrasion, friction (adhesion and cohesion), erosion, and corrosion. Wear can be minimized by modifying the surface properties of solids by one or more of "surface engineering" processes (also called surface finishing) or by use of lubricants (for frictional or adhesive wear) , source: Tribology of read online britwayz.org. Tribology is about effective lubrication and the analysis of such to achieve the desired result. Seizure is a failure of the concept of lubrication (by stoppage or excessive friction from lack of lubrication), in which tribology then becomes a failure analysis mode to determine the probable cause of seizure Tribology: Principles and Design Applications old.gorvestnik.ru.

This results in increased costs due to more frequent tool replacement, loss of tolerance as tool dimensions shift, and greater forces required to shape a piece. The use of lubricants which minimize direct surface contact reduces tool wear and power requirements.[ citation needed ] Edited by Haşim Pihtili, ISBN 978-953-51-1126-9, 252 pages, Publisher: InTech, Chapters published May 08, 2013 under CC BY 3.0 license The main goal in preparing this book was to publish contemporary concepts, new discoveries and innovative ideas in the field of surface engineering, predominantly for the technical applications, as well as in the field of production engineering and to stress some problems connected with the use of various surface processes in modern manufacturing of different purpose machine parts Proceeding of the Asme/stle Joint International Tribology Conference http://britwayz.org/?library/proceeding-of-the-asme-stle-joint-international-tribology-conference.

The effect of test device compliances and rigid body movement was minimized by measuring displacements very close to the contact interface. The measured displacements were successfully compared to the computed displacements of a corresponding finite element model , e.g. Alternative Fuels Emissions and Technology (S P (Society of Automotive Engineers)) Alternative Fuels Emissions and.

It has to be noted, that Stribeck’s extensive research [5] [6] on ball bearing steels identified the metallurgy of the commonly used 100Cr6H (AISI 52100).

Stribeck studied different bearing materials and aspect ratios D/L from 1:1 to 1:2 Basic Tribology http://old.gorvestnik.ru/library/basic-tribology. Tribology usually looks that the reduction of friction and wear. It covers modes of surface failures (e.g. wear, pitting, galling). It talks about material selection, coatings, lubrications, and processes to increase efficiency. Here is a "Cliff note" what I can remember from my college studies on this subject: - increasing contact surface area (e.g. line contact of roller bearings instead of point contact of ball bearings) to reduce pitting - softer materials flow better than harder ones, thus reducing friction - a great combination of hard and soft would be to coat a hardened material with a softer one Tribology Handbook, Third Edition http://old.gorvestnik.ru/library/tribology-handbook-third-edition. However, the higher sulfur content could interact with metal surfaces, because it was influenced by the increased temperature (higher sliding speed) and adsorption.
