2. 1. Cam Roller Contact : Surfaces and Tribology

   Author : Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

   Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

4. 2. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction

   Author : Mohammad Shirzadegan; Daniele Dini; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Abstract : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. READ MORE

5. 3. Diesel Engnine Cam and Roller Follower Tribology

   Author : Martin Olsson; Maskinelement; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Cam; Roller follower; Mechanical engineering; Damage progress; Running in; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. READ MORE

6. 4. Elastohydrodynamic Lubrication of Cam and Roller Follower

   Author : Mohammad Shirzadegan; Jonas Ståhl; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : Modelling and simulation of friction is a research issue that still requires an extensive amount of input from the scientific community. In a lubricated system, the dissipation of energy is connected to the direct contact between the surfaces, or more precisely the tribofilms, as well as of the shearing of the lubricant film.

7. 5. Friction and wear in rolling and sliding contacts

   Author : Christer Spiegelberg; Sören Andersson; Roland Larsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; friction; wear; rolling and sliding contacts; Engineering mechanics; Teknisk mekanik;

   Abstract : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. READ MORE
