6. Rolling bearing lubrication at low temperature
Sammanfattning : Problems connected with rolling bearings at low temperatures are high starting and running friction, concerns about the presence of a lubricating film and the degree of roller slip at low-temperature start-up. Also, questions have been raised whether the high shear stresses in a grease sheared at low temperature could cause thickener degradation. LÄS MER
7. Synergies in Biolubrication
Sammanfattning : The objective of this thesis was to advance understanding in the field of biolubrication, finding inspiration from the human synovial joints. This was addressed by investigating the association of key biolubricants and the resulting lubrication performance. LÄS MER
8. Lubrication of conformal contacts with surface texturing
Sammanfattning : Conformal contacts like those found in journal or inclined slider bearings are widely encountered in various types of machines from small engines to large turbines. These contacts involve convergent gaps that are used to separate the surfaces in relative motion and generate pressure in the lubricant film. LÄS MER
9. Rough surface elastohydrodynamic lubrication and contact mechanics
Sammanfattning : In the field of tribology, there are numerous theoretical models that may be described mathematically in the form of integro-differential systems of equations. Some of these systems of equations are sufficiently well posed to allow for numerical solutions to be carried out resulting in accurate predictions. LÄS MER
10. Tribology of Rolling-Sliding Contacts under Mixed Lubrication : With focus on a Crankshaft Roller Bearing Application
Sammanfattning : A continuous increase in environmental legislation to reduce CO2 emissions is forcing engineers and scientists to develop more efficient and durable mechanical components, i.e. bearings, crankshafts, gears, etc. LÄS MER
