1. Influence of Surface Carbon Content on the Wear of Threaded Connections in Rock Drilling Steels
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. LÄS MER
2. Performance Analysis of Environmentally Adaptable Grease in Large open gears
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. LÄS MER
3. Optimisation of tribology of Alfa Laval separator screw gear systems
Master-uppsats, Luleå tekniska universitet/MaskinelementSammanfattning : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. LÄS MER
4. Influence of ANS Triboconditioning on friction and fatigue in rolling contact configurations
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The automotive industry is constantly being challenged by customers and authorities to enhance the efficiency of the internal combustion engine (ICE) in order to achieve improved fuel consumption and reduced emissions. There are several interfaces within the design of an ICE that causes frictional losses, one of them is the valvetrain. LÄS MER
5. Tribological performance of different crankshaft bearings in conjunction with textured shaft surfaces
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Improving vehicle efficiency and complying to stricter exhaust emission legislations are some of the driving factors to advancement in technology of engine components. The main bearings in an internal combustion engine contribute significant amount of friction. These bearings support engine loads and allow free rotation of the crankshaft. LÄS MER
