   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Andreas Hälsing; [2023]
   Keywords : carbon content; wear performance; carburized steel; dry contact interface; threaded connections; drill rods; samples; shot peening; production process; twin-disc wear tester; RPM; operating conditions; wear rate; surface topography; hardness; optical analysis; light optical microscopy; scanning electron microscopy; surface carbon content; microstructural changes; frictional heat; contact pressure; wear mechanisms; plastic deformation; adhesive scratching; material removal; delamination;

   Abstract : 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. READ MORE

3. 2. Performance Analysis of Environmentally Adaptable Grease in Large open gears

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Victor Ogunmoye; [2022]
   Keywords : Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

   Abstract : 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. READ MORE

4. 3. Optimisation of tribology of Alfa Laval separator screw gear systems

   University essay from Luleå tekniska universitet/Maskinelement

   Author : Anurag Singh; [2022]
   Keywords : Screw gears; Tribology; Wear; Lubrication; Materials; Surface; Roughness; Twin disc tribometer;

   Abstract : 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. READ MORE

5. 4. Influence of ANS Triboconditioning on friction and fatigue in rolling contact configurations

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Björn Hedmark; Per Wallgren; [2019]
   Keywords : Tribology; friction; fatigue; micropitting; surface engineering; twin-disc; triboconditioning; LTU;

   Abstract : 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. READ MORE

6. 5. Tribological performance of different crankshaft bearings in conjunction with textured shaft surfaces

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Lakshminarayana Reddy Tamatam; [2017]
   Keywords : Tribology; journal bearings; engine main bearings; automotive; friction; wear;

   Abstract : 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. READ MORE
