  1. 1. Gear Tribology - Friction and Surface Topography

    University dissertation from Chalmers University of Technology

    Author : Li Xiao; Högskolan i Halmstad.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Friction; Surface topography; Toughness; Lay; Gears; Power transmission; Teknisk mekanik; Engineering mechanics; friction; surface topography; toughness; lay; gears; wfficiency; power transmission;

    Abstract : The quest for energy efficiency leads to the development of highly efficient power transmissions for vehicles. Gears are some of the most rugged and durable torque transmitters among machine elements. Friction between sliding surfaces at gear teeth is one major source of power loss. READ MORE

  3. 3. On the running-in of gears

    University dissertation from Stockholm : KTH

    Author : Sören Sjöberg; KTH.; [2010]
    Keywords : gears; gear manufacturing; running-in; surface topography; contact area ratio; manganese phosphate; TECHNOLOGY Other technology Mechanical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Maskinteknik;

    Abstract : The general trend in gear industry, today, is an increased focus on gear transmission efficiency. Gear transmission efficiency losses arise from loaded and unloaded gear contacts, seals, lubricant and bearings. One way of minimising the losses is to lower the lubricant viscosity. This will reduce the speed dependent losses. READ MORE

  4. 4. Surface Integrity Characterization of Gears with respect to Running-in

    University dissertation from Chalmers University of Technology

    Author : Dinesh Mallipeddi; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gears; running-in; micropitting; surface roughness; residual stresses; surface chemistry; surface asperities;

    Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. READ MORE

  5. 5. An approach for systematic process planning of gear transmission parts

    University dissertation from Stockholm : KTH

    Author : Mats Bagge; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process planning; machining; gears; beredning; bearbetning; kugg; TECHNOLOGY Industrial engineering and economy Manufacturing engineering and work sciences Manufacturing engineering; TEKNIKVETENSKAP Industriell teknik och ekonomi Produktion och arbetsvetenskap Produktionsteknik;

    Abstract : The objective of this thesis is to find and develop methods that enhance and support the creation of evolvable master process plans with possibilities to challenge productivity and meet changing design requirements. The condition for achieving this is primarily that both the fundamental thinking and the results behind a process plan can be described. READ MORE
