  1. 1. On tribological design in gear tooth contacts

    Författare :Ellen Bergseth; Ulf Olofsson; Karsten Stahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; gear contact; gear manufacturing; surface boundary layers; surface topography; wear;

    Sammanfattning : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.

  3. 2. Gear Surface Machining for Noise Suppression

    Författare :Naser Amini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gear grinding; gear shaving; gears; undulation; surface topography; noise; automotive gearboxes; ghost harmonics; gear honing;

    Sammanfattning : Gear noise in modern automobiles is unacceptable. It has different sources, such as design parameters and manufacturing errors. Manufacturing errors, for example, can be reduced using advanced grinding operations. However, sometimes grinding operations can introduce micro-geometry deviations that cause severe noise problems.

  5. 4. Driving technology and development : Usability studies of gear shifters with variations in pattern, stability and design

    Författare :Sanna Lohilahti Bladfält; Jessica Körning-Ljungberg; Camilla Grane; Lisa Öman Ekervhén; Anna-Lisa Osvalder; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Usability; Gear shifter; Monostable; Polystable; Shift-by-wire; Engineering Psychology; Teknisk psykologi;

    Sammanfattning : Over the last few decades, the development of technology used in cars has moved forward at a very intensive pace. The focus has started to shift from the technology to the human as a user. LÄS MER

  7. 5. Towards a methodology for integrated design of mechatronic servo systems

    Författare :Fredrik Roos; Jan Wikander; Hans Johansson; Hendrik van Brussel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechatronics; Servo Systems; Design Methodology; Integrated Design; Construction engineering; Konstruktionsteknik;

    Sammanfattning : Traditional methods for mechatronics design are often based on a sequential approach, where the mechanical structure is designed first, and then fitted with off-the-shelf electric motors, drive electronics, gearheads and sensors. Finally a control system is designed and optimized for the already existing physical system. LÄS MER
