    Abstract : The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. READ MORE

  6. 4. Simulation of contact, friction and wear in gears : a finite element approach

    University dissertation from Linköping : Linköpings universitet

    Author : Olle Lundvall; Linköpings universitet.; Linköpings universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gears; Gear noise; Contact mechanics; Simulation; Friction; Wear; Transmission error;

    Abstract : In this thesis, resent methods in computational contact mechanics is brought into the process of gear design. The finite element method is used to model two elastic bodies in contact. By defining a contact interface between these two bodies, constitutive laws, regarding normal contact, friction and wear, are included. READ MORE
