1. 1. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces

   Författare :Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

   Sammanfattning : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. LÄS MER

3. 2. Running-in of gears - surface and efficiency transformation

   Författare :Mario Sosa; Ulf Olofsson; Stefan Björklund; Ulf Sellgren; Jorge Seabra; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; running-in; surface transformation; efficiency; gears; ground; superfinished; Machine Design; Maskinkonstruktion;

   Sammanfattning : With ever shorter development times and market demands on overall system performance such as efficiency, reliability and low maintenance, accurate predictive tools are necessary and gear drives prove to be no exception. All these characteristics have an impact on a process which has remained a riddle: running-in. LÄS MER
