2. 1. On tribological design in gear tooth contacts

   Author : Ellen Bergseth; Ulf Olofsson; Karsten Stahl; KTH; []
   Keywords : 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;

   Abstract : 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.

4. 2. Influence of running-in on gear efficiency

   Author : Sören Sjöberg; Ulf Olofsson; Björklund Stefan; Lehtovaara Arto; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; gear manufacturing; running-in; efficiency; friction; surface topography; Machine Design; Maskinkonstruktion;

   Abstract : The general trend in gear industry is an increased focus on gear transmission efficiency. This thesis focuses on the understanding of how different gear manufacturing methods – particularly the contribution of the running-in process – affect the surface characteristics and friction response, with the purpose of increasing gearbox efficiency.

5. 3. On the running-in of gears

   Author : Sören Sjöberg; Ulf Olofsson; Anders Flodin; KTH; []
   Keywords : gears; gear manufacturing; running-in; surface topography; contact area ratio; manganese phosphate; Mechanical engineering; 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

6. 4. Gear Surface Machining for Noise Suppression

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

   Abstract : 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.

7. 5. Process planning for precision manufacturing : An approach based on methodological studies

   Author : Mats Bagge; Bengt Lindberg; Anders Kinnander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; precision manufacturing; machining; tolerance chain analysis; process behaviour; process performance; process capability; in-process workpiece.; Production Engineering; Industriell produktion;

   Abstract : Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task.
