Learning outcomes / competences:

The students are able to

• develop and design new technical systems by applying the methods of design systematics
• apply creativity methods in a meaningful combination,
• Define technical requirements and summarise them in a list of requirements as part of specifications and functional specifications
• Break down technical systems into solvable components using functional structures
• Select and present favourite solutions using evaluation methods
• differentiate between and design guide and transmission gears
• design and calculate spur and helical gears and gearboxes that can be derived from them, select gearboxes, couplings, belt and chain drives according to the application
• design a multi-stage gearbox and select a suitable electric drive
• analyse coupling gears, cam gears and simple planetary gears kinematically and carry out simple synthesis tasks

Contents:

• Straight and helical gears with involute toothing, gearing law, profile shifting, design, load capacity verification (tooth breakage, flank fatigue, scuffing), selection and use of gear drives, shiftable and non-shiftable couplings, belt and chain drives,
• Gear systems, basics of plane kinematics, force analysis of plane gears, synthesis of plane coupling gears (dimensional and positional synthesis), structure of cam gears, analysis of transmission and power ratios in planetary gears,
• Design of an electric drive.

The examination takes place in parallel to the lecture and tutorial as part of a project. Students are given a task with a specified time frame and a description of the work to be done. The project work is carried out in teams of several students according to the basic principles of project management. Individual performance is assessed by means of a presentation in which each student presents detailed solutions to the group work. In addition, project documentation, which also contains individual content, must be submitted at the end of the semester. However, the specific content is based on the respective task. Each student should submit at least one complete technical drawing of a component of the developed machine or new product.
