Content of teaching




Tolerances and fittings

Shaft-hub connections

Tutorials take place in concomitant to the lectures.


Lecture notes:

The Productdevelopment knowledge base PKB will be provided in digital form for registered students. All lecture notes and additional slides will be provided in Ilias.


regular attendance: 42 h

self-study: 80 h


The students are able to ...

  • evaluate different bearing arrangements according their particular application and characteristics and to describe system specific phenomena.
  • dimension a bearing arrangement and to chose, evaluate and dimension suitable bearings.
  • name and describe the function principals of different sealing's as well as evaluate and use special sealing's under consideration of particular boundary condition and choosing criteria's.
  • use the basic rules of designing on concrete problems. They understand the different designing stages and are able to name and take into account the requirements of designing.
  • to describe manufacturing processes and their caracteristics, as well as deriving and using the resulting boundary conditions of designing.
  • to understand the importance of the micro structure of a working surface for the required function. They have knowledge about surface measuring principals, can interpret measurement scribes and assign to a value to describe the surface. They can choose a process to manufacture the required surface and estimate their manufacturing costs.

The students know about the sense of standardization, their types and are able to classify and use standardization values in regard on product engineering.

They understand ...

  • different types of tolerances, the ISO tolerance system and are able to interpret different geometric tolerances.
  • the different effects of component connections and their dimensioning. They are able to choose and calculate a suitable connection and to illustrate their advantages and disadvantages.
Exam description

Concomitant to the lecture 2 online tests were carried out and the knowledge from the lecture will be tested. The knowledge from mechanical design I and II will further be controlled with a design and a CAD task.

Further information's will be announced at Ilias and at the beginning of the lecture mechanical design II.
