Selected chapters from machine design – mechanical drives (FSI-0KU)

Academic year 2023/2024
Supervisor: doc. Ing. Milan Omasta, Ph.D.  
Supervising institute: ÚK all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

Graduates will be able to analyze and design basic machine components used to transmit power and rotary motion, such as gears, shaft clutches, brakes and flywheels.
Learning outcomes and competences:
  • Knowledge of the principle and use of basic transmission mechanisms.
  • Ability to solve computational problems related to transmission mechanisms design.
  • Ability to apply the acquired knowledge in the design of new machines and devices.
Prerequisites:

Knowledge:

  • materials science (choice of materials),
  • statics (load analysis),
  • elasticity and strength (stress and strain analysis),
  • basics of design (creation of drawing documentation),
  • design of machine parts (bearings, joints).
Course contents:

The course extends and deepens skills especially in solving computational problems in the field of transmissions such as gears, belt, chain and rope drives, shaft couplings, brakes and flywheels. The course is a complement to the lecture, practice and home preparation of the course Machine design - mechanical drives (6KT).
Teaching methods and criteria:

Lecture.
Assesment methods and criteria linked to learning outcomes:

The course is classified with course-unit credit. The condition for obtaining it is more than 60% attendance at lectures.
Controlled participation in lessons:

Lectures: attendance at lectures is mandatory and controlled by the lecturer. In case of long-term absence, the replacement of missed classes is the responsibility of the course supervisor.
Type of course unit:
    Lecture  13 × 2 hrs. optionally
