The aim of the course is to acquaint students with the principles and methods of machine construction and their basic tasks. Prepare to solve simpler structural calculations independently: to create structural models, to identify possible causes of failure, to estimate stress and limit states, to perform sizing and / or inspection procedures, especially with regard to various joints, mapping elements, shafts, rotors, couplings in machines , plain and rolling bearings, typical types of mechanical drives, gear-, worm-, belt-, chain- and friction drives.

In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, informed decision based on his analyzes. He is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
The theoretical curriculum of the subject is delivered by the four-hour lecture per week. The technical knowledge required for the successful completion of the partial and summary performance evaluations is described here. In the practical session, the emphasis is on practicing and deepening the curriculum of the lecture. The practical classes are of an educational nature and require the active participation of the student.

General rules
Learning outcomes are assessed on the basis of four mid-year written performance measures (two partial and two summative learning assessments). Summarizing academic performance evaluation: a complex, written way of evaluating the competence-type competence elements of the subject and knowledge in the form of a closed dissertation, the dissertation basically focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution to be resolved during performance evaluation. Partial performance assessment (homework): a complex way of evaluating the knowledge, ability, attitude, and autonomy and responsibility type competence elements of a subject, the form of which is an individually completed homework.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, simple | |
| Number: | 2 | |
| Purpose, description: | The aim of the task is to practice the application of tolerances and surface roughness, to use standard and selected parts from the product catalog. During the task, the cylinder components selected on the basis of the given data must be checked and the cylinder seals must be selected. Detailed technical documentation must be prepared for the task, which also includes exact technical drawings of the installation of the seals. | |
| Mid-term assessment No. 2 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | The aim of the task: to learn how to use the catalogs of different gears, to get acquainted with the different types of gears and couplings, to study the selection process of commercially available components. The task: select a complex, motor-driven gearbox from the catalog and a flexible or general compensating clutch for the output shaft! Detailed technical documentation must be prepared for the task. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 30 % |
| Mid-term assessment No. 2 | 70 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 86 % - 90 % |
| good (4) | Good [C] | 71 % - 86 % |

| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam not possible | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
