Course Description:
The course aims to introduce the most basic machine parts, giving insight to the engineering
speciality. The subject deals with machine parts and machine structures used in up-to-date machines,
their types, properties, and design principles. Main topics:
The concept of machine elements, groups, and design principles
− rotating machine parts, shaft joints,
− mechanical drives: gear drives, worm gearing, chain drive, belt drive. Principle of friction
transmission,
− brakes: structure, function, and design basics,
− supporting shafts, bearings, basic concepts of tribology
− storage elements: pipelines and fittings, pipe joints, valve, gate valve, check valve. Flow
losses of pipe networks, characteristic curves, reservoirs and seals,
− grouping of fluid machinery, characteristic parameters. Essential features of pumps, pump
head, efficiency, and useful power.
− structure of ventilation equipment and operation (fans, blowers, compressors, vacuum
pumps).

Competences:
− Knowledge of major environmental technologies, equipment and structures associated with each technology, including the functioning and operation thereof. − Adequate perseverance and endurance of monotony to perform practical operations. − Able to cooperate with engineers involved in the development and application of production and other technologies to develop the given technology in terms of environment protection. − Able to reveal deficiencies in the technologies applied and process risks and to initiate mitigation measures after getting familiarized with the technology concerned.
