• Gépelemek • Gépszerkezetek • • • Machine parts ~ components ~ elements • • ~ design ~ details • ~ structures • Engineering Design
aim • to introduce the structure of machines, the function, type and load of machine elements and the main methods of designing them • Main chapters of this semester: – Fits & tolerances – Basics of stressing – Joints – Drive systems 1.
Connecting subjects machine design I and III mechanics I, II, III engineering materials ….
pneumatics and hydraulics
