Machine Design I. (Technical Drawing) Machine Design II. ?

• 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
