Course content
|
Application of essential methods from mechanics, elasticity and science of materials. Checking machine parts which are strained with static and dynamic loads. Connecting components based on the principle of a simple imbedded element (with keys, pins and the like), connections using friction (press fit connection, clamp connection), connections using some material (welded connections, brazed, soldered and gluet connections), connections with prestressed elements (with bolts, shrung-on rings). Transmitling parts (shafts, axes etc). Bearings (with concentrated or surface contact). Shaft couplings. Accumulators of mechnical energy (springs). Parts of piping´s systems. During seminars students practise machine design and perform calculate for the above mentioned machine parts. The lecture topics: 1. Machine parts and mechanisms - specialized design theory for machine parts. Static loading and loading of machine parts. 2. Dynamic loading and loading of machine parts (for fatigue). Joints utilizing the shape of load transfer elements - joints with pins, pins, grooving, polygons. 3. Friction joints for load transfer (I) - shrink joints 4. Friction joints for load transfer (II) - grip and spacer rings. 5. Joints using load-transfer material - joints by shape transitions, welds, solder and adhesives. 6. Joints using pre-stressed elements - joints with screws and clamps. 7. Rotary transmission parts - shafts, spindles, rotors, axes, pins, etc. 8. Rotary bearings with rolling contact - rolling bearings, lubrication and sealing. 9. Rotary bearings with flat contact - hydrodynamic, hydrostatic bearings, etc. 10. Accumulators of mechanical energy - springs rod, ring, disc, helical, leaf etc. 11. Shaft coupling - shaft couplings not disconnected, controlled and automatic 12. Transmission, connecting, compensating, closing, sealing, accumulators and other parts of piping systems. 13. Summary and conclusion.
