The goal of the course is to introduce the students to the design of specific parts and assemblies of the high speed machines.

Upon successful completion of this course, students should be able to deal with the engineering design of specific parts and assemblies for high speed machine systems. The design methodology implies teaching student to calculate and correctly select bearings, couplings, seals, gears and other machine elements for operation at high speed revolutions. In addition students will have basic knowledge in the field of the design of housing, lubrication, balancing and testing of such systems.

• Bearings : types, characteristics, operating temperature, misalignment compensation, rotation speed, axial/radial forces, bearing selection, lubrication, sealing, cage types, low friction, fixed/loose/floating bearing principle, bearing mounting, bearing life assessment. • Seals: sealing principle, types, materials, non-contact seals. • Couplings: types, advantages/disadvantages, misalignment compensation methods, rotation speed, shaft connections, gear joints, clamping devices, key connection, flange connection. • Shafts: dimensioning, rotor dynamics, balancing. • Finite element method: basics, structural calculations, modal analysis. • Testing and mounting of high speed machine systems. • Испитивање и склапање високо обртних система. • Software : ANSYS, KISSsoft.

Presentation of machine elements that are suitable for high speed opetaion. Visiting facilities for engineeritn design, production and testing,of high speed machines.
