Basic constructions of machine design

Comparing the mechanisms of the up-to-date machinery with conventional ones, it is clear that both of them are built with the same standardized and well-known machine elements and are based on the same stressing and construction principles. A good example for this is the internal combustion engine and transmission of a modern motor vehicle which contains the same crank mechanism, gear drive, joints, bearing supports and sealing compared to the one, assembled 20-30 years ago. The object of this book is to introduce basic constructions and dimensioning considerations, with which the construction of any machine may be designed and a uniform engineering view may be developed. The first part sets forth the representation methods of machine parts. The second part introduces the stressing, sizing and construction methods proceeding of the four design tasks involved in the mechanical engineering BSc training at the University of Debrecen: Welded machinery base; Hydraulic cylinder; External shoe thruster released drum brake; and Counter drive. The objective of these design tasks is constructing the assembly drawings and shop drawings of the parts for manufacturing.
