Abstract
Abstract



The Lame equation and finite element analyzing program, "ANSYS" for the designing of the hydraulically pressed couplings are applied to calculate and analyze their axial, torsion and bending loads. These are considered as mechanical and geometrical particularities of hydraulically pressed coupling properties to improve their technical performances. The finite element analyzing program "ANSYS" is used to confirm local structural properties instead of Lame equations. The correlations for geometrical and mechanical properties are estimated for sleeve and flange types of hydraulically pressed couplings under consideration. The correlations for hydraulic and metal properties of the hydraulically pressed coupling are defined for dimensional range from shaft diameter 100 mm to 300 mm. The factors for considering of hydraulically pressed coupling properties are classified into three groups : the first is focused on to define designing, machining and assembling of the outer and inner sleeve, the second is focused on the defining of hydraulically pressed joints of the interference fit and the third is focused on specific contact pressure on the conjugated surfaces and axis pressing forces for driving up outer sleeve of the coupling. The simplified static test procedures of hydraulically pressed coupling is suggested for the quality assurance of the classification society to get the type approval. There are some suggested modifications to improve properties of hydraulically pressed coupling which includes an eccentric insert in the shaft connections to reduce coupling diameter. The large outer sleeve with short sleeve length is used to reduce stress concentrations for marine large diameter shafts(larger than 1,000 mm) and the oil detergent of sleeve inside is used to increase transferring torque. Moreover, the advanced structural design method presented in the thesis would be a successful standard paradigm for designing a high quality hydraulically pressed couplings.
