Abstract
In this paper, the result of the research of threedimensional (3D) geometric parameter modelling of the two frequently used types of mechanical transmissions, belt transmissions (belt pulley with cylindrical external surface, or more exactly, with pulley rim) and transmissions gear (bevel gears) using CATIA V5 software system, is shown. Parameter modelling application makes possible the control of created geometry of 3D model through parameters integrated in some relations (formulas, parameter rules and so on). All dimensions, or more exactly, geometric changeable parameter of belt pulley and gear, can be expressed through few characteristic fixed parameters. Geometry of 3D mechanical transmission model is changed by changes of these parameters values. Designer could generate more designing solutions by mechanical transmission parameterisation. Final taking into consideration shows that components parameterisation must obligatory apply in interaction with previous traditional geometric modelling approach.
