Designing of belt-pulley mechanism by aid of comfuter

In this study, a program was prepared to design of Straight belt, Narrow V belt, Normal V and Triger belt by using directions and determined inputs of user, which is manifactured according to TSE and DIN standarts. The paremetric design of the belt-pulley mechanism has been made by VBA(Visual Basic for Application) in AutoCAD programme. Type of the belt can be selected on a list which is added to VBA depend on input cycle and power conveyable of the belt. The sizes which were taken from standard belt-pulley lists have been added to VBA by creating sub-programmes in Modules. The selected belt type and pulley can be drawn 3D and 2D in AutoCad with the taken sizes from the mentioned sub-programmes above. For the Narrow and Normal V belts, the conveyable power has been placed to Microsoft Excel Sheet. For the Narrow and Normal V belts, the conveyable power has been placed to Microsoft Excel Sheet. The minimum diameter of the pulleys which have been selected according to the belt types have been increased and searched various designings. Then All these studying have been performed for users. It is prepared in a structure which convertible structure serves designs and educational actions.
