A CAD PACKAGE FOR THE DESIGN OF DIFFERENT TYPES OF GEARS

Abstract

Design of machine elements is a critical job, because these elements must be designed without any error according to their use. Also the design procedures differ from element to an other and they may need some iteration to find the final acceptable results, because in these procedures data may be collected from tables, figures, or graphs and used in some formulae and equations. For all of these difficulties this program is promoted. The program is to design three types of gears, spur, helical, and bevel gears according to the AGMA standards for the design of gears. Microsoft Visual Basic is the programming language used create this package for the design different types of gears. The required data for this program is the same as that data required for the manual design such as the bending strength, surface fatigue strength, gear ratio, power transmitted, angular speed, . . . etc. The benefits from this program are the time saving, ease of the design procedure, accurate results. Same input data for gears was calculated to compare between the manual design and computerized design (this CAD package). It was found the same The program was completed and tested. It was found to be correct and beneficial.
