Therefore, the use of this kind of gear drawing software allows large scale improvement in gear designs. Without this kind of dedicated gear drawing software, it would be necessary, after gear sizes have been determined, to use conventional CAD software and draw the gears from scratch. It also allows downloading the produced original (custom) gear drawings in the dxf format and expands them by using CAD software. The gear drawing software means an on-line automatic program to produce gear drawings when users input various parameters needed to define gear sizes. This gear calculator software also handles gear calculations of various types of gears such as spur gears, worm gears, gear racks, bevel gears, internal gears, screw gears, etc. Among the parameters requiring user input are the unit to specify gear tooth such as module or diametral pitch (DP) and its value, pressure angle, helix angle, number of teeth, coefficient of profile shift, center distance, material, rpm (rotational speed), face width, safety ratio, circumferential backlash, etc. By utilizing the gear calculator introduced here, it is possible to reduce these burdens substantially. Because gear calculations require many complex formulas related to strengths and sizes, traditional gear design situations require highly specialized knowledge and suitable design time.
The gear calculator is a comprehensive software which, after inputting various parameters related to gear calculations, computes on-line automatically gear sizes, strengths, working forces, tooth forms, backlash conversions, etc.
