摘要：Gears as power transmission devices are capable of changing the speed, torque, and direction of a power source and are considered to be one of the most important devices used in many types of machinery owing to their durability and higher power transmission efficiency. Worm gears as a type of gear are widely used for transmitting power at high velocity ratios between non-intersecting shafts. Worm gears are very useful in machine design but its design requires a lot of design assumptions and calculations. To achieve a rapid design devoid of errors, there is need to have a customized computer program capable of designing worm gears using standardized design equations; and that is what WormCAD stands for. The software was designed using JavaScript programming language and the Node.js platform. The WormCAD was tested to be accurate, faster and convenient hence it will be a viable software to be used by worm gear designers.
