![]() ![]() ![]() ![]() Here below are the input data and the corresponding image of the gear created clicking the "Run" button. Example 2 - Spur gear corrected tooth Consider to create the same gear of the Example 1 but with the number of teeth equal to Here below are the input data and the corresponding gear created with a 3D cad software using the downloaded DXF profile. Description Spur gears are the most common type of gears used in industry and they have straight, flat-topped teeth set parallel to the shaft. This web application creates an external spur gear by the simulation of the movement of the rack cutter and provides the following main tasks: calculate the geometric parameters of the gear, draw an accurate image of the gear with a detail of the teeth, adjust the tooth thickness by use of correction optimization of toothingcalculate the tooth root bending stress with the Lewis method, return a DXF file containing the 2D profile of the gear to be used with 2D and 3D CAD software. ![]() If there is no undercut, the software calculates the tooth root bending stress using the Lewis method, provides the geometric parameters of the gear and generates the DXF profile of the gear where the tooth profile is the true involute curve and the base radius is the true trochoid curve.įor the meaning of the terms used in the software and for additional information regarding spur gears, click on the "Spur Gears Help" button. Well done! You successfully create your spur gear! Data Input. ![]()
