MITCalc Internal Spur Gear: Engineering Calculation

Key Features

• Geometric design and strength check of internal spur gear with straight and helical toothing.
• Application is developed in MS Excel, is multi-language and supports Imperial and Metric units and solves the following main tasks:- Calculation of helical and straight toothing.- Automatic design of a transmission with the minimum number of input requirements.- Design for entered coefficients of safety (static, dynamic).- Calculation of complete geometric parameters (including corrected toothing).- Optimization of toothing by use of proper correction (balancing specific slips, miminizing specific slips, strength...).- Calculation of strength parameters, safety check.- Design of gearing for exact axis distance.- Complete calculation of tolerances in accordance with ISO 1328 (ANSI/AGMA 2015-1-A01)- Simple defining of the new materials according ISO 6336-5 (ANSI/AGMA 2001--D04)- Comprehensive theoretical part in the documentation.- Supplementary calculations (calculation of parameters of the existing gear, temperature rise, design of shafts,check dimensions).- Drawings of an accurate tooth shape including data (X,Y coordinates).- Support of 2D and 3D CAD systems.
• (AutoCAD, AutoCAD LT, IntelliCAD, Ashlar Graphite, TurboCAD, BricsCAD, ZWCAD, ProgeCAD, Autodesk Inventor, SolidWorks, SolidEdge, Creo).The calculations use procedures, algorithms and data from standards ANSI, ISO, DIN, BS and specialized literature.Used standards: ISO 6336-1:2006; ISO 6336-2:2006; ISO 6336-3:2006; ISO 6336-5:2006, ISO 1265; ISO 1328-1:1997; ISO 1328-2:1997; ISO 1122-1:1998, ANSI/AGMA 2001-D04 , AGMA 908-B89, ANSI/AGMA 2015- 1-A01, ANSI/AGMA 2015-2-A06This module is a standalone part of MITCalc - Mechanical and Technical Calculation Package for gear, belt and chain drives, springs, beam, shaft, bolt connection, shaft connection, tolerances and many others.
