GearCAD functions as a complete gear design tool, presenting a comprehensive set of calculations associated with geometry of involute gears and design of internal, external and planetary gear sets.
GearCAD pays off by saving time, relieving the designer of the tedious chores associated with complicated gear calculating formulas. Using GearCAD, the gear design becomes a few steps task. Long-short addendum, non standard center distance, selectable backlash, tooth sizing, load checking, are some of the many capabilities of the program.
GearCAD will calculate for you all the dimensions and parameters necessary to design, manufacture and measure gears to the proportions of selected Tooth Form System.

• Easy-to-use Visual Gear and Spline design. No need for knowledge of complicated gear formulas. Instantly computed results. Runs on personal computers and compatibles (386, 486, Pentium or better)
• Works on MS Windows 98 SE, NT, 2000, XP ( 32 bit OS only )
  GearCAD will work on Windows Vista Business or Windows 7 Pro with Virtual XP Mode installed. (32 bit OS only)
  Note:
  To run GearCAD on Widows 7 Virtual XP
   • Install GearCAD on the Virtual XP, then select Disable Integration Features from the Menu.
   • Double-click the GearCAD icon on the Desktop to run GearCAD
   • If required, reduce the WIndows 7 Screen Resolution - this will enlarge the GearCAD's display.
• Calculates span measurement over teeth and measurement over wires.
• Calculates contact diameters, start of involute profile, undercut diameters, checks for interference undercut and "trimming" on internal gear sets, balanced specific sliding ratio, efficiency of gear train.
• Calculates "I" and "J" AGMA Factors.
• Graphically displays tooth profile in mesh for visual analysis.
• Automated planetary design procedure.
• Highly Accurate DXF Gear Profiles:
  • DXF File output for wire cutting and CAD/CAM/EDM. The designed gear set can be imported into most CAD programs (AUTOCAD, CADKEY, etc.) for further processing.
  • The generated DXF gear profile output is highly accurate, with user selectable precision - as if generated by a physical cutting tool - not an approximation - which is a common complaint about some of our competitors!
• Cutter selection and Outside Diameter Truncation inputs.
• Fractional number of teeth input - for special designs.
• Base Pitch Tables to find Pressure Angle, Module or DP of a broken, worn or unknown gear. Includes a comprehensive printed Users Guide - with design examples.
