This software generates 3d models of gears aka Gleason spiral bevel, and aka Klingelnberg cyclo palloid. Download: sample gear, sample pinion tooth surfaces.  Accurate 3d models are used for advanced design and manufacturing.

This 3d modeling program has been developed for MS Excel file in order to make it easy to use. Input initial gear data such as diameter and number of teeth into Excel. The program will reccomend the remaining data to generate an igs surface file of the gear tooth. The igs tooth surface is good to use in any CAD/CAM for design, FEA or manufacturing.

This program has been sold in over 50 countries since 2010. Our customers report better results on torque capacity and reduced transmission error on CNC machined gears generated by our software in comparison to traditional gear cutting. The reason for better performance is ideal gear tooth geometry that our software delivers. The ideal tooth geometry is the shape of the gear tooth that delivers maximum torque capacity with minimum transmission error. In other words, the ideal gears transmit higher torque and run smoother at nominal position and with misaligned shafts. Traditionally, the ideal tooth geometry was approached by costly contact pattern development. Companies like Gleason and Klingelnberg offer tooth contact development software known as Gleason's GAGE or Klingelnberg's Kimos. The reason of expensive software is to simulate gear generating methods used on gear generating machines that these companies sale. These traditional gear generating machines are designed to naturally deliver an incorrect tooth contact a.k.a. non conjugated gear mesh. While Klingelnberg parallel tooth geometry is conjugated it has disadvantages of root undercut on the toe of pinions. On 90% of the gears machined by the generating method the ideal tooth contact is not possible even with special tooth contact development software. Modern gear generating machines have additional options in order to get close to the ideal tooth geometry. However, the ideal tooth geometry remains the goal for the very remote future when gears are cut by the generating method as we know it today.

The reason why we can comment on the gear generating method sold by Gleason and Klingelnberg is because we have software to accurately simulate their methods with high resolution in 3-d. Gleason and Klingelnberg machine summary are used by out other software for simulation of the resulting gear tooth form. With our own simulation software of Gleason/Klingelnberg machines, we have been able to validate the traditional gear generating method against our ideal method. Note, neither Gleason nor Klingelnebrg software provide deviations from the ideal conjugated tooth form while the option is easy to implement. They could provide a commonly used chart of deviations from the ideal on the left/right flanks as it is commonly done on spiral bevel gear inspection charts. Our program generates an ideal tooth form that can be used as a master to validate the output from Gleason/Klingelnberg software. In practice, the nominal tooth surface data file can be translated into a 3d CAD model using our Bevel+ Excel program to make it easy to visualize the differences of the tooth surface generated by Gleason/Klingelnberg and the ideal spiral bevel gear tooth produced by our program. It is always a good idea to use an alternative method to validate spiral bevel gear tooth geometry to reduce probable issues after transitioning into production.



Our program is based on the ideal conjugated spiral bevel design. It automatically delivers the ideal tooth geometry that has the largest area of the tooth contact for highest torque and minimum transmission error for smooth run. No need for the tooth contact pattern development because there is no more room left for improvement of our ideal tooth form.
