Spiral Bevel Company - SPIRAL BEVEL GEAR Software Spiral Bevel gear software is now available. Download Spiral Bevel software user guide in PDF (8Mb) Because of the complicity of the tooth geometry, better spiral bevel software has been always very critical for manufacturing. Spiral Bevel Co has adopted Direct Digital Simulation (DDS) method, as an underlying mathematical algorithm for writing of software. DDS method has shown advantages compare to the traditional differential geometry method. The key advantages of the DDS modeling method versus traditional method are: reduced cost of calculation, ability to calculate complex tooth geometry, higher accuracy of tooth geometry calculation, higher accuracy of tooth contact simulation, and higher resolution of visualization.

Design software.

Because our Spiral Bevel software provides accurate geometry of the tooth root we can accurately use Finite Element Method (FEM, FEA) for calculation of the root stress. Calculation of the root stress is critical for prediction of the fatigue of the gear tooth on bending.
Spiral Bevel software allows better optimizing all the parameters of the spiral bevel gears.

Manufacturing software.

The first version of our manufacturing software has been developed and used in production of spiral bevel gears in 1986 for automotive, aerospace, marine and for other applications. In 1986 we developed the software for simulation of common Gleason and Klingelnberg gear manufacturing methods. Originally our software would calculate the tooth geometry from the machine summary in order to predict the finished geometry of the gear tooth. The reason for the original development of our software was a to develop a mathematical model of the tooth that allows more accurate gear manufacturing compare to the mathematical tools used by Gleason or by Klingelnberg.

Tooth Contact Analysis (TCA).

TCA is critical in manufacturing of gears. We have developed more accurate mathematical tool for calculation and visualization of the tooth contact.

TCA software from Spiral Bevel Co calculates the tooth contact area, the immediate and combined contact pattern, the contact pass, sliding velocities, rolling velocities, and all the mentioned data in animation while gears rotate in mesh. Calculation of the loaded contact pattern is conducted with help of FEA software. The software accounts for the bending deformation of the tooth and for the compression of the tooth surface.

Our software is capable to reproduce the exact 3-dimensional tooth geometry existing gears. If the summary is not available, the software can reproduce the original Gleason or Klingelnberg summary from the CMM inspection data.
In practice, our software helps us to reverse engineers and manufacture gears and pinions so we can supply replacement parts.
