In the webinar, a 3DCS variation analysis software model will be used to validate the design and tolerancing of an individual gear. Standard tests and gear specification measurements are calculated using Monte Carlo simulation and predicted results are displayed including predicted deviation from nominal values and predicted range of values.
Multi-tooth contact with gear rotation enhances the 3DCS Gear Module to provide additional predictions. Virtual performance validation of gear assemblies includes the standard tests: Total Composite Deviation, and Single Pitch Deviation. Included are the 3DCS Gear Module measurements of Axial Backlash, Angle Backlash, and Pressure Angle. The location of the tooth-to-tooth in multi-tooth contacts corresponds to the Flank Test results.
The 3DCS Gear module was enhanced to simulate a Rolling Gear Gage to measure the Total Radial Composite Deviation. In the simulation model, the Master Gear Rotates, and the Work Gear is pressed against it, forcing contact at two locations, which will change as rotation occurs and new teeth come into the mesh.
The results are calculated from the measurement of the range of the distance between gear centers. In addition to this measurement, the angular deviation between teeth is also taken into account. These tests, leveraging the Digital Twin, provide savings by avoiding tooling changes and by optimizing the gear parameters, such as crowning.
