Loaded Tooth Contact Analysis
Evaluation of loaded tooth contact and development of tooth modifications using commercially available software to improve and apply a realistic load distribution factor Km in gear rating calculations. Two real life gearing examples will be presented in the course, one will have a cantilever mounted pinion, the other a shaft pinion straddled non-symmetrically by bearings. Both examples demonstrate component deflections under load which significantly reduce tooth mesh contact which is then corrected with developed helix and profile modifications. Other gear performance optimization tools will also be presented, Material and Heat Treatment Selection, Profile Shift, Isotropic Finishing, Shot Peening, Accuracy. These design tools along with LTCA are commonly applied by gear designers to optimize design reliability and calculated rating safety factors.
This course is online. A webcam on your computer equipped with a microphone and speakers/headset are required for participation. Space is limited to 20-25 participants per course. Course materials will be mailed in hard copy. Please make sure to indicate your preferred mailing address in the registration process.
How Many CEUs Will I Earn?
As an IACET-accredited provider, AGMA offers 0.3 CEUs for this class.
- Identify the need for contact analysis and describe the theory behind the contact analysis process.
- Model the loaded gear mesh shafts, bearings and gear geometry in commercially available dedicated gearing “FEA” software to calculate magnitude and direction of tooth deflections and deformations.
- Develop tooth profile and helix modifications that compensate for tooth deflections, reducing transmission error and optimizing power density.
- Describe the tools and processes of contact analysis.
- Review cantilever pinion example of contact analysis and corrective action.
- Review non-symmetrical bearing mounted shaft pinion example of contact analysis and corrective action.
- Present contact analysis Do’s and Don’ts.
- Review other gear performance optimization tools.
Who Should Attend
Gear design engineers who are interested in developing state of the art competitive gear designs which provide optimized power density. Gear mesh loaded contact must be evaluated and improved using helix and profile modifications to achieve the assumed load distribution factor which has been applied in gear life and rating calculations. Loaded tooth, shaft and bearing deflections cause tooth mesh contact to shift, reduce in size and concentrate causing the potential for premature gear tooth fatigue failure. This course would be of interest to experienced gear manufacturing engineers, inspectors, quality assurance and operators to better understand the complex helix and profile modifications called out on high performance, optimized gear drawings.
