2. Outline Project Description Objectives Project Alternatives Next Steps Concluding Remarks Questions

3. Project Description Sponsored by DynaTorque in Muskegon Design a quality control machine for their in- house hobbed gear assembly Use a combination of electrical and mechanical methods

4. Objectives Improve DynaTorque’s Current Quality Control Methods Automated Measurements –Tooth Alignment –Lead Angle –Center to Center Distance –Tooth Depth

5. Project Alternatives Tooth Alignment –Ball Bearing rides in groove –Measure extremes Center to Center Distance –Triangulate centers

6. Project Alternatives Continued Lead Angle –Measure distance between front and trailing edge of tooth –Drop in an arm to measure angle –Laser alignment Tooth Depth –Modify a Caliper –Use a probe

7. Next Steps Meet with DynaTorque again –Learn Current Measurement Process Finalize Design Material and Device Selection Finalize Poster Create a website

8. Concluding Remarks Design a Quality Control Device for DynaTorque Design must accept different gear sizes Use fundamentals of Machine Design Have Fun!!!
