Gear Engineering

---

Description:

Gear fundamentals; Materials: steels, localized hardening of teeth, cast irons, nonferrous and nonmetallic; Force analysis and bearing loads: spur, helical and worm; Design: Fundamental design includes Lewis beam strength, Buckingham's dynamic load and wear load, corrections, characteristics and distribution, scoring, thermal limits, indexes of tooth loading, data needed for drawing and rating practice; Gear box design: ray diagram, and kinematic layout. Manufacturing: hobbing, shaping, milling, broaching and punching, casting, injection molding, sintering, cold drawn and rolled worm threads; Finishing: grinding, shaving, rolling, honing; Failures: system, tooth, bearing and lubrication failures; Metrology: functional checking, equipments, tooth thickness, single flank and backlash. Few research aspects include asymmetric and micro gears.
