The Seminar will cover basic involute gear theory; terms and definitions for spur and helical gears. It will include an introduction to the involute form and its construction/tables; calculations on these; practical work on the measurement of gears including calculations on chordal tooth settings for gear tooth Vernier; constant chord settings to gear tooth Vernier; base tangent micrometer settings; distance over rollers measurement and basic principles of gear hobbing and shaping. Practical work will involve setting up and producing spur & helical gears by hobbing and shaping using a Maxicut 2A shaping machine and Sykes H150 hobbing machine.
