Introduction to Gear Cutting & Measurement
Who should participate?
Engineers, technicians, supervisors, inspectors and setters who require an understanding and some practical experience in basic gear measurement and cutting. The course is designed for delegates who may have little or no prior knowledge of the subject but assumes that they are able to understand basic machine tool operations and trigonometry. (Please note that this course is limited to a maximum of 8 persons so early booking is recommended).
By the end of the programme participants will be able to:
- Understand basic spur and helical gear theory and terminology
- Carry out basic calculations for the manufacture and measurement of gears
- Understand how spur and helical gears are cut by hobbing and shaping
- Gain practical experience in setting up, producing and measuring gears made by hobbing & shaping
- Have a comprehensive set of notes and reference data
The programme will cover:
Basic involute gear theory, terms and definitions for spur and helical gears including:
- Gear terms and definitions
- Introduction to the involute form and its construction/tables
- Calculations on the above
Practical work on the measurement of gears including calculations on the following:
- Chordal tooth settings for gear tooth Vernier
- Constant chord settings to gear tooth Vernier
- Base tangent micrometer settings
- Distance over rollers measurement
Basic principles of gear hobbing and shaping.
Selection of index and feed change gears.
Practical work – setting up and producing spur & helical gears by hobbing and shaping using a Maxicut 2A shaping machine and Sykes H150 hobbing machine
