You are required to determine gear parameters of one set of gears.
The number of teeth on the pinion and gear is specified for each student on the next page.
Standard Gear Requirements:
Module m 15.0000 mm
20.0000 degree pressure angle
addendum 1.0 module (i.e. 15.0000 mm)
dedendum 1.25 module (i.e. 18.7500 mm) tooth thickness = (tooth space - 0.5000 mm) measured on pitch circle
For a standard gear set you should calculate the following information for the pinion AND gear in mesh. Assume that the pinion is rotating in a clockwise direction.
Calculate to four decimal places, (including units) using the correct formulas (cited from the course notes or alternate sources using APA 6th, 7th or Harvard referencing.) providing clear sketches as needed.
1. Addendum diameter
2. Pitch diameter
3. Base diameter
4. Dedendum diameter
5. Tooth width (arc length)
6. Tooth width with a 0.01 mm backlash (in mesh)
7. Contact ratio
8. Length of line of access
9. Length of line of recess
10. Length of line of single tooth contact
