Solved Examples for Spur Gear Design Contact Ratio Two 20 full-depth gears have a diametral pitch of 6 and operate on a centre distance of 7.5 in. The speed ratio is 15:1. Find the contact ratio. (Example 10.7, page 535, Spotts 7th edition) Long and Short Addendum System Find the shift in the position of rack necessary to eliminate undercutting in a 14.5 fulldepth gear of 18 teeth. Diametral pitch is 1. (Example 10.8, page 539, Spotts,7th edition). Find the thickness of the tooth on the pitch circle for 14.5 gears, if shift to avoid interference is taken as 0.5 in for Pd = 1(Example 10.9, page 539, Spotts, 7th edition). Force analysis in spur gear Example 13.5, page 862, Shigley, 6th edition. Example 17.2, page 660, Bhandari, 3rd edition Spur Gear Design for bending strength considering dynamic load based on velocity ratio. Example 17.7, page 681, Bhandari, 3rd edition Spur Gear Design for bending strength considering dynamic load based on Buckingham equation and for wear strength Example 17.9, page 683, Bhandari, 3rd edition
