The Effects of Addendum Modification Coefficient on Tooth Stresses of Spur Gear

The effects of addendum modification coefficient on the root stresses of spur gear are investigated. By considering positive and negative addendum modificated gears, distributions of root stresses are determined by the finite element method. The root stresses of addendum modificated gears are compared with those of standard gears. The problem is analyzed as one in the plane stress and, also the plane strain.
