Abstract
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.
Highlights
The effects of addendum modification coefficient on the root stresses of spur gear are investigated
The effects of addendum modification coefficient on spur gear tooth stresses are investigated by the finite element method
In the method of changing the pressure angle, tooth thickness is increased by increasing the pressure angle and resulting in decrease of root stresses of the tooth
Summary
The effects of addendum modification coefficient on the root stresses of spur gear are investigated. The effects of addendum modification coefficient on spur gear tooth stresses are investigated by the finite element method. The tooth stresses of positive and negative addendum modificated gears are compared with those of standard gear. In the positive addendum modification, if x increases, tooth fillet stresses will be decreased, tip thickness of the tooth and the contact ratio will be decreased.
