Whole Field Analysis of Asymmetric Helical Gear Using Photo Stress Method and FEA Method

Objectives: To carry out dynamic state analysis of asymmetrical helical gears for contact stresses using photo stress technique and suitable finite element software. Methods: Currently the Hertz equation is used to calculate which based on certain speculations. The value load transmitted by a gear may be known but whether it taken single or more pairs teeth are some assumptions thus calculated not true stresses. get precise evaluation field in tooth decided experimental work asymmetric actual working condition. method only provide magnitude also gives idea about distribution gear. Finite validate results. Findings: values obtained photostress FEA has minimum error 2.17% maximum 8.89% respectively. less than 10% within limit. We can observe close agreement between these two methods. Novelty: This study provided accurate result theoretical calculation. Photostress one best test methods with different torque condition that Maximum been found method.
