In this paper, the gear contact evaluation models developed using various methods have been discussed. The new experimental and numerical methods have been presented. The research papers are classified into frictionless and frictional contact stress analysis and subdivided into experimental and finite element models. This paper will provide researchers with various information and huge literature data on the described subject. It serves as the rapid retrieval of data related to gear contact stress evaluation. Furthermore, a comprehensive discussion focusing on the customized experimental test rig (Gear Dynamic Stress Test Rig) has been done. Also, the finite element (FE) results showing the variation of contact stresses with and without friction, along the contact path has been shown. The FE results revealed that the contacting stresses between the gears increased significantly for different parallel axis gear, for a given coefficient of friction rise considered in the study.
