The renewed interest in lubricating solutions in gear transmission systems is being driven by more stringent quality standards & operational requirements. To address the industrial challenges of greater load, speed, temperature, and efficiency requirements in different powertrain applications, such as automotive, aviation, and marine, optimized gear lubrication techniques and lubricant formulations are required. Gear lubrication has been the subject of several theoretical and empirical studies, with a focus on lubrication simulation and lubricant formulation. Lubrication techniques and circumstances can be improved to reduce friction, reduce wear and scratching, and improve gear speed. This work evaluates gear lubrication articles with an emphasis on gear effectiveness, contact fatigue, and dynamics in order to assemble and categories major research in an extensive subject with substantial current research. There are also some results acquired by the writers that are included. In this paper, the authors tried to cover all the existing method used to lubricate a gear system and identifies the gap between requirement and existing technology in order to help future researchers in improving lubrication technologies.
