The flow of the medium at the mesh area of a helical gear has been visualized by the experiment using transparent acrylic gears and a water tank. Among two major roll of lubrication, reducing friction and cooling, cooling is quite important for maintaining gear durability because high temperature has metallurgical effect. Lubrication also makes excess power loss by squeezing effect at mesh area as well as by various losses existing in feeding system such as pump loss. Therefore, for the efficient contribution of lubricant, it is necessary to find an optimum arrangement of oil feeding especially for the purpose of cooling. This paper has described how to visualize the flow of the medium of the engagement part whose observation was not completed by the conventional method. The flow at mesh end region was observed clearly through gear body by using milk or plastic particles.
