Apar unit Uniflex Cables Gear Oils

Gears are mechanical devices used for transmission of mechanical power and motion. The main function of gear oil is to reduce friction and power consumption. The application criteria set by the gear box manufacturers demand the gear oil not only to perform in adverse conditions like high temperature, lower sump size, low clearance between shaft and gear teeth etc. but also maintain it's properties in high temperature and heavy load conditions. Industrial gears are of two types, enclosed and open. The enclosed gears are lubricated by splash lubrication or a pressure regulating system in which oil is sprayed. In case of open gears the lubricants are applied by hand or by automatic drip or spray method. The choice of oil depends on tooth loading and pitch line speed. In general with increase in tooth loading, viscosity of oil should be increased. Low viscosity gear oils are used for high speed gears.
