Lubrication Selection for Enclosed Gear Drives
Compounded gear oils are used primarily to lubricate enclosed worm gear drives, where the high sliding action of the gear teeth requires a friction-reducing agent to reduce heat and improve efficiency. The surface active agent, which is a fatty or synthetic fatty oil, prevents sliding wear and provides the lubricity needed to reduce sliding wear.
