Gear Lubricant Selection

In a previous article we introduced selection criteria for a few common types of machine components, including geared components and gear drives. This time we’ll more thoroughly discuss the general concepts that appeared in the previous article.
 Geared components are widely used in manufacturing all types of products and in the operation of many of those products by the end-user. Geared components perform the function of either increasing or decreasing shaft speeds for applied torque/force.

This article will provide advice for selecting lubricants for gear reducers based on both AGMA and ASM (American Society of Materials) methods. Those methods take into consideration the gear type, speed, operating sump temperature and base oil viscometric (i.e., viscosity index) properties to find the lubricant that represents the best fit for the application.
