Don't Forget the Gear
COMMON GEAR TYPES Don’t Forget the Gear Oil Gear oil is often overlooked when it comes to scheduled maintenance. Gear Oil Basics additives in order to reduce wear and High-quality gear oil must lubricate, extend gear and bearing life. cool and protect geared systems. Additional Differences It must also carry damaging wear Because many of the components debris away from contact zones and found in the drivetrain consist of ferrous SPUR GEARS STRAIGHT muffle the sound of gear operation. material, the lubricant must prevent BEVEL GEARS Differential, standard transmission and Transmissions rust and possible corrosion to other industrial machinery gears often require Industrial Equipment materials. Rust and corrosion problems extreme-temperature and pressure Some Differentials are not nearly as prevalent in engines. protection in order to prevent wear, pitting, spalling, scoring, scuffing and The many small and intricate other damage that result in equipment components that make up gear failure and downtime. Protection against sets can be quite noisy and may oxidation, thermal degradation, rust, be subjected to shock-loading. The copper corrosion and foaming is also viscosity and extreme-pressure important. formulation of gear oil quiets gears and dissipates shock-loading. Gear Oil and Motor Oil Are Not the Same The rotating motion of the gear sets also Gear oil differs from motor oil. While tends to churn the lubricant, leading SPIRAL BEVEL WORM to foaming. If a gear lube foams, its GEARS GEAR SET many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 load-carrying capacity is significantly Industrial Equipment Gear Reduction motor oil, they are actually the same reduced because the air suspended Some Differentials Boxes viscosity; the difference is in the within the oil is compressible.
