Gearbox lubrication serves as the foundation for reliable power transmission performance across industrial equipment. The correct lubricant creates an oil film between gear teeth and bearings, separating metal surfaces under extreme contact pressures that can exceed 1 GPa. Without proper lubrication, friction generates excessive heat, accelerates wear, and leads to catastrophic failure, resulting in unplanned downtime and costly repairs.

The choice depends on multiple factors: peripheral speed, operating temperature ranges, load conditions, and gear system design. At Cotta, our 120 years of power transmission expertise has shown that matching lubrication methods to specific applications dramatically extends component life.

Model GO1900E Speed Increaser from Cotta is a single-stage increasing gearbox designed for direct mounting to industrial engines via an SAE fl**ge and driven in standard engine rotation (clockwise facing input shaft). This unit incorporates an idler shaft to provide output rotation same as input.

OUTPUT ROTATION: Same as input
MAX INPUT TORQUE: 7900 lb-ft
MAX INPUT SPEED: 2500 RPM or as otherwise limited by input clutch or coupling
MAX OUTPUT SPEED: 4800 RPM
RATIO RANGE: 1.76 to 3.54

Speed increasers multiply rotational speed at the output shaft. As output speed goes up, output torque goes down. This inverse relationship makes rating specifications different from those used for speed reducers. Three specifications determine whether a speed increaser matches your application. These are torque rating, horsepower capacity, and service factor.

Each one addresses a different aspect of gearbox performance. Selecting the wrong ratings leads to problems. Bearings fail early. Gears wear faster than expected. Heat builds up beyond what the gearbox can handle. The right specifications prevent these failures and extend service life.

Our blog, Power Ratings for Speed Increasers, explains how to read, interpret, and calculate each rating specification for speed increaser applications. https://cotta.com/blog/power-ratings-speed-increasers/
