Cotta, LLC was proud to participate in the 2nd Annual Academies of Beloit Golf Outing. The Academies of Beloit Golf Outing is an annual charity event supporting the career academies, student certifications, and scholarships at Beloit Memorial High School. The most recent outing was held on Thursday, June 11, 2026 at Glen Erin Golf Club in Janesville, Wisconsin.

The phrase “high-speed gearbox” covers a range of machines that share a speed band but little else. A 20 MW step-up unit linking a gas turbine to a generator and a 500 HP parallel-shaft gearbox on an aerospace test rig both qualify. What they do with the power passing through them, and how they are built, differ completely. The useful way to make sense of the category is to split it in two. Function is what the gearbox does: speed it up, slow it down, reverse it, route it somewhere. Configuration is how the gearbox is put together: parallel shafts, planetary arrangement, right angle, or something else.

The guide in our blog, High-Speed Gearbox Types by Function and Configuration, walks through both, then closes with a framework for matching type to application.

Industrial machinery depends on reliable power transmission between engines and hydraulic systems. The hydraulic pump drive gearbox serves this purpose, converting mechanical power from prime mover sources into the specific input speed and torque characteristics required by hydraulic pumps.

Selecting a hydraulic pump drive gearbox requires understanding your system's power requirements, desired pump speeds, and installation constraints. The number of pumps, their displacement ratings, and operating pressures all influence configuration decisions.

Our blog, Hydraulic Pump Drive Gearbox: What You Need to Know, will help you with this process. https://cotta.com/blog/hydraulic-pump-drive-gearbox-what-you-need-to-know/

Transfer cases are the linchpin in a four-wheel-drive system or any other vehicle that needs to shift power between axles. Born of necessity and evolving with technological progress, transfer cases have morphed from rudimental designs in early vehicles to sophisticated systems in modern machines. Aviation transfer cases provide a parallel example of this evolution, a cornerstone module in the multifaceted power system of a modern aircraft.

As breadth and depth mark the progressive spectrum of transfer cases, understanding the primary types will lay the groundwork for informed decisions – as we provide in our blog, Types of Transfer Cases: A Comprehensive Guide. https://cotta.com/blog/types-of-transfer-cases-a-comprehensive-guide/

Model TR2205 Transfer Case from Cotta is a three-shaft transfer case designed for maximum application flexibility. The T-case has mirror symmetry and provides four identical input/output stations. A disconnect (de-clutch) can be fitted to the I/O stations to provide power interruption, and a special version of the gearbox can be mounted horizontally.

POWER: 600 HP
TORQUE CAPACITY: 2200 lb-ft continuous through gears; 6800 lb-ft continuous through shaft; 17000 lb-ft momentary through shaft
MAX SPEED: 2800 RPM
RATIOS: 1:1 input to output
