Speed Reducers

For over 100 years Cotta has been making American made high performance speed reducers. Our long history of precision engineered gearboxes is reflected in the durability and reliability of our speed reducers, which are designed to get the most out of your heavy-duty industrial equipment through the use of gear trains.

Speed Reducer in a Nutshell

A speed reducer, also known as a gear reducer or gearbox speed reducer, minimizes the speed of a motor or engine while simultaneously increasing its output torque. This is achieved through a gear train, which transmits power from the input shaft to the output shaft.

Speed reducers are vital components in equipment operation, enabling motors to function at optimal speeds while delivering the necessary torque for various applications. They help enhance efficiency, lifespan of the motor, as well as minimizing energy consumption.

Worm gear reducers are popular in various industries due to their compact design and low maintenance. They use a worm gear and worm wheel to achieve high gear ratios, delivering high torque at low speeds. They come in various sizes and configurations, offering speed reduction ratios like 10:1, 15:1, 20:1, 30:1, 40:1, or 50:1. The output shaft can be hollow or solid and may feature left or right-hand threading. Some models of a worm gear reducer also offer double-projecting output shafts for added installation flexibility.

Designed for Maximum Efficiency

Cotta Speed Reducers match the engine speed to the optimal driven equipment speed so both can run at peak efficiency.

Cotta’s gearboxes and gear motors are used in many demanding applications, including masthead drills, and ancillary machinery. Reducing motor speed is crucial in various industrial applications, and Cotta speed reducers and even speed increasers achieve this by lowering the rotational speed of motors while increasing output torque.

Whether diesel engines, electric motors or PTO’s Cotta speed reducers get the job done in the toughest environments.

Custom Solutions for Your Application

We also know that every application is different. That’s why we offer custom-engineered speed reducers to fit your specific needs. Cotta custom speed reducers are designed to optimize output torque for various applications.

Cotta works with your team to gather critical information such as input speed, output speed, flywheel housing size, and direction of rotation to recommend the best solution. Calculating the reduction ratio is crucial to ensure the desired output rotational speed and optimal performance for your specific application. We have expertise in custom speed reducers for high RPM applications so your equipment can perform at its best regardless of industry. Cotta has expertise in custom speed reducers that efficiently transfer power from the motor shaft to the output shaft.

Gear Reducer Installation and Maintenance

Cotta speed reducers require rear support and are clockwise when facing the input shaft. Some Cotta speed reducers operate at a right angle to the motor shaft, providing space-saving benefits. To get the most out of your gearbox and longest life, you must lubricate the gearbox with gear oil before use and follow recommended maintenance procedures to ensure the longevity of the output shaft and overall gearbox.

Testing and Gear Reducer Quality Assurance

All Cotta speed reducers are tested at our state-of-the-art facility to meet the highest quality standards. Cotta’s testing procedures ensure optimal torque output for all speed reducers. Our test lab located in Beloit, WI has high RPM testing capabilities to give you a comprehensive look at the gearbox performance before it ships. With our zero-defect policy every product is inspected in detail to ensure reliability in the toughest applications.
