Custom Speed Reducer Gearboxes – Numerous Sizes

Custom Speed Reducers

Cotta’s long tradition of manufacturing the highest quality gearboxes, American-made for more than a century, is exemplified in our extensive line of speed reducers.  Compact and rugged, Cotta’s engine mounted speed reducers are designed to meet the demands of modern diesel engines. Cotta offers standard models, or will design a custom gearbox for your application.  The reducers are furnished with bell housings to mount directly to the engine’s SAE flywheel housing.

Speed reducers are available in increasing sizes nominally 100 HP to 2200 HP, and with flywheel housing sizes from SAE 4 to 00.  At approximately 2200 HP capacity, the gearboxes become physically too large to direct mount at which point independent mount gearboxes are offered.

Speed reducers can be coupled to the engine by a variety of methods, including clutches, drive plates, or torsional couplings depending upon the application requirements.

Some reducers are suitable for driving side pull loads using belts or chains on the output shaft. Consult with Cotta Engineering before selecting a gearbox for use with a side pull load.

Cotta’s speed reducer catalog is organized into a standard-ratio section and a high-ratio section with each sorted from smallest to largest by power capacity. These gearboxes are considered “standards”, but are not the only reducers available.  Cotta offers modified standard boxes, as well as full-custom and purpose-built boxes.

Cotta speed reducers have been used in numerous applications, some of which are listed below:

  • Pumps
  • Compressors
  • Gen-sets
  • Rock crushers
  • Wood chippers
  • Shredders
  • Dredges
  • Snow Blowers
