Speed Increaser Designed for Test Stand

Cotta’s high-speed gearboxes are built to provide many years of service, which is a reason why some of the largest OEM companies in the world have come to Cotta for custom built gearbox solutions.  In addition to designing high-speed gearboxes for speed management in non-aviation and industrial applications, where highly-specialized, powerful and reliable solutions are needed, Cotta has also designed numerous gearboxes for R&D and production test stand applications for automotive, aerospace, and industrial components.

Cotta’s engineering team designed this high-speed gearbox that will be used in a test stand for an aerospace application.  After the assembly process is completed, additional quality checks will be made on the gearbox as it goes through testing in Cotta’s high-speed programmable test cell.  See gearbox specifications below:

Pump Drive Used in Rope Shovel

Cotta’s complete product line has been supporting a wide variety of industries and applications for years, where demanding performance is required under the most extreme conditions and challenging environments. The mining industry is one of those industries in which Cotta continues to meet the high performance requirements of customers.  The process involved in the mining industry can be difficult.  The equipment used is often operated in very remote locations with highly variable rock and operating conditions, therefore the reliability and durability of the equipment is essential as it saves on down time and money.

Cotta is currently in the process of assembling a pump drive that will be used in a rope shovel.  This application is a bucket equipped machine that is used for digging and loading earth or fragmented rock for mineral extraction.

SEE SPECIFICATIONS BELOW:

Ratio:  1.0 to 1.0

Max Torque:  4920 FT-LB

Max Speed:  1100 RPM

Max Power:  1030 HP

Max Power Per Pad:  257 HP

Assembly Complete on Creep Drives

Cotta Transmission just completed assembly on additional creep drives that will be used in a guardrail truck application.  Cotta has been supplying the creep drives to a customer for over 10 years.  The units allow the guardrail trucks to creep along at a very low consistent speed without being affected by the engine speed.  This allows the auxiliary systems to utilize the required power to effectively perform the work that is needed.  Once the system is disengaged, the vehicle is then able to drive at a normal speed.

Specifications:

  • Ratio: 3 : 1
  • Max Torque: 1250 ft lbs input PTO mode, 12500 ft lbs thru mode
  • Approximate Weight: 390 lbs
  • Oil Capacity: 12 quarts

Custom Speed Reducer Gearboxes – Numerous Sizes

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

Cotta Wet Clutch Gearbox Technology

In response to customer demand, Cotta has developed a new line of wet clutch transmissions based on our most popular products.  These products take reliability, durability, and ease of use to a new level in the most demanding applications.  Cotta’s wet clutch option is an industry leading technology which provides lower maintenance, extended clutch life, and remote actuation for ease of operations.  Gearboxes utilizing dry clutches require manual actuation via a gearbox mounted to a mechanical or pneumatic system.  Cotta’s wet clutch designs can be actuated via an electrical switch, dramatically improving equipment ergonomics. Other benefits of Cotta’s wet clutch system are the elimination of periodic clutch adjustments, dramatically increased service intervals, and extended clutch life, all leading to lower total ownership costs.

Cotta’s SR2347E product family can handle applications up to 1,000 HP, and is designed for applications where direct engine, high HP reduction gears or speed increasers are needed.  The SR2347E units are ideal for industrial, oilfield, and mining industries.

Typical Applications:

  • Compression
  • Drilling
  • Pumping
  • Dredging
  • Process Machinery
  • Shredding
  • Crushers
  • Conveyors

Contact your Cotta sales representative for details and information on how Cotta’s wet clutch products can save you time, money, and improve total life cycle cost.
