Cotta recently designed and built this new Wet Clutch Gearbox Model SR2347E for a hydraulics and tooling company in Colorado. Our Model SR2347E is a single-stage reduction gearbox designed for direct mounting to industrial engines via an SAE flange and driven in standard engine rotation (clockwise facing input shaft). This unit incorporates an idler shaft to provide output rotation same as input. The SR2347 Speed Reducer features a Cotta multi-disc wet type master clutch and is coupled to the engine via a torsional dampener. Our wet clutch option provides lower maintenance, extended clutch life, and remote actuation for ease of operation. This particular SR2347E for our customer includes Remote Monitoring capability, allowing them to view real-time performance parameters of specific gearbox functions on a customized dashboard accessed via webpage.

Model Series SR2347E Wet Clutch Gearbox Specifications:

  • Max Input Torque of 2600 lb-ft.
  • Max Input Speed of 2,200 rpm, or as otherwise limited by flywheel coupling
  • Ratio Range of 1.28 to 3.0
  • Output Shaft of 4″ diameter, 9″ long, 1″ x ½” keyway at a standard 6 o’clock position
  • Approximate Weight of 1,600 lbs.

Our SR2347E units are ideal for industrial, oilfield and mining applications up to 1,000 hp and are designed for applications where direct engine, high HP reduction gears or speed increases are needed. For more information about Cotta Wet Clutch Gearboxes, visit this page.

     

Cotta offers industry-leading Remote Monitoring capabilities for many of our gearboxes, allowing the user to view real-time performance of specific gearbox functions. A variety of parameters can be viewed on a customized dashboard accessed via webpage. Critical decisions, such as scheduling routine maintenance, can be made without onsite physical inspection of our gearbox – saving both time and money. Remote Monitoring is ideal on equipment operating at remote locations for applications like mining, oil & gas, wastewater, environmental utility, and many others. Let’s talk about how this capability may be able to fit your specific needs! Visit our Remote Monitoring Webpage for more information.

Cotta Model GR16E is a single-stage reduction gearbox designed for direct mounting to industrial engines via an SAE flange and driven in standard engine rotation (CW facing input shaft). This unit incorporates an idler shaft to provide output rotation same as input. Our speed reducers match the optimum engine speed to the optimum driven equipment speed, allowing your engine and load to both operate at ideal efficiency.

Typical uses include pumps, dredges, compressors, crushers, drills and high-performance machinery for oil & gas, construction, mining, and other industrial applications. Our heavy-duty gearboxes are designed for use with diesel engines, electric motors, PTO’s, and other prime movers. This particular unit here is a replacement GR16E401-1 Speed Reducer which will be used in the forestry market on a Morbark Tub Grinder in New Hampshire to chip limbs and branches. Cotta has supplied replacement gearbox units as well as service parts for many years for Morbark Tub Grinders worldwide.

Model GR16E Speed Reducer Specifications:

  • Max Input Torque of 1650 lb-ft.
  • Max Input Speed of 2200 RPM or as otherwise limited by input clutch or coupling
  • Ratio Range of 1.50 to 3.0
  • Integral foot mounts and integral lube pump supplied
  • Approximate weight of 1,500 lbs.

Cotta Transmission gearboxes are personally crafted to meet your requirements, and are some of the most reliable, durable, and powerful products available in the industry. Cotta works with each customer to discover their specific needs, uncover the power issue causing problems, and designs the best possible product to overcome the challenges that the application presents.

For example, Cotta designed a top mast drive from the ground up specifically for a customer’s blast hole drilling application. The bearing arrangement on the output shaft was designed to have as much downward force as upward force on the bearings, which is a very desirable feature for a blast hole top mast drive. A typical top head will have the bearing configuration on just one side so that all of the steel can be held up in the air with the appropriate amount of pressure on the bit while drilling. Cotta’s solution was designed with our customer to meet their unique requirements for pushing down or pulling up. The greater down force gives the end user the ability to drill the blast holes faster. Cotta’s custom top mast drive has proven to be a strong and reliable product for the customer for over 30 years.

Cotta has over 2,000 existing product designs available, and an experienced engineering team that can take any new transmission application from concept to delivery at our production facility in Beloit, WI.

NLB Corporation has been leading the way in water jet productivity since 1971, offering a wide range of high-pressure and UHP water jet pump units, water blasting equipment and accessories.  NLB had been using Horton Clutch prior to switching over to Cotta Transmission almost 20 years ago.  Since switching suppliers, NLB has had great success using Cotta gearboxes on all of their truck mounted systems.

The NLB Starjet is a self-contained system with rotating water jets on a robotic arm that is mounted to the front of a truck.  The Cotta gearbox is being used as a creep drive to give the trucks a controlled and precise travel speed.  The Starjet System is used to remove pavement markings, as well as runway rubber buildup. The travel speed is very important when utilizing high pressure water (40,000 PSI).  If the travel speed is too fast, the required marking will not be 100% removed.  If the travel speed is too slow, the base surface could be damaged. The creep drive that NLB uses has a minimum travel speed of 10 ft/minute to a max speed of 350 ft/minute. The system will hold the set speed whether the equipment is full of water or empty of water, going uphill or downhill.  This precise travel speed allows NLB’s customers to perform flawlessly over the competition that uses other gearboxes.

 

NLB Corporation is launching their newest model Starjet SRV-7 that also uses a Cotta gearbox.
