Remote Monitoring Technology

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.

Testing Parts for 3 Decades with Our High-Speed Gearbox

Cotta recently repaired this High-Speed Gearbox Model SN2055-2 which has been in use for over 29 years by a leading manufacturer of security and aerospace products. They have used our SN2055-2 gearbox to test production parts at their facility for almost three decades. Our Genuine Cotta Repair Service begins with a thorough inspection, cleaning and complete evaluation and then, after our diagnosis, only Genuine Cotta Parts are used as replacements during our reassembly process.

Model Series SN2055 High-Speed Gearbox Specifications:

  • Nominal Power of 600 hp
  • Max Output Speed of 30,000 rpm
  • Ratios of 1.29, 2.94, 3.18, 4.26, 6.10
  • Max Accel / Decel Rate of 2,000 rpm/sec at output
  • Approximate Weight of 825 lbs.

Model SN2055 is a foot-mounted, single increasing stage, single output, high-speed gearbox that is designed for test stand use. This model comes standard with a keyed stub input shaft and an aerospace output pad typically AND20007. The input can be driven clockwise or counterclockwise, with the output rotating in the same direction as the input.

Speed Reducers over 30 Years on USCGC Alex Haley

Cotta recently received four speed reducing gearboxes for repair from Lake Union Drydock Company for the USCGC Alex Haley. These gearboxes have been in continuous service for over 30 years and will be rebuilt and returned for installation on the USCGC Alex Haley (WMEC 39) that is currently used for Fisheries Law Enforcement & Search and Rescue missions. Our team was able to efficiently turn this repair around in order to get the vessel back in service for the Coast Guard.

The gearbox repair or refurbish process here at Cotta can take one third the time you would typically expect from specifying, ordering and building an all-new gearbox – saving you downtime and overall cost! Talk to our Repair & Rebuild Services department for more information or to discuss your specific needs!

                   

Genuine Cotta Repair Service: High-Speed Gearbox SN1939-1

Cotta recently repaired this High-Speed Gearbox Model SN1939-1 which has been in use for almost 14 years by a leading aerospace manufacturer of jet engines and related components. Our SN1939-1 gearbox is used to test production parts, such as engine-related components, at their manufacturing facility. During routine preventative maintenance, our customer noticed the gearbox had about a “tablespoon of metal debris” that collected on a magnet at the bottom of the gearbox. From our inspection here at Cotta, we found one bearing wasn’t spinning freely on the high-speed shaft – which we discovered also had a small chip in the shaft. Our Genuine Cotta Repair Service begins with a thorough inspection, cleaning and complete evaluation and then, after our diagnosis, only Genuine Cotta Parts are used as replacements during our reassembly process.

Model Series SN1939 High-Speed Gearbox Specifications:

  • Nominal Power of 600 hp
  • Max Output Speed of 30,000 rpm
  • Ratio Range up to 14.40 overspeed
  • Max Accel / Decel Rate of 2,000 rpm/sec at output
  • Approximate Weight of 1,600 lbs.

Model SN1939 is a foot-mounted, two-stage increasing, two output, high-speed gearbox that is designed for test stand use. This model has a stub input shaft and two aerospace output pads typically AND20006. Both output pads have the same direction of rotation and the same ratio. There is a special design option to have a different ratio on each output. Contact Cotta engineering for information on per head power capability.

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

Approximate Weight:  2800 LB

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
