Industrial, Commercial, Marine & Agricultural
CVO Inc. can design and manufacture CV shafts for Ag and Industry. Our designs are working in food processing, mills, pumps, dynamometers, rollers, generators etc. CVO Inc. can refit many outdated designs into a more efficient (production and energy savings) design. CVO Inc. can design CV shafts for high angle needs as well as high RPM requirements. With CV joints that can plunge and articulate CVO Inc. can fit a CV shaft to your needs. CVO Inc. can supply joints that articulate up to 50° degrees. We also offer a special application CV that can work at 70° degrees. Used in the Massey Ferguson 4X4 tractor. Oil bath applications, forced lubrication or oil mist lubrication for environments that are too severe for a boot. CVO Inc. can provide a solution for your power transmission needs from propeller (prop) shafts, to irrigation, short coupling to telescoping. From concept to design, 3D modeling, to prototype and production.
Constant Velocity Joints for Industrial Machines:
Industries who use CV- Military, Steel mills, Wood mills, Marine, Mining, Bottling plants, Textile mills, Tube mills, Roll forming mills, paper mills, PHEV, ConVel CV joints or complete replacements for discontinued parts.
Universal joints to CV joints - Design new CV shafts to replace universal joints improving performance (see graphs below).
Refurbishing or improving on existing CV shafts. Some designs are out of date or no longer manufactured. CVO Inc. can make replacement shafts with more readily available CV joints. Retro-fitting universal joint designs to CV joints make your machines run smoother with reduced wear. CVO Inc. can repair some out of date Con Vel type CV joints.
Additional benefits of using CV joints are a greener more efficient shop using less power & labor to produce the same qty of better quality products. Using less power either by running less time to make the same number of parts or producing more in the same amount of time resulting in a decreased energy bill reducing your carbon footprint.
CVO Inc. is now a NTN distributor of industrial CV joints.
CVO Inc. now manufactures two CV joints of our own design. Two more in 2010
CVO Inc. can supply GKN and Convel industrial CV joints.
Dimensional sizes from 1" TRI-BALL joints to 28" DOJ
Torque ranges from 1 kgf·m to 9000+ kgf·m
Proof CVO Inc can improve performance.
With u-joints there was a 4.7 ft/min fluctuation in velocity.
With CV joints there was a 68% reduction in velocity change to 1.5 ft/min as seen in the before and after charts above. The velocity change now present is due to other reciprocating components on the machine. CV joints result in a smoother more consistent delivery of torque. This is actual data from a customer's equipment before and after CV. After several months of operation there has been a 25% reduction in out of spec product. CV assemblies also reduce wear and tear on bearings at connection points further reducing maintenance downtime and increasing production capacity in speed and up time.
In the tougher economy CV shafts save far more than the added cost. CV shafts are more expensive than universal joint shafts though the difference is easy to justify in the savings. Many of our customers are looking for ways to improve financially, environmentally (workplace and world) and productively.
Easier to maintain
CV joints can be maintained with minimum shop requirements in most applications, meaning the CV shaft can be repaired on site without much downtime and without the need to purchase another complete unit. Many times universal joint shafts in industrial applications are run until the unit is no longer serviceable requiring a complete replacement.
Less wear on associated equipment
While physics laws are constants the added effect of increasing and decreasing velocity is eliminated with CV shafts reducing the wear on bearings/bushings to the laws of physics and not imparting additional wear/ cost induced by the shaft.
Better material control
In the above graphed study one of our customers shows the before and after results of switching to CV shafts.
Less downtime
If a shop maintains its own equipment a CV joint can be removed and replaced in short order with simple tools with the shaft back in service quickly. Further since the CV joint is not self destructive at angles the CV shaft will typically last longer before needed maintenance.
Reduced electric
The obvious savings here is less waste in product resulting in less runtime for the same yield. The other is there is less power requirement to turn the shaft itself resulting in power savings.
Quieter operation
Since the CV shaft does not induce any velocity associated harmonics the shaft portion will run quieter. Another plus, depending on what design best fits the application there are some CV joints that allow for axial movement these can isolate harmonics and vibration induced from a portion of the dive or driven end from being transmitted through the shaft resulting in reduced noise and increasing the life of associated components.

Our own CV joints. We have begun production of our own CV joint design. We have two sizes offered for small to mid-range torque loads. This is in addition to the NTN product we are offering.
CVO Inc. uses Solid Works 2010 Premium with Simulation for development and design.
CVO Inc. is a NTN industrial CV joint distributor.
CVO Inc. can supply GKN, or Convel industrial CV joints.
The shaft in the right front is a ConVel CV used in mining it is no longer in production. We are working on making quality replacements for these. The CV shaft (left front) is a 1 ton GMC/Chevy. The Small CV joint is ATV product and the CV in the rear is a large design with many industrial applications. It has custom designed flanges to bolt where an existing u-joint shaft was installed. This allows customers to implement CV shafts without modifying equipment.

Special Vehicle designed to fit in the V22 Osprey (picture courtesy of pentagon.mil).
This vehicle required custom axles to fit the requirements of
our customer. CVO Inc. designed and produced axles that have not failed
after extensive testing which resulted in failure of other components.
Prior to CVO Inc. the customer could not obtain an axle that would last more than
fifteen minutes. Other than a test to failure, on a machine designed to break the axle,
none of our product has failed as of this writing 08-07. ( our first unit was produced 11-06)

CV joints are excellent alternatives to u-joints. Get more power with less vibration and noise caused by the driveshaft. Diesel power + CV Shaft = Less fuel consumption @ same RPM + quieter ride.
CVO Inc. produces CV shafts for high end wood mills and tube mills. Speeding production by reducing the vibration and feed rate problems caused by u-joints. CVO Inc. designed a high speed replacement shaft for a company that uses McKenica tube mills. This shaft improved production for the company (see graph at the top of this page). This shafting yielded the results posted above in the graph.
