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 CVO Inc. can refit many outdated designs into a more efficient (production and energy savings) design.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 (we have these in stock). 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.

Industries who use CV- Military, Steel mills, Wood mills (Weinig Moulder), Marine, Mining, Bottling plants (rinsers, fillers, packaging etc.), Grain Mills, Textile mills, Tube mills Mill Master and McKenica, Roll forming mills (brass, aluminum, copper), paper mills production (drier, press roll) and finished (folding, printing etc.), food (improved Krones labeling shafts) and beverage processing and packaging, Testing and Chemical industry, Film industry, PHEV, ConVel CV joints or complete replacements for discontinued parts. Sometimes called propshafts, coupling shafts or driveshafts these terms are generic as there are many types CVO Inc. works solely with true constant velocity joints and shafts.
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 Some designs are out of date or no longer manufactured.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 CVO Inc. can repair some out of date Con Vel type CV joints. Replacement shaft for MCI coaches cooling fan shafts that fail in less than a year.
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.

Types of CV shafts and usage
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. The above results were before and after on a McKenica tube mill. The above data was provided by the customer, CVO Inc. was not involved in the testing or obtaining of the data.
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.
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.
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.
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 drive or driven end from being transmitted through the shaft resulting in reduced noise and increasing the life of associated components.
In many cases CV joints last longer than U-Joints due to the non self-destructive nature of the CV joint. This mitigates the additional cost of the CV joint shafts and reduces maintenance overhead.

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 2013. ( our first unit was produced 11-06)
2010 CVO Inc. has produced over a thousand units for this project.

Thanks for the pictures. When I grease the machine I check for play in the shaft. I saw a very small amount of play perpendicular to the shaft and rotationally that I had not noticed before. Because of the length of time it has run and the short life span of the old shaft I thought I should change the joints out at the first signs of wear just to be sure. I am very impressed with the drive shafts performance and happy to know that it could have run longer yet. Changing to the cv style shaft has saved us thousands of dollars. You should advertise this drive shaft in some of the hardwood lumber magazines. There are quite a few of these machines out there and the all have the same problem with the drive shaft. I just got tired of fixing it and spending all that money for something I knew was going to fail so I started searching for someone who specialized in cv joints, and I found your website. If you are interested in advertising I can give you the names of some of the magazines I think it would be worth considering.
