Coupling fall into two most important categories: Material Flexing and Mechanical Flexing. The material versatile forms receive their versatility from stretching or compressing a resilient materials, for example rubber, or in the flexing of thin metallic discs or grid. Materials flexing couplings do not demand lubrication, using the exception of grid couplings.

The mechanical flexing couplings accept misalignment from rocking, rolling or sliding of metal surfaces. All metal mechanical flexing couplings demand lubrication.

Materials Flexing Couplings
Materials flexing couplings generally do not demand lubrication and operate in shear or compression and are ready to accept angular, parallel and axial misalignment.

Examples of materials flexing couplings are jaw, sleeve, tire, disc, grid and diaphragm couplings.
– Jaw Couplings

The sleeve coupling transmits minimal to medium torque between linked products in shear by an elastomeric insert with male splines that mate with female hub splines. The insert material is ordinarily EPDM, Neoprene or Hytrel as well as the insert generally is a 1 or two piece design and style.
Moderate misalignment
Torsional dampening (vibration)
Finish float with slight axial clearance
Lower to medium torque, standard objective applications
– Tire Coupling

These couplings possess a rubber or polyurethane element linked to two hubs. The rubber component transmits torque in shear.
Reduces transmission of shock loads or vibration.
Large misalignment capability
Simple assembly w/o moving hubs or linked equipment
Moderate to high speed operation
Broad variety of torque capability
– Disc Coupling
Website Information Picture
The disc coupling?¡¥s principle of operation has the torque transmitted through flexing disc elements. It operates through stress and compression of chorded segments on a prevalent bolt circle bolted alternately amongst the drive and driven side. These couplings are usually comprised of two hubs, two discs packs, in addition to a center member. Just one disc pack can accommodate angular and axial misalignment. Two disc packs are necessary to accommodate parallel misalignment.
? Will allow angular parallel and axial misalignment
? Is a accurate restricted finish float design
? A zero backlash style and design
? Large speed rating and stability
– Diaphragm Coupling
Site Content Picture
Diaphragm couplings utilize just one or maybe a series of plates or diaphragms for your versatile members. It transmits torque from the outside diameter of a flexible plate on the inside diameter, throughout the spool or spacer piece, and after that from inside to outdoors diameter. The deflection of your outer diameter relative towards the inner diameter is what happens when the diaphragm is topic to misalignment. For example, axial displacement attempts stretch the diaphragm which success within a mixture of elongations and bending from the diaphragm profile.
? Makes it possible for angular, parallel and large axial misalignments
? Utilized in large torque, high pace applications
Mechanical Flexing Couplings
The mechanical flexing couplings accept misalignment from rocking, rolling or sliding of metal surfaces. All metal mechanical flexing couplings need lubrication.
Examples of mechanical flexing couplings are gear, grid and roller chain couplings.
– Gear Couplings
Website Material Picture
Gear couplings transmit the highest amount of torque and also the highest volume of torque in the smallest diameter of any flexible coupling.

Every coupling consists of two hubs with crowned external gear teeth. The hubs mesh with two internally splined flanged sleeves which can be bolted together. Gear couplings accommodate angular and axial misalignment through the rocking and sliding of the crowned gear teeth towards the mating sleeve teeth. Parallel misalignment is accommodated by obtaining two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication based on the application. They’re sensitive to lubrication failures but when appropriately installed and maintained, these couplings have a support daily life of 3 to five many years and in some cases they will last for many years.
– Grid Couplings
Weblog Information Image
Grid couplings consist of 2 radially slotted hubs that mesh that has a serpentine strip of spring steel the grid gives torsional damping and versatility of an elastomer but the power of steel. Grid couplings transmit torque and accommodate angular, parallel and axial misalignment from one particular hub on the other as a result of the rocking and sliding of a tapered grid while in the mating hub slots. The grid cross area is usually tapered for improved hub get in touch with and simpler assembly. As there may be motion among contacting hub and grid metal components, lubrication is needed.
– Roller Chain Coupling
Blog Written content Picture
Roller Chain sort couplings consist of two radially sprocketed hubs that engage a strand of double pitch roller chain. Chain couplings are employed for minimal to moderate torque and pace applications. The meshing on the sprocket teeth and chain transmits torque plus the related clearances accommodate angular, parallel and axial misalignment.

Chain couplings need periodic lubrication based on the application. The lubrication is normally brushed onto the chain as well as a cover is employed to aid preserve the lubrication over the coupling.

Mechanical Energy Transmission ¡§C Shaft Coupling substitute technological innovation.
Replaces Spicer, Lovejoy, Beam, Bellows and Jaw variety shaft couplings
EP Coupling would be the newest in shaft coupling style, beam, bellows and jaw couplings all get the job done at substantial speed but lower angle of misalignment.
On the other finish universal joints are able to manage increased quantities of misalignment but at reduce speeds and continuous servicing.
EP Coupling like a hybrid flexible coupling can do the two.
Strengthening on existing coupling technology we offer quite a few diverse versions which allows a 0 to 25?? operational angle of usage
No internal parts ¡§C No bearings to become frequently lubricated and replace , this saves you money and time.
One particular Piece style implies no broken yokes or hubs.
Higher speed- Runs at as much as 7000 RPM
Torsionally rigid at lower angles of misalignment
Scalable ¡§C the EP unit is often scaled up or right down to suit personal client needs.?
Customizable ¡§C Possess a specific form/function the spring/ball settings might be altered to match most applications.
Unique shaft forms or sizes, we do AGMA/ANSI, SAE, & DIN bore/keyway and spline bore?¡¥s.
Being created from two counter wound springs means it absorbs shock force without damage
Spring layout enables greater angle of utilization without damaging parts?
ISO9001 2007 manufactured
The patented EP layout allows for larger angle of utilization without deformation with all the torque transfer seen with Universal Joints, giving the performance of the Universal joint without the constant servicing.
So how does it do the job? The design and style is quite simple, the sets of springs are counterwound so 1 tightens while another loosens and visa versa.
This enables the coupling to operate in the two forward and reverse.
Its simplicity doesn?¡¥t end there, the only thing from the center on the coupling can be a single ball bearing this allows the coupling to pivot allowing for maximum versatility, this suggests no bearings.
Bearings are a consistent maintenance issue, they cannot run in harsh environments like water, mud, sand, dust and dirt as any intrusion by any of those aspects leads to rapid failure.
So no bearings implies no frequent maintenance or worse replacement.
1 piece design and style ¡§C As the product is just hubs and springs the things that can go wrong are greatly reduced, so no cracked yokes or broken propeller joints, no worn out bearings.
Torque ¡§C the bigger the greater The versatile coupling is powered from the springs, but because it is actually a pair of springs it effectively can be a metal bar, add the ball bearing it turns into a versatile metal bar.
So this signifies much more torque and still have the flex that would destroy a standard universal or continual velocity joint.
Substantial speed/low speed ¡§C Now flex coupling engineering is split into two primary areas, substantial speed, low torque, small angle of misalignment and lower speed, increased torque, larger angle of misalignment.
Distinctive couplings applications, same product ¡§C Flexible/High pace couplings are Beam couplings, elastomeric, bellows couplings and jaw form couplings which can run at large speed maintain torsional rigidity but traditionally can only run at a few degrees of misalignment before starting to wear out.
Add to that because of that small misalignment angles , the amount of torque these flex couplings can handle is quite small.
EP?¡¥s versatile coupling remains torsionally rigid at reduce angles at large pace, with far much more torque than say a standard beam coupling, together with the added versatility if necessary.
Decrease speed couplings like universal joints can function at higher torque and larger degrees of misalignment but they have inner components that need to get consistently maintained.
If not greasing for lubrication and bearing replacement along with the angles of misalignment they could work at is constrained as well, as too much will lead to bearing failure.
Our flex coupling can meet the higher torque demands plus the increased versatility while needing no upkeep as you would have to with using universal joints.
One particular product multiple uses. Why would you use different products if you didnt need to when one product will do it all, a no upkeep, higher velocity, high torque, larger angle of misalignment capable flexible coupling.
Three models and counting ¡§C To date we have 3 models the czep150, czep300 along with the czep500
czep150 is capable of handling 150ft lbs of torque and be made use of at 25??.
czep300 is capable of handling 300 ft lbs of static torque and operate at angles of 25??
czep500 can handle 500ft lbs of static torque .
We are looking at what the market demands so bigger or smaller we will be adding far more as time goes on.
We have all the splines and keyways you need to fit your tools.
We want to work with you, so get hold of us and lets operate with each other to solve your flexible coupling issues today.
Viscous coupling is filled with silicone and is not computer controlled. A series of plates with holes and slots turn while in the silicone fluid. Some plates are attached on the front axle driveshaft and some are attached to your rear axle driveshaft. Normally the plates turn at the same rate without relative motion. The silicone fluid becomes very viscous due to it’s viscoelasticity as soon as the plates rotate at differentiating pace. The silicone fluid resists the shear generated in it by the plates with differentiating pace, causing a torque transfer in the faster spinning axle towards the slower spinning axle. Therefore, slight pace difference is needed for torque transfer.
If the rear wheels and driveshaft are slipping and turning faster than the front, friction between the plates increases due to the generated shear from the fluid, slippage is reduced, the rear wheel spin is reduced and the torque from the input shaft is transferred towards the front.
A viscous coupling could be set up in two ways:
viscous coupling acting instead of a center differential
Viscous Coupling Acting Instead Of the Center Differential
In this case, in normal conditions, all power is transferred to just one particular axle. A single part from the viscous coupling is connected on the driving axle, another part is connected towards the driven axle. When driving wheels slip, viscous coupling locks and torque is transferred on the other axle. This is an automatic all wheel drive system.
The disadvantage of the viscous coupling is that it engages too slowly and enables for excessive wheelspin before transferring torque to another wheels. This is especially critical in automatic all wheel drive systems – when cornering under acceleration, the rear end is engaged which has a slight delay, causing sudden change during the car’s behaviour fron understeer to oversteer. Also, when taking-off in sand, front wheels can become bogged down before all wheel drive is engaged.
In an attempt to reduce the coupling’s activation time, czh always transfers 5% of torque to rear wheels (this is achieved by rear driveshaft rotating slower than front driveshaft in normal conditions, causing viscous fluid warm-up and slight solidification).
At the same time, pre-tensioning the coupling too much leads to undesireable transmission wind-up and makes the system too sensitive to uneven tread wear on front and rear tires. This is why Volvo first reduced the pre-tensioning in 2000 after which replaced the viscous coupling with epdex clutch on their all wheel drive vehicles in model year 2003
Viscous Coupling Integrated Into The Center Differential
In this case, all wheels are powered at all times. Viscous coupling is integrated into the center differential. Central differential distributes electrical power to all wheels and lets them turn at distinct speeds while cornering. When excessive wheelspin takes place on 1 of your axles, viscous coupling locks the differential and equalizes the speeds of both axles. Torque is transferred to wheels that have traction. This is often a full-time all wheel drive system.
Viscous coupling can also be integrated into the rear differential.
