Coupling fall into two main classes: Material Flexing and Mechanical Flexing. The materials versatile varieties get their versatility from stretching or compressing a resilient materials, for example rubber, or in the flexing of thin metallic discs or grid. Material flexing couplings never require 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 call for lubrication.

Material Flexing Couplings
Materials flexing couplings usually tend not to call for lubrication and operate in shear or compression and therefore are capable to accept angular, parallel and axial misalignment.

Examples of material flexing couplings are jaw, sleeve, tire, disc, grid and diaphragm couplings.
– Jaw Couplings
Blog site Information Image
The jaw coupling is usually a material flexing coupling that transmits torque thru compression of an elastomeric spider insert placed between two intermeshing jaws.
Flex element is normally manufactured from NBR, polyurethane, Hytrel or Bronze
Accommodates misalignment
Transmits torque
Used for torsional dampening (vibration)
Low torque, common function applications
– Sleeve Coupling

The sleeve coupling transmits very low to medium torque between connected tools in shear by means of an elastomeric insert with male splines that mate with female hub splines. The insert materials is ordinarily EPDM, Neoprene or Hytrel as well as insert generally is a one particular or two piece layout.
Reasonable misalignment
Torsional dampening (vibration)
Finish float with slight axial clearance
Reduced to medium torque, basic objective applications
– Tire Coupling

These couplings possess a rubber or polyurethane element linked to two hubs. The rubber element transmits torque in shear.
Reduces transmission of shock loads or vibration.
Substantial misalignment capability
Easy assembly w/o moving hubs or linked products
Moderate to higher velocity operation
Broad variety of torque capacity
– Disc Coupling
Web site Material Picture
The disc coupling?¡¥s principle of operation has the torque transmitted as a result of flexing disc factors. It operates as a result of stress and compression of chorded segments on the common bolt circle bolted alternately concerning the drive and driven side. These couplings are ordinarily comprised of two hubs, two discs packs, and also a center member. A single disc pack can accommodate angular and axial misalignment. Two disc packs are needed to accommodate parallel misalignment.
? Makes it possible for angular parallel and axial misalignment
? Is usually a accurate restricted end float layout
? A zero backlash layout
? High pace rating and balance
– Diaphragm Coupling
Site Information Picture
Diaphragm couplings make use of just one or maybe a series of plates or diaphragms for your versatile members. It transmits torque from your outside diameter of the flexible plate to the inside diameter, across the spool or spacer piece, then from within to outdoors diameter. The deflection on the outer diameter relative on the inner diameter is what takes place when the diaphragm is subject to misalignment. For instance, axial displacement attempts stretch the diaphragm which results within a blend of elongations and bending with the diaphragm profile.
? Permits angular, parallel and high axial misalignments
? Used in higher torque, high speed 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
Site Written content Image
Gear couplings transmit the highest volume of torque plus the highest amount of torque from the smallest diameter of any versatile coupling.

Each coupling includes two hubs with crowned external gear teeth. The hubs mesh with two internally splined flanged sleeves which are bolted collectively. Gear couplings accommodate angular and axial misalignment through the rocking and sliding in the crowned gear teeth towards the mating sleeve teeth. Parallel misalignment is accommodated by getting two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication depending on the application. These are sensitive to lubrication failures but when appropriately set up and maintained, these couplings possess a service lifestyle of three to 5 many years and in some cases they can final for many years.
– Grid Couplings
Weblog Articles Picture
Grid couplings include two radially slotted hubs that mesh having a serpentine strip of spring steel the grid gives torsional damping and flexibility of an elastomer but the power of steel. Grid couplings transmit torque and accommodate angular, parallel and axial misalignment from one hub to the other via the rocking and sliding of the tapered grid in the mating hub slots. The grid cross section is generally tapered for far better hub make contact with and less difficult assembly. As there may be movement concerning contacting hub and grid metal elements, lubrication is required.
– Roller Chain Coupling
Website Information Image
Roller Chain sort couplings include two radially sprocketed hubs that engage a strand of double pitch roller chain. Chain couplings are utilised for reduced to reasonable torque and speed applications. The meshing of the sprocket teeth and chain transmits torque along with the connected clearances accommodate angular, parallel and axial misalignment.

Chain couplings call for periodic lubrication based on the application. The lubrication is ordinarily brushed onto the chain as well as a cover is made use of to help retain the lubrication around the coupling.

Mechanical Energy Transmission ¡§C Shaft Coupling substitute technological innovation.
Replaces Spicer, Lovejoy, Beam, Bellows and Jaw form shaft couplings
EP Coupling is the most recent in shaft coupling layout, beam, bellows and jaw couplings all get the job done at substantial velocity but minimal angle of misalignment.
Within the other finish universal joints can manage larger amounts of misalignment but at lower speeds and constant upkeep.
EP Coupling like a hybrid versatile coupling can do each.
Bettering on existing coupling technologies we give many distinct versions which permits a 0 to 25?? operational angle of utilization
No inner elements ¡§C No bearings to become frequently lubricated and change , this saves you time and money.
One Piece layout implies no broken yokes or hubs.
Substantial speed- Runs at as much as 7000 RPM
Torsionally rigid at minimal angles of misalignment
Scalable ¡§C the EP unit is often scaled up or right down to suit person buyer needs.?
Customizable ¡§C Have a unique form/function the spring/ball settings can be altered to match most applications.
Various shaft forms or sizes, we do AGMA/ANSI, SAE, & DIN bore/keyway and spline bore?¡¥s.
Being produced from two counter wound springs signifies it absorbs shock force without damage
Spring style and design makes it possible for greater angle of utilization without damaging elements?
ISO9001 2007 manufactured
The patented EP style and design lets for larger angle of usage without deformation together with the torque transfer seen with Universal Joints, giving the performance of a Universal joint without the constant maintenance.
So how does it perform? The layout is quite simple, the sets of springs are counterwound so a single tightens while the other loosens and visa versa.
This allows the coupling to function in the two forward and reverse.
Its simplicity doesn?¡¥t end there, the only thing during the center from the coupling is usually a single ball bearing this allows the coupling to pivot allowing for maximum flexibility, this signifies no bearings.
Bearings are a continuous servicing 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 usually means no frequent servicing or worse substitute.
A single piece layout ¡§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 much better The versatile coupling is powered from the springs, but because it is often a pair of springs it effectively is usually a metal bar, add the ball bearing it turns into a versatile metal bar.
So this suggests much more torque and still have the flex that would destroy a standard universal or consistent velocity joint.
Higher speed/low speed ¡§C Now flex coupling technological innovation is split into two main areas, substantial velocity, low torque, small angle of misalignment and reduce velocity, increased torque, larger angle of misalignment.
Distinct couplings applications, same product ¡§C Flexible/High velocity couplings are Beam couplings, elastomeric, bellows couplings and jaw sort couplings which can run at large velocity 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 sum of torque these flex couplings can take care of is quite small.
EP?¡¥s versatile coupling remains torsionally rigid at reduced angles at high velocity, with far extra torque than say a standard beam coupling, together with the added flexibility if needed.
Reduced velocity couplings like universal joints can perform at large torque and larger degrees of misalignment but they have internal elements that need for being constantly maintained.
If not greasing for lubrication and bearing replacement as well as the angles of misalignment they could get the job done at is constrained as well, as too much will lead to bearing failure.
Our flex coupling can meet the greater torque demands along with the increased versatility while needing no maintenance as you would have to with using universal joints.
A single product multiple uses. Why would you use diverse products if you didnt need to when 1 product will do it all, a no servicing, high speed, high torque, higher angle of misalignment capable versatile coupling.
Three models and counting ¡§C To date we have three models the czep150, czep300 as well as czep500
czep150 is capable of handling 150ft lbs of torque and be utilised at 25??.
czep300 is capable of handling 300 ft lbs of static torque and operate at angles of 25??
czep500 can take care of 500ft lbs of static torque .
We are looking at what the market demands so bigger or smaller we will be adding additional as time goes on.
We have all the splines and keyways you need to fit your equipment.
We want to function with you, so contact us and lets operate collectively to solve your versatile coupling issues today.
Viscous coupling is filled with silicone and is not computer controlled. A series of plates with holes and slots turn inside the silicone fluid. Some plates are attached to the front axle driveshaft and some are attached to the 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 speed, causing a torque transfer in the faster spinning axle for the slower spinning axle. Therefore, slight velocity difference is required for torque transfer.
If the rear wheels and driveshaft are slipping and turning faster than the front, friction concerning the plates increases due on the generated shear within the fluid, slippage is reduced, the rear wheel spin is reduced plus the torque from your input shaft is transferred to the front.
A viscous coupling is usually installed in two ways:
viscous coupling acting instead of the center differential
Viscous Coupling Acting Instead Of the Center Differential
In this case, in normal conditions, all energy is transferred to just one particular axle. One part of the viscous coupling is connected towards the driving axle, another part is linked 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 permits 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 finish is engaged with a slight delay, causing sudden change within 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 delicate to uneven tread wear on front and rear tires. This is why Volvo first reduced the pre-tensioning in 2000 and after that 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 different speeds while cornering. When excessive wheelspin occurs on a single on the axles, viscous coupling locks the differential and equalizes the speeds of both axles. Torque is transferred to wheels that have traction. This can be a full-time all wheel drive system.
Viscous coupling can also be integrated into the rear differential.
