Coupling fall into two most important categories: Materials Flexing and Mechanical Flexing. The material flexible varieties acquire their versatility from stretching or compressing a resilient material, for instance rubber, or from your flexing of thin metallic discs or grid. Material flexing couplings will not 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 demand lubrication.

Material Flexing Couplings
Materials flexing couplings typically do not demand lubrication and operate in shear or compression and therefore are in a position to accept angular, parallel and axial misalignment.

Examples of materials flexing couplings are jaw, sleeve, tire, disc, grid and diaphragm couplings.
– Jaw Couplings
Blog site Written content Picture
The jaw coupling is really a material flexing coupling that transmits torque thru compression of an elastomeric spider insert placed among two intermeshing jaws.
Flex component is commonly made of NBR, polyurethane, Hytrel or Bronze
Accommodates misalignment
Transmits torque
Utilized for torsional dampening (vibration)
Very low torque, general purpose applications
– Sleeve Coupling
Website Material Picture
The sleeve coupling transmits reduced to medium torque concerning connected products in shear by an elastomeric insert with male splines that mate with female hub splines. The insert material is normally EPDM, Neoprene or Hytrel plus the insert could be a 1 or two piece layout.
Reasonable misalignment
Torsional dampening (vibration)
End float with slight axial clearance
Minimal to medium torque, general purpose applications
– Tire Coupling
Site Information Picture
These couplings possess a rubber or polyurethane component connected to two hubs. The rubber component transmits torque in shear.
Minimizes transmission of shock loads or vibration.
Substantial misalignment capacity
Effortless assembly w/o moving hubs or connected tools
Moderate to substantial pace operation
Broad choice of torque capability
– Disc Coupling
Blog Material Picture
The disc coupling?¡¥s principle of operation has the torque transmitted by flexing disc aspects. It operates as a result of tension and compression of chorded segments on a popular bolt circle bolted alternately concerning the drive and driven side. These couplings are generally 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 required to accommodate parallel misalignment.
? Allows angular parallel and axial misalignment
? Can be a correct restricted finish float layout
? A zero backlash style
? Higher pace rating and stability
– Diaphragm Coupling
Website Material Picture
Diaphragm couplings use just one or even a series of plates or diaphragms for that flexible members. It transmits torque from the outside diameter of the flexible plate to your within diameter, across the spool or spacer piece, after which from within to outdoors diameter. The deflection on the outer diameter relative towards the inner diameter is what happens once the diaphragm is subject to misalignment. For instance, axial displacement attempts stretch the diaphragm which effects in a blend of elongations and bending from the diaphragm profile.
? Makes it possible for angular, parallel and substantial axial misalignments
? Utilized in large torque, higher velocity applications
Mechanical Flexing Couplings
The mechanical flexing couplings accept misalignment from rocking, rolling or sliding of metal surfaces. All metal mechanical flexing couplings demand lubrication.
Examples of mechanical flexing couplings are gear, grid and roller chain couplings.
– Gear Couplings
Weblog Written content Image
Gear couplings transmit the highest amount of torque and the highest quantity of torque while in the smallest diameter of any versatile coupling.

Each coupling consists of 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 from the rocking and sliding of your crowned gear teeth against the mating sleeve teeth. Parallel misalignment is accommodated by owning two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication based on the application. They’re delicate to lubrication failures but when thoroughly put in and maintained, these couplings possess a services existence of three to 5 many years and in some cases they will final for many years.
– Grid Couplings
Blog site Content material Picture
Grid couplings consist of 2 radially slotted hubs that mesh which has a serpentine strip of spring steel the grid delivers torsional damping and flexibility of an elastomer however the power of steel. Grid couplings transmit torque and accommodate angular, parallel and axial misalignment from one hub towards the other as a result of the rocking and sliding of the tapered grid from the mating hub slots. The grid cross segment is usually tapered for far better hub speak to and a lot easier assembly. As there is certainly motion amongst contacting hub and grid metal components, lubrication is required.
– Roller Chain Coupling
Web site Written content Picture
Roller Chain type couplings consist of two radially sprocketed hubs that engage a strand of double pitch roller chain. Chain couplings are employed for very low to moderate torque and pace applications. The meshing in the sprocket teeth and chain transmits torque along with the connected clearances accommodate angular, parallel and axial misalignment.

Chain couplings call for periodic lubrication depending on the application. The lubrication is normally brushed onto the chain plus a cover is applied to aid maintain the lubrication about the coupling.

Mechanical Electrical power Transmission ¡§C Shaft Coupling replacement technology.
Replaces Spicer, Lovejoy, Beam, Bellows and Jaw type shaft couplings
EP Coupling will be the hottest in shaft coupling style and design, beam, bellows and jaw couplings all do the job at large velocity but lower angle of misalignment.
On the other end universal joints are able to handle larger quantities of misalignment but at reduced speeds and continuous maintenance.
EP Coupling as a hybrid flexible coupling can do both.
Improving on current coupling engineering we deliver numerous distinctive versions which lets a 0 to 25?? operational angle of usage
No inner elements ¡§C No bearings to be frequently lubricated and replace , this saves you money and time.
One particular Piece design and style usually means no broken yokes or hubs.
High speed- Runs at up to 7000 RPM
Torsionally rigid at minimal angles of misalignment
Scalable ¡§C the EP unit could be scaled up or right down to suit individual buyer demands.?
Customizable ¡§C Have a precise form/function the spring/ball settings can be altered to match most applications.
Distinct shaft forms or sizes, we do AGMA/ANSI, SAE, & DIN bore/keyway and spline bore?¡¥s.
Being made from two counter wound springs means it absorbs shock force without damage
Spring design and style makes it possible for greater angle of usage without damaging elements?
ISO9001 2007 manufactured
The patented EP layout will allow for larger angle of utilization without deformation using the torque transfer seen with Universal Joints, giving the performance of a Universal joint without the continual upkeep.
So how does it operate? The design is quite simple, the sets of springs are counterwound so one tightens while the other loosens and visa versa.
This will allow the coupling to work in both forward and reverse.
Its simplicity doesn?¡¥t end there, the only thing inside the center on the coupling is actually a single ball bearing this will allow the coupling to pivot allowing for maximum flexibility, this usually means no bearings.
Bearings are a consistent upkeep issue, they cannot run in harsh environments like water, mud, sand, dust and dirt as any intrusion by any of those components leads to rapid failure.
So no bearings suggests no continuous upkeep or worse substitute.
A single piece 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 flexible coupling is powered by the springs, but because it can be a pair of springs it effectively is often a metal bar, add the ball bearing it turns into a versatile metal bar.
So this signifies extra torque and still have the flex that would destroy a standard universal or continual velocity joint.
Substantial speed/low speed ¡§C Now flex coupling technological innovation is split into 2 major areas, higher velocity, minimal torque, small angle of misalignment and decrease pace, increased torque, increased angle of misalignment.
Unique couplings applications, same product ¡§C Flexible/High speed 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 volume of torque these flex couplings can take care of is quite small.
EP?¡¥s flexible coupling remains torsionally rigid at reduce angles at substantial velocity, with far far more torque than say a standard beam coupling, with all the added flexibility if required.
Lower pace couplings like universal joints can operate at large torque and larger degrees of misalignment but they have inner elements that need to become continually maintained.
If not greasing for lubrication and bearing substitute as well as angles of misalignment they’re able to perform at is constrained as well, as too much will lead to bearing failure.
Our flex coupling can meet the larger torque demands along with the increased flexibility while needing no servicing as you would have to with using universal joints.
1 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, large torque, greater angle of misalignment capable versatile coupling.
Three models and counting ¡§C To date we have three models the czep150, czep300 along with the 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 deal with 500ft lbs of static torque .
We are looking at what the market demands so bigger or smaller we will be adding a lot more as time goes on.
We have all the splines and keyways you need to match your equipment.
We want to function with you, so get hold of us and lets function collectively 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 to your front axle driveshaft and some are attached on 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 from the plates with differentiating velocity, causing a torque transfer from your faster spinning axle to 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 in between the plates increases due to the generated shear inside the fluid, slippage is reduced, the rear wheel spin is reduced along with the torque from your input shaft is transferred to the front.
A viscous coupling can be installed in two ways:
viscous coupling acting instead of the center differential
Viscous Coupling Acting Instead Of a Center Differential
In this case, in normal conditions, all electrical power is transferred to just 1 axle. One particular part of the viscous coupling is connected for the driving axle, another part is connected to your driven axle. When driving wheels slip, viscous coupling locks and torque is transferred to your other axle. This is an automatic all wheel drive system.
The disadvantage of the viscous coupling is that it engages too slowly and lets 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 by using a slight delay, causing sudden change while in 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 then 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 one particular of your axles, viscous coupling locks the differential and equalizes the speeds of the two axles. Torque is transferred to wheels that have traction. This is really a full-time all wheel drive system.
Viscous coupling can also be integrated into the rear differential.
