Many aspects of Flexible Coupling

The terms such as Vulkan coupling ez spares and flexible coupling has gained enough attention. Typically these kinds of couplings are significant components, which are used in pipe connections and these can be used with pipes of varied materials. As a matter of fact, some the common varieties of pipes, which have couplings installed on them are however the steel, cement, concrete, asbestos plastic, fiber glass etc. Using these components you can in fact join pipes of similar sizes, as well join the pipes of dissimilar sizes.

There is hardly any denying that Flexible Coupling is strategically designed in order to hold on tightly to a pipe connection. These components however feature a clamp along their edges. It is also pertinent to mention here that these are made from stainless steel or other such corrosion resistant materials. Sure the suppliers and manufacturers offer a whole range of varieties of couplings and some of which can be even used with aggressive chemicals.

Types of Couplings

Typically based on the application attributes, these couplings can further be divided into a number of categories – the product range thus includes.

• Flexible diaphragm coupling(vulkan / elpex type)- 0.10 knm to 300 knm nominal torque rating.

• gear couplings – 0.5 knm to 800 knm maximum torque rating.

• pin & bush couplings – 0.04 knm to 1300 knm torque.

• resilient coupling – 0.05 to 123 knm torque.

• torsion shaft – for cement plant 2500 kw low speed side, 7 m. Long.

• solid drive shaft – 500 mm. Diameter, 4.5 m. Long.

• bearing housings – to suit bearing of 700 mm. Outer dia.

Advantages flexible coupling

Get it straight here; there are in fact a number of ways by which a flexible or Vulkan coupling ez spares can prove beneficial. First point – they are cost-effective hence they do not increase your pipeline work budget significantly.

Flexible coupling are also available as a complete unit that's read-to-use. 

No adjustment or cuttings are required. 

Flexible couplings are also very strong but not heavy hence they do not add any extra pressure on pipe connections. 

What’s more? Well, this also goes a long way in ensuring that they can be assembled quickly.

All about Flexible Coupling

The fact has been hallmarked that Vulkan coupling ez spares is in focus and has created ripples in the technological industry. It has been highly appreciated by customers due to its constructional advantages, especially when used in suction dredgers as well as in other maritime applications. 

SBPT stands tall as the name to be relied on for Vulkan coupling ez spares, Flexible Coupling and even beyond. This ISO: 9001-2008 certified Organisation is the specialist in the Design and Manufacture of highly flexible Diaphragm Coupling ( of German concept & Technology ); & Conventional Couplings; since 1994. It is thus pertinent to mention here that SBPT drive systems ensure smooth power transmission that efficiently drive and move machinery, on land and at sea, safely, reliably.

As a matter of fact, sheet advance analysis and manufacturing process have produced increased rating without reducing safety factors. In fact the use of Torsional Vibration Analysis(TVA) package has further allowed for a more precise calculation on the drive system stresses. 

Worry not; the pneumatically operated double cone friction of the Flexible Coupling thus guarantees guided concentricity of the outer part to the inner part. Moreover, the coupling also does not cause any axial load whatsoever, either when it is engaged or disengaged. 

Salient features of the Flexible Coupling:

·        Sizes available to transmit up to 300 kNm of torque.

·        Allows 3 25 degree torsional deflection.

·        Rupture torque 7 9 times of nominal torque.

·        Progressive dynamic torsional stiffness increases with increasing torque.

·        Dampens torsional vibrations.

·        Provides precise systems tuning... several torsional stiffnesses are available for each.

·        Coupling size.

·        Accommodates misalignment.

·        Absorbs shocks and attenuates noise.

·        Rubber-in-shear design serves as a mechanical fuse to protect equipment from.

·        Excessive torque overload.

·        Requires no lubrication / maintenance.

·        Available blind assembly and in single diaphragm designs.

·        Custom built designs available.

The flexible coupling thus stands as the fabric-reinforced rubber coupling with multi- directional flexibility. The use of synthetic fiber guarantees high strength. The coupling is used in applications where two approximately co-axially rotating machines have to be flexibly connected such as diesel engine and electric motor-driven equipment including marine propulsion systems, two-
