What is pin bush coupling?
Industrial Pin Bush Coupling
The function of a flexible coupling is to transmit torque from on shaft to another in cases where limited mis alignment might occur and also to absorb shock loads.
We are among the prominent companies engaged in providing Pinbush Coupling that has highly developed rubber compounds for use in bushes to absorb shock, tensional vibrations and slight misalignments. These couplings will be flexible in type and tend to be of the cushioned drive type that is used for transmitting the torque through maximum tensile metal bolts to the machine input. Moreover, they are simple and small in construction that makes these with the capacity of transmitting large torques at optimum speeds. These kind of couplings generally permit drive in either path and require neither lubrication, nor adjustment after fitting.

Ever-ability pin and bush coupling
Ever-power couplings contain a set of resilient BARREL Shaped bushes with pins & nuts and two flanged hubs of graded cast iron.
The special BARREL shaped bushes permit the MISALIGNMENT EVERYWHERE and present extra torsional flexibility in comparison with plain bushes.
These couplings are suitable for general engineering application requiring reliable power tranny even within conditions of shaft misalignments which are often unavoidable.

Description
Ever-power couplings are being used as flexible compensating couplings in every applications requiring a trusted transmission of torque under harsh operating conditions. The conical chairs of the buffer pins facilitate mounting and guarantee maintenance-free procedure. The optimized shape of the barrelled buffers allows simple plug-in assembly and low circumferential backlash. Various type variants are offered, e. g. with brake disk, axial play limiting system, or brake engine couplings.

Pin & Bush Couplings
Simple and virtually indestructible, the pin and bush design and style is well suited for applications that involve safety, such as for example elevator drives or fire pumps. The fail-safe aspect of the design permits the coupling to become serviced at practical intervals, should the elastomer become damaged.
The elastomer elements lessen vibration and dampen impact loads, and accommodate misalignment up to 0.5 degrees. The original bushing can be a neoprene elastomer with a graphite impregnated bronze sleeve. These are still available, in addition to a contemporary version of the concept: urethane bushings.

Ever-power also manufactures many custom variations of the coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be used universally to pay for shaft misalignment
Nominal torque range from TKN = 19 Nm up to 62,000 Nm with 23 sizes
Temperature range: from -50 °C to +100 °C

Robust and confirmed a million times
Due to their torsional overall flexibility, Ever-power couplings can approach critical torsional vibrations from the operating spot of mechanical equipment in such a way that no negative effects on the drive train should be expected. Ever-ability couplings are constructed of high-top quality cast iron. The adaptable elements made of synthetic rubber (Buna-N) are available in different examples of hardness for many applications. Metallic pins and flexible components are designed in order that no don occurs if they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the perfect operation of your system. The flexible factors of the Ever-electrical power coupling are at the mercy of compression. If the flexible elements are irreparably destroyed, the hub parts touch metal. This “emergency procedure capability” is required, e.g., regarding fire pump drives.
