PIN coupling

What’s 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 may occur and also to absorb shock loads.
We are among the prominent organizations engaged in providing Pinbush Coupling that has highly developed rubber compounds for use in bushes to soak up shock, tensional vibrations and small misalignments. These couplings will be flexible in type and are generally of the cushioned travel type that is utilized for transmitting the torque through the best tensile metal bolts to the machine input. Moreover, these are simple and compact in construction that makes these capable of transmitting large torques at optimum speeds. These kind of couplings generally permit drive in either way and need neither lubrication, nor adjustment after fitting.

Ever-ability pin and bush coupling
Ever-power couplings consist of 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 give extra torsional flexibility as compared to plain bushes.
These couplings are ideal for basic engineering application requiring reliable power transmission even below conditions of shaft misalignments which are generally unavoidable.

Ever-power couplings are being used because flexible compensating couplings in all applications requiring a trusted transmission of torque under harsh operating circumstances. The conical seats of the buffer pins facilitate installation and guarantee maintenance-free operation. The optimized form of the barrelled buffers allows simple plug-in assembly and low circumferential backlash. Many type variants are offered, e. g. with brake disk, axial play limiting unit, or brake motor couplings.

Pin & Bush Couplings
Simple and practically indestructible, the pin and bush design is perfect for applications that involve security, such as elevator drives or fire pumps. The fail-safe aspect of the design allows the coupling to end up being serviced at convenient intervals, should the elastomer become damaged.
The elastomer elements decrease vibration and dampen impact loads, and also accommodate misalignment up to 0.5 degrees. The original bushing is a neoprene elastomer with a graphite impregnated bronze sleeve. They are still available, as well as a contemporary version of the concept: urethane bushings.

Ever-ability also manufactures many custom variations of this coupling including brake drum and shear pin type couplings.
Damping shaft coupling that works extremely well universally to compensate 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
Because of their torsional versatility, Ever-power couplings can maneuver critical torsional vibrations away from the operating area of mechanical equipment so that no unwanted effects on the drive train should be expected. Ever-vitality couplings are constructed with high-quality cast iron. The versatile elements manufactured from synthetic rubber (Buna-N) are available in different degrees of hardness for many applications. Metallic pins and flexible components are designed in order that no have on occurs if they are properly fitted.

Did you know?
Original Ever-power elastomers ensure the perfect operation of one’s body. The flexible components of the Ever-electric power coupling are subject to compression. If the versatile elements are irreparably harmed, the hub parts come into contact with metal. This “emergency operation capability” is necessary, e.g., regarding fire pump drives.
