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

Ever-electrical power 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 present extra torsional flexibility in comparison with plain bushes.
These couplings are suited to general engineering application requiring reliable power transmission even underneath conditions of shaft misalignments which are often unavoidable.

Description
Ever-power couplings are used while flexible compensating couplings in every applications requiring a reliable tranny of torque under harsh operating conditions. The conical chairs of the buffer pins facilitate mounting and guarantee maintenance-free procedure. The optimized condition of the barrelled buffers enables straightforward 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 nearly indestructible, the pin and bush style is suitable for applications that involve safeness, such as elevator drives or perhaps fire pumps. The fail-safe aspect of the design enables the coupling to end up being serviced at practical intervals, if the elastomer become damaged.
The elastomer elements reduce 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. These are still available, as well as a contemporary version of the concept: urethane bushings.

Ever-electricity also manufactures many customized variations of the coupling including brake drum and shear pin type couplings.
Damping shaft coupling that can be utilised 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 tested a million times
Due to their torsional versatility, Ever-power couplings can approach critical torsional vibrations away from the operating location of mechanical equipment so that no unwanted effects on the drive train should be expected. Ever-electrical power couplings are made of high-top quality cast iron. The adaptable elements made of synthetic rubber (Buna-N) can be found in different degrees of hardness for most applications. Metal pins and flexible components are designed in order that no use occurs if they are properly fitted.

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