COUPLINGS INTRODUCTION Couplings Our range of couplings have been proven to be some of the most reliable, durable and effective couplings in the marketplace. These qualities have been achieved by our attention to detail in design, manufacturing capabilities and application expertise. This ensures our coupling range is capable of providing solutions for a wide and varied range of applications and installations. Elign Gear Couplings The Elign range of gear couplings not only connect two rotating shafts, but also accommodate the inevitable misalignment that can occur in installations. The Elign...

COUPLINGS SELECTION Mechanical Ratings and Service Factor The mechanical ratings are a measure of the couplings capacity in terms of life and strength, they assume 10 hours/day operation under uniform loading conditions and allow for a 100% momentary overload at starting or braking The mechanical Service Factor (fm) is selected dependant on the type of prime mover, the classification of the driven load, and duration of operation i) Obtain the driven load classification type from the table Load Classification by Application Determine the mechanical service factor from the table below: Prime Mover...

COUPLINGS NOTES

GEAR TYPE COUPLINGS

ELIGN GEAR COUPLINGS Features of ELIGN Gear Coupling The ELIGN Gear Couplings consist of hubs with multi crowned teeth at the flank, tip and chamfer. The ELIGN hub teeth are manufactured using the latest state of the art CNC machines, and are manufactured from quality forged carbon steel, and are subjected to a number of quality checks and tests. The superior design of the multi- crowned tooth profile enables the ELIGN gear coupling to operate satisfactorily under all operating conditions with increased reliability and durability. The multi- crowned teeth are tolerant to misalignment whilst improving...

ELIGN GEAR COUPLINGS Gear Couplings Gear Coupling are used to join two rotating shafts for efficient transmission of mechanical power. Although the shafts can be accurately aligned at the time of installation, it is likely that during the operation the alignment may get disturbed due to settling of the foundation, thermal expansion, shaft deflection, wearing out of other parts, improper maintenance or many other reasons. Due to unavoidable misalignment occurring during operation a Gear Coupling provides An ideal solution to compensate or minimise the effect of misalignment. Gear Couplings are...

ELIGN GEAR COUPLINGS Lifting Hole The hubs of larger size couplings are supplied with lifting holes, as indicated on the dimension sheets. Lubrication Each coupling half is provided with a grease nipple / plug from where grease can be filled directly. WARNING: Grease should be applied Protection All components of ELIGN gear couplings have a rust preventative coating. Coupling Bores Hubs are bored to suit the customers shaft size (see dimension tables for the minimum / maximum allowable bore) standard metric keyways conform to DIN-6885, PART-1 (unless otherwise specified) Couplings can also be...
