Flexible Geared Couplings

Listing ID #898320

We are offering Flexible Geared Couplings in different specifications. Flexible Geared Couplings are used to connect two shafts together for transmitting power. With the careful selection and installation of our Flexible Geared Couplings, savings can be made in terms of reduced maintenance costs and downtime. Our Flexible Geared Couplings are appreciated by the customers for their dimensional accuracy, excellent performance, interchangeability and pocket friendly price.

Applications :
Gear coupling with highest torque capacities than any other flexible coupling, generally used for applications like Conveyors, Cement Mills, EDT Cranes, Elevator Drives, Ball & Bowl Mill Drives, Industrial Fans, Air Compressors, Rolling Mill Drives and Mining Machinery Proper Size of the coupling from rating and dimensional table can be selected after adding proper safety factor to max. load application (refer S.F.table).
A Gear coupling is a mechanical device for transmitting torque between two shafts. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third part called Pin. The gear teeth in a gear coupling have minimum backlash to allow for angular misalignment. The excess backlash can contribute to vibration.

Salient Features :

• Less Backlash
• Compact Assembly
• Larger Bore Capacities
• High Power to Weight Ratio
• Accommodates Angular, Parallel & Axial Misalignment
• Generally used upto 120°C. Can be used for higher temperatures by using proper grade of grease or oil

Selection of the Couplings :
The following details are required for selection of the coupling :

• Type of driven machine
• Power absorbed by the driven machine and Peak load
• Speed and diameter of the connecting shaft

Example : A gear couplings is required to transmit 250 'rWVfrom an Electric Motor running at 730 rev/ruin to a Pulper Machine. Considering the peak load as 180% of full load, the Motor shaft as 100 mm and the Pulper shaft as 110 mm, select a suitable gear coupling.

Service factor : 2 (for heavy application)

• Peak load : 180% of full load
• Design power : 250 x 180/100 x 2 = 900 KW
• Power to be transmitted at 100 rev/min : 900 x 100/730 = 123.3 KW
• Coupling size : By referring to the Table, coupling size KFG has got a rating of 150 KW at 100 rev/min which exceeds the required power of 123.3 KW. The bore range is 60 mm to 110 mm. Hence, size KFG is selected for the application.
