Please contact Fennerwith all :SELECTION OF THE Couplings :The crowning of the teeth allows the coupling to withstandparallel misalignment upto a maximum of mm andangular misalignment upto a maximum of per gearmesh.

3 The coupling can also absorb axial displacement ofthe shafts upto a maximum of 3 following details are required for selection of thecoupling :1. Type of driven Power absorbed by the driven machine and Peak Speed and Diameter of the connecting shafts andspace available for accommodating the Maximum misalignment to be Surrounding Any other special feature of the for the :A gear Couplings is required to transmit 250 KWfrom an Electric Motor running at 730 rev/min to a PulperMachine. Considering the peak load as 180% of full load,the Motor shaft as 100 mm and the Pulper shaft as 110mm, select a suitable gear ) Service factor : 2 (for heavy duty application)b) Peak load: 180% of full ) Design power : 250 x 180/100 x 2 = 900 KWd) Power to be transmitted at 100 rev/min :900 x 100 / 730 = KWe) coupling size : By referring to the Table, couplingsize FGC 5, has got a rating of 150 KW at 100 rev/minwhich exceeds the required power of Thebore range is 60 mm to 110 mm.

4 Hence, size FGC 5 isFenner Curved Tooth Flexible gear Couplingsare the result of many years of experience in the field ofMechanical Power gear Couplings are distinguished by their mechanicalflexibility and compensation of Angular, Parallel and Axialmisalignments of the connected shafts. They are made forextensive use in Metal Rolling Mills, Paper Machinery, Cranes,Dredgers, Rubber and Plastic Industries, Cement Plants,Conveyors and Elevators, Compressors, Fans and Blowers,Screens and other general gear Couplings basically consist of two hubs, withcrowned external teeth and two outer sleeves with internalspur Hubs and the outer sleeves are manufactured fromcarbon steel and are hardened to the required degree. They aremachined to fine tolerances for proper meshing of the gears aswell as for :The teeth of gear Hubs are crowned and are generated byinvolute system.

5 The amount of crowning and backlash valuesare so chosen as to ensure the best results in torquetransmission, greater flexibility and smooth :'O' RINGS :The internal teeth of the sleeves are generated to ensure correctprofile. The coupling sleeves are joined together with hightensile steel bolts (class IS : 1367) fitted using a gasket inbetween setting of special 'O' Rings at the ends of coupling hubsprevents leakage of lubricants and entry of dust. The 'O' ringscan also withstand high degree of temperature upto 120 COSEAL CARRIERS :POWER RATINGS :SERVICE FACTOR :Seal carriers have been provided for sizes from FGC 11 to FGC19 facilitate inspection and replacement of 'O' rings withoutdisturbing the normal power ratings are given in the Table. For selection ofthe correct size of Couplings , proper service factor depending onthe type of machines and the peak load should be , for medium duty use a service factor of Forheavy duty use a factor of 2 and for extra heavy duty a factor of 3should be special applications please contactFenner with full dimensions are subject to alteration without gear CouplingsFGC 1 FGC 2 FGC 3 FGC 4 FGC 5 FGC 6 FGC 7 FGC 8 FGC 9 FGC 10 FGC 11 FGC 12 FGC 13 FGC 13 AFGC 14 FGC 14 AFGC 15 FGC 16 FGC 16 AFGC 17 FGC 17 AFGC 18 FGC 18 AFGC Gd Valuein Kg M22 Max.

It is recommendedto use grease where the maximum temperature is within 80 Cand for temperature above 80 C, oil should be used.
