Type of driven machine and operating hours per day. Thoroughly clean all components, paying particular attention to the removal of the protective coating in the bore of the flanges.
Tightening of the screws into the threaded holes in the hub forces the bush into the taper bored components, therebyeffectively contracting the bore of the Taperlock Bush until the equivalent of a ‘shrink fit’ is obtained. Check angular alignment by measuring gap between flanges at several positions around the circumference.
Fenner Tyre couplings can accommodate simultaneous maximum misalignment in all planes fenneer imposing undueloads on adjacent bearings and the excellent shock-absorbing properties of the flexible tyre reduce vibrations and torsionaloscillations.
We also have Fenner tyre coupling price list. When seated, couplimg should be a gap between the ends of the tyre as shown in table 6.
Where Taperlock flanges are used, see separate fitting instructions supplied with the Taper Lock Bushes. Ulubari High School, Guwahati – The flanges are available in either F or H version Taper Lock fitting or bored to size B Genner the addition of a spacer flange, the coupling can be used to accommodate standard distance between shaft ends and facilitate pump maintenance 1.
DAMPINGReduces vibration and torsional oscillations developed in internal combustion engines, the amplitude of which increasesgreatly at critical points in the speed range. Bring shafts into line until dimension M2 is obtained table 5. Taperlock Bushes are suitable for metric as well as imperial shafts. With the addition of a spacer flange, the coupling can be used to accommodate standard distance between shaft ends and facilitate pump maintenance.
The split flexible tyre is then positioned in the flanges and the screws tightened intoplace. This gives the design power which is used as a basis for selecting the coupling.
Fit flanges to the shafts placing the external clamp rings on the shafts. Tighten clamping ring screws alternately and evenly half turn at a time working round each flange untill the required screw torque is achieved. In this event, allow sufficient spacebetween shaft ends for the float and misalignment. They can accommodate parallelmisalignment upto 6 mm, angular misalignment upto 4O and end float upto 8 mm. Diameters of shafts to be connected. Where a key is to be used it should be parallel and side fitting with top clearance.
Dimensions are in millimetresM is the distance between flanges. G is the amount by which clamping screws need to be withdrawn to release tyre. From table 1, the service factor is 1. FennerType spacer couplings are primarily designed for the standard distance between shaft end dimensionsand mm. View in Fullscreen Report. Create your own flipbook.
The range includes couplings with torque capacity upto Nm. For firehazard areas the F. No portion of the Catalogue can be reproduced in any form without authorisation of coulling copyright owner. They can accommodate parallel misalignment upto 6 mm, angular misalignment upto 4O and end float upto 8 mm.
If shaft end float is to occur, locate the shafts at mid- position of end float when checking dimension M2. With the addition of a spacer flange, the coupling can be used to accommodate standard distance between shaft endsand facilitate pump maintenance. F40 21 64 0.
The arrangement of half-threaded holes and longitudinally split tapered bushes ensures maximum grip and fast, easyfitting. Multiply the normal running power by the service factor. Customer Care Centres at: It is desirable to align the coupling as accurately as catalofue, particularly on high speed applications. External M2 Seating Dia. Neoprene rubber compounds are available for use in adverse operating conditions e. The motor shaft is 60 cataloghe diameter and the screen shaft is 55 mm diameter.
The size of coupling is F To ensure proper seating, it may be necessary to strike the outside diameter of the tyre with a small mallet. Locate flanges so that dimension M2 is obtained see paragraph 3. Fort, Mumbai – Road, Miller Ganj, Ludhiana – Note that shaft ends may project beyond the faces of the flanges if required. In this event, allow sufficient space between shaft ends for end float and misalignment.
