6. as now been added Hand packing of grease in each half of the coupling is recommended After lubrication tighten lube plugs to the specified torque value shown on page 4 Note Spacer limited end float floating shaft couplings and some other styles require each end to be separately lubricated Lubricant capacities for each size and coupling style are given on page 4 Dynamically Balanced Couplings In addition to the previous instructions certain other precautions must be followed to insure coupling dynamic balance at assembly 1 Replace each nut and lock washer on its own bolt as they have been weight balanced as a set The set can be used in any bolt hole 2 Fit the shaft keys precisely to fill the keyway with a tight fit only on the sides Key weight should equal the weight of metal removed from shaft and hub keyways 3 Position each sleeve with it s hub noting any match marks on either the sleeve or hub Keep match marks in line as final assembly is completed 4 Position all other parts such as spacer floating shaft etc properly aligning any match marks 5 Lubricate the coupling Note Use an adapter plate only with half coupling of the same serial number Finish Boring and Keyways Coupling hubs are often furnished with a rough stock bore This rough bore is not necessarily concentric to other hub diameters To prepare for boring set up and indicate the hub as shown by the illustratio
7. eck Angular Alignment For normal hub separation use a feeler gauge at 4 points 90 apart or for best accuracy a dial indicator Position machines to obtain best align ment Normal variation should not ex ceed 001 inches 0 025mm times coupling size Maintain correct hub separation referring to the C dimen sion shown in tabulations on page 4 For greater hub separation than stan dard such as spacer and floating shaft couplings use micrometers or other suitable alignment fixtures to span the separation and measure the four 90 points Offset Alignment Instrument Method Note For maximum coupling life the Instrument Method of coupling alignment is recommended Attach a dial indicator bracket to one hub with dial indicator probe contacting the opposite hub s alignment surface Rotate the hub on which the dial indicator is attached and take readings at 4 points 90 apart The offset TIR should be less than 002 inches times the coupling size For greater hub separation than standard such as spacer or floating shaft couplings use suitable fixtures to span the separation and measure the four 90 points Shim either machine until best possible alignment is obtained Recheck angular alignment and hub separation j j t n i _ The trademarks Kop Flex and Fast s are registered trademarks of Kop Flex Inc The Emerson logo is a trademark and a service mark of Emerson
8. ed without lubricant Expand hub in an oven until the bore is substantially larger than the shaft diameter Straight bored hubs are normally bored for an interference fit of approximately 0 0005 in in of shaft diameter For most values of interference this will require a hub temperature of about 300 150 C Never exceed 600 F 300 C AWARNING To avoid the risk of explosion fire damage to coupling and equipment and or injury to personnel do not use an open flame or oil bath to expand the hub Properly orienting the hubs slip them over the shafts and keys Hub faces are normally mounted flush with shaft end On bolted end ring couplings such as the Fast s cast steel the sleeves are bolted to the end rings after placing the gasket between the flanges Mounting of Tapered Bored Hubs Select the unheated taper bored hub Mount the hub hand tight on its shaft and lightly rap it with a soft mallet to establish the initial line to line fit Draw the hub up an additional distance to obtain the desired interference fit for the connection In some cases the hub may require heating to achieve desired fit The required amount of axial movement is dependent upon the bore diameter and taper angle Install the hub retention means lock nut etc provided with the shaft and securely lock the retainer into place For most installations the hub face will project slightly beyond the shaft end after hub pull up Ch

10. n Bore sizing and recommended fit Finish bore size should be based on the actual shaft dimension measured regardless of whether straight or taper shaft A light interference fit based on a nominal interference of 0005 in per inch of shaft diameter is suggested or refer to published AMA standards Do not exceed an interference fit of 0012 per inch of shaft diameter for Fast s forged steel model B and for the cast steel Alternate fits If other than a light interference fit is desired please consult the published AGMA boring and keyway standards or contact our engineering department for specific recommendations Recommended Set up Method for Boring ne CENTERLINE OF BORE A i z INDICATING INDICATING SURFACE a SURFACE ALIGNMENT DIAMTER ALIGNMENT FACE The alignment diameter of the hub should be chucked in the boring lathe and dial indicated as shown so that run out is as near zero as possible It is essential that the finished bore be concentric with the two indicating surfaces Keyways Keyways should be cut to give a tight fit on the sides and slight clearance over or under the key Keyways should not have sharp corners Refer to published AGMA standards for specific dimensioning of coupling bores and keyways AWARNING Failure to observe safety precautions could cause personal injury
