COUPLINGS

• Dismounting(1) Confi rm if any torque or axial direction load does not act onthe coupling. Torque may be applied to the coupling when asafety break control system is activated. Make sure no torqueis applied to the coupling.(2) Loosen all the bolts pressurizing the sleeve. For the SFMmodel, loosen the bolts about 2mm from the sleeve edge. Forthe SFF model, loosen the bolts about 2mm from the bearingsurface.SFF modelAbout 2mmSFM modelAbout 2mm(3) Remove three pressure bolts loosened in (2) (two bolts forthe sizes 070 and 080 of SFF model) and insert them into thescrew bores for dismounting located on the sleeve. Tightenthem alternately little by little. Locking of the fl ange hub andshaft will be releasedFor the SFM model, hexagon socket head cap screws areused as its pressure bolt. Therefore, a space for L wrenchmust be considered in the design phase. If there is not aspace in the axial direction, insert a flat-head screwdriver intothe A part and tap in a direction perpendicular to the shaft, oruse the principle of leverage to release locking. At this time,take extra care not to damage the coupling or pressure bolt.SFF modelPart ASFM modelPart ASERVO FLEXSFF · SFMIn the tapered shaft fastening method that tightens thepressure bolts from the axial direction, the sleeve has a selflockingmechanism so that loosening the bolts does notrelease locking of the fl ange hub and shaft. (In some cases,locking force could be released by just loosening the pressurebolts.) Therefore, a space for inserting a dismounting screwmust be considered in the coupling design phase.SFF modelXSFM modelXX28X-XX34 23*39 *34X-XNote) In the case of SFM-140, apply dimension with *.The latest CAD data can be downloaded from our website. http://www.mikipulley.co.jp/COUPLING_E_42_55new.indd 55CADAtención al Cliente - 902 208 608The CAD mark indicates that CAD data is available by CD-ROM.The CAD fi le No. represents the fi le name in the CD-ROM.559/15/10 4:26 PM
