Coupling description The POLY coupling is a torsionally flexible, shear shaft coupling forgeneral machinery. It is assembled by axially pluging the hubs intoeach other and has excellent dampening characteristics. Its uniquefeatures are the flexible elastomeric elements that are located in bothcoupling halves. The POLY advantage – A much greater number of flexible elements andthus a larger effective mass of the elastomer to accept vibration and todissipate the heat caused by torsional vibrations when compared tosimilar competitive couplings with elements only in one half. Function 02-poly-norm_revolex-kx_poly_de The coupling consists of 2 hubs with fingers that are separatedby elastomeric elements which are assembled by axial blind plug-in toeach other. Elastomer elements are placed into the slots of bothcoupling hubs. Torque is transmitted in a compact design. Shaftmisalignments, vibrations and shock loads are effectively absorbed bythe POLY coupling. The coupling is maintenance-free and used in general machinery, thepump industry and in compressors. The Poly coupling handles torqueranges of up to 65,000 Nm and is stocked in 21 different sizes and 4designs for immediate availability. In addition to our standard couplingmodels, a variety of flange, drop out center and spacer options areavailable. Variation of components 2-poly-norm_revolex-kx_poly_de_1 The coupling can be adapted to many applications due to the manyoptions that are possible with the building block arrangement. The POLYcomponents of a given model can be mixed and matched with each other toobtain different shaft distances using the same basic component.   Explosion protection use ex-log_2 POLY couplings are suitable for the use in drives in hazardousareas. The couplings are certified according to EC Standard 94/9/EC(ATEX 95) and belong to category 2G/2D, are confirmed and thus suitablefor the use in hazardous areas of zone 1, 2, 21 and 22.
