The shrink disc connection is a frictionally engaged shaft-hub connection which serves to fix the hollow shaft or hub on the shaft without backlash. As an alternative to 2-part shrink discs, TAS Schäfer also manufactures 3-part shrink discs as well as Hydraulic Shrink DiscsEspecially the hydraulic shrink discs offer customers an enormous time advantage when clamping. While mechanical shrink discs sometimes require several hours of assembly time, hydraulic shrink discs are clamped within a few minutes with the help of oil pressure. The design is based on a 3-part shrink disc, which consists of a pressure ring with thread, a pressure ring with through holes and a slotted inner ring. 3-part shrink discs have a larger cone angle compared to 2-part shrink discs. This ensures that it is sufficient to loosen the clamping screws to dismantle the shrink disc connection. The use of push-off screws is not necessary here in comparison to 2-piece shrink discs. Due to the way they function, 3-part shrink discs are able to compensate for a larger fitting tolerance during assembly without any significant loss of torque. The fit of the shrink disc can also have a comparatively larger clearance.
However, the general applications of 3-part shrink discs, 2-part shrink discs (displacement-controlled) and 2-part shrink discs (torque-controlled) are mostly identical. The areas of application are, for example (wind power, drive technology, raw material extraction, conveying technology, crushing technology, mixing and process technology as well as on hollow shaft gearboxes of all makes). 3-part shrink discs are also used on shaft couplings ,,TAS WK,, and flange couplings ,,TAS FK,, and ,,TAS FKB,.
