It consists of either one or two thrust rings with tapered bores and a mating narrow inner ring. By tightening locking screws, the thrust rings are drawn together, compressing the inner ring and applying pressure to the outside of the hub, clamping it to the shaft. Thus the shrink disc is not in the load path. The torque can be transferred by force-locking on the joining surface between the shaft and the hub without an intermediate element.\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fp>\r\n\r\n\u003Ch2 dir=\"ltr\">\u003Cspan style=\"line-height:1.8em\">\u003Cspan style=\"font-size:18px\">\u003Cspan style=\"font-family:Arial,Helvetica,sans-serif\">Shrink Discs are categorized Into\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fh2>\r\n\r\n\u003Cul dir=\"ltr\">\r\n\t\u003Cli>\u003Cspan style=\"line-height:1.8em\">\u003Cspan style=\"font-family:Arial,Helvetica,sans-serif\">\u003Cspan style=\"font-size:18px\">Two-part shrink disc\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fli>\r\n\t\u003Cli>\u003Cspan style=\"line-height:1.8em\">\u003Cspan style=\"font-family:Arial,Helvetica,sans-serif\">\u003Cspan style=\"font-size:18px\">Three-part shrink disc\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fli>\r\n\u003C\u002Ful>\r\n\r\n\u003Ch4>\u003Cbr \u002F>\r\n\u003Cspan style=\"font-size:18px\">\u003Cspan style=\"font-family:Arial,Helvetica,sans-serif\">\u003Cstrong>Two-Part Shrink Disc\u003C\u002Fstrong>\u003C\u002Fspan>\u003C\u002Fspan>\u003C\u002Fh4>\r\n\r\n\u003Cp>\u003Cspan style=\"line-height:1.8em\">\u003Cspan style=\"font-family:Arial,Helvetica,sans-serif\">\u003Cspan style=\"font-size:18px\">Two-part shrink discs are characterized by a flatter cone angle and transfer the necessary torque similarly to a taper interference fit.
