FORM-FLEX METAL DISC FLEXIBLE COUPLINGS - Johnson …

1 FORM-FLEX METAL disc FLEXIBLE COUPLINGSForm- flex COUPLINGS transmit torque while compensating for angular, parallel and axial misalignment betweentwo connected shafts. FLEXIBLE disc COUPLINGS minimize the misalignment forces on the connected Basic flex coupling consists of two hubs, a spacer and two FLEXIBLE discs. The flex disc is an assembly ofthin METAL laminations. In figure shown below, flex disc holes A & C are bolted to the hub and holes B & D arebolted to the spacer. Torque is transmitted in direct tensions from A to B and from C to D through the flex is taken through bending in the link between the bolt TOWER DRIVESForm- flex METAL disc COUPLINGS are widely used in cooling fan drive applications.

2 FORM-FLEX 4 bolt disc COUPLINGS offer more misalignment capacity than any competing METAL disc smaller towers up to about 100 inches DBSE, TB Wood s offers steel and composite spacer tubing options. TrueTube composite torque tubes are lighter than steel and eliminate thermal growth and vibration composite floating shaft COUPLINGS are recommended as a replacement for older multi-section drivelines. Composite COUPLINGS can span up to 240 inches without high maintenance center support PUMP DRIVESForm- flex floating shaft COUPLINGS are a cost- effective, maintenance free alternative to cardan U-joints for vertical pump drivelines. FORM-FLEX COUPLINGS are available with either steel or composite spacer tubing.

3 Composite spacer tubing can reduce total cost by eliminating the need for bearings and support : 708/345-4300 FAX: 708/345-4315 Johnson Power 1 FORM-FLEX METAL disc FLEXIBLE COUPLINGSCOMPLETE PRODUCT OFFERING-TORQUE CAPACITY TO 3175 HP/100 RPM-CLOSE COUPLE, SPACER AND FLOATING SHAFT DESIGNSHIGH STRENGTHSTEEL FASTENERS-NO MOVING PARTS-ZERO BACKLASHOVER 30 YEARSEXPERIENCE INMETAL DISCCOUPLINGSAPPLICATIONS-PUMPS-FANS AND BLOWERS-COMPRESSORS-FOOD PROCESSING-PRINTING-MACHINE TOOLSALL METAL CONSTRUCTION-WIDE TEMPERATURE RANGE-AVAILABLE IN CARBON OR STAINLESS STEEL-COMPOSITE MATERIALS NOW AVAILABLEHIGH STRENGTHSTAINLESS STEELFLEX DISCS-HIGH TORSIONAL STIFFNESS-NO LUBRICATION REQUIRED TYPICAL APPLICATIONSPHONE: 708/345-4300 FAX.
