STARFLEXJaw Couplings with a Simplified StructurePower is transferred by the polyurethane elastomer with the elastic force of rubber, which has superior vibration and shockabsorbability. High torque transmission that is more than double that of conventional mikipulley’s jaw couplings is achievedby pursuing the optimal shape.Although it is a high transmission torque, misalignment reaction force has been signifi cantly reduced by undercuts of theinner diameter side.While use with no backlash is available by a design allowing preliminary compression (ALS-R · ALS-Y), the couplings canbe used for the target shaft or bearing with damage-free.Also, the couplings are compliant with the EU Restriction of Hazardous Substances Directive, “RoHS Direcctive,” thatprohibits six hazardous materials such as mercury, lead, and others.Optimal design by 3D-CAD and FEM analysisThe advanced CAE system is utilized in the starting stage of design. Models are designed by using 3D-CAD. Shapesand strength design are optimized by using the advanced fi nite element method (FEM) analysis software.THRUSTTORQUETHRUSTTORQUEWith optimally designed element shapes, higher torque transmissionand reduced misalignment reaction force are realized.High torque transmission that is more than double that of mikipulley’s conventional jaw couplings with respect to theoutside diameter is achieved by modifying the shape of the torque transmitting part and rigorously selecting materials.Moreover, ALS-B type with uncompressed loose fi t shape can increase the permissible misalignment by modifying thetorque transmission part to crowning shape.In addition, no backlash couplings that are easy on the target shafts are realized by placing undercuts to the innerdiameter side to reduce the misalignment reduction force.Torquetransmitting partStraight shapeTorquetransmitting partCircular shapeConvex shape(Crowning shape)UndercutConventional elementSTAR FLEX element with a circular shapetorque transmission partThe torque transmission part of ALS-Btype element has a crowning shapeUndercut common to all models72www.feyc.es
