Back to TopRotation Transmission ProductsFLEXIBLE COUPLINGSWhen connecting two shafts, to perform a complete centring is very difficult work.It’s also difficult to maintain the condition due to a deflection of shaft caused bymachine operation, thermal expansion of shaft, bearing block strain after a longtermuse or bearing wear. However, theses problems can be solved by choosingthe appropriate flexible coupling in accordance with the intended use. As well asgeneral-purpose motors, a wide range of products corresponding from servomotors for ultra precision controls to engines that generate a large vibration andimpact are available.SERVO FLEX,is a metal disk type coupling with high torsional rigidity. It is rigid in the torsionaldirection, and is flexible in the bending, asymmetrical and axial directions. Theplate spring is made by a latest finite element analysis method to achieve anidealized shape. The SFC model is a compact and lightweight model with highstrengthaluminium alloy used for the hub material. For the SFS model, carbonsteel is used for the body material. The SFM and SFF model developed for use inmain shaft and feed application shaft are also available.CatalogueLinkCAD DataLinkSTARFLEX,has a simple construction of two hubs with one element inside. There are 2 kindsof elements that are different in hardness, selectable according to misalignmentand torque response. The material of the element is a Polyurethane Elastomer,that realized 2 times of torque comparing with our earlier jaw coupling type. Nobacklash is possible due to the pre-pressured design of element and hub. The hubis made of aluminium alloy, which has two types of connection, clamp type or keytype. Starflex passed our Green design criteria and adopts to RoHS instructive.CatalogueLinkCAD DataLinkPage 2© DKSH

Back to TopPositioning Control ProductsControllersIntroduction of control systems is gaining for automated machinery in variousfields. Especially, position control systems are used for all kinds of automatedmachinery. We offer various controllers suitable for fixed position-to-positioncontrol, synchronous (follow-up) control and biaxial interpolation control. Also, acontroller that controls a powder brake voltage to obtain a stable tension controlis available. Troublesome task in the process of system construction is reducedby our easy-to-operate controllers with advanced controls.Servo pulse ControllerA servo pulse controller is used to control the operation when using a servo orstepping motor for the drive member. Miki Pulley's controllers are designed forperformance improvement according to application. Any actuator compatible withpulse input is connectable. The SPC-007 model for roll feed control, SPC-PULCON for X-Y control and SPC-SYNCHRO for synchronous (follow-up) controlare available.CatalogueLinkCAD DataLinkControl shaft numbers: 1 to 2 shaftsTension controllerWhen rolling up a film, fabric or thread, the diameter differs between beginning andend of take-up, and the tension added to the material constantly varies. If stretchmaterial is not taken up with constant tension, it leads to a product failure. Atension controller changes the torque on the take-up side to control the tension tobe constant regardless of diameter. As a control method, there are a "close droopmethod" that detects an actual tension by a tension sensor to control torque and"open loop method" that detects integrated thickness to control torque by the resultof calculation.CatalogueLinkCAD DataLinkPage 6© DKSH
