High performance curved jaw couplings MIKI PULLEY STARFLEX

General-purpose Coupling of Simple Construction Motive power is transmitted by polyurethane elastomer with the elastic force of rubber. These not only excel in absorbing vibration and shock, they transmit more than double the torque of older jaw couplings. The line-up includes three types of hubs, two types of elements and two types of fit. They can provide the optimum combination for your transmission torque, response, and misalignment. Since you can combine different hubs, they can be used in a wide range of applications. Reduced Counterforce Optimal design of the element shape reduces...

Optimal design by 3D-CAD and FEM analysis The advanced CAE system is utilized in the starting stage of design. Models are designed by using 3DCAD. Shapes and strength design are optimized by using the advanced FEM (finite element method) analysis software. Three types of elements There are three MIKI PULLEY STARFLEX models. Each has a different type of element. Clamping hub material: Aluminum alloy Clamping hub material: Aluminum alloy Clamping hub material: Aluminum alloy Element material: Polyurethane elastomer Shore hardness 97 JIS A Tight fit Element material: Polyurethane elastomer Shore...

MIKI PULLEY STARFLEX Items Checked for Design Purposes ■ Special items to take note of You should note the following to prevent any problems. (1) Always be careful of parallel, angular, and axial misalignment. (2) Always tighten bolts with the specified torque. ■ Precautions for handling ALS models come with three different types of elements and two different types of mounting hubs. Be aware in their handling that their allowable values and points of caution are not the same. (1) Couplings are designed for use within an operating temperature range of −30℃ to 80℃ . (2) Although elements are...

■ Selection procedures ALS models can be selected in one of two ways depending on their mode of use: ordinary use or no-backlash use (exploiting their pre-compressed construction). When considering use of couplings in no-backlash mode, however, be sure that use will be at a torque that is low enough for the nominal torque of the coupling. Note that selection criteria are different for ordinary use and use in no-backlash mode. When considering use of couplings in no-backlash mode, select from among the ALS (ARN) and ALS (AYN) types. ALS (ABN) types cannot be used in no-backlash mode. (1)...
