ariations and options a ailable Low inertia by suitable hub shape depends on bore size. You can also select various options. Low inertia contribute high speed operation. Three kind of option available. Tapered shaft adaptor Shaft tolerance j /k acceptable Additional keyway milling * Types A / B / C are automatically specified by Miki Pulley according to the combination of bore diameters you select, and cannot be specified by the customer. Integrated element structure of hard rubber and insert Clamp hub and element is assembled by friction force of tightening bolts. Optimal design with the help...

* Types A / B / C are automatically specified by Miki Pulley according to the combination of bore diameters you select, and cannot be specified by the customer. * The d3 dimension is the inner diameter of the element. For d2 dimension exceeding this value, shaft can be inserted only up to LF dimension to the d2 side hub. * The nominal diameter for the clamping bolt M is equal to the quantity minus the nominal diameter of the screw threads, where the quantity is for a hub on one side.* The figures in parentheses ( ) for the SFR-010 are the values when d2 is 08 mm. 004 MIKI PULLEY SERVOFLEX

Standard (option) bore diameter, d1/d2 [mm] and restricted rated torque [N-m] * The shaft tolerance for standard bore diameter is h7 (h6 or g6): designation B. * Shaft tolerances j6/k6: designations J/K are optional, and are only supported for bore diameters marked with O . * Bore diameters marked with • or numbers are supported as the standard bore diameters. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters. * Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component...

Option Tapered shaft supported Allows coupling via a clamp hub when a taper adapter is mounted on the tapered shaft of a servo motor. * Types B / C are automatically specified by Miki Pulley according to the bore diameter you select, and cannot be specified by the customer. * Check the "Standard bore diameters" as rated torque may be restricted by the holding power of the shaft connection component. * Max. rotation speed does not take into account dynamic balance. * Torsional stiffness values given are measured values for the element alone. * The moment of inertia and mass are measured for the...

If you are using a keyed shaft, we can mill a keyway in the clamping hub to your specifications. H9 keyway width standards JS9 keyway width standards * We can also handle standards not listed above. Consult MIKI PULLEY. (Small diameter) Affixing method - t Affixing method KJ: k6 shaft + JS9 keyway — Bore diameter d2 (Large diameter) For nominal bore diameter, select d1 (small diameter) -d2 (large diameter) in that order. If d1=d2 (same diameters), select B, J, and K in that order. B-J-K-BH-BJ-JH-JJ-KH-KJ Standard (option) bore diameter, d1/d2 [mm] and restricted rated torque [N-m] * The shaft...

■ Axial load and amount of displacement ■ Parallel misalignment direction load and 008 MIKI PULLEY SERVOFLEX

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. (5) Insert and mount each shaft far enough in that the paired mounting shaft touches the shaft along the entire length of the clamping hub of the coupling (LF dimension), as shown in the diagram below, and does not interfere with the elements or the other shaft. (1) Couplings are designed for use within an operating temperature from -20‘C to 80‘C. Avoid using it under the environment where water, oil, acid, alkali, ozone,...

BC Tapered shaft supported Option d2 10 ■ Options for keyway milling Options for keyway milling are available on request. However, because they are designed such that torque is tranferred to the friction coupling by the clamp mechanism, care should be taken not to exceed the coupling's permitted torque during use. Note also the following issues: (1) Only ever use keys that are no wider than the keyway. Using keys that are a tight fit could results in damage during mounting or operation. (2) The positional accuracy of keyway milling is visual. If positional accuracy relative to keyway hubs is...

■ Service factor based on load property: K1 (1) Find the torque, Ta, applied to the coupling using the output capacity, P, of the driver and the usage rotation speed, n. ■ Service factor based on operating time: K2 (2) Determine the service factor K from the usage and operating conditions, and find the corrected torque, Td, applied to the coupling. ■ Service factor based on starting/braking frequency: K3 * Please consult MIKI PULLEY for assistance with items marked with [*]. ■ Service factor based on operating temperature: K4 Td [N-m] = Ta [N-m] x K1 x K2 x K3 x K4 (3) The rated torque of the...
