Starflex ALS AN datasheets

Product catalog summary

Specifications:
The datasheet outlines specifications for STARFLEX ALS jaw couplings, covering models ALS-030B to ALS-105B. Key parameters include nominal and maximum torque, misalignment tolerances (parallel, angular, axial), maximum rotation speed, static torsional stiffness, radial stiffness, moment of inertia, and mass. Axial displacement is prohibited in the negative direction, and higher RPMs are achievable with balancing. Stiffness values are measured at 20°C, with moment of inertia and mass specified for the maximum bore diameter.

Dimensions:
Dimensions for each model are detailed, including minimum and maximum bore diameters, overall dimensions, and tightening torque. It is noted that the clamping bolt head is larger than the hub's external diameter.

Standard Bore Diameter and Rated Transmission Torque:
Standard bore diameters and corresponding rated transmission torque values are listed for each model. Bore diameters are standard and limited by the shaft connection component's holding power. Recommended processing tolerance for paired mounting shafts is h7, with specific tolerances for certain diameters.

Ordering Information:
Instructions for placing an order include size, element type, and bore diameter specifications. Keyway standards for H9 and JS9 are provided, with detailed dimensions for each nominal bore diameter.

Additional Notes:
Contact information for Miki Pulley in Europe is included, with a note that they can accommodate standards not listed in the document.

Procedures and Recommendations:
Check the standard bore diameter and rated transmission torque list for limitations on nominal and max torque due to the holding power of the coupling shaft section. Axial displacement is not allowed in the negative direction. Higher RPMs are possible with balancing. Stiffness values are measured at 20°C. The moment of inertia and mass are specified for the maximum bore diameter.

Dimensions and Keyway Standards:
Detailed dimensions for each model are provided, specifying parameters such as diameter, length, and tightening torque. Keyway standards, including nominal bore diameter, keyway width, and height, are outlined with specific tolerances for different shaft diameters.

Material and Element Type:
The elements are made of polyurethane elastomer with a hardness of 90 JIS A, suitable for tight-fit applications. Dimensions for the spider elements of each model are listed.

Contact details for Miki Pulley in Europe are provided for further inquiries and orders.

MIKI PULLEY Standard bore diameter d1, d2 [mm] and rated transmission torque [N-m] • Bore diameters whose fields contain numbers are supported as the standard bore diameters. • Bore diameters whose fields contain numbers are restricted in their rated transmission torque by the holding power of the shaft connection component. The numbers indicate the rated transmission torque value [N-m]. • The recommended processing tolerance for paired mounting shafts is the h7 (HA) class. However, for a shaft diameter of 035, the tolerance is Z 0010. • Bore diameters between the minimum and maximums shown in...
