Optimal design thanks to 3D-CAD and FEM analysis
The latest CAE system was used from the initial stages of design. These models were designed using 3D-CAD. Shape and hardness was designed using the support of the latest finite element method (FEM) analysis software for optimal designs.
High transmission torque achieved and mounting error reaction force reduced by optimal design of element shape
They achieve more than double the transmission torque of older jaw couplings for the same outer diameter thanks to improved torque transmission component shapes and rigorous selection of materials.Couplings that have no backlash (ALS Y and R type) and are gentle on the partner shaft have been achieved by installing an undercut on the inner diameter side and reducing the mounting error reaction force.
Can be freely combined
Select from among three types of hubs: pilot-bore types that can be freely drilled with bores, key/set screw types, and clamp types.Key/set screw types and clamp types can also be combined.
ALS-AYN (Clamp Type)
[Specifications]

*Check the Standard Bore Diameter and Rated Transmission Torque list as there maybe limitations on the nominal and max. torque cased by the holding power of the coupling shaft section.
*Axial displacement is not allowed in the negative direction. * Max. rotation speed does not take into account dynamic balance.
*Stiffness values given are from measurements taken at 20℃.
*The moment of inertia and mass are measured for the maximum bore diameter.
[Dimensions]

*The φDB value is measured assuming that the head of the clamping bolt is larger than the external diameter of the hub.
*The nominal diameter for the clamping bolt M is equal to the quantity - the nominal diameter of the screw threads, where the quantity is for a hub on one side. The values in ( ) in the above table are for ALS-040 hole diameters φ22 and φ24, φDB : 45.1 mm, B : 6.5 mm, M : 1-M5, clamping bolt tightening torque : 7 N・m.
[Standard bore diameter and rated transmission torque]

*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 φ35 (HA), the tolerance is .
*Bore diameters between the minimum and maximums shown in the dimensions table are compatible, but bore diameters other than those shown in the above table require other arrangements. Contact Miki Pulley for details.
