MIKI PULLEY

MIKI PULLEY

Element hardness 97JIS A used, designed to use preliminary compression with no backlash. Supports a wide range of applications, from simple servo to general purpose motor with high torque.

[Features]
· Polyurethane elastomer used for element. So, the transmission torque is more than twice that of conventional jaw coupling.
· Design to distribute pre-compression, and so can be used with no backlash. (ALS-Y/R type)
· Power transmission through polyurethane elastomer with rubber elastic force. It has excellent vibration and impact absorption.

Jaw Couplings MIKI PULLEY STARFLEX

Available Models

There are three MIKI PULLEY STARFLEX models. Each has a different type of element.
 
ALS(R) ALS(Y) ALS(B) 
These are JIS A tight-fit, high-torque,
high response models that have
a shore hardness of 97.
 		 These are JIS A tight-fit models that have a
shore hardness of 90 and are equipped with
a good balance of torque transmission
performance, flexibility, and responsiveness.		 These are JIS A loose-fit, high-torque, flexible
models that have a shore hardness of 97.

* The øDB 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 minus the nominal diameter of the screw threads, where the quantity is for a hub on one side.

* 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 class. However, for a bore diameter of ø35, the shaft tolerance is +0.010  -0.025.
* 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.
