LOCKING SHAFT TO CONTROL KNOB

The shaft is coupled to the knob by means of a shaft with keyway. Caution!

For technical reasons the keyway is very small.

See attached diagram for bore/shaft dimensions.

BORE

The shaft bore is executed with an H7 tolerance.

It does not require a side bore for fixing.

he diameter of the bore is fixed and cannot be varied.

SPECIAL REQUEST

CHARACTERISTICS

The main feature of this product is the possibility of making a continuous adjustment of the machine shaft to which it is attached and of maintaining the selected position.

The special clutch, the heart of the mechanism, permits very small continuous movements and therefore the possibility of making precision adjustments in both directions.

Once the desired position is reached, the clutch prevents any rotation caused by small vibrations or movements arriving from the shaft.

The use of this system prevents accidental or involuntary rotation of the shaft.

LIMITATIONS

The clutch is not sufficient to block any movements caused by strong vibrations.

Moreover the control knob is not capable of withstanding the weight of the shaft, therefore it does not replace the normal support systems ( bearings, flanges, etc...).

The control knob cannot be used with motor drive systems.

Reduced depth keyway executed in compliance with a DIN 6885-2.
