Velocity Control of Spring Loaded Mechanisms
Springs provide motive force to a mass at the expense of continuously increasing velocity. Airpot damping develops an opposing force to limit this velocity to a desired value.
In laser equipment (as shown below), a push damp Airpot controls a mirror as it swings into position. The Airpot damping increases as the mirror approaches a stop, allowing rapid positive positioning without loud noise or impact damage.
In automatic mailing and addressing equipment it regulates the positioning mechanisms and feed roller pressure.
In spring loaded doors, x-y slides, and tape cartridge carriers it prevents damage on release.
|PULL DAMPING DIRECTION lbs force
(Starting from fully retracted position)
|PUSH DAMPING DIRECTION lbs force
(Starting from fully extended position)
|**Note: Best performance for each model will be achieved at or below input forces shown above. Maximum force capability is higher and is based on % of available volume displaced.|
