locking face 예문

예문

1. The pallets in a traditional lever escapement have two angled faces, the locking face and the impulse face, which engage the escape wheel teeth.
2. During the extremities of the pendulum's swing, the escape wheel tooth rests against this locking face, providing no impulse to the pendulum, which prevents recoil.
3. Near the bottom of the pendulum's swing the tooth slides off the locking face onto the angled " impulse " face, giving the pendulum a push, before the pallet releases the tooth.
4. Once the entrance tooth leaves the impulse plane of the entrance pallet, the wheel is able to turn a small amount ( called the drop ) until the exit tooth of the escape wheel lands on the locking face of the exit pallet.
