Information

 

Fork

 

Description

The fork applies a braking force on a gear. When the pendulum pushes on the fork, and if the translational position of the pendulum exceeds a certain threshold, the fork will release its grip on the gear. When the pendulum swings back, the grip will be restored. The fork also transfers energy from the escapement wheel to the pendulum to compensate for energy lost due to friction.

The escapement fork here is modeled using two rotational to translational components with opposite signs on their ratios. When one face of the fork goes down, the other swings up.

ClockWithOneHand

IndustryExamples.ConsumerProducts.PendulumClock

Main pendulum clock example. Clock has one hand that takes one step each second. The movement is controlled by a counterweight.

ClockWithTwoHands

IndustryExamples.ConsumerProducts.PendulumClock

Expanded pendulum clock setup with two hands, the relative motion of the hands are controlled by gear ratios.
