Dog Clutch Animation

The dog clutch block provides a choice of two torque transmission models. It functions by mating a set of regularly spaced teeth or protrusions on one half of the clutch mechanism to a set of identical recesses on the other rather than using the friction principle used in other clutches. Treat clutch engagement as a friction phenomenon between the ring and the hub.

Al budden made a similar dog clutch and has an animation showing how it works on his site.

Dog clutch animation. Dog clutches are used where slip is undesirable andor the clutch is not used to control torque. A drawback to this dog clutch is that it is more complex to build than my earlier auto stop. A dog clutch is a mechanism used to connect and disconnect two rotating shafts or machine parts. The dog clutch plus automatic stop mechanism stretches from headstock to tailstock.

Friction clutch approximate model. A dog clutch is a type of clutch that couples two rotating shafts or other rotating components not by friction but by interference. This model ignores special effects such as backlash an approximation that makes the block better suited for linearization fixed step simulation and. The two parts of the clutch are designed such that one will push the other causing both to rotate at the same speed and will never slip.
