Gear-Pair : |
Two gear wheels with gear-teeth that are in mesh. When one gear rotates the other gear must also rotate. The angular velocity of each gear is related to the number-of-teeth on each gear-wheel. |
Driving Part : |
The rotating-Part that is kinematically-defined, and whose motion is defined (even if it is stationary) before you do Add Gear-Pair |
Driven Part : |
The rotating-Part whose motion is defined after you do Add Gear-Pair by the Driven-Part, the Number-of-Teeth on each Gear in the Gear-Pair, and the Mesh. |
External Mesh : |
The gears have teeth that diverge out from their centers-of-rotation. |
Internal Mesh : |
One of the gears has teeth that converge to its center-of-rotation. |
Simple Gear-Pair : |
Two gears that rotate about fixed centers. |
Epicyclic Gear-Pair : |
One gear orbits around the center of the other gear. |
There are three Parts. There is a Line in a Part that is kinematically-defined. The Line must have a dimension to define its length. A Part is joined with a Pin-Joint to each end of the Line - two rotating-Parts. One rotating-Part is kinematically-defined. The other rotating-Part is not kinematically-defined before you do Add Gear-Pair. The three Parts have one degree-of-freedom. |
Add Gear-Pair removes the one degree-of-freedom from the three Parts. The motion of Driven Part is found from the number-of-teeth , and mesh on each gear-wheel in the Gear-Pair. |
Add Gear-Pair removes one degrees-of-freedom.
