Internal Gears

INTERNAL GEARS

Internal gears are the gears which have their teeth inside cylinders or cones and are frequently used in planetary gear mechanisms. The internal gear always meshes with an external gear where the internal gear is always the large gear while the external gear is the pinion. In these cases, involute interferences, trochoid interferences, or triming may occur depending on the number of teeth of the meshing gears.
