A planetary gear device includes: a first internal gear and a second internal gear, a first external gear which meshes with the first internal gear, a second external gear which meshes with the second internal gear, and an eccentric body which circumferentially moves the first external gear and the second external gear. The first external gear and the second external gear each independently have external teeth and are connected to each other to integrally rotate with each other, the first internal gear and the second internal gear each independently have internal teeth, one of the first internal gear and the second internal gear is connected to a stationary side, and the other thereof is connected to an output side, and each of the first internal gear and the second internal gear has internal teeth which are constituted by a support body, and a rotating body rotatable to the support body.

A packaged oil delivery with integral flow restrictor including a dispenser assembly and a restriction assembly. The dispenser assembly includes a dispenser that is to be mounted on a mechanical system to enhance lubrication of gears, bearings, shafts, seals, and the like. As elements of mechanical systems often rotate at high/low RPM, the channels are intended to slow/expedite the speed in which oil is passively delivered onto the aforementioned components. The restriction assembly includes channels internally disposed within the dispenser to passively meter the flow of oil being expelled. The speed with which the oil is expelled from the inside of the dispenser is directly related to the length and pattern that the channel has.
