SIMPLE PLANETARY REDUCTION GEAR
A simple planetary reduction gear includes a sun gear, a planetary gear which revolves around the sun gear and is supported by a carrier, and an internal gear with which the planetary gear internally meshes, and is used in a vertically installed state. The sun gear includes a shaft portion protruding to a load side (lower side) coaxially with a shaft center O1 of the sun gear, and the shaft portion is supported by a ball bearing which is disposed between the outer circumference of the shaft portion and the inner circumference of the carrier. Accordingly, high maintainability is secured and a problem of generation of heat is prevented.
