ABSTRACT:
A rotary sprinkler has a step-down transmission between a turbine wheel drive and the sprinkler nozzle, which transmission includes a fixed ring gear having internal teeth coaxial with the drive rotary axis; a planet gear having external teeth engageable with, but fewer in number than, the internal teeth of the ring gear; and an eccentric pin secured to the rotary drive at its rotary axis and having a central axis laterally of the drive rotary axis. The eccentric pin is received within an opening centrally of the planet gear to cause the planet gear to planetate around the fixed ring gear and to rotate around the drive rotary axis at a step-down velocity determined by the difference in the number of teeth between the ring gear and the planet gear.
