Variable velocity sprinkler transmission

Variable velocity sprinkler transmission

A sprinkler having a water-driven drive mechanism or motor for rotating a sprinkler head is disclosed where the drive mechanism converts a constant input rate into a variable rate to reduce tailing from overly-rapid rotation and to promote full develop of water stream discharge profile. The drive me...

Zusammenfassung:A sprinkler having a water-driven drive mechanism or motor for rotating a sprinkler head is disclosed where the drive mechanism converts a constant input rate into a variable rate to reduce tailing from overly-rapid rotation and to promote full develop of water stream discharge profile. The drive mechanism includes continuously engaged members including one or more planet gears each having an offset or eccentrically positioned engagement portion for driving a second gear member. As the planet gear rotates, the movement of the engagement portion has a radial component relative to the second gear, and the rotational velocity of the second gear is related to the radial position of the engagement portion.
