Abstract
In an eccentric gear in which the gear rim of a first orbiting cog wheel is in engagement with the gear rim of a second rotating cog wheel, the two gear rims are offset from each other by an eccentricity. The second cog wheel is fixed to a driven shaft seated in a fixed housing. At least three eccentric shafts, which are evenly spaced about the circumference of the cog wheel, are provided for guiding the orbiting cog wheel, the eccentrics of each shaft being seated in respective bores of the orbiting cog wheel. One of the three eccentric shafts extends through the housing wall on one side and is formed as the drive shaft. The three eccentric shafts are coupled via a slider orbiting with an eccentricity which is considerably greater compared with the drive eccentricity.
