Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
In a planetary gear unit, the combination of a sun wheel, a ring gear, a set of planet wheels meshing with said sub wheel and with said ring gear, a planet wheel carrier adapted to be rotated in one direction when the sun wheel is driven, a set of shafts supported by said carrier, and a set of sleeves eccentrically mounted on said shafts so that the axes of the shafts are offset from the axes of said sleeves in a direction opposite to said one direction of rotation of said carrier, said planet wheels being rotatably mounted on said sleeves concentrically with the sleeve axes, the gear unit being further characterized in that said sleeves with said planet wheels thereon are eccentrically selfadjusting independently on one another on their respective shafts.
Claim 2
Dependent Claim
132 words
In a planetary gear unit, the combination of a sun wheel, a ring gear, a set of planet wheels meshing with said sub wheel and with said ring gear, a planet wheel carrier adapted to be rotated in one direction when the sun wheel is driven, a set of shafts supported by said carrier, and a set of sleeves eccentrically mounted on said shafts so that the axes of the shafts are offset from the axes of said sleeves in a direction opposite to said one direction of rotation of said carrier, said planet wheels being rotatably mounted on said sleeves concentrically with the sleeve axes, the gear unit being further characterized in that said sleeves with said planet wheels thereon are eccentrically selfadjusting independently on one another on their respective shafts.
Claim 3
Dependent Claim
42 words
The planetary gear unit as defined in claim 1 together with a set of spherical bearing members provided on the respective shafts, said sleeves with their associated planet wheels being rockable on said bearing members in planes parallel to the shaft axes.
Claim 4
Dependent Claim
23 words
The planetary gear unit as defined in claim 1 together with antifriction bearing means provided between said sleeves and the respective planet wheels.
