US3640150A — Power driven actuator of the compound planetary g…

Claim 1

Independent Claim 234 words

A power driven actuator of the compound planetary gear type for actuating a member through a push-pull linkage, the actuator comprising: a. coaxially arranged rotatable ring gears connected to said linkage; b. a plurality of planet members spaced circumferentially with respect to said rotatable ring gears; c. each planet member comprising a central pinion gear portion and end pinion gear portions on opposite sides of the central pinion gear and having pitch circles of diameters different in size from that of said central pinion gear portion; d. each of the planet members being disposed so that the central pinion gear portion and the end pinion gear portions mesh with said rotatable ring gears to rotate the latter; e. drive means for causing said planet members to planetate; and f. a pair of fixed ring gears disposed with one fixed ring gear in meshing relationship with each of the end pinion gears on one side of the central pinion gear and the other fixed ring gear in meshing relationship with each of the end pinion gears on the other side of the central pinion gear; g. said rotatable ring gears having different size pitch circles and each of said fixed ring gears having a pitch circle of a size intermediate the diameters of the pitch circles of the rotatable ring gears so that said rotatable ring gears are rotated in directions opposite to each other.

Claim 2

Dependent Claim 234 words

A power driven actuator of the compound planetary gear type for actuating a member through a push-pull linkage, the actuator comprising: a. coaxially arranged rotatable ring gears connected to said linkage; b. a plurality of planet members spaced circumferentially with respect to said rotatable ring gears; c. each planet member comprising a central pinion gear portion and end pinion gear portions on opposite sides of the central pinion gear and having pitch circles of diameters different in size from that of said central pinion gear portion; d. each of the planet members being disposed so that the central pinion gear portion and the end pinion gear portions mesh with said rotatable ring gears to rotate the latter; e. drive means for causing said planet members to planetate; and f. a pair of fixed ring gears disposed with one fixed ring gear in meshing relationship with each of the end pinion gears on one side of the central pinion gear and the other fixed ring gear in meshing relationship with each of the end pinion gears on the other side of the central pinion gear; g. said rotatable ring gears having different size pitch circles and each of said fixed ring gears having a pitch circle of a size intermediate the diameters of the pitch circles of the rotatable ring gears so that said rotatable ring gears are rotated in directions opposite to each other.

Claim 3

Dependent Claim 63 words

A power driven actuator of the compound planetary gear type for actuating a member through a push-pull linkage, the actuator comprising: a. a housing; b. a drive shaft journaled in said housing and connected to a source of rotary power; c. a sun gear in said housing rotated by said drive shaft; d. a plurality of planetary gears; e. each planetary gear having;

Claim 4

Dependent Claim 63 words

A power driven actuator of the compound planetary gear type for actuating a member through a push-pull linkage, the actuator comprising: a. a housing; b. a drive shaft journaled in said housing and connected to a source of rotary power; c. a sun gear in said housing rotated by said drive shaft; d. a plurality of planetary gears; e. each planetary gear having;

Claim 5

Dependent Claim 12 words

an end gear portion on opposite sides of said central gear portion;

Claim 6

Dependent Claim 12 words

an end gear portion on opposite sides of said central gear portion;

Claim 7

Dependent Claim 184 words

said end gear portion having pitch circles of smaller diameters than the diameter of the pitch circle of said central gear portion; f. the central gear portion of each planetary gear being disposed in meshing relationship to the sun gear to be driven by the latter; g. a first annular output ring gear means supported for rotation in said housing and in meshing relationship with said central gear to be driven by the latter; h. a pair of second annular output ring gears means supported for rotation in said housing with one of each disposed in meshing relationship with one of the end gear portions of the planetary gear; and i. at least one fixed ring gear secured to said housing and having a pitch circle intermediate in size between the pitch circles of the first and second output ring gears means and disposed in mesh with one of the end gear portions in the addendum area of the gear teeth of the latter to thereby effect rotation of said first and second ring gear means in opposite directions and relative to the housing.

Claim 8

Dependent Claim 184 words

said end gear portion having pitch circles of smaller diameters than the diameter of the pitch circle of said central gear portion; f. the central gear portion of each planetary gear being disposed in meshing relationship to the sun gear to be driven by the latter; g. a first annular output ring gear means supported for rotation in said housing and in meshing relationship with said central gear to be driven by the latter; h. a pair of second annular output ring gears means supported for rotation in said housing with one of each disposed in meshing relationship with one of the end gear portions of the planetary gear; and i. at least one fixed ring gear secured to said housing and having a pitch circle intermediate in size between the pitch circles of the first and second output ring gears means and disposed in mesh with one of the end gear portions in the addendum area of the gear teeth of the latter to thereby effect rotation of said first and second ring gear means in opposite directions and relative to the housing.

Claim 9

Dependent Claim 39 words

The mechanism of claim 2, wherein each of said first and second ring gear means includes an arm which is pivotally connected at its distal end portion of the push-pull linkage to effect actuation of a pivotally mounted member.

Claim 10

Dependent Claim 15 words

The mechanism of claim 2, wherein said housing is pivotally secured to a fixed structure.

Claim 11

Dependent Claim 43 words

The mechanism of claim 2, wherein a fixed ring gear is secured at opposite ends of the housing with each fixed ring gear in mesh with one of the end gear portions in the addendum area of the gear teeth of the latter.
