Abstract: A finger joint transmission structure of an anthropomorphic robot hand includes a first finger segment and a second finger segment that are pivotally connected to each other. A toothed rack in an arc shape is provided at the joint of the first finger segment and the second finger segment. The second finger segment has a speed reducer and a motor connected to the speed reducer therein. The speed reducer has a transmission shaft extending toward the toothed rack. A transmission gear meshing with the toothed rack is provided on the transmission shaft. When the motor drives the transmission shaft to rotate via the speed reducer, the transmission gear is synchronously driven to move along the toothed rack, so that the second finger segment is driven to be pivoted upward or downward at a predetermined angle relative to the first finger segment.

Abstract: A finger joint transmission mechanism of an anthropomorphic robot hand includes a first finger segment and a second finger segment that are pivotally connected to each other. A toothed rack in an arc shape is provided at the joint of the first finger segment and the second finger segment. The second finger segment has a power device and an inclined transmission unit therein. The transmission unit meshes with the toothed rack of the first finger segment. When the power unit drives the transmission unit to run, the transmission unit is driven to move along the toothed rack, so that the second finger segment is driven to be pivoted upward or downward at a predetermined angle relative to the first finger segment.

Abstract: A speed reducer includes a drive gear, at least two planetary gears and a fixed internal gear that are arranged in sequence in an inside-out direction and mesh with one another. A movable internal gear is coaxially arranged beside the fixed internal gear. The number of teeth of the movable internal gear is different from the number of teeth of the fixed internal gear. The planetary gears extend into the movable internal gear and mesh with the movable internal gear, respectively. The drive gear is arranged along an axis for driving the planetary gears to rotate between the drive gear and the fixed internal gear. Due to the difference in the number of teeth between the fixed internal gear and the movable internal gear, when the planetary gears are rotated, the movable internal gear is pushed and moved by the planetary gears to perform a reduction output.
