Patent ID: 11441640

Abstract:
A balanced speed reducer of a dual-ring gear variable-line-speed planetary row includes a dual-ring gear variable-line-speed planetary row, an input end (6), an output end (7), a locking end (8), and auxiliary devices such as bearings. The dual-ring gear planetary row includes a left ring gear (1), a right ring gear (2), and a planet carrier (3). A left planetary gear (4) and a right planetary gear (5) that are connected on each planetary gear shaft have the same rotation speed. The left planetary gear (4) meshes with the left ring gear (1), and the right planetary gear (5) meshes with the right ring gear (2). The number of gear sets is not less than two. A teeth number combination and a number of gear sets are set according to a range specifying parameter and following a principle of matching the teeth number combination with the number of gear sets. A rule for manufacturing and assembling planetary gears is executed. A regulation on gear reference circle radii is executed. By connecting the planetary carrier (3) to the input end (6), connecting one ring gear to the output end (7), and connecting the other ring gear to the locking end (8), a speed reducer that has a corresponding left transmission ratio and right transmission ratio, can be actually assembled and provides balanced operation is formed.
