Description

Technical Field

[0001] The present invention relates to the technical field of planetary gear transmissions, in particular to a planetary gear transmission structure of any combination. Background Art

[0002] Planetary gear transmission is a transmission device designed based on planetary gear mechanism. It is widely used in automobile, industrial machinery and new energy fields due to its compact structure and high transmission efficiency. Its core consists of four major components: sun gear, planetary gear, planetary carrier and outer gear ring. Multi-speed shifting is achieved by fixing or linking different components. Among them, the planetary gear rotates around the central sun gear and meshes with the outer gear ring. When the input shaft drives the sun gear, the planetary gear revolves in the gear ring, driving the planetary carrier to output power. By locking different components (such as fixing the gear ring or planetary carrier), the transmission ratio can be switched. For example, when the gear ring is fixed, the power is input by the sun gear and output by the planetary carrier, achieving deceleration and torque increase; if the planetary carrier is fixed, it becomes a speed increase transmission.

[0003] However, the existing planetary gear transmission has a single output speed, and it is difficult to increase or decrease the number of gears according to the number of differential ratios, and it is difficult to increase or decrease the gear diameter according to torque requirements. There is also a problem that the gears cannot be freely combined according to actual needs to output different speeds; therefore, it does not meet the existing needs. In this regard, the present application proposes an arbitrary combination planetary gear transmission structure. Summary of the invention
