However, miniaturization in the traditional sense usually focuses on directly reducing the volume of the machine or proportionally reducing the mechanical device, and the resulting tiny machine has some unavoidable defects.
The traditional planetary gear transmission has obvious advantages in terms of volume and smooth performance compared with the traditional gear transmission, but the structure of the high-power high-speed planetary gear transmission is more complicated, and the required manufacturing precision is relatively high, which makes the planetary gear in the field of miniaturization. faced more problems

The invention discloses a planetary gear transmission device. The planetary gear transmission device comprises a sun gear, a planetary gear and an outer gear, wherein the sun gear comprises a sun mainbody part and a sun hook rod arranged on the outer side surface of the sun main body part, and the sun hook rod is in a cylindrical spiral shape; the planetary gear comprises a planetary main body part and a planetary hook rod arranged on the outer side surface of the planetary main body part, and the planetary hook rod is in a cylindrical spiral shape; the outer gear comprises an outer frame body and outer gear hook rods arranged on the inner side surface of the outer frame body, and the outer gear hook rods are both cylindrical spiral shapes; both the sun gear and the planetary gear are arranged in the outer frame body; and when the planetary gear transmission device rotates, continuous meshing transmission is formed between the sun hook rod and the planetary hook rod, and continuous meshing transmission is formed between the planetary hook rod and the outer gear hook rod. Compared with a planetary gear transmission mechanism of a traditional gear, the planetary gear transmission device is low in cost and low in vibration and noise.
Description
technical field [0001] The invention relates to the technical field of micro-electro-mechanical systems, in particular to a planetary linear gear transmission. Background technique [0002] Advances in science and technology have led to an increasing demand for micro-machines. Mechanical miniaturization has become a common pursuit in the field of mechanical design in contemporary society. However, miniaturization in the traditional sense usually focuses on directly reducing the volume of the machine or proportionally reducing the mechanical device, and the tiny machine thus obtained has some unavoidable defects. The traditional planetary gear transmission has obvious advantages in terms of volume and smooth performance compared with the traditional gear transmission, but the structure of the high-power high-speed planetary gear transmission is more complicated, and the required manufacturing precision is relatively high, which makes the planetary gear in the field of miniat...
