Solution Overview
Problem
Existing gear mechanisms face challenges in efficiently transmitting power while maintaining high torsion and speed, as they often result in reduced rotating speed and increased friction, limiting their efficiency in applications requiring high power output.
Innovation Solution
A gear-lever mechanism using meshing and pushing, which incorporates a shell, input device, output device, and positioning device with idler gears and transfer-layer gears arranged to form a planetary meshing-pushing rotation, allowing the driven gear set to rotate at an increased speed and torque through a small driving gear, enhancing transmission efficiency.

Engineering Contradiction Analysis
1Speed
If conventional gear meshing is used to transmit power, then torsion can be maintained, but rotating speed is reduced
Solution Approach 1:
The patent applies dynamics by making the gear system movable and adjustable through the combination of sun gear, planet gears, and ring gear that can rotate and mesh dynamically. The planet gears orbit around the sun gear while simultaneously rotating on their own axes, creating a dynamic transmission system that can achieve both speed increase and power output through controlled motion patterns.
Solution Approach 2:
The planet gears serve as intermediaries between the sun gear and the ring gear, transferring power and motion through their meshing relationships. This intermediary mechanism allows the system to achieve complex motion transformation, where the planet gears both rotate on their axes and orbit around the sun gear, enabling simultaneous speed increase and power transmission.
2Productivity
If gear accuracy is improved to increase transmission efficiency, then manufacturing complexity increases
Solution Approach 1:
The patent segments the gear system into distinct components: sun gear, multiple planet gears, and ring gear. Each component can be manufactured separately with standard gear machining processes, then assembled together. This segmentation allows for easier manufacturing and maintenance while maintaining transmission efficiency through proper gear meshing design.
Solution Approach 2:
The patent utilizes parameter changes by varying the number of teeth on different gears (sun gear has Z1 teeth, planet gears have Z2 teeth, ring gear has Z3 teeth) to achieve desired transmission ratios. By changing these discrete parameters, the system can be optimized for different efficiency requirements without requiring complex manufacturing processes.
3Productivity
If friction of gear meshing is decreased to improve efficiency, then manufacturing precision requirements increase
Solution Approach 1:
The patent ensures continuous useful action through the engagement of multiple planet gears with the sun gear and ring gear simultaneously. This continuous meshing of multiple gear pairs distributes the load and maintains constant power transmission, reducing the impact of individual gear imperfections and minimizing friction through sustained smooth operation.
Solution Approach 2:
The patent changes parameters by selecting appropriate gear tooth counts (Z1, Z2, Z3) and gear ratios to optimize meshing conditions. By carefully selecting these parameters, the system achieves smooth gear engagement that minimizes friction and impact loads, thereby improving transmission efficiency without requiring extremely tight manufacturing tolerances.

AI summary
A gear-lever mechanism using meshing and pushing for rotation includes a shell; an input device including a driving gear; an output device including a supporting frame and a driven gear set; and a positioning device including a fixed bearing gear. The driven gear set includes a transfer-layer gear and at least one idler gear. The supporting shaft center of each transmission gear in the driven gear set is the sub-bearing point, with each transmission gear meshed with its adjacent drive gears to form two meshing points. The bearing point and the two meshing points form a triangular pushing area. At least two triangular pushing areas in head-to-tail connection form a meshing-pushing-lever-type torsion-output path curved from the driving gear to the fixed bearing gear for connecting and driving, to cause the gear set to rotate with a raising speed, and then reduce the speed and increase the torque.
