Planetary gears: the intelligent core of mechanical transmission - Technical analysis by Shandong Prior Machinery Manufacturing Co., Ltd.
1. Why is the structure of planetary gears called a "mechanical solar system"?
The planetary gear system consists of four core components: sun gear, planetary gear, planetary carrier and ring gear. Its operating mode is highly similar to the movement of the planets in the solar system: the sun gear is the central driving gear, the planetary gear rotates around its own axis and revolves around the sun gear with the planetary carrier, and the ring gear is a fixed or adjustable peripheral structure, forming a precise multi-stage power transmission path. This unique "revolution + rotation" compound motion mode makes it a model of efficient transmission.
Pureer's practice: The company has passed the IS09001 and ISO/TS16949 quality management system certification to ensure the processing accuracy and assembly consistency of each set of planetary gear components, avoiding the problem of running jams caused by minor errors.
2. Why can planetary gears become the core of "hybrid artifact" and industrial transmission?
The "power splitting" characteristics of planetary gears make them shine in hybrid power systems. For example, Toyota's THS hybrid system achieves seamless coupling of engine power and motor power through a planetary gear set, with 72% of the torque distributed to the drive wheels and 28% used for power generation, significantly improving energy efficiency. In the industrial field, its compact design, high load-bearing capacity (multiple planetary gears share the load) and multi-transmission ratio characteristics make it widely used in high-precision scenarios such as wind power generation and robot joints.
Prior's solution: The company provides customized planetary gearbox design, supporting transmission structures from single to multi-stage, covering a speed ratio range of 3:1 to 100:1 or more, meeting the diversified needs of automobiles, wind power, automation equipment, etc., and promises a three-year product warranty to ensure long-term stable operation.

3. How to achieve flexible regulation of the transmission ratio of planetary gears?
By locking different components (such as fixed ring gear, sun gear or planet carrier), planetary gears can output differentiated speed ratios and rotation directions. For example, when the ring gear is fixed, the transmission ratio can reach 5:1; when the planet carrier is fixed, reverse rotation is achieved, which is suitable for reversing scenarios.
Prior's innovative optimization: The company uses professional gear design software, combined with positive/negative displacement technology, to solve the meshing problem of traditional standard gears, ensure transmission stability, and control the defect rate below 0.2%.

4. How to balance the advantages of planetary gears in heavy machinery and precision equipment?
Advantage comparison:
High efficiency and low loss: The transmission efficiency of planetary gears reaches 97%-99%, which is much higher than the 50%-80% of worm gears.
Compactness and high load: The multi-planetary gear load-balanced design can withstand giga-Newton-level torque while maintaining a lightweight structure. Prior's technological breakthrough: The company provides titanium alloy and composite gear solutions for heavy equipment, combined with intelligent monitoring systems, to optimize the operating status in real time, reduce noise and wear, and extend life.
