   1. The gear interface of the planetary gear (Gear) adopts a full-needle needle bearing without a retainer to increase the contact area to improve the structural rigidity and output torque;                                                                                                                          

   2, using 3D / PORE design analysis (Analyse) technology, respectively, the helical tooth surface for tooth profile and lead trimming, to reduce the gear (Gear) impact and noise of the bite and bite, increase the use of the gear train duration;


   3. Gear material is made of high-grade Chromium molybdenum-vanadium alloy. After quenching and tempering heat treatment (chǔ lǐ) to a substrate hardness of 30HRC, we use our advanced ion nitriding equipment. Shèbèi) nitriding the hardness of the gear surface to 840HV for optimum wear resistance and toughness;

   4. The planetary boom and the output shaft adopt an integrated structural design, and the bearing configuration of the output shaft adopts a large span design to ensure maximum torsional rigidity and output load capacity;                                                 

   5. The oil seal contact interface at the output end adopts advanced titanium nitride coating, the surface hardness is more than 2000HV, and the surface roughness of the contact surface is less than Ra below 0.2μ, which ensures the lowest friction coefficient and the lowest starting torque;

    6, using NYOGEL792D synthesis (interpretation: from several parts into a whole) Lubricating oil grease, and using IP65 protection grade sealing design, the lubricant does not leak, maintenance-free;                                                                                                       

    7. The connection between the input terminal and the motor and engine adopts a collet-type locking mechanism and is subjected to dynamic balance analysis (Analyse) to ensure the concentricity of the interface and the power transmission of zero backlash at high input speed ( Transmission);                                                                                                                                                         

   8. The sun gear made by the whole gear bar has strong rigidity and accurate concentricity;

   9, unique (interpretation: unique, special) modular design of the motor connection plate and bushing, suitable for any servo motor;

   10. The surface of the gearbox is treated with electroless nickel (chǔ lǐ), and the motor and engine connecting plate are treated with black anode to improve environmental tolerance and corrosion resistance.

   11. The gear box and the inner ring gear adopt an integrated design, which is compact in structure, high in precision (unit: g/cm3 or kg/m3), and has large output torque. Hardened gear reducer is a rotary mechanism widely used in East China and East China for tower-introduction crane machinery. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, 

textile, printing and dyeing. In the field of pharmaceuticals. The efficiency of the hardened gear reducer drive is the most efficient of all drives, and its efficiency is much higher than that of the worm drive. The efficiency of the gear reducer is mainly determined by the friction of the gear and the bearing. Planetary gear reducers are also known as planetary reducers and servo reducers. In the 

family of reducers, planetary reducers are widely used in servo systems, stepping motors, DC motors and other transmission systems due to their small size, high transmission efficiency, wide deceleration range and high precision. Its role is to reduce the speed increase torque and reduce the load/motor moment of inertia ratio under the premise of ensuring precision transmission.高
