KB series precision servo planetary reducer

Precision servo planetary gear reduction’s coaxial base model are as follows:KB40, KB60, KB90, KB115, KB142, KB180, KB220, KB280; speed ratio: 3~1000 has more than 20 ratios; one, two, three-stage reduction transmission; accuracy: one level The transmission accuracy is 4-6 arc minutes, the secondary transmission accuracy is 6-8 arc minutes; the third-stage transmission accuracy is 7-10 arc minutes; there are hundreds of specifications, and it is also possible to customize the production of non-standard planetary gear box.

Performance and features of KB series precision servo planetary gear transmission:

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

2. Using 3D / PORE design analysis technology, the tooth surface and lead trimming of the spiral tooth surface, to reduce the impact and noise of the gear to bite and bite, increase the service life of the gear train;

3.The servo planetary gear drive’s gear material is made of high-grade chromium-molybdenum-vanadium alloy steel. After quenching and tempering heat treatment to the substrate hardness of 30HRC, the hardness of the gear surface is nitrided to 840HV by using the advanced ion nitriding equipment of the factory to obtain the best wear resistance. Consumption and impact toughness;

4. The precision servo planetary gear motor 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, using NYOGEL792D synthetic grease, and using IP65 protection grade sealing design, the lubricant does not leak, maintenance-free;

6. The connection between the input end of KB series precision servo planetary gear transmission and the motor adopts a collet type locking mechanism and is analyzed by dynamic balance to ensure the concentricity of the interface and the power transmission of the zero back gap at high input speed;
7. The sun gear made by the whole gear bar has strong rigidity and accurate concentricity;

8, the unique motor connection plate and bushing modular design, suitable for any servo motor;

9. The surface of the servo planetary gear box is treated with electroless nickel, and the motor connecting plate is treated with black anode to improve the environmental resistance and corrosion resistance;
10. The Precision planetary gear reduction and inner ring gear adopt an integrated design, which is compact in structure, high in precision and large in output torque.

In summary:

KB series precision servo planetary gear drive: It is a coaxial square flange output with high precision, good rigidity, large bearing capacity, high efficiency, long life, low noise, light size, beautiful appearance, convenient installation and accurate positioning. It is suitable for communication. Acceleration and reduction transmission of servo motors, DC servo motors, stepping motors, and hydraulic motors. It is suitable for the connection of drive products made by any manufacturer in the world, such as: Panasonic, Delta, Yaskawa, Fuji, Mitsubishi, Sanyo, Siemens, Schneider, Fanak, Kobe, Kollmorgen, AMK, Parker, etc.
