SB double-stage planetary reducer

　　Liming reducer-SB series double-stage high-precision planetary reducer

Features:

Helical gear design: The reduction mechanism adopts helical gear design, and the tooth profile meshing ratio is more than twice that of ordinary spur gears. It has the characteristics of smooth running, low noise, high output torque and low backlash.

Full-needle needle bearing design: The transmission interface of the planetary gear adopts a full-needle needle bearing without a retainer to increase the contact area to improve structural rigidity and service life.

Collet type connection mechanism: The input end and the motor are connected by a collet type locking mechanism, and the dynamic balance analysis is carried out to ensure the concentricity and balance of the interface at high input speed, and the power transmission with zero backlash .

Product advantages:

Low noise: less than 74dB

Low backlash: accuracy within 9 arc minutes, 7 arc minutes, 5 arc minutes, 3 arc minutes can also be selected

High efficiency: up to 94% or more

Input speed: 3000-6000RPM

High torque: higher torque than general spur gear planetary reducer.

High stability: The use of high-strength alloy steel, the entire gear is hardened, not only the surface is hardened, to ensure the service life and long-term use to maintain the original precision.

High reduction ratio: Only modular design, planetary gearboxes can be connected to each other, and the speed ratio can reach 1/10000 or more.
