LIMING: SERVOBOX In-Line Planetary Reducers 1-Stage: SN-50-X

LI MING Machinery CO., LTD. is a specialist in the design, R&D and manufacturing of a wide range of high-tech gear motor and helical gear reducers, worm gear reducers, and planetary gear reducers. Among the wide range of speed reducers, the planetary gear reducers are widely applied in servo, stepping and DC transmission systems. With its outstanding feature of high precision transmission, the planetary gear reducer is excellent for reducing speed, increasing torque and reducing torsional inertia ratio. High torque, low backlash and low noise are three key features of LIMING's gear reducers.

SERVOBOX series high-precision planetary gear reducer employs helical gears. All gears are high-precision machined by a CNC gear hobbing machine, providing high-accuracy gear engagement, smooth running and minimum noise. LIMING gearbox is a one-piece fabricated. When compared with the competitive gear reducer, the LIMING gear reducer features smaller construction (saves over 1/4 of size and weight), higher output torque and higher transmission efficiency.

Features:

· Helical Gear Design

The speed reduction mechanism employs helical gears, which provides two times

meshing rate of teeth when comparing with regular spur gears. In addition, it also

features extremely smooth running, low noise, high torque output and low backlash.

· Collet Locking Mechanism

The input-end and the motor are coupled through a collet locking mechanism. It has passed dynamical balance analysis to assure concentricity and balance on the connection and no backlash for power transmission while running at high speed.

· Full Needle Roller Bearings Design

The planetary gear transmission employs full needle roller bearings without retainer to increase the contact surface, which greatly upgrades structural rigidity and service life.

· Integrated Planetary Arm Bracket

The planetary arm bracket and the output shaft are onepiece constructed to increase torsional rigidity and accuracy.

· One-piece Gear Box & Advanced Surface Treatment

The gear box and internal ring gear are one-piece constructed to achieve high rigidity and high torque.

· High Precision Gear Machining

Manufactured from high-quality Ni-Cr-Mo alloy steel (SNCM220), precision machined and carburized to hardness 57-60 HRC. Precision teeth grinding ensures gear accuracy reaches the DIN6 class.
