LIMING: SERVOBOX In-Line Planetary Reducers 2-Stage: SB-120-XX-P2

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 provide two times the meshing rate of teeth when compared with regular spur gears. In addition, it also features extremely smooth running, low noise, high torque output and low backlash.

· Synthetic Lubrication Grease

The protective class IP65 sealed design avoids leakage problems. It features no maintenance.

· 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 a 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 one-piece constructed to increase torsional rigidity and accuracy. The entire structure is one-time machined one for controlling accuracy in the specified tolerance.

· High Precision Gear Machining

The planetary gear and sun gear are made of high quality Ni-Cr-Mo alloy steel (SNCM220), precision machined and carburized to hardness 57-60 HRC. Precision teeth grinding assures gear accuracy reaches the DIN6 class. It provides better wear resistance, impact resistance and longer service life than gears with only surface nitriding.

· One-piece Gear Box & Advanced Surface Treatment

The gearbox and internal gear ring are one-piece constructed, which is made of Cr-Mo alloy steel (SCM440), and tempered for high torque output. High gear accuracy meets DIN6 class standard. The gearbox surface is anticorrosive treated for upgrading environmental resistance and corrosion-resistant capability.

· CAE Design and Analysis

Employing 3D-CAE software for analysis and design, the software allows for analyzing the strength of the entire gear reducer and modifying the helical teeth profile and lead. This reduces the impact and noise during teeth engage and disengage while increasing the service life of gears and the gear reducer.

· Modular Design of Motor Connection Plate

The special modular design of the motor connection plate is suitable for any brand and any type of servomotor. It is made of aluminum alloy. Its surface is anti-oxidant treated for upgrading environmental-resistant and corrosion-resistant capability.
