About Our Planetary Gear Reducers
OUBANG MOTOR specializes in planetary gear reducers and gearboxes for industrial automation. We offer economy spur gearboxes for cost-effective solutions and precision helical planetary gear reducers for high-precision motion control.
Our designs feature compact size, high torque density, low backlash (down to 3 arc-min), and efficiency up to 97% per stage. Ratios from 3:1 to 512:1 cover a wide range of servo, stepper, and induction motor applications.
Core Specifications
- Flange sizes: 60 / 80 / 90 / 120 (economy spur); 60 / 80 / 90 / 120 / 150 / 180 / 220 (precision helical)
- Ratios: 3:1 to 512:1 (single and two-stage configurations)
- Backlash (typical): economy spur ~10–20 arc-min; precision helical ~3–10 arc-min
- Efficiency: up to 95–97% per stage (helical line offers lower noise)
- Mounting: ISO flange; ready for servo, stepper, and induction motor adapters
- Output options: keyed or clamp shaft, solid or flange output
- Construction: alloy steel, carburized & ground gears; rigid housing; lifetime lubrication
Why Choose Our Planetary Gear Reducers?
- High torque in a compact footprint thanks to multiple gear meshes
- Low backlash for accurate positioning and repeatability
- High efficiency and long service life with hardened, ground gears
- Quiet operation with helical gearing for noise-sensitive environments
Typical Applications
- Robotics and cobots, AGVs/AMRs
- CNC machinery, machine tools, and indexing tables
- Packaging, labeling, pick-and-place systems
- Conveyors, material handling, and palletizing
- Printing and textile equipment
Selecting the Right Gearbox
Choose economy spur when you need reliable torque at the best value. Choose precision helical when low noise, tighter backlash, and smooth motion are critical. Provide motor type, speed, required output torque, ratio, and mounting size—we’ll recommend the optimal match.
