GLW Series Planetary Gear Reducers feature a modular design, boasting compact size and high performance. They offer high efficiency, a high transmission ratio, a long lifespan, and low maintenance. They are easy to install and suitable for a variety of lifting and conveying applications, including truck cranes, ship cranes, tunnel excavation, construction cranes, dock cranes, and revolving stages. Our sophisticated planetary gear pair and reinforced bearing design ensure high radial force absorption and economical practicality, meeting the needs of a wide range of mobile and stationary applications.
Compact Size and High Torque Density:Small and lightweight, it offers high gear ratios (up to 100:1 or higher), saving approximately 50% space compared to parallel-shaft reducers, making it ideal for space-constrained applications such as robotics and automation.
High Efficiency and Low Energy Consumption:Planetary gears evenly distribute loads, achieving efficiency up to 98%, reducing friction and heat, lowering operating costs, and extending motor life.
Excellent Load Capacity: Supports high axial and radial loads, offers strong torsional rigidity, and accommodates heavy or pulsed loads, making it suitable for industrial machinery and transportation systems.
Low Backlash and High Precision: Low backlash (typically <5 arc minutes) and high positioning accuracy make it suitable for high-precision applications such as servo drives and CNC machine tools.
Long Life and Durability: Ball bearings and a robust construction reduce wear, vibration, and noise, while maintenance-free lubrication provides up to 20,000 hours of operation.
Versatile Configuration:Coaxial input/output shafts support multiple reduction stages (up to 10,000:1), compatibility with a wide range of motors, and flexible applications in industries such as automotive and construction.
1. What is the GLW Series Planetary Gear Reducer?
The GLW Series is an inline planetary gearbox designed for high-efficiency power transmission. It consists of a central sun gear, multiple planet gears orbiting around it, and an outer ring gear. This configuration reduces input speed from motors (e.g., servo or stepper) while multiplying torque, making it ideal for applications requiring precise motion control in limited spaces. It supports ratios from 3:1 to 100:1 in single-stage setups, with multi-stage options up to 10,000:1.
2. What are the key features of the GLW Series?
High Torque Density: Distributes load across multiple planet gears for superior torque output relative to size—up to 50% more efficient than parallel shaft reducers.
Low Backlash: Precision-engineered for <1 arcmin backlash, ensuring accurate positioning.
Compact and Lightweight: Reduces size by up to 50% compared to similar systems, with ball bearings for smooth operation and reduced wear.
Versatile Mounting: Options include foot, flange, or shaft mounting; inline configuration for aligned input/output shafts.
Durability: High axial/radial load capacity, IP-rated protection, and quiet operation due to balanced forces.
3. What applications is the GLW Series suitable for?
It's widely used in automation, robotics, food processing, medical devices, packaging, textiles, and transportation. Specific examples include servo-driven conveyors, patient lifts, automatic door openers, and CNC machinery. Its high torsional stiffness makes it perfect for precision tasks like robotics arms or high-speed indexing.
4. How does the GLW Series work?
The sun gear (connected to the motor input) drives the planet gears, which orbit inside the fixed ring gear. Torque is transmitted via the planet carrier to the output shaft, slowing speed and increasing torque. Efficiency remains high (up to 98% per stage) due to even load distribution. For multi-stage GLW units, each stage compounds the reduction for higher ratios.
5. How do I calculate the reduction ratio for the GLW Series?
For a single stage: Ratio (i) = (Number of ring gear teeth / Number of sun gear teeth) + 1. For multi-stage: Multiply ratios of each stage (e.g., two 4:1 stages = 16:1 total). Consider factors like efficiency (typically 90-95% per stage), input power, and torque needs. Use tools like manufacturer sizing software or formulas: Output Torque = Input Torque × Ratio × Efficiency. Consult specs for GLW tooth counts to avoid overload.
or custom designs.
6. What Maintenance Is Required for Slewing Reducers in Solar Systems?
Minimal due to sealed design: Inspect seals annually for cracks; regrease every 2 years (use high-temp lithium-based); check motor alignment and backlash quarterly. Monitor via encoders for position errors. In dusty/coastal areas, clean housings biannually. Lifespan: 20-30 years with proper care, far outlasting actuators in reliability.
