Product details
1. Product Definition
TheDynamic 1022 Planetary Gear Reduceris a high-efficiency reduction device based on planetary gear transmission principles. It achieves power transmission and speed reduction through the meshing of a sun gear, planetary gears, and an internal ring gear. The model number "1022" typically represents the design version, specification parameters, or product series identifier, suitable for industrial applications requiring high torque, low backlash, and compact structures.

2. Core Structure
• Planetary Gear System:
• Sun Gear (Central Gear): Input power source.
• Planetary Gears (Multiple Small Gears): Revolve around the sun gear while rotating, transmitting torque.
• Internal Ring Gear (Fixed Outer Ring): Meshes with planetary gears to output reduced-speed power.
• Output Methods:
• Planetary Carrier Output(Common): High torque, low speed.
• Internal Ring Gear Output: Used in specific scenarios.
• Auxiliary Components:
• Bearings, seals, and lubrication systems (ensure long-term stable operation).
• Input/output flanges (adapt to motors or loads).

Parameter Description
Reduction Ratio Single-stage: 3:1~10:1; Multi-stage: Up to 1000:1 (varies by model).
Rated Torque Single-stage: 50~800 Nm; Multi-stage: Up to 5000 Nm (@1000 rpm, model-dependent).
Backlash Standard: ≤5~10 arc-min; High-precision: ≤1~3 arc-min (affects positioning accuracy).
Efficiency Single-stage ≥95%; Multi-stage ≥90% (efficiency decreases slightly with more stages).
Noise Level ≤65~75 dB (varies with speed and load).
Operating Temp. -20°C~+80°C (extended to -40°C~+120°C with special lubrication).
Protection Grade IP54 (standard); IP65 (dust/waterproof, optional).

4. Core Advantages
• High Torque Density: Delivers large torque in a compact structure, saving installation space.
• High Precision: Low backlash design (≤3 arc-min) for precise control applications.
• High Reliability: Multi-gear load-sharing design extends service life (MTBF ≥50,000 hours).
• Low Noise: Optimized gear meshing and bearing design reduce vibration.
• Modular Design: Supports rapid customization and expansion for diverse industry needs.

5. Typical Applications
• Industrial Automation:
• Robot joints, CNC machine tool spindles, packaging machinery.
• Renewable Energy:
• Wind turbine pitch systems, solar tracking drives.
• Logistics & Transportation:
• AGV vehicles, conveyor belt drives, warehousing sorting systems.
• Construction Machinery:
• Excavator slewing mechanisms, crane luffing systems.
• Automotive Industry:
• Electric power steering (EPS), hybrid vehicle transmission systems.
------
6. Selection & Customization Guide
• Requirements Confirmation:
• Input/output speed, torque, and power.
• Installation space, ambient temperature, and protection grade.
• Key Parameter Matching:
• Reduction ratio: Calculate based on motor speed and load requirements.
• Torque capacity: Reserve 20%~30% margin for peak loads.
• Customization Options:
• Special lubrication (food-grade, low-temperature grease).
• Custom output flanges (ISO, NEMA, or customer standards).
• Integrated brakes, encoders, or sensors.
------
7. Maintenance & Troubleshooting
• Routine Inspections:
• Lubricant level, temperature, and abnormal noise.
• Seal leakage, bolt loosening.
• Common Faults:
• Gear Wear: Insufficient lubrication or overloading (replace gear set).
• Bearing Failure: Excessive axial force (adjust installation or replace bearings).
• Oil Leakage: Aged seals (replace seals and replenish grease).
• Maintenance Intervals:
• Lubricant replacement: Every 2000 hours; comprehensive inspection: Every 5000 hours.
