ZDH Series Planetary Hard Tooth Surface Gear Reducer 4-100 Ratio 0.25-75kW High Torque Density IP65 for Servo Drive

ZDH Series Planetary Hard Tooth Surface Gear Reducer

The ZDH Series Planetary Hard Tooth Surface Gear Reducer combines compact planetary transmission architecture with alloy steel quenched hard tooth surface technology to deliver exceptional torque density in minimal space. Engineered for high-precision, high-response applications, this reducer features controllable backlash, smooth low-noise operation, and versatile mounting interfaces – making it the ideal choice for servo drive systems, automation manipulators, robot joints, machine tool transmissions, and precision industrial equipment.

Product Features

• Planetary Gear Architecture – Compact coaxial design delivers substantially higher torque density than parallel-shaft reducers in a significantly smaller footprint
• High Torque with Shock Resistance – Alloy steel quenched hard tooth surface gears provide exceptional overload capacity, ideal for heavy-duty startup conditions
• Precision Backlash Control – Controllable gear backlash meets demanding precision transmission requirements for servo-driven automation systems
• Smooth Low-Noise Operation – Optimized planetary gear meshing ensures quiet, vibration-free running suitable for automation equipment and robotic applications
• Versatile Integration Interfaces – Extensive mounting options including flanges, base mounts, and servo interfaces enable direct connection with motors, ball screws, and adjacent gearboxes

Primary Applications

• Servo Drive Systems
• Automation Manipulators
• Robot Joint Transmissions
• Machine Tool Drive Systems
• Packaging Equipment
• Precision Conveyor Lines
• Crane Slewing Mechanisms

Installation & Operation Notes

1. Never strike the output flange or housing surfaces during installation
2. Ensure precise coaxial alignment between input shaft and motor output shaft
3. Never exceed rated torque, rated speed, or allowable radial load
4. Verify adequate grease or oil quantity before initial startup
5. Stop immediately if abnormal noise, temperature rise, or vibration occurs during operation
6. Follow correct assembly sequence for planet gears, sun gear, and ring gear during maintenance disassembly

Packaging

Standard models are packed with foam inner lining in cartons or plywood crates. Precision-grade models are shipped in aluminum alloy cases or fully sealed plywood crates with internal shock-proof protection. Flanges, shaft ends, keyways, and mounting holes receive individual protective wrapping. Documentation, precision inspection reports, and certificates are packed separately in waterproof bags. External markings include precision equipment, moisture-proof, shock-proof, handle-with-care, and lifting point labels.
