  Gear Reducer	- Type: Helical gearbox (parallel shaft) - Reduction Ratio: 20:1 (adjustable via optional ratios: 10:1~100:1) - Output Speed: 75 rpm (at 50Hz input, 20:1 ratio) - Rated Output Torque: 500 Nm (continuous); 1000 Nm (peak, 10s) - Gear Material: Case-hardened alloy steel (20CrMo) - Lubrication: Synthetic gear oil (lifetime lubrication for 10,000 hours @ 75℃)	Helical gears ensure low noise (<75dB) and high efficiency (≥95%); 500Nm torque handles heavy loads (e.g., loaded conveyors, industrial mixers)

• Mechanical & Operational Specifications:

  Parameter	Details	Performance Metrics
  Mechanical Design	- Output Shaft: Keyed solid shaft (30mm diameter) - Mounting Type: Foot-mounted (IEC standard flange) - Housing Material: Cast iron (GG25) with anti-corrosion coating - Protection Rating: IP55 (dust-tight, water jet-resistant) - Weight: Approximately 120kg - Cooling: Natural convection + forced air (optional fan for high ambient temperatures)	IP55 rating suits dusty/wet industrial environments; cast iron housing withstands mechanical stress and vibration
  Operational Limits	- Duty Cycle: S1 (continuous operation) - Overload Capacity: 150% rated torque (1 minute, 10 cycles/hour) - Direction of Rotation: Reversible (via phase reversal) - Thermal Protection: Built-in PTC thermistor (120℃ trip)	S1 duty rating supports 24/7 operation (e.g., continuous conveyors); PTC thermistor prevents motor burnout from overheating

• Environmental Ratings:

  Parameter	Details	Performance Metrics
  Operating Conditions	- Operating Temperature Range: -10℃~+40℃ (+40℃~+60℃ with 10% derating) - Storage Temperature Range: -25℃~+70℃ - Humidity Tolerance: 5%~95% RH (non-condensing) - Vibration Resistance: 10~100Hz, 10m/s² acceleration (IEC 60068-2-6) - Shock Resistance: 30m/s² (11ms half-sine, IEC 60068-2-27)	Wide temperature range suits unconditioned industrial spaces; vibration resistance prevents gear loosening in high-vibration environments (e.g., near pumps)

• Compliance Standards: CE, UL 1004, IEC 60034 (motors), IEC 60072 (gear units), RoHS, ISO 9001 |

2. Core Features

• Integrated Motor-Gearbox Design: Combines a 4.0kW IE3 motor with a 20:1 helical gearbox in a single cast iron housing—eliminates the need for separate motor-gearbox alignment, reducing installation time by 50% and minimizing misalignment-related wear (e.g., bearing failure, gear tooth damage).
• High Torque Output: 500Nm continuous torque (1000Nm peak) with 20:1 reduction—handles heavy mechanical loads (e.g., loaded conveyors, industrial mixers) without performance degradation, ensuring reliable operation in demanding applications.
• Energy Efficiency: IE3 motor efficiency (≥91%) and high gearbox efficiency (≥95%)—reduces energy consumption by 10%~15% compared to IE2 motor + standard gearbox combinations, lowering operational costs for 24/7 systems.
• Durable Construction: Cast iron housing (GG25) with anti-corrosion coating and case-hardened alloy steel gears—withstands mechanical stress, vibration, and harsh industrial environments (e.g., dust, water jets) for a service life of 10,000+ operating hours.
• IP55 Protection: Dust-tight and water jet-resistant enclosure—suitable for outdoor installations (e.g., construction equipment) and wet environments (e.g., food processing washdown areas), reducing maintenance needs in harsh conditions.
• Flexible Speed Control: Compatible with ABB ACS-series VFDs—enables variable speed adjustment (5~50Hz) for applications requiring precise speed control (e.g., packaging lines with variable product sizes); reversible rotation supports bidirectional loads (e.g., elevators).
• Built-In Protection: PTC thermistor (120℃ trip) and 150% overload capacity—prevents motor burnout from overheating or mechanical jams (e.g., conveyor blockages); reduces downtime and repair costs in fault scenarios.

3. Application Fields

• Material Handling & Logistics: Conveyor and elevator systems:
  • Heavy-Duty Conveyors: Drives 4.0kW belt conveyors in warehouses/mines—500Nm torque handles loaded pallets; IP55 rating resists dust and water in outdoor yards.
  • Goods Elevators: Powers elevator lift mechanisms—reversible rotation enables up/down movement; continuous duty (S1) supports frequent operation in logistics centers.
• Manufacturing & Assembly: Production line machinery:
  • Assembly Line Conveyors: Drives 4.0kW roller conveyors for automotive parts—variable speed (via VFD) matches production pacing; low noise (<75dB) suits factory floor environments.
  • Mixers & Agitators: Powers industrial mixers for chemicals/paint—high torque (500Nm) handles viscous materials; cast iron housing resists chemical splashes.
• Food & Beverage Processing: Sanitary and heavy-duty equipment:
  • Bottling Lines: Drives bottle capping and labeling machines—precise speed control (75rpm) ensures consistent product quality; IP55 rating withstands periodic washdowns.
  • Meat Processing Conveyors: Powers stainless steel conveyors—anti-corrosion coating resists cleaning chemicals; continuous duty supports 24/7 processing cycles.
• Construction & Heavy Industry: Site machinery:
  • Crane Hoists: Drives small crane lifting mechanisms—peak torque (1000Nm) handles load startup; durable gears withstand intermittent heavy loads.
  • Concrete Mixers: Powers drum rotation in small concrete mixers—high torque handles thick concrete; rugged housing resists construction site debris.

4. Precautions

• Load Matching (Critical): Ensure the application’s continuous torque does not exceed 500Nm (or 1000Nm peak for 10s)—overloading causes gear tooth damage or motor burnout; use ABB’s torque-calculation tool to verify compatibility with the load (e.g., conveyor weight, mixer viscosity).
• Installation & Alignment:
  • Shaft Alignment: Align the output shaft precisely with the driven load (max misalignment: 0.1mm radial, 0.5° angular)—poor alignment increases bearing/gear wear by 300%; use laser alignment tools for critical applications.
  • Mounting Securely: Bolt the unit to a rigid, vibration-damped base using M12 bolts (torque to 50Nm)—loose mounting amplifies vibration, causing gear loosening and noise; use shims if base is uneven.
  • Rotation Direction: Verify rotation direction before full operation—reverse rotation (if unintended) may damage the load (e.g., elevator cables); test with a temporary power supply first.
• Operation & Maintenance:
  • Lubrication Check: Inspect gear oil level every 6 months (via sight glass)—low oil causes gear overheating; do not mix oil types (use only ABB-recommended synthetic gear oil).
  • Thermal Protection: Do not bypass the PTC thermistor—disabling protection risks motor burnout during overloads; reset only after identifying and resolving the overheating cause (e.g., blocked cooling, excessive load).
  • 定期检查: Perform annual inspections for:
    • Gear Wear: Check for abnormal noise (rattling/grinding) or oil discoloration (metal particles)—indicates gear damage; replace gears if wear exceeds 10% of tooth thickness.
    • Bearing Condition: Measure bearing temperature (max 80℃ above ambient)—overheating indicates bearing failure; replace bearings if vibration exceeds 15m/s².
    • Seals & Housing: Inspect for oil leaks or corrosion—damaged seals allow contamination; touch up anti-corrosion coating if chipped (especially in wet environments).
