Core Transmission Component

1. Core Functions

• Speed Reduction & Torque Amplification
  Decreases motor speed (typically 1440-2900 rpm) to mixing-optimized low speed (~15-30 rpm), while generating sufficient torque to overcome concrete mixing resistance.
• Smooth Power Transmission
  Utilizes gear meshing or worm-wheel mechanisms to minimize drive shock, ensuring stable mixing and protecting against load fluctuations.

2. Critical Roles

• Power Matching
  Converts motor torque into high-output torque required for mixing blades to handle viscous concrete.
• Motor Protection
  Absorbs operational loads to prevent motor burnout from overload/lock-rotor conditions, extending motor lifespan.
• Precision Speed Control
  Maintains consistent mixing speed to ensure concrete uniformity (slump, workability).

3. Common Types

• Gear Reducers
  • Hardened gear (heavy-duty applications)
  • Planetary gear (compact design, >95% efficiency)
• Worm Gear Reducers
  • Self-locking function (safety against reverse rotation)
  • Low-noise operation (slightly lower efficiency than gear types)

4. Application Scenarios

• Forced Mixers: Require high-torque reducers for horizontal/vertical shafts.
• Drum Mixers: Prefer worm gear reducers for rotation-lock safety.

5. Maintenance Essentials

• Lubrication: Use specified viscosity oil to minimize gear wear.
• Seal Inspection: Prevent concrete ingress into bearings/gears.
• Temperature Monitoring: Abnormal heat indicates overload or lubrication failure.

Conclusion

Reducers directly determine mixer reliability, energy efficiency, and concrete quality. Selection criteria must align with mixing capacity, torque requirements, and operating environment (outdoor/high-temperature). Proper maintenance can significantly extend equipment service life while reducing failure rates.
