The Mixer Truck Mixer Drum Reducer Flange is the high-torque output flange that rigidly connects the planetary reducer (gearbox) to the mixing drum, transmitting rotational drive while accommodating limited angular misalignment.
Product Parameter
Product Feature
1)Forged Construction - High-strength forged body for superior durability and impact resistance under heavy torque loads.
2)High-Quality Material - Typically made from Q235, Q345B, or equivalent carbon steel with hardness 17–20 HRC for balanced strength and toughness.
3)Bolt Pattern - Standard 24-bolt circle (or customizable), ensuring secure, rigid connection to the drum.
4)Thread Specifications - Common bolt threads M16×1.5mm or M16×2mm for reliable fastening.
5)Misalignment Tolerance - Allows ±6° (or similar) angular misalignment to accommodate drum tilt, road vibrations, and installation variations.
6)Wear & Abrasion Resistance - Surface hardened or treated to resist concrete splatter, corrosion, and mechanical wear.
7)Precise Machining - Tight tolerances for perfect alignment, reducing vibration, noise, and premature failure.
8)Compatibility - Designed as universal replacement for major reducers like PMP (PMB7.1, PMB6.5), ZF (PLM7/9), Bonfiglioli, Sauer-Danfoss (TMG series), etc.
9)Easy Installation & Maintenance - Bolt-on design; often includes sealing surfaces or O-ring grooves for leak prevention.

FAQ
Q：What materials are typically used for this flange?
A:High-strength steel like Q235, Q345B, or forged alloy steel with hardness around 17–20 HRC.
Q:How many bolts does a standard reducer flange have?
A:Most common is 24-bolt pattern; some models use 20 or custom configurations.
Q:How do I know when to replace the reducer flange?
A:When there is excessive wear, cracking, bolt hole elongation, leakage around the connection, or vibration/noise increase.
Q:What torque should be applied to the flange bolts?
A:Depends on bolt size (e.g., M16 usually 200–300 Nm); always follow reducer manufacturer's torque specs and use thread locker.
