About this product

Product information from the supplier.

The ML(LM) Plum Blossom Shaft Coupling is a high-performance industrial power transmission solution engineered for heavy-load environments. By leveraging a unique plum blossom-shaped elastomer, this coupling provides exceptional torsional flexibility and hysteresis damping, making it the ideal choice for mitigating impact loads and absorbing high-frequency vibrations in critical machinery.

Designed for reliability in extreme conditions, the ML Series features a pre-compression mechanism that ensures zero-backlash torque transmission. Whether operating in crushers, compressors, or presses, this coupling provides a flexible yet stable hub that compensates for radial and angular deviations while offering integrated overload protection and electrical insulation.

Detailed Parameters

Operating Temperature	-40℃ to 120℃	Insulation Resistance	> 500MΩ
Radial Deviation	≤ 5mm	Angular Deviation	≤ 5°
Overload Capacity	Over 200%	Service Life	> 20,000 Hours
Backlash	Zero Backlash	Replacement Time	Within 10 Minutes
Elastomer Material	Rubber/Polyurethane	Metal Parts Life	Over 10 Years

Key Advantages

Shock Absorption

High-frequency vibration absorption via bending deformation of the plum blossom pad, ideal for high-impact loads.

Zero Backlash

Pre-compression design eliminates transmission clearance for stable torque delivery during start-stop cycles.

Triple Protection

Combines overload protection, electrical insulation (>500MΩ), and extreme temperature adaptation.

Rapid Maintenance

Quick-release design allows pad replacement in 10 minutes without moving the motor or main equipment.

High Adaptability

Compensates for radial and angular deviations, significantly reducing installation centering requirements.

Cost Efficiency

Long-life metal components (10+ years) mean only the inexpensive elastic pads require periodic replacement.

Frequently Asked Questions

Q: What makes the Plum Blossom coupling better for crushers and compressors?

These machines experience frequent start-stop cycles and heavy impact loads. The ML Series utilizes a plum-blossom shaped elastomer that absorbs high-frequency vibrations and handles over 200% instantaneous overload, protecting the motor and drivetrain.

Q: How does the "zero backlash" feature benefit my operation?

The pre-compression design of the elastomer eliminates any gap between components. This ensures that torque is transmitted immediately and continuously, preventing reverse impact and wear during frequent reversals or start-stop sequences.

Q: Is the ML coupling really maintenance-free?

Yes, it is lubrication-free. The fully enclosed structure is dust-proof and waterproof, meaning you don't need to grease it. Maintenance is limited only to the periodic replacement of the elastic pads.

Q: What is the electrical insulation benefit of this coupling?

With a resistance value exceeding 500MΩ, the coupling acts as an electrical insulator between the driver and the driven equipment, protecting sensitive components from stray currents or electrical faults.

Q: How does this coupling handle misalignment?

The winding deformation of the elastomer allows the coupling to compensate for radial deviations up to 5mm and angular deviations up to 5°, which simplifies installation and reduces the stress on bearings.

Q: Why is it more economical than other shaft couplings?

The main metal parts are designed for a 10+ year lifespan. Since the elastomer represents the primary wear part and is inexpensive and quick to replace, your long-term OpEx is significantly lower than replacing entire units.
