ML(LM) Plum Blossom Shaft Coupling Keyway Spider Jaw Coupler

It achieves strong buffering and vibration absorption with ‌ high torsional flexibility ‌ and ‌ hysteresis damping characteristics ‌, and is particularly good at reducing impact loads. Its elastomer compensates for radial/angular deviations through ‌ winding deformation ‌, and the pre-compression design ensures zero backlash torque transmission. It is suitable for frequently start-stop ‌ heavy-load impact scenarios ‌ (such as crushers and compressors). The elastic pad is maintenance-free and quick to disassemble and replace. It provides ‌ overload protection ‌ and ‌ electrical insulation ‌ for equipment in an environment ranging from -40℃ to 120℃, making it a flexible hub for heavy industrial power.

1. Strong buffering and shock resistance

The ‌ plum blossom-shaped elastic pad ‌ (rubber/polyurethane) is deformed through ‌ bending to absorb high-frequency vibration, and can withstand instantaneous overload of over 200%. It is especially suitable for high-impact load scenarios such as crushers and presses.

2. Zero backlash precise transmission

The pre-compression design of the elastomer eliminates transmission clearance, ensuring the continuous and stable transmission of ‌ torque ‌ and avoiding reverse impact during start-stop.

3. Triple safety protection

Overload protection ‌ (priority protection equipment for elastic pad breakage) + ‌ electrical insulation ‌ (resistance value > 500MΩ) + ‌ temperature self-adaptation ‌ (stable performance from -35℃ to 80℃).

4.maintenance cost is extremely low

Elastic pad quick-release design ‌ : Replacement can be completed within 10 minutes without disassembling the main equipment or moving the motor, significantly reducing downtime losses.

Lubrication-free and maintenance-free ‌ : fully enclosed structure dust-proof and water-proof, with a lifespan of over 20,000 hours (under normal working conditions).

5.is highly adaptable

Compensate for ‌ radial deviation ≤5mm‌ + ‌ angular deviation ≤5°‌, allow installation centering error, and reduce installation accuracy requirements.

6.economical and efficient

The elastomer accounts for 70% of the cost. When replacing, only the consumables (elastic pads) need to be replaced, and the service life of the main metal parts exceeds 10 years.
