 ULTRA-ENGINEERING DETAIL: How the L-Type Jaw Coupling Works

The L-Type Jaw Coupling is a torsionally flexible, elastomer-mediated, fail-safe coupling used for mechanical power transmission between rotating shafts.

Below is an ultra-deep engineering breakdown.

1. Mechanical Structure Overview

1.1 Two Metallic Hubs ("Jaws")

Each hub has curved, evenly spaced jaw arms:

• Designed to maximize surface contact area
• Ensure even torque distribution
• Reduce concentrated stress points
• Maintain operation even under uneven load conditions

Materials commonly used:

• High-grade cast iron
• Carbon steel
• S45C or equivalent
• Aluminum (for lightweight systems)

1.2 Elastomer Spider Insert

The “spider” is the heart of vibration damping.

Elastomer options:

• Buna-N (Nitrile): good oil resistance, stable up to ~100°C
• Urethane: higher torque capacity, more resistant to tearing
• Hytrel: high stiffness, chemical resistance, best performance under shock

Spider hardness (Shore A):

• Soft (70A) – better misalignment absorption
• Medium (80A) – balanced performance
• Hard (90A) – higher torque, less damping

1.3 Fail-Safe Redundancy

If the spider fails:

• The jaws make metal-to-metal backup contact
• Machine continues running with reduced vibration damping
• Prevents catastrophic downtime in remote Borneo locations
  (e.g., Kapit, Belaga, Pitas, Lawas)

� ULTRA-DETAIL OF POWER TRANSMISSION

1. Driving hub rotates →
2. Spider compresses slightly →
3. Torque is absorbed, cushioned, and transferred →
4. Spider distributes load across jaws →
5. Driven hub rotates smoothly

Power Transmission Formula (Simplified):

T = (F × r) – Loss(Damping)
Where:

• T = transmitted torque
• F = force from driving shaft
• r = radius of jaw engagement
• Loss(Damping) = vibration absorbed by elastomer

This ensures:
 Low backlash
 Smooth start-up
 Reduced shock loads
 Lower system resonance

 ULTRA-DETAILED PERFORMANCE CHARACTERISTICS

1. Misalignment Absorption

The L-Type coupling compensates for:

This is vital for machines in remote Borneo areas where alignment precision tools may be limited.

2. Vibration Damping Behavior

The spider behaves as a viscoelastic element:

• Absorbs energy during compression
• Releases it slowly
• Reduces harmful vibration frequencies

Benefits:
 Reduced motor bearing wear
 Less noise
 Longer equipment life

3. Shock Load Reduction

During sudden start-up or motor overload:

The spider acts as a mechanical fuse absorbing shock energy.

Perfect for:

• Crushers (Sarawak timber mills)
• Palm oil mill presses
• Reciprocating compressors
• Pump systems in fisheries & marine plants

4. No Lubrication Required (Maintenance-Free)

The elastomer is:

• Self-damping
• Non-metallic
• Resistant to oil, dirt, moisture
• No grease needed → no contamination risk

Ideal for Sabah’s humid & salt-exposed coast (Semporna, Sandakan, Kudat).
