AX BX CX DX ZX AV Classical Cogged V belt or Toothed V belt

Applications:

1. Agricultural Machinery:

• Combine harvesters (Thresher drives,reel drives, cleaning fan systems)
• High-torque implements (Balers, Mowers) 
• Irrigation pumps: Frequent start/stop cycles

2. Industrial Equipment:

• Compressors: Small-diameter sheaves(40% size reduction)
• Conveyors: Reversing drives with frequent tension changes
• Textile Machinery: High-speed looms(1,200-3,000 RPM)

3. Automotive:

• Supercharger Drives
• Racing Engine Accessories: Reduced parasitic power loss

Features:

1. Cog Design:

• Transverse grooves (depth: 1.5–3mm) spaced at 3–8mm intervals

• Reduces bending stress by 40% compared to standard V-belts

2. Reinforcement:

• Aramid/polyester tensile cords (longitudinal)

• ISO 4184-compliant dimensional tolerances

3. Material:

• Oil/heat-resistant chloroprene rubber (-30°C to +90°C)

• Static-dissipative options available (≤10⁶ Ω, ISO 1813)

Advantages VS. Classical V-Belts

Selection Guidelines

1. Power Rating Adjustment

• Toothed belts handle 20% higher power in same section (e.g., Cogged B-section ≈ Standard C-section)

2. Pulley Compatibility

• Requires standard V-groove pulleys (no special sheaves needed)
• Minimum pulley diameter:
• A-section: 67mm → 45mm (toothed)
• B-section: 112mm → 80mm (toothed)

3. Installation Criticals

• Tensioning: 1.6% initial elongation (vs. 2.0% for classical belts)

• Alignment: ≤0.3° angular error (laser alignment recommended)
