HZX HAX AX HBX BX HCX CX HDX DX HDJX Heavy duty Cogged V belt or Toothed V belt

HZX HAX AX HBX BX HCX CX HDX DX HDJX Heavy duty Cogged V belt or Toothed V belt

Heavy-duty cogged agricultural V-belt is a specialized power transmission belt engineered for extreme operating conditions in farming machinery. It combines cogged inner surface (transverse grooves) for superior flexibility and heat dissipation, reinforced construction with high-strength tensile members and abrasion-resistant covers, agricultural-specific compounds to withstand environmental challenges like dust, moisture, and UV exposure together.

These belts are designed to transmit high torque in applications with shock loads, variable speeds, and continuous operation.

Agricultural Applications:

  • Combine Harvesters: Main threshing drum drives, reel drives

  • Forage Harvesters: Cutterhead drives, feed rollers

  • Tractors: PTO drives for balers, mowers, and sprayers

  • Irrigation Systems: High-torque pump drives

 

Features:

1. Cogged Profile:

  • Internal grooves reduce bending resistance by 40% vs. standard V-belts
  • Allows use with smaller pulleys (↓30% min. diameter)

2. Reinforcement:

  • Aramid/polyester tensile cords (minimal stretch, high strength-to-weight ratio)
  • Multiple cord layers for shock load absorption (e.g., sudden engagement of balers)

3. Cover Material:

  • Oil- & weather-resistant compound (typically chloroprene or EPDM)

  • Anti-aging additives for UV protection (ISO 1431 compliant)

  • Static-dissipative formulation (critical for grain dust environments)

 

Performance Advantages

  • Higher Power Density: Transmit up to 3x more power vs. classical V-belts of same section
  • Extended Service Life: 2,000–3,000 hours in harsh conditions (e.g., combine harvesters)
  • Energy Efficiency: 98% transmission efficiency (vs. 92–94% for standard belts)
  • Temperature Resistance: Operation from -40°C to +100°C without cracking

 

Selection Guidelines

Parameter Heavy-Duty Cogged Belt Standard V Belt
Min. Pulley Ø 60mm (HB-section) 85mm (HB-section)
Power Capacity 15% higher Baseline
Bend Fatigue Life 2X longer Reference
Cost Premium 20-30% -

 

Maintenance Tips

  • Tensioning: Use ultrasonic tension meter (1.5% elongation target)

  • Pulley Inspection: Check for groove wear (max. 0.8mm sidewall deformation)

  • Storage: Keep belts dry and flat (avoid UV exposure before installation)

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

Toothed V-belt (also called cogged V-belt) , is a power transmission belt combining the trapezoidal cross-section of classical V-belts with transverse grooves (cogs) molded into the inner side. These grooves reduce bending resistance, improve flexibility, and enhance heat dissipation while maintaining high torque capacity.
