Home Products Raw Edge Cogged V-Belt

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

  • Brand :

    Zhongliang, Liannong, Agreap, Rnupower, JDRE
  • Item No :

    AX, BX, CX, DX, ZX, AV
  • Certificate :

    ISO9001, ISO14001, ISO45001 and ISO50001
  • Payment :

    100% T/T before delivery
  • Product Origin :

    China
  • Shipping Port :

    Any port in domestic of China
  • Lead Time :

    15-45 working days

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

Parameter Toothed V belt Classical Wrapped V belt
Bending Flexibility 50% higher Baseline
Heat Dissipation 30% improvement Limited
Efficiency 98% 92-95%
Minimum Pulley ∅ 30% smaller Restricted by stiffness

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)


Failure Mode Analysis

Symptom Root Cause Solution
Cog root cracking Over-tensioning Use sonic tension gauge
Cord SEPARATION Pulley misalignment Realign drives
Rapid wear Under-sized pulley Replace sheave
