Pulley balancing

Balancing drive pulleys is critical because it eliminates destructive cantilever vibration and belt oscillation at high speeds, preventing motor bearing failure, uneven belt wear, and premature breakage or slippage of the drive belts.

This series of machines can be used to balance such parts

Pulley types requiring professional balancing:
  • V-Belt Pulleys and Poly-V Pulleys
  • Timing Pulleys
  • Flat Belt Drive Pulleys
  • Flywheel Pulleys
  • Variable Speed Pulleys
  • Clutch Pulleys

Eliminating Belt Drive Problems Through Precision Pulley Balancing

VTM balancing stops vibration-induced belt wear, bearing failures, and alignment issues that compromise drive system reliability and efficiency.

Specific Feature
Lack of integral support collars

Pulleys often do not have their own shaft, so special balancing mandrels must be used to mount them on a balancing machine.

Specific Feature
Cantilevered mass distribution

When mounted on a mandrel, the pulley is often positioned behind the machine’s supports, which creates a risk of tipping and requires the use of radial supports to ensure safety and accuracy.

Specific Feature
Closely spaced correction planes

Because of the pulley’s small axial width, its correction planes are very close together, making it difficult to separate the static and torque components of the imbalance.

Specific Feature
Limited availability for treatment

The pulley’s design often allows mass to be removed or added only in specific areas, which requires the measurement system to calculate imbalance at points dictated by the design.

Other options required for balancing pulley
  • Balancing mandrels
  • Mandrel Eccentricity Compensation Function
  • Static and dynamic balancing
  • Calculation of imbalance at design-determined points
  • Conversion of unbalanced mass to drilling depth
