YYQ-30 Hard-Bearing Balancing Machine (Belt Drive)

YYQ-30

Horizontal Balancing Machine

Hard-bearing balancing machine (belt drive) for workpiece with diameter of up to 800mm and weight of 2-30kg

  • Hard-bearing balancing machine combined with frequency converter speed control for flexible adjustment
  • Balancing speed can be matched to the actual operating speed of the rotor or component
  • Smooth and safe operation without interference from universal joint transmission
  • Reduced influence of shaft bending on long rotors, ensuring higher accuracy
Applications

Suitable for balancing multistage pump rotors and single impellers. It is also suitable for motor rotors, long-shaft parts such as separator and oil press rotors, rollers, and paperboard machine rotors, as well as agricultural machinery components like crushers, straw return machines, and corn harvesters.

Balancing machines are instruments that indicate if a rotating component, such as a rotor or fan, rotates in an unbalanced manner. If the component wobbles or vibrates a lot, the balancing machine will point out the imbalance so it can be corrected. The importance of balancing is directly related to the longevity of the rotating component and how well the component functions.

Soft-bearing machines use flexible supports, making them sensitive to very small vibrations and suitable for lighter or smaller parts that require high accuracy. Hard-bearing balancing machines, on the other hand, use more rigid supports, so they are more suitable for larger and heavier rotors. Hard bearing balancing equipment may be less sensitive to tiny vibrations, but they are easier to set up and give reliable results across a wider range of workpieces.

Balancing machines are used to rotating parts such as motor rotors, impellers, fans, flywheels, clutches, gears, pulleys, and brake drums. By correcting unbalance, they help reduce vibration, extend service life, and keep production running more smoothly.

Balancing machines can be configured with belt drive, universal joint drive, or self-drive. Belt drive is usually chosen for smaller rotors that require accuracy, while universal joint drive delivers higher torque and is safer for heavier parts. Self-drive designs are used when the workpiece can rotate under its own power.

Every wear tester goes through careful calibration and inspection in line with standards like ISO 9001. This step makes sure the measuring accuracy is verified and consistent before the tester is shipped out to clients.
