YYQ-100 Hard-Bearing Balancing Machine (Belt Drive)

YYQ-100

Horizontal Balancing Machine

Hard-bearing balancing machine (belt drive) for workpiece with diameter of up to 900mm and weight of 3-100kg

  • Belt driven hard-bearing balancing machines for medium and small motor rotors as well as a variety of other rotating parts.
  • The belt drive avoids the interference that rigid couplings can create on the rotor, ensuring more accurate results.
  • Handles workpieces with a maximum diameter of 900 mm and a support length of over 1000 mm.
Applications

Used for balancing motor rotors, fan impellers, turbocharger rotors, crankshafts, and machine tool spindles. It is also suitable for long roller parts in paper-making and printing machinery.

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.

The frequency depends on usage intensity and operating environment. In most cases, calibration is recommended to calibrate balancing machines once a year, but for machines running under heavy workloads or harsher conditions, more frequent checks are advised to maintain precision.

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.
