    Portable Field Balancer

    Portable field balancing tool with touch screen for single-plane and two-plane rotor balancing at rotational speed up to 5000r/min

    These portable field balancers with touch-screen operation combine a portable computer platform with LABview programming software from National Semiconductor, creating a flexible and efficient rotor balancing system. The modular and easy-to-use design allows both single-plane and two-plane balancing to be performed within the same system, so different balancing needs can be handled without switching between setups. This makes them adaptable for a wide range of on-site applications where different types of rotating components require specific balancing solutions.

    Applications

    Mainly used for balancing fans, motors, machine tool spindles, pumps, grinding wheels, and other rotating machinery on-site.

    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.

    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.
