    Drive Shaft Balancing Machine

    Hard-bearing balancing machine for dynamic balancing of drive shafts

    The YRD-100A is a hard-bearing balancing machine for automotive drive shafts. With its three-pedestal design, it supports both two-plane and three-plane dynamic balancing, offering flexibility for different shaft types and configurations. When operating in three-plane mode, the drive shaft balancing machine simultaneously displays correction data for all three planes, eliminating the need to repeatedly switch pedestal sensors. This greatly improves efficiency and convenience, making it suitable for both drive shaft manufacturing plants and the automotive repair industry.

    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.

    Accuracy may be affected by operator handling, incorrect markings, or mismatched correction points. Technical issues such as damaged sensors, loose connections, or electronic failures can also play a role. Regular calibration and proper setup help keep results consistent.
