Why Rotor Balancing of Mulchers is Necessary

Rotor balancing of mulchers is essential not only for reducing vibration and noise during operation but also for preventing premature wear of bearings, reducing the load on the drive, and extending the overall lifespan of the machine. Using a portable balancer allows for onsite balancing without the need to dismantle the mulcher and remove the rotor.

Preparation for Balancing

Before starting the balancing process, it is necessary to conduct a thorough inspection of the mulcher. It is important to check the bearings for play, inspect the housing for cracks, and ensure that all bolted connections are properly tightened. It is also recommended to either weld the push frame and front curtain to the mulcher body or remove them to prevent possible interference with the balancing process.

Balancing Process

To balance the rotor of a mulcher with the portable balancer Balanset-1A, follow these steps:

  1. Place the vibration sensors perpendicular to the rotor’s axis of rotation and the tachometer on a magnetic stand. Apply reflective tape to the pulley or rotor, directing the rotation sensor towards it.
  2. Connect the sensors to the Balanset balancer, and then connect it to a laptop.
  3. Launch the software, select two-plane balancing, and enter the rotor data.
  4. Measure the weight and the mounting radius of the calibration weight, and enter these data into the software.
  5. Start the rotor to measure the initial vibration level.
  6. Place the calibration weight in the first plane, aligning it with the first sensor’s position, and take a measurement. Then, move the weight to the second plane, where the second sensor is located, and repeat the measurement.
  7. The software analyzes the data and suggests how much weight and at what angle to install the corrective weights for both planes.
  8. Remove the calibration weight and install the corrective weights according to the software’s recommendations.
  9. Perform a final rotor spin to check the success of the balancing. Make further adjustments as recommended by the software if necessary.

This approach allows for precise balancing of the mulcher rotor, reducing vibration, and optimizing equipment operation.

Detailed Overview of the Standard Delivery Set of Balanset-1A, Our Most Popular Product

The standard delivery set includes:

  • Control Interface Unit: Acts as the “brain” of the device, processing signals from sensors and controlling the balancing process. The interface unit is housed in a durable case and equipped with necessary ports for connecting sensors and external devices.
  • Vibration Sensors: Two vibration sensors included in the set are designed for accurate measurement of the rotor’s vibrational parameters. These sensors are highly sensitive, ensuring precise readings even at minimal vibrations.
  • Optical Sensor (Laser Tachometer): Used for measuring the rotor’s rotation frequency. The laser type sensor ensures high measurement accuracy and ease of use due to its contactless data reading method.
  • Magnetic Stand for Optical Sensor: Designed for secure mounting and precise adjustment of the optical sensor’s position relative to the rotor.
  • Electronic Scales: Necessary for accurately weighing corrective weights before their installation on the rotor. The accuracy of the scales is crucial for quality balancing.
  • Software: Specialized software provides an intuitive interface for entering balancing parameters, analyzing the received data, and calculating the optimal placement of corrective weights.
  • Transportation Case: A sturdy case is provided for convenient transportation and storage of the set, protecting the equipment from damage and external influences.
