The wheel balancing machine WB1105 is a special, above-resonance type balancing machine with axial drive and the balancing system. It is designed for wheelsets of traction rolling stock with mass up to 3,500 kg, maximum diameter 1350 mm, and length up to 2800 mm. It supports wheelsets with gears, brake discs, and axial gearboxes. Balancing is performed according to GOST 11018-2011.

Design Features of the Balancing Machine
• Balancing accuracy: 0.4 gmm/kg
• Self-aligning bearing parts with cylindrical hardened rollers prevent marks on low-hardness rotor journals
• Lever suspender with low natural frequency ensures high precision
• Two roller diameters per cartridge reduce interferences at journal-roller diameter matches
• Adjustable roller supports enable balancing of symmetric and asymmetric journals
• Suspension locking during acceleration/braking allows balancing of heavily imbalanced wheelsets
• Axial drive via articulated adapter mounted to axle end
• Spindle bed simplifies wheelset mounting/removal
• Jacks ensure smooth and safe wheelset handling, protecting mechanisms
• No special foundation required – installation directly on workshop floor
• Variable frequency asynchronous drive for stepless speed control during operation
• Imbalance measured relative to axis through wheel center circles
- 25-second measurement cycle
- Real-time measurement display
- Measures imbalance relative to wheel rolling circles and rotation axis
- Touchscreen interface with fanless industrial PC
- Three-start calibration method using reference rotors
- Real-time visualization of imbalance
- USB, LAN, and Ethernet connectivity
- Automatic averaging for unstable signals
- Eccentricity compensation and vector diagram analysis
- Automatic start/stop in balancing mode
Balancing System Advantages
• Industrial fanless computer with touchscreen and measurement module
• Calibration by operator using three-start method with known unbalanced rotors
• No need for annual paid calibration services
• Calculates allowable unbalance values even without product documentation
• Recommends control weight sizes for easier control
• Real-time visual feedback reveals defects or disturbances immediately
• Displays imbalance in grams, gmm, gcm, gmm/kg, Dadd
• Corrects for eccentricity of balancing mandrel
• Splits imbalance into multiple correction planes
• Allows placement of corrective weights at structurally predefined points
• Generates and prints balancing reports
• USB and Ethernet ports for connectivity and external devices |
