YYQ-8000A Belt Drive Balancing Machine 8000kg Max Workpiece Industrial Rotor Dynamic Balancing Tester

Product Overview

The YYQ-8000A is a universal hard-supported dynamic balancing machine designed and manufactured in strict accordance with GB/T4201-2006. It is engineered for high-capacity rotor balancing of large and heavy rotating components used in motors, fans, pumps, papermaking rolls, marine propellers, turbomachinery and heavy industrial machinery.

The machine adopts roller-supported workpieces, ring-belt (circle drag) drive and an industrial-control computer for data processing. A 19-inch LCD displays imbalance, phase angle and real-time speed in real time. The bundled GB-2000 general-purpose microcomputer balance measurement system runs on Windows with a fully automatic program-controlled amplification module, making operation simple and intuitive.

Key Features

• Double-sided dynamic balancing machine that drives the workpiece by ring belt; supports both double-sided and single-sided balancing.
• Handles workpieces from 80 to 8000 kg with diameters up to 2600 mm and effective lengths from 300 to 5600 mm.
• Two 3-meter-long beds made from HT250 integral casting with T-shaped parallel guide rails machined and ground by a large gantry milling machine, ensuring flatness and overall mechanical accuracy.
• Swing frame integrally cast from nodular cast iron QT450 - better performance than welded or bolted elastic-beam designs; delivers higher rigidity and natural frequency for long service life.
• Split swing frame can be moved manually along the bed and stopped at any position, giving an effective balancing length between 300 and 5600 mm.
• Rollers are made from GCr15 bearing steel, high-frequency quenched to above HRC55, ground and demagnetized. RZ5 precision bearings ensure wide-line contact with the workpiece for accurate measurement and long roller life.
• Left and right safety guards with reverse rollers to press the workpiece and prevent unstable running caused by excessive unbalance.
• 15 kW inverter-driven motor for soft start and stop, extending the service life of the equipment.
• High-precision piezoelectric vibration sensor and photoelectric diffuse-reflection speed sensor.
• Frequency-conversion speed regulation system, continuous-duty design, simple maintenance, pollution-free pure electrical drive.
