Large Size Rotor Rubber Rollers Universal Joint Drive Dynamic Balancing Machine

1. Product Description
This YYW Series (7500-20000KG) balancing machine is applicable for the balance measurement of various workpieces, such as mwind turbines, large motors, water pumps, centrifuges, rubber rollers,  internal combustion engines, sieve baskets and other rotating parts where the outer circle cannot be driven by a belt drive or where a high transmission torque is required.

2. Main Features:
1. Professional design of the swingframe, effective transfer of mechanical force, solid and reliable, low vibration resistance, good rigidity.
2. High sensitivity sensor, good linearity, durable and reliable.
3. Once calibrated, permanently used, allowing high initial unbalance.
4. Special universal coupling drive for balancing machine, smooth power transmission, quick start, easy to operate.
5. Suitable for products where the outer circle cannot be turned with a belt drive or where a large drive power is required.
6. advanced electrical measuring system, friendly human-machine interface, complete functions.
