Lárétt Dynamic Balancing Machine

9D717

The 9D717 balancing machine is a versatile and reliable tool for balancing a wide range of rotors from 15 to 1500 kg.
This machine is capable of balancing different types of rotors, including inboard and outboard cantilever rotors, rotors on special mandrels and rotors in their own bearings.

The machine's design is simple yet functional, allowing it to easily balance armatures, generator rotors, impellers and fan wheels, even with large initial imbalances. In addition, the machine can balance rotors in their own bearings, saving repair time and preventing damage to the rotor trunnions.

It is suitable for determining and eliminating unbalance on rotors of electric motors, metallurgical gears, screws and printing equipment.
The 9D717 balancing machine is also capable of balancing disc-type parts such as impellers and smoke pump impellers, as well as correcting unbalance on shaft-type parts such as threshing drums and combine rotors.

Overall, this machine is highly versatile and effective in balancing various types of rotors, making it ideal for repair and production shops.


HIGHLIGHTS
• The specially designed rollers use advanced patented “Exact Barrel” grinding technology and are mounted on precision bearings.
• The monolithic design of the supports and base eliminates vibration losses during balancing by reducing the number of "oscillating system" elements.
• Allows large initial unbalances to be measured without destroying the machine, and rotor unbalance to be corrected directly on the machine.
• The low natural resonance frequency of the supports allows the rotor to be balanced at low speeds.
• The width of the support rollers and roller block allows the installation of rotors with very short rotor bearing journals. The modular design allows rotors with unusual configurations to be mounted using spacers or tools.
• The height of the roller block is adjustable, allowing rotors with different journal diameters to be balanced.
• The belt drive has a patented "Long stroke" design that allows any rotor to be rotated using only two drive belts.
• The frequency converter drive provides smooth acceleration and deceleration of the electric motor and infinitely variable speed control of the rotor.


MEASUREMENT AND CONTROL
• We make balancing easier - the main advantage of our balancing systems.
• The balancing process is displayed in real time and the unbalance behaviour of the rotor is monitored on the screen to achieve the best possible result.
• The maximum sensitivity of the machine at any moment of operation, the set-up and calibration of the machine is carried out by the operator himself.
• Free from the influence of external vibration factors on the measurement result, it has a high degree of protection against various types of interference.
• Easy to learn working skills and maintenance for any employee.
