- inter-support and cantilever rotors (armatures, pumps, turbine rotors)
- rotors on special mandrels (smoke pumps, fans, pulleys, impellers)
- rotor in own bearings (rollers, rollers)
The balancing machine 9D717 is used to balance rotors of various structures at repair and production plants. Thanks to narrow stands and the ability to install a combined rotation drive for various technological methods.
The 9D717 model machine has a simple, but rather reliable and functional design, which allows you to easily balance the anchors of electric motors of all types, generator rotors and balance parts such as beaters and fan wheels even if they have a large initial imbalance.
Having the necessary equipment, it is also possible to balance the rotors in their own bearings, which greatly reduces the repair time since replacing the bearings can create many problems and cause damage to the trunnions of the rotor. In this way, it is convenient to detect and eliminate imbalances on motor rotors, drums, rolls of metallurgical gears, as well as screw shafts and shafts of printing equipment.
The machine has a high degree of versatility, which allows balancing disk-type parts, such as impellers and working wheels of smoke pumps, and eliminating imbalances on shaft-type parts, for example: threshing drums or combine rotor. Assemblies such as pumps and blowers often need to be balanced after repair or due to wear of working planes during operation and a balancing machine of the 9D717 series does well in balancing these rotors.

ADVANTAGES AND FEATURES
High balancing accuracy
High balancing accuracy
- Special design of rollers, high-precision bearings are used in their assembly, and complex, patented "exact barrel" ® grinding technology is used.
- The monolithic design of supports and frames prevents vibration loss during balancing by reducing the number of elements of the "oscillating system."
- High precision sensors sense even the micro-vibration coming from the rotor.
Usability
- Allows you to measure huge imbalances without destroying the machine, as well as to correct the rotor imbalance directly on the machine.
- Low own "resonant frequency" of the supports allows balancing the rotor at low rpm
- The width of the "support rollers" and the "roller cassette" allows you to install a rotor with a very small length of the rotor support necks.
- The height of location "roller cassettes" makes it possible to install products with large overall dimensions, and the modular design allows you to increase the standard dimensions of the machine due to spacers and tooling.
- The support has the possibility of adjusting the "roller block" in height, this allows balancing the rotor with different diameter of the support necks, and also allows centering the rotor during adjustment of the machine.
- The unique micro-tuning mechanism ® technology eliminates the "thread" effect (when the rotor moves axially).
- Supports are positioned relatively to the frame by means of a chain mechanical drive, this simplifies the adjustment process.
- The special design of the supports allows you to install the rotor without paying attention at its length, the limitation is only the width of the "drive belt" or the length of the bed. (By special order, the bed can be made for a rotor of any length).
- "Belt drive" has a patented "LONG STROKE" ® design, which allows to balance any rotor with only two drive belts.
- The electric motor has a power margin, which reduces the acceleration and braking time of the detail.
- The electric drive is equipped with a frequency converter, it provides reliable protection of all electrical equipment and allows you to organize smooth acceleration and braking of the electric motor, as well as to perform stepless control of the rotor speed.
Machine design
- An alternative to the "belt drive" is "axial drive," which uses a cardan shaft that is able to transmit high torque from the motor to the rotor. Such a drive is used for details having high aerodynamic resistance or design features (for example, screws). The axial drive of all the machine tools of the 9D series is equipped with a full-fledged tailstock.
- Combined drive - both axial and belt drives on one frame. Such a machine will be in demand by enterprises with various rotors in design.
- Drill module to eliminate rotor imbalance without its removing from the machine. It is comfortable to use it to increase the operation performance.
BALANCING SYSTEM AND CONTROL
We make balancing easier - the main advantage characterizing our balancing systems.- Ease of use and ease of operation do not require special theoretical knowledge from the operator.
- Displays the real-time balancing process, monitors the rotor imbalance behavior on the screen to achieve the best result.
- The maximum sensitivity of the machine at any moment of operation, adjustment to the rotor and calibration of the machine is carried out by the operator himself.
- Free of the influence of external vibration factors on the measurement result, has a high level of noise immunity of all elements.
- World-leading functionality and accuracy thanks to 40 years of industry development and application experience.
