Accuracy, g.mm/kg

The machine for balancing a wide range of rotors weighing up to 300 kg. Universal, pre-resonant, with horizontal axis of rotation. On such a machine it is possible to balance

  • inter-support and cantilever rotors (armatures, pumps, turbines, crankshafts)
  • rotors on special mandrels (disks, fans, pulleys, impellers)
  • rotors in own bearings (rollers, drums)

Thanks to the narrow struts and the belt drive, the balancing machine 9D715U is used for the balancing of rotors of various structures at repair and production plants.

We offer complex solution on details balancing, but not only sell the machines.

Together with the machine You will obtain the balancing technology, trainings on operation experience as well as the technical support during all the service term.

    Benefits and Features

    Высокая точность балансировки 0,4гмм/кг = 0,4мкм

    • The monolithic design of supports and frames prevents vibration loss during balancing by reducing the number of elements of the “oscillating system.”
    • Special design of rollers, high-precision bearings are used in their assembly, and complex, patented “act barrel” ® grinding technology is used.
    • 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 correct the rotor imbalance directly on the machine.
    • Low natural “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 of the “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 relative 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, with only two drive belts, to balance any rotor.
    • The electric motor has a power margin, which reduces the acceleration and braking time of the part.
    • 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 perform stepless control of the rotor speed.

    Machine design

    • An alternative to the “belt drive” is the “axial drive,” which uses a cardan shaft that is capable of transmitting high torque from the motor to the rotor. Such a drive is used for parts having high aerodynamic resistance or design features (for example, screws). The axial drive of all 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 for elimination the rotor imbalance without removing from the machine. Conveniently used to increase the performance of an operation.

    Machines have many unique technical solutions that allow you to adjust and balance complex rotors as soon as possible, without losing the accuracy of determining imbalance.

    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 time 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.
