    HARD-BEARING BALANCING MACHINE WITH BALANCING SYSTEM PAK-1

    UP TO 1500 KG

    9D717 is an universal dynamic balancing machine with horizontal axis of rotation type. Generally, It is possible to balance the following kinds on such a machine:

    • inter-support and cantilever rotors
    • rotor on special mandrels (disks, fans, pumps)
    • rotor in own bearings

    Thanks to the narrow stands and belt drive, the balancing machine 9D717 is used for balancing of rotors of various structures at repair and production plants.

    The machine has high accuracy (0,4 gmm \ kg). Accuracy is achieved due to the special design of the spindle and the rig of the machine, as well as a reliable balancing system, PAK-1, which has a high degree of noise immunity. Ease of control allows you to quickly learn how to work on the machine and get to work as soon as possible. When designing the machine, high demands were placed on the functionality and versatility of each node, this made it possible to install absolutely any driveshaft on the machine with a minimum of time.

    Width of the support rollers and roller cartridges allows the rotor to be installed with a very short length. Highly located “roller cassettes” allow you to create products with different overall dimensions, and the modular design allows you to increase the standard dimensions of the machine due to spacers and accessories.

    Support has the ability to adjust the “roller block” in height, this allows you to balance the rotor with different diameters of the support journals, and also allows you to center the rotor when setting up the machine.

    Design features of the machine

    Generally, every dynamic balancing machine (9D717 in this case) has the unique micro-tuning mechanism ® technology, that eliminates the “thread” effect (when the rotor moves axially).

    Furthermore, the supports are set relative to the bed with a chain mechanical drive, this simplifies the setup process.

    So the special design of the supports allows you to install the rotor without paying attention to its length, the only limitation is the width of the “drive belt” and the length of the bed (By special order, the bed can be made under the rotor of any length).

    The “belt drive” has the patented LONG STROKE ® design which allows with just two drive belts to balance any rotor regardless.

    However, there is an alternative to a “belt drive” is an “axial drive”, which uses a driveshaft that is capable of transmitting large torque from the electric motor to the rotor. Such a drive is used for parts with high aerodynamic drag. In addition, the axial drive of all machines of the 9D series is equipped with a full-fledged quill.

    By special order, it is possible to order a combined version of the machine (with two drives: axial and belt).

    Belt drive also provides versatility of the machine, the large travel of tension pulley allows only one or two belts to be used. Belt installation does not require disassembly of the unit.

    All electrical equipment is located in the cabinet, the outer cables are in metal hose. Nevertheless, the assembly matches CE standards.

    Preconfigured frequency-controlled asynchronous electric drive allows controlling of the rotor speed, as well as acceleration and deceleration process.

    Lastly, safe working conditions on the dynamic balancing machine 9D717 are provided by rigid stops, protective covers of the drive belt and rotating pulleys, safety interlocks, ergonomic controls, etc.

    PAK-1 BALANCING SYSTEM

    Firstly, the digital system is based on an industrial fanless computer with a touch screen and a measuring unit.

    Secondly, set-up mode by “triple start-ups” method with the use of calibration weights on the serial rotors with initial unbalance.

    At last, calibration of the machine is made by the operator enabling to reach the maximum sensitivity of the machine, thus exempting from the duty to pay annual calibration fees.

    Even so, take in consideration following functions:

    • Calculation of the balance tolerance values in default of technical documentation for the balancing product.
    • Value calculation of the correction test weights to simplify the tuning process for the balancing rotor.
    • Real-time balancing display, i.e. if there is any defect or a hindrance of a rotor, it’s visible immediately as fluctuation in measurement result.
    • View of unbalance value in grams, gmm, gsm, gmm / kg optionally.
    • Taking into account the eccentricity of the balancing mandrel.
    • Unbalance distribution on n-planes correction
    • Calculation of hole depth for correction of unbalance.
    • Possibility of decomposition of correcting weights into structurally conditioned anchoring points (blades, fans, slots).
    • Rotor balancing report creating and printing.
    • USB port for printer connection, USB-flash memory, port for connecting to local network and Ethernet network.
