WHEELSET BALANCING MACHINE

The VTM GROUP company commercially produces two models of machines for balancing wheel sets of rolling stock: 9717K and 9718K. Load capacity, kg: 100-1500 and 300-3000 (4000 *), respectively. 9717K is focused on the wheel sets of passenger cars. 9718K is designed for traction stock wheelsets, but can also be used for wagon wheelsets. The machine has a high accuracy of determining the imbalance of the rotor (0.5 kg∙cm).

1. The balancing system provides measurement of unbalance in the polar coordinate system in two planes with display of the magnitude and angle of unbalance, both relative to the axis passing through the geometric centers of wheel rolling, and relative to the axis of rotation of the wheelset in axle bearings.
2. The PAK-GD balancing system is tuned using the “three starts” method, the advantage of this method is that the equipment always has a high sensitivity, since the machine calibration procedure is carried out each time it is tuned to a new rotor.
3. The processing and output of information takes place in the "real time" mode, which allows you to track the behavior of the imbalance, improving the analysis of information.
4. For the convenience of controlling the balancing system, the equipment is fitted up with an industrial computer with a touch screen running on the Windows 7 operating system.
5. The balancing system of the machine allows you to work with two correction planes at once, which significantly reduces the balancing time.
6. The software interface has many hints to help you quickly master the controls.
7. When designing the interface, diagrams were used to simplify the analysis of information.
8. The lever design of the movable suspension of the supports makes it possible to achieve high accuracy of the machines at a speed of 200 ... 400 rpm and allows the operator to analyze the residual level of imbalance in visual way.
9. The machines are equipped with "jacks", which allow you to achieve a quick shock-free installation of the rotor, this allows you to save the support necks of the wheelset and the support rollers of the machine.
10. Quick installation of the rotor is also achieved through the use of catchers in the design of the jacks, while the wheelset is centered automatically.
11. The machine can be fitted up with special additional equipment for balancing wheel sets with a gearbox (driven from the middle part of the axle) without dismantling the gearbox.
12. The special design of the “support rollers” and high-quality high-precision bearings, as well as a special technology for the production of rollers, make it possible to achieve high accuracy.
13. The “roller block” has a “self-installation” function, which eliminates the need for its adjustment, which reduces installation time, and also eliminates the possibility of “knurling” on the rotor bearing journals.
14. The width of the support rollers also prevent the appearance of "knurling" on the contact surface of the rotor.
15. The machine can be equipped with additional milling devices to eliminate imbalance.
16. The equipment is fitted up with an “axial drive”, its feature is that it is able to transmit a large torque, which allows you to accelerate and stop the wheelset quickly, this makes it possible to shorten the balancing cycle. The presence of a full-fledged spindle with a quill increases the productivity and reliability of the machine.
17. The electric motor has a power reserve, this allows you to reduce the acceleration and deceleration time of the rotor, as well as increase its resource.
18. The design of the electric drive has a frequency converter, it protects the electrical equipment and allows smooth acceleration and deceleration of the electric motor and stepless regulation of the rotor speed.
19. Rolling stock wheel pair balancing machines have high reliability and productivity. Which is confirmed by the actual operation of such a machine in the conditions of mass production (PJSC INTERPIPE, Dnepropetrovsk).
