SEMI-AUTOMATIC DRIVE SHAFTS BALANCING MACHINE BVI-03-78
Special, with automatic clamping of cardan flanges, with several welding stations, with PAK-4 balancing system. The machine is designed for balancing in serial production of various two- and three-four-bearing cardan shafts, up to 4200 mm long and weighing from 3 to 150 kg.
Design features
Balancing accuracy 5 gmm/kg. The cycle of measuring the imbalance of the cardan shaft is carried out automatically simultaneously in 4 (2 or 3) correction planes. Estimated cycle time for measuring imbalance, taking into account the time of acceleration and deceleration of the cardan shaft, is 11 … 25 seconds. The movable spindle support is equipped with its own movement mechanism on ball guides to provide auxiliary movement when installing and removing the cardan shaft. The adjusting movement of the support together with the movement mechanism along the frame provides the possibility of installing 3- and 4-support cardan shafts of any design on the machine within the overall dimensions of the shaft.
The method of eliminating the imbalance is by welding corrective weights (plates) by contact welding. Welding tongs are installed on the machine in an amount corresponding to the number of correction points (specified in the statement of work).
It is possible to supply the machine with universal cam clamping adapters with manual clamping. The left spindle support is stationary, driven; the right spindle support and intermediate supports are movable.
The fastening of the cardan shaft flanges in the adapters is carried out automatically by pneumo-mechanical chucks. The clamping chuck provides basing and reliable clamping of cardan shafts with flange sizes in the range up to 125 mm. For each flange size, a centering adapter is made according to the specification. Asynchronous frequency-controlled electric drive allows you to perform stepless speed control without stopping the electric motor, the choice of optimal modes for balancing, and also to turn additionally the cardan to the place of welding of the balancing plate. The rotation of the cardan shaft to the place of welding of correction weights for each plane is performed automatically by pressing the button on the corresponding support. To ensure safe working conditions, the machine is equipped with: – protective brackets with a pneumatic drive – to prevent the shaft and its elements from flying out when the hinges or spline connections are destroyed – blocking the inclusion of spindle rotation when they are fixed and when the welding tongs are extended. The machine is equipped with a sectional protective guard of the cardan shaft to protect against probable ejection, when the shaft rotates, poorly fixed corrective weights, grease from bearings, etc. The guard is equipped with a blocking of the spindle rotation when the guard is not closed.

To ensure safe working conditions, the machine is equipped with: protective brackets with a pneumatic drive – to prevent the shaft and its elements from flying out when the hinges or spline connections are destroyed. Blocking the inclusion of spindle rotation during their fixation and when extending the welding tongs. The machine is equipped with: a sectional protective guard of the cardan shaft, to protect from probable ejection, when the shaft rotates, poorly fixed corrective weights, grease from bearings, etc. The guard is equipped with a lock of turning on the rotation of the spindle when the guard is not closed.
BALANCING SYSTEM AND CONTROL
We make balancing easier – the main advantage characterizing our balancing systems.
- Ease of use and simple operation do not require special theoretical knowledge from the operator.
- Displays the balancing process in real time and monitors the unbalance behavior of the rotor on the screen to achieve the best possible result.
- The maximum sensitivity of the machine at any moment of operation, set-up and calibration of the machine is carried out by the operator himself.
- Free from the influence of external vibration factors on the measuring result, has a high degree of protection against various types of disturbance.
- World-leading functionality and accuracy due to 40 years of industry development and application experience.
