The special electronic control unit manipulates unbalanced drives and can be delivered in servo technology, which gives the advantages of great energy savings and quicker response times. Furthermore the servo drive motors are more robust in a dusty environment because of the closed design without the need of any extra cooling fan, which is needed for 3-phase motors.
interVIB’s VGU Vario Gearbox Unit mostly finds its employment in Continuous Shake Outs SOC, separating castings and moulding sand out of the moulding box. Especially for contract foundries this a big advantage. Sometimes more than 1,000 different parts are listed in the portfolio. Some castings are massive with many undercuts, others are fragile with thin walls. The program of the VGU offers numerous pre-dial set ups, which can be paired up to the different parts. This way every single casting gets its needed treatment.
The Vario Gearbox Unit changes the throwing angle in less than a second. Furthermore the revolution of the unbalanced drives can be changed to the customer’s needs.
