Planetary Gearbox Applications

2021-01-06

Press brakes are used for bending sheet metal. For this purpose, a bending punch presses the sheet metal into a die which determines the bending angle. Modern press brakes, which are often CNC-controlled, can be used to fold and bend steel sheets several centimetres thick. The multi-axis backgauge used in the planetary gear of the GSA070 series ensures the exact positioning of the plates. This can be controlled to move repeatedly between bends to produce complex parts.

 

n the in-mould labelling process (IML), pre-cut plastic films are inserted into an injection mould using a handling device. By applying a vacuum or static charge, the labels are fixed and then back-injected with plastic. The IML robots, which are equipped with a GSB065, handle the exact label loading of the moulds. IML robots are generally of modular design – the high positioning accuracy, fast availability and excellent price/performance ratio were crucial factors in the decision in favor of the GNP series.

 

The GNP090 planetary gear, with a gear ratio of i=10, is used as a machine axis drive (x- and y-axis) in laser cutting machines. A servo motor and a rack and pinion complete the unit. Thanks to the nominal input speed of 1,000 rpm and the maximum input speed of 3,000 rpm, the gearbox is ideally suited for use in fast, dynamic laser cutting machines. Due to the high positioning accuracy and high dynamic driveability, the GNP line is the ideal choice for applications of this sort.
