The RGT planetary roller screw consists of the following components: threaded planets, thread rolls, threaded nut, spacer rings and gear rings. The axial load is transmitted by the threaded spindle via the threaded planets into the threaded nut. The system is synchronized through gears on the planets and via two gear rings. The spacer rings, similar to the cage in a needle bearing, ensure the distance between the thread rolls on the circumference of the threaded spindle.
Spindle nominal Ø: 5 mm to 245 mm
Total spindle length: up to 10 m max.
Leads: 1 mm to 50 mm
Dynamic load ratings: up to Cdyn 5,800 kN
Static load ratings: up to Cstat 40,000 kN
Planetary roller screws are basically used wherever an electromechanical linear drive with high precision, accurate repeatability and high load capacity is required.
The field of application mainly includes:
- Axle drives in machine tools
- Servo press drives
- Robotics applications
- Lock and bridge drives
- Automation applications in metering and joining technology for the automotive industry
Various nut designs with different mounting options are available. If preloading of the planetary roller screws is desired, it can be achieved with so-called single-piece ground-to-fit or two-piece nut halves that are preloaded against each other. This is the reason for the subdivision of the nuts into so-called "preloaded" and "non-preloaded" in the nuts product key.
