Slewing rings
Wire race bearing with integrated direct drive
Franke slewing rings with integrated direct drive (torque motor) are characterized by high dynamics, energy efficiency and a compact installation space with large central clearance.
Franke wire race bearings with integrated direct drive are characterized by maximum energy efficiency. The integration of the drive motor into the bearing makes it possible to dispense with components such as gears and drive pinions and therefore complex lubrication circuits. The moving masses are therefore significantly lower and the loss of power due to factors such as friction and play is minimized.
Torque motors are integrated directly into Franke slewing rings. The customer receives a completely ready-to-install system. This makes it possible not only to generate a rotational movement, but also to position or execute definable cycle steps.
The torque motor has a high torque at a defined speed range. The distance between the stator and rotor (air gap) is decisive for the magnitude of the torque. The pre-tensioned Franke slewing ring guarantees a constant air gap. A measuring system can be used to determine the motor position.
All measuring systems available on the market can be integrated into the slewing ring. Very robust inductive measuring systems are used as standard. They are available as incremental or absolute systems in various accuracy classes. The following interfaces are available: Incremental systems with TTL, 1 Vpp and absolute systems with EnDat 22 - Fanuc, BiSS, SSI, 1 Vpp.
The (closed) measuring tape is attached directly to the rotor and the measuring head is bolted to the stator. It is also conceivable to attach a measuring system to the customer's downstream construction. As the measuring tape is a closed ring, only certain diameters are available, which must be taken into account in the design. For larger quantities, any diameter is available, but this can result in additional costs.
