Invention illustrated and explained in the following description. It shows a schematic longitudinal section by a drive device.

The invention relates to a drive device for a foot attached to the machine frame

Rotary tube of a false twist machine with a plate 41 is a floor 47 ft, a cylinder wall

In the known drive devices of this pot are held. In the housing bottom 47 ft and in the form of a pot-like drive means housing cover 47 c are bearings 43 a and 43 ft for (French patent specification 1 217 494, Fig. 3, 6 45 intended to support a rotating spindle 42, and 7) therefore selected Because the drive pots intended for the drive of this spindle are the most likely to constructively achieve the desired goal of a belt 45 wrapped around the top, high constant speed of the driven rotating end of the spindle 42 and from the cover 47c leaves.

The invention is based on the knowledge that since in this case there is no passage opening for changes in the dimensions of the drive pot 60, an organ is present which prevents the horseshoes made of known thermoplastic materials in the magnets 49 from rotating with respect to the housing at extremely high speeds. 47, 476, 47c holds, novel precautions for force effects are justified sifid. The magnets were held off.
The magnet system consists of a horseshoe magnet pot and a bulging of the pot wall 65 49 including a bearing sleeve 46, which is determined with the help of when the speed of the pot is particularly high for bearings 46 and 46 ft . An eccentric displacement of the pot-rotating spindle 42 is also possible. The magnet system 49, rnndcs to the center of the pot can at particularly high 46 is opposite this rotating spindle 42 in
