Abstract
A tube motor with an electric motor drive with a drive shaft located in a gear box. A reducing gear with a driven shaft is located in a gear box and coupled with the drive shaft via a gear input shaft for rotary securing of the driven shaft especially when the drive is disengaged. A wrap spring brake with a wrap spring works against the gear box, while the drive shaft and the gear input shaft work together with the wrap spring. Located between the wrap spring and the gear housing and secured against torsion is an annular element which diverts a moment introduced by the driven shaft into the gear housing.
