Drive for a coffee brewing device and coffee brewing device

A brewing device comprising a drive, wherein the drive comprises:

• a first gearwheel defining an internal thread, via which said first gearwheel is pivot-mounted on an external thread of a guide cylinder, so that the first gearwheel is configured to move along a cylinder axis of the guide cylinder in response to a rotation;
• a second gearwheel configured to engage with said first gearwheel to drive the first gearwheel along the cylinder axis;
• a housing, in which the first gearwheel is accommodated;
• a brewing piston, which is coupled to the housing, so that said brewing piston is configured to move together with the first gearwheel along the cylinder axis;
• and
• a linear guide configured to guide the housing, which runs at a distance parallel to the cylinder axis and with which the housing is engaged such that a movement of the housing opposite to the linear guide in a radial direction to the cylinder axis is prevented,
• wherein the second gearwheel defines an axis of rotation arranged in a provided distance relative to the linear guide.
