Title: COFFEE MILL AND AUTOMATIC COFFEE MACHINE HAVING A COFFEE MILL
Abstract:
The invention relates to a coffee mill, in particular for installation in automatic coffee machines, comprising an electric drive motor (1) for driving a grinder, wherein a reduction gearing (4) designed as a planetary gearing is arranged between the drive motor (1) and the grinder, the sun gear (3) of which reduction gearing can be driven by the drive motor (1). According to the invention, the planetary gearing has a plurality of planet bars (8) arranged around the sun gear (3) in the circumferential direction, which planet bars comprises a first axial section (7), which meshes with the sun gear (3), and an axially adjacent second axial section (9), which has a second diameter that is different from, preferably smaller than, a first diameter of the first axial section (7) and which meshes with a stationary ring gear (11), and the toothed bars are arranged so as to drive an output element (15) by means of the first axial sections (7) of the toothed bars.
