Title:
DRIVER FOR A TWIN CUTTING DEVICE WITH COUNTER ROTATING BLADES
Document Type and Number:
WIPO Patent Application WO2006041407
Kind Code:
A8
Abstract:
The invention relates to a driver (1) for a twin cutting device (2), which comprises a first blade (4), which is non-rotatably arranged on a drive shaft (11) to be rotated about an axis of rotation (r_) in a first direction, and a second blade (3), which is non-rotatably arranged on a drive socket (15), which encloses the drive shaft (11), to be rotated about the same axis of rotation (r_) in a second direction opposite to said first direction. The drive shaft (11) constitutes a driving central shaft in a gear (10), which comprises a sun wheel (24), which is non-rotatably arranged on the drive shaft (11) to be rotated by the same, at least a first planet wheel (25), which meshes with the sun wheel (24) and is rotatable about an axis (p) parallel to the axis of rotation (r_), at least a second planet wheel (29), which is arranged to rotate simultaneously with the first planet wheel (25), and a gear rim (30), which with internal teeth meshes with the second planet wheel (29) and is non-rotatably mounted on the drive socket (15) to rotate the same.
