Abstract:
A separating- and support element (20, 21) for milling drums (1) on milling machines for coarse, uneven surfaces of concrete or asphalt or for the removal of street markings, comprising milling drums (1) having a tool holder (2), between the flanges (5) of which shafts (4) are positioned on a radius (x), onto which shafts the milling tools (3) which are mounted in a loosely rotatable manner are slid, whereby the number of milling tools (3) used can be freely determined in accordance with the use and the size of the milling tools (3), the milling tools (3) and separating- and support elements (20, 21) are mounted in the axial direction at any chosen point on the shafts (4) and between the flanges (5), alternating in a sequence that can be freely determined, whereby the separating- and support elements (20, 21) have a semi-circular recess (11, 12) comprising a maximum of 180Â°, with the diameter of the central tube (6) determining the outermost contours of the profile, whereby the distance between the center (a) of the central tube (6) and the center (aâ€²) of the boring (9) corresponds to the radius (x), and whereby the borings (9) serve for the accommodation of the shafts (4), the separating- and support element (20) encircles the central tube (6) with an opening (11) on one side by a maximum of 180Â°, and a double separating- and support element (21) is slid onto two shafts (4, 4â€²) and has on the side, at an angle of 90Â° from the connecting line between the centers of the shafts (4 and 4â€²), a recess (11) which proceeds around the central tube (6) on the side with a maximum of 180Â°.
