Wood chipping machine cutter ring blade clamp - has two armed lever with longer arm under spring pressure

摘要

The wood chipping machine has a cutter ring rotating in a casing, with two axially spaced rims, interconnected by axially and radially extending ring stems with chipping blades fixed to their inside edges and form-locked by a clamp. The clamping unit comprises a two-armed lever (6) with swivel axis parallel to the cutter ring's (2) rotational axis. The shorter arm (6a) activates the chipping blade (5), and the longer arm (6b) is activated by springs (7), set axially close together, pressing the lever into its clamping position, and supported on the ring stem (4). There may be several narrow levers for each blade.
