CUTTING HEAD FOR A MOTOR STRIMMER

机译:用于电机锋利的割头

摘要

The invention relates to a cutting head for mounting on a shaft end (2) of a brushcutter, comprising a split main body comprising an upper main body part (11) and a lower main body part (12) and at least one cutting tool (13) arranged between the main body parts (11, 12). , In the lower main body part (12) is rotatably a screw (37) for screw mounting of the lower body portion (12) held on the shaft end (2). During operation of the cutting head (10), the base body (90) is driven to rotate about a rotation axis (19). In the base body (90) has a bearing element (70) is fixed, which lies at a radial distance (m) to the axis of rotation (19). On the bearing element (70) a cutting tool (13, 73) is held. According to the invention, the upper basic body part (11) is non-rotatably connected to the shaft end (2) and the bearing element (70) fixed to only one main body part (12) and free at least in the circumferential direction of the main body (90) relative to the other main body part (11). such that the lower body portion (12) mounted on the shaft end (2) is rotatable relative to the upper body portion (11).
