HAND-HELD IMPLEMENT

摘要

The invention relates to a hand-held implement having a drive motor (14) which drives a tool (4) in rotation by means of a belt drive (70). The belt drive (70) has at least one first, driving belt pulley (27) and at least one second, driven belt pulley (28). A second belt pulley (28) is non-rotatably connected to the tool (4). The rotational speed of the second belt pulley (28) in operation is less than the rotational speed of the first belt pulley (27). The implement has a braking device (25) which acts on the belt drive (70). At least one first drive belt (31) of a first drive stage and a second drive belt (32) of a second drive stage act between the first belt pulley (27) and the second belt pulley (28) for transmission of the driving torque. The first drive belt (31) and the second drive belt (32) each effect a reduction in the rotational speed. The belt drive (70) comprises at least one deflecting roller (35, 36) which bears against at least one drive belt (32). In this way braking of the tool (4) is made possible regardless of the rotational speed of the tool.
