    摘要: A typically battery-operated power tool, such as a chainsaw or hedge trimmer, comprising a working element (4), a motor (6) arranged to drive the working element (4) and a controller (9) arranged to control the speed at which the motor drives the working element (4), in which there is provided a sensor (12) for at least one factor indicative of the efficiency with which the power tool is being operated, the controller (9) being arranged to vary the speed at which the motor (6) drives the working element (4) should the factor indicate that the power tool is being operated in a sub-optimal manner. Typically, the factor is the pressure which the user is applying the power tool, and the sensor (12) is a sensor for the current flowing through the motor (6).

    摘要: To facilitate the demounting of a chain (3) from a chainsaw, the saw has a lever arm preferably in the form of hinged cover (11) arranged to displace the sprocket (15) towards the guide bar (2) the other upon opening of the cover (11). Upon closing the cover (11), the sprocket (15) is displaced in the opposite direction to pre-tension the chain (3). The sprocket (15, 115) may be driven over a gear transmission (27, 127), which when the chain (3, 103) is running at ordinary cutting speed uses resulting forces to automatically tension the chain (3, 103) by displacing the sprocket (15, 115) away from the guide bar (2, 102). A ratchet mechanism (34) may be provided to maintain the chain tension upon reduction of the chain speed by preventing the sprocket (15) from moving toward the guide bar (2).Alternatively, a mechanism for automatically tensioning the chain (3, 238) of a chainsaw includes a driving inner sprocket (76, 201), and an outer ring member (77, 204) surrounding the inner sprocket (76, 201). A spring (64, 87, 228) may be provided for assisting the ratchet mechanism or as a substitute therefore.

    摘要: A chainsaw includes a chainsaw body, a chainsaw bar configured to be operably coupled to a cutting chain, and a clutch cover disposed proximate to a portion of the chainsaw bar to facilitate clamping the chainsaw bar to the chainsaw body. The clutch cover may be configured to receive a tension sub assembly disposed at a portion of the clutch cover to enable both adjustment of chain tension in a first mode of operation and clamping of the chainsaw bar in a second mode of operation. The tension sub assembly may include a mode shift mechanism configured to move between a first position in which the tension sub assembly operates in the first mode and a second position in which the tension sub assembly operates in the second mode.

    摘要: A hand-held motor-driven cutting device is provided, comprising a motor 2, a first cutting tool 3, and a first transmission arranged to translate a rotating motion to a reciprocating motion of the first cutting tool 3. The first transmission comprises a first rotatable part 6 arranged to be driven by the motor 2 and a first connecting rod 9 with a first end 11 and a second end 12. The first end 11 is eccentrically connected to the first rotatable part 6 at a first connecting point 10 of the first rotatable part 6 and the second end 12 is connected to the first cutting tool 3. The first transmission 5 comprises a force limiting element 4 arranged between the first rotatable part 6 and the first cutting tool 3 in order to prevent a transmitted force applied to the first cutting tool 3 from exceeding a predetermined force level. The present invention also relates to a method of transmitting momentum in a hand-held motor-driven cutting device.
