摘要： A power-tool cutting device includes at least one cutting strand, at least one guide unit configured to guide the cutting strand, and at least one deflecting unit. The guide unit together with the cutting strand forms a closed system. The deflecting unit is arranged on a drive-remote side of the guide unit and has at least one movably mounted deflecting element configured to deflect the cutting strand at least while the cutting strand revolves about the guide unit. The deflecting element includes at least one contact surface for an at least temporary contact with the cutting strand. The deflecting element is configured to be at least substantially free from an extension for engagement in the cutting strand.

摘要： Embodiments herein provide a modified pitch sprocket to provide an orientation of a saw chain link, such as a cutter link or drive link, with respect to the direction of travel of the link, as it traverses the sprocket that is different than the orientation of the link as it traverses a straight portion of the guide bar. In some embodiments, the modified pitch sprocket may orient the cutter link to provide radial extension for a depth gauge of the cutter link relative to a cutting element of the cutter link. This may facilitate shaping of the depth gauge and/or cutting element, such as by a sharpening element, as the cutter link traverses the sprocket.

摘要： A guide bar (1) is provided for a portable handheld work apparatus, such as a motor-driven chain saw or overhead branch cutter, and includes an elongated, flat base body (4) having a peripherally extending guide groove for guiding a saw chain (6). In the region of the direction-changing section (14) at the free tip (13) of the guide bar (1), the saw chain (6) is laterally partially covered by guide discs (17, 18) which rotate with the idler sprocket (19). The guide discs (17, 18) include radially projecting sections (20, 20′). Corresponding radially projecting sections (20) of one guide disc (17) are arranged offset relative to the radially projecting sections (20′) of the other guide disc (18). With this constructive measure, the manipulation of the portable handheld work apparatus is improved.

摘要： The invention is directed to a guide bar for a motor-driven chain saw (1) and includes a longitudinally extending flat base body (2) having a peripherally extending guide groove (3) for guiding a saw chain (4). In the region of the direction-changing section (12) of the guide bar (13), the saw chain (4) is partially laterally covered by guide discs (14, 14′), which rotate along with the idler sprocket (16). The guide discs (14, 14′) include radially projecting sections (18) whose number is identical with the number of the teeth (17) of the idler sprocket (16). The tendency to kickback of the motor-driven chain saw is reduced with these constructive measures.

摘要： A sprocket nose guide bar for guiding an endless saw chain. A configured sprocket is rotatably mounted in the nose of the bar and functions to elevate and transport the saw chain around the nose end. The teeth of the sprocket engage the drive links of the chain to lift the chain off the nose edge as the chain traverses the nose. The tooth tips project above the side link bearing surfaces and into configured notches whereby the teeth effectively provide the lifting action without entering the saw chain chassis.
