    • The invention relates to a guide bar (9) for a saw chain (10) having a sword-shaped base body (16). A peripheral guide groove (11) is introduced into the periphery (17) of the base body (16). an oil-feed channel (22) is provided which opens into the guide groove (11) in the region of the groove bottom (23) and is fed from a transverse channel (21) lying below the groove bottom (23). The inlet opening (20) of the transverse channel (21) is at an outer side (9.1, 9.2) of the base body (16). The position, shape and size of the oil-feed channel (22) as well as the transverse channel (21) can be freely configured. This is achieved by arranging the transverse channel (21) in an insert part (25) separate from the base body (16). The insert part has the oil-feed channel (22). The insert part (25) is mounted in an open cutout (24) of the base body (16). The cutout (24) is open to an outer side (9.1, 9.2) of the base body (16) and extends substantially below the groove bottom (23).
    • 本发明涉及一种用于具有剑形基体(16)的锯链(10)的导杆(9)。 周边引导槽(11)被引入到基体(16)的周边(17)中。 设置有在槽底部(23)的区域内通向引导槽(11)的供油通道(22),并且从位于凹槽底部(23)下方的横向通道(21)进给。 横向通道(21)的入口(20)位于基体(16)的外侧(9.1,9.2)处。 可以自由地构造供油通道(22)以及横向通道(21)的位置,形状和尺寸。 这通过将横向通道(21)布置在与基体(16)分离的插入部分(25)中来实现。 插入部分具有供油通道(22)。 插入部分(25)安装在基体(16)的开口切口(24)中。 切口(24)向基体(16)的外侧(9.1,9.2)开口,并且基本上在槽底部(23)的下方延伸。
