摘要： The invention is directed to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The saw chain includes a plurality of side cutting links, a plurality of center driving links and a plurality of side connecting links. The links are pivotally interconnected by rivets to define the saw chain. Entrainers are formed on at least a portion of the connecting links and/or drive links to reliably hold a chip cut by a forward cutting tooth in the free space between two cutting links one directly behind the other. The chip is therefore prevented from slipping relative to the saw chain and is transported out of the kerf without affecting the cutting capacity of the next-rearward cutting link.

摘要： The invention is directed to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined direction. The saw chain includes: a plurality of cutting links, a plurality of driving links and a plurality of connecting links, the links being pivotally interconnected by rivets or the like to define the saw chain. The cutting links have respective cutting teeth disposed at a pregiven elevation above the guide bar. A plurality of non-cutting riders are mounted on selected ones of the links so as to be at an elevation corresponding approximately to the elevation of the cutting teeth for visibly marking the movement of the saw chain around the guide bar.

摘要： The invention is directed to a saw chain for a motor-driven saw such as a handheld, portable motor-driven chain saw. The motor-driven saw has a guide bar defining a track for accommodating and guiding the saw chain in a predetermined direction of movement. The saw chain includes a plurality of cutting links, a plurality of connecting links and a plurality of driving links, the links being pivotally interconnected by rivets or the like to define the saw chain. Each of the cutting links includes a plate-like body having a base web for defining rearward and forward openings for receiving respective ones of two of the rivets therein. The plate-like body has a rearward portion extending upwardly from the rearward region of the base web to define a cutting tooth. The plate-like body has a forward portion extending upwardly from the forward region of the base web so as to be spaced from the cutting tooth. The forward portion is bent over transversely to the direction of movement at a predetermined distance from the base web to define a depth limiter. The depth limiter has an upwardly directed top surface subdivided into a bearing face directly adjacent to the cutting tooth and an abutment face extending forwardly of the bearing face so as to be inclined downwardly in the direction of movement.

摘要： An arrangement for lubricating saw chains of power saws. The chains include chip removing members, cutting tooth members, connecting links, and other chain members joined by rivet connections. The extensions of the chip removing members run in a guide bar provided with an oil supply. The chip removing members are provided on at least one of their side surfaces with at least one oil guide in the form of a groove in the side surface, which guide extends counter to the running direction of the saw chain and at an incline upwardly toward the rivet connections. The oil guide merges into an oil channel which with at least one of its ends is located in the vicinity or close range of a rivet hole.

摘要： The invention is directed to a low vibration and low noise cutter arrangement for a motor-driven chain saw. The cutter arrangement includes a guide bar and a saw chain. The guide bar has a guide groove for the saw chain which extends along the peripheral edges of the guide bar. The saw chain includes center links and side connecting links which are pivotally connected to each other. The connecting links on the right-hand and left-hand sides of the saw chain include cutting links and side links which are displaced relative to each other. The center links are provided with respective rakers which engage in the guide groove and can be driven in the longitudinal direction of the guide bar by a drive sprocket. The connecting links are supported with slide surfaces on the peripherally extending guide surfaces which lie at both sides of the guide groove. An elastically resilient spacer element is arranged between the guide bar and the saw chain in order to provide a significant reduction of the occurring vibrations and of the noise emissions. When the saw chain is not under load, the slide surfaces of the connecting links are held at a spacing relative to the guide surfaces of the guide bar and, when the saw chain is under load, the resilient spacer element yields until the connecting links are in contact engagement with the guide surfaces.

摘要： A cutting assembly for a motor chainsaw has a guide bar with peripheral guide groove and guide surfaces. A saw chain circulates in the guide groove in a longitudinal direction of the guide bar. The saw chain has chain members such as centrally arranged drive members and connectors, laterally connecting the drive members. Some of the connectors and some of the drive members are embodied as cutters arranged alternatingly on opposite sides of the saw chain. Rivets connect the chain members pivotably to one another and extend transversely to the circulating direction. The drive members engage the guide groove and the connectors are slidably supported on the guide surfaces. Each cutter has a base, a support stay connected to the base, and a cutting tooth connected to the support stay. The cutting tooth has a laterally projecting roof portion having a leading end in the circulating direction with a roof cutting edge. The support stay has a first portion positioned in a central plane defined by the drive members, and the roof portion projects in a direction of the cutting plane of the saw chain in which direction the base also faces. The roof portion has an outer angled edge extending in the circulating direction parallel to the base. The angled edge has a lateral cutting edge positioned in front of the roof cutting edge in the circulating direction.
