摘要： A cutting assembly of a chainsaw includes a saw chain and a guide bar (4) for guiding the saw chain (3) along a peripheral edge (5) of the guide bar. The saw chain (3) has drive links (6) having drive bases (7) which with their side surfaces (8, 8′) are slidingly guided between the side walls (9) of a guide groove (10) of the guide bar (4) with the formation of a friction pairing. Lubricant pockets (11) are formed in the side surface (8). The lubricant pockets (11) are only open toward the corresponding side wall (9) of the guide groove (10) and are otherwise closed. Offside the lubricant pockets (11), the side surface (8) has a flat sliding surface (12) which slides on the side wall (9) of the guide groove (10). The lubricant pocket (11) has a mean diameter and a maximum depth. The ratio of the mean diameter to the maximum depth lies in a range of 5.0 up to and including 25.0.

摘要： A saw chain for the guide bar of a power chain saw includes pivotably interconnected drive links, cutting links or connecting links. The cutting link has a cutting tooth and a depth limiter that leads the cutting tooth. The drive link adjacent to the depth limiter is provided with a support protuberance and a support surface that during travel of the saw chain about the end of the guide bar cooperates in a supporting manner with the depth limiter. With the saw chain extended, the support protuberance has a smaller spacing to the cutting tooth than does the depth limiter. During travel of the saw chain about the end of the guide bar, the spacing of the support protuberance to the cutting tooth increases to a reversal spacing that is greater than the spacing of the depth limiter to the cutting tooth. In a side view of the saw chain, the spacing between the cutting tooth and the depth limiter is limited by the support protuberance. The support surface in both the extended state and during travel about the end of the guide bar lies beneath the top surface of the depth limiter.

摘要： A cutter head assembly for a motor chain saw has a cutter head housing and a drive shaft mounted in and projecting from the cutter head housing. A drive pinion is mounted on the portion of the drive shaft projecting from the cutter head housing. A guide bar having a first end positioned adjacent to the drive pinion is provided. A saw chain is driven by the drive pinion and circulates on the guide bar. A cover covering the drive pinion and resting at least in an area of outgoing deflection of the saw chain at a housing wall of the cutter head housing defines a cuttings chamber open toward the guide bar. The first end of the guide bar is clamped between the housing wall of the cutter head housing end the cover. The cover has a cuttings ejection opening opposite the housing wall in the vicinity of the area of outgoing deflection. The cuttings ejection opening has a rim extending in a circulating direction of the saw chain and a ramp projecting from a first portion of the rim into the cutting chamber.
