摘要： Chain bar apparatus and methods are disclosed that may be formed from plastic, metal or other materials. Laser cutting of a chain bar core can provide improved structural characteristics, for example when adhesive is used to assemble the chain bar. Flow diversion elements can be used to optimize flow throughout the chain bar.

摘要： A method of modifying a cutter link (240) of cutting chain (200) for a chainsaw (100) may include forming the cutter link (240) to include a base portion (280) and a cutting portion (270) extending away from the base portion (280). The cutting portion (270) may include a side plate (300/500) and a top plate (310/510). The top plate (310/510) may include a top plate leading edge (312/412/512) and a bottom face (314/414/514). The side plate (300/500) may include a side plate leading edge (302/402/502) and an inside face (304/404/504). The method may further include removing at least a portion of material forming the bottom face (314/414/514). The portion of material forming the bottom face (314/414/514) that is removed decreases as distance from the top plate leading edge (312/412/512) increases.

摘要： According to the invention, in the arm of a chain saw machine, guide pieces or modules of the lateral guide (104) are provided for the cutting chain (103) and determine, when assembled on the sawing machine arm, an assembly with a contact overlap zone at their ends and between each pair of said contiguous lateral guide pieces, and such overlap zone prevents a lubricating means from exiting between the flanked ends of the pieces. The thickness of the lateral guide (104) is not increased due to these overlaps and remains substantially constant.

摘要： A lightweight guide bar (16) formed from a heavy material, e.g., steel, and having a center section, e.g., a cavity of reduced material (30) and fitted with a lighter weight insert, e.g., aluminum plate (36). The center section includes a flange to which the aluminum plate is adhered and a spacer lip (34) defines the desired thickness of the adhesive. Adhesive is applied to the desired thickness under the lip and the aluminum plate is abutted against the lip and into contact with the adhesive for adhering of the plate to the flange. In a preferred embodiment, the flange is a continuous web (32) down the center of the center section and insert plates are adhered to each side of the web. Also, preferably the inserts are oval and symmetrical and are selectively mechanically secured to the flanges by rivets (44).

摘要： A chainsaw comprises a main body (1), a motor housed within the main body, the motor being drivably connected to a sprocket drive shaft (6), and a guide bar/saw chain assembly (4). The assembly (4) comprises a guide bar (7, 8), a saw chain (12) and a sprocket drive wheel (5). The guide bar has first and second guide bar portions (7, 8) telescopically connected together, and the sprocket drive wheel (5) is associated with the second guide bar portion (8). The saw chain (12) is in drivable engagement with the sprocket drive wheel (5) and passes around the peripheries of the first and second guide bar portions (7, 8). The sprocket drive wheel (5) is in drivable engagement with the sprocket drive shaft (6). The assembly (4) is movable between a first, non-operative position in which the first and second guide bar portions (7, 8) are positioned so that the saw chain (12) is not tensioned, and a second, operative position in which the first and second guide bar portions are positioned so as to tension the saw chain.
