The present disclosure relates to a method () for production of a chainsaw guide bar (). The method comprises the steps of providing () an elongated core plate () extending along a plane, and, in said plane has a length (Lc) in the longitudinal direction (D), and a width (Wc) perpendicular to the longitudinal direction (D), comprising a pair of opposite long side edges () and at least one detachable element () that extends along at least one of the long side edges of the core plate. Arranging () a side plate () on each side of the core plate (), thereby forming a sandwiched structure and joining () of the plates () for formation of an elongated guide bar (), wherein the at least one detachable element () remains attached to the core plate (). The disclosure also relates to a guide bar () for a chainsaw (). The guide bar () comprises a laminated structure of at least three layers comprising a first side plate (), a second side plate (), and a core plate () disposed between said first side plate () and said second side plate (), wherein the core plate () is provided with at least one detachable element (). The disclosure also relates to an alternative method () of production of a chainsaw guide bar ().

Methods for production of a guide bar for a chainsaw and a guide bar for a chainsaw

A chainsaw () includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar () around which a chain is rotatable. The guide bar () includes a first side plate () and a second side plate () facing each other and extending away from the housing () to a nose of the guide bar (), the first and second side plates (and) each including an inner sidewall (and) facing inwardly toward each other. Each of the inner sidewalls (and) includes a recessed portion () at which material of the inner sidewalls (and) has been removed.

Lightweight chainsaw guide bar

A chainsaw () includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar () around which a chain is rotatable. The guide bar () includes a laminated structure in which different ones of the layers of the laminated structure are comprised of different materials.

A chainsaw () includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar () around which a chain is rotatable. The guide bar () includes first and second side plates (and), a sprocket wheel (), first and second shims (and), and first and second sealing members (and). The first and second side plates (and) each face other and extend away from a housing () to a nose. The sprocket wheel () is provided at the nose between the first and second side plates (and). The first and second shims (and) are disposed between the first and second side plates (and), respectively, and corresponding ones of first and second sides of the sprocket wheel (). The first sealing member () is disposed between the first shim () and the first side of the sprocket wheel (). The second sealing member () is disposed between the second shim () and the second side of the sprocket wheel ().

Chainsaw guide bar roller bearing seal

The invention relates to a saw chain depth gauge filing template (), comprising a first flat section () and a second flat section (), wherein both sections () are made from a single piece of flat metal, especially from sheet metal, wherein the first flat section () has a first bearing surface () for a cutter link edge () of a saw chain () to be filed, wherein the second flat section () has second bearing surfaces () for a drive link () of the saw chain (), wherein the second surfaces () are established by an linear edge () in which at least two incisions () are machined, wherein the second flat section () has at least one cutout () for a part of the saw chain () to be sharpened by filing. Furthermore, the invention relates to a method for sharpening a saw chain by using such a saw chain depth gauge filing template. By the proposed concept filing of a saw chain becomes possible in a more precise way.
