Embodiment Construction

[0013] Some example embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some but not all example embodiments are shown. Indeed, the examples described and illustrated herein should not be construed as limiting the scope, applicability, or configuration of the disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term "or" shall be construed as a logical operator whose result is true if one or more of its operands is true. As used herein, operable coupling shall be understood to refer to direct or indirect connections which, in either case, enable functional interconnection of components that are operably connected to each other.

Abstract

A method of modifying a cutter link (240) of cutting chain for a chainsaw 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) and a top plate (310). The top plate (310) may include a top face (316) and a bottom face (314). The side plate (300) may include an outer face and an inside face (304). The method may further include determining a maximum non-homogeneous material hardness expected to be encountered during cutting operations, selecting a coating material having a hardness at least 1.3 times the maximum non-homogeneous material hardness, and coating a treated surface of the top plate (310) and / or the side plate (300).

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Provisional Application No. 62 / 128,125, filed March 4, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The exemplary embodiments relate generally to hand-held power equipment and, more particularly, to cutting chain improvements for chainsaws. Background technique [0004] Chainsaws are often used both commercially and privately to cut wood or perform other severe cutting operations. Because chainsaws are typically used in outdoor environments, and the work they are used to perform is oftentimes inherently debris-generating, chainsaws are generally relatively robust hand-held machines. They may be driven by a gasoline engine or an electric motor (eg, via a battery or a wired connection), turning the chain around a guide bar at relatively high speeds. The chain includes cutting teeth that engage wood or another medium to cut throu...
