Chain saw cutter links

摘要

Embodiments of chain saw cutter links, and related apparatuses and methods. For example, in some embodiments, a cutter link may include a top plate, a sharpened surface having an upper end and a lower end, and a depth gauge having a top surface. The sharpened surface may define a reference line tangent to the sharpened surface at the upper end such that the reference line extends between the top plate and the sharpened surface, a sharpened width may be defined by a minimum distance between the reference line and the lower end of the sharpened surface, an opening width may be defined by a minimum distance between the reference line and the top surface of the depth gauge, and the sharpened width may be greater than the opening width.

主权项

1. A cutter link, comprising:
a top plate; a depth gauge having a top surface; and a sharpened surface having an upper end, a lower end, a sharpening axis, wherein the sharpened surface between the upper end and the lower end is substantially circular as viewed along the sharpening axis, and wherein the sharpened surface curves upward at the bottom toward the depth gauge; wherein: the sharpened surface defines a reference line tangent to the sharpened surface at the upper end such that the reference line extends between the top plate and the sharpened surface, a sharpened width is defined by a minimum distance between the reference line and the lower end of the sharpened surface, an opening width is defined by a minimum distance between the reference line and the top surface of the depth gauge, the sharpened width is greater than the opening width, the top surface of the depth gauge is below the upper end of the sharpened surface, a chip drag coefficient defined as equal to a ratio of the opening width to the arc length, wherein the chip drag coefficient is less than or equal to approximately 0.55.
