Description

Technical Field

[0001] This utility model belongs to the field of saw chain technology, specifically relating to a high-efficiency saw chain. Background Technology

[0002] A chainsaw is a hand-held saw powered by a lithium battery or gasoline engine, primarily used for logging and timber processing. Its working principle relies on the lateral movement of staggered 7-shaped cutting teeth on the saw chain to perform the cutting work. The cutting teeth are arranged alternately on the chain, and the distance between the outer tangents of the staggered cutting teeth determines the maximum cutting width. However, existing chainsaws are not efficient enough, are heavy, and inconvenient to carry, failing to fully meet the lightweight requirements of new application scenarios. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a high-efficiency saw chain to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A high-efficiency saw chain is composed of a left-cutting tooth chain piece, a right-cutting tooth chain piece, a connecting piece, and a transmission piece with transmission function, which are riveted together by a chain shaft;

[0006] The kerf width A is determined by the upper cutting edges of the left and right cutting chain plates, and the kerf width A = 4.85-5.65 mm;

[0007] A maximum height C is determined from the bottom of the transmission plate with transmission function to the highest part of the left and right cutting tooth chain plates, and the maximum height C = C1 + C2 = 12.75-13.45 mm;

[0008] An average pitch T is determined by the hole spacing T1 of the transmission plate with transmission function and the hole spacing T2 between the connecting plate and the left and right cutting tooth chain plates, and T = (T1 + T2) / 2 = 7.35 mm, S = A * C * T = 451 - 550 mm3.

[0009] Furthermore, the thickness of the left and right cutting tooth chain plates is 0.9 mm.

[0010] Furthermore, the thickness of the transmission plate with transmission function is 1.1 mm.

[0011] Furthermore, the rivet head height of the chain shaft is 0.4-0.6mm.

[0012] Furthermore, T2 > T1.

[0013] Furthermore, C1 > C2.

[0014] Furthermore, T2 / T1 is 1.15-1.2mm.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The saw chain of this invention is lightweight, easy to operate, and convenient to carry; the saw chain size is reduced and the tooth pitch is shortened, making it less prone to shaking during use and producing a smoother cut surface, resulting in greater stability and safety, as well as lower energy consumption; at the same time, the left / right cutting teeth's punching and bending angles are optimized, and the cutting amount and discharge space are adjusted, greatly improving its cutting efficiency.
