Abstract
The utility model relates to a narrow-saw-line saw chain of a chain saw, and aims to solve the technical problem of providing the narrow-saw-line saw chain which is small in saw line width, small in saw cutting resistance, high in saw cutting efficiency, light in weight, and labor-saving in operation. The narrow-saw-line saw chain consists of a left cutting tooth chain sheet, a right cutting tooth chain sheet, a connecting sheet, an ordinary transmission chain sheet and an anti-rebounding transmission chain sheet riveted together by using chain axles, wherein the width of the saw line is 6.7 to 6.8mm. The thickness of a side chain sheet of the narrow-saw-line saw chain is 1.0 to 1.2mm, the briar dressing quantity of the left cutting tooth chain sheet and the right cutting tooth chain sheet is 2.5 to 2.7mm, the thickness of the transmission chain sheet is 1.26 to 1.29mm, and the height of rivet heads of the narrow-saw-line saw chain is 0.55 to 0.65mm. The hole distances of various chain sheets of the narrow-saw-line saw chain are not equal and comprise short hole distances and long hole distances, and the pitch of the saw chain is 8.25 to 9.52mm.
Description
Technical field
The utility model relates to chain saw, relates in particular to a kind of narrow swage set saw chain of chain saw.
Technical background
The thickness of the various chain sheets of the saw chain that uses at present is larger, and the material toggling amount of Cutting teeth chair blade is also larger, thereby saw kerf width is large, and the sawing resistance is also large, is contained on chain saw or the electric chain saw, and cutting-rate is lower, and the operation effort.Because the thickness of existing saw chain chain sheet is larger, stamping and blanking and stamping resistance are larger, need more large-scale pressing equipment, and drawing velocity is also lower, and required steel are more when making, thereby manufacturing cost is higher, and the weight of saw chain own is also larger.Chain saw and electric chain saw are a kind of hand-hold type power machinery, and original machine power is limited, for improving cutting-rate and alleviating operator's labour intensity, should reduce saw kerf width and the weight and the steering force that alleviate chain saw as far as possible.
Summary of the invention
The purpose of this utility model provides a kind of narrow swage set saw chain, and its saw kerf width is little, and the sawing resistance is little, and cutting-rate is high, and lightweight, rapid operation.
The purpose of this utility model is achieved in that described narrow swage set saw chain is formed with the chain rivet riveted joint by left Cutting teeth chair blade, right Cutting teeth chair blade, brace, common drive link, anti-bounce-back drive link, saw kerf width is 6.7-6.8mm, much smaller than the saw kerf width 7.6-8.6mm of general saw chain.The side chain sheet thickness of described narrow swage set saw chain is 1.0-1.2mm, much smaller than the side chain sheet thickness 1.3-1.5mm of general saw chain.The Cutting teeth chair blade material toggling amount of described narrow swage set saw chain is 2.5-2.7mm, less than the Cutting teeth chair blade material toggling amount 3.0-3.4mm of general saw chain.The drive link guide part thickness of described narrow swage set saw chain is 1.26-1.29mm, much smaller than the drive link guide part thickness 1.5-1.6mm of general saw chain.The drive link connecting portion thickness of described narrow swage set saw chain is 1.26-1.49mm, less than the drive link connecting portion thickness 1.5-1.6mm of general saw chain.The manufactured head height of described narrow swage set saw chain is 0.6-0.65mm, less than the manufactured head height 0.7-0.75mm of general saw chain.The pitch-row of the various chain sheets of described narrow swage set saw chain is unequal, short pitch-row and slotted hole is arranged apart from two kinds, and the mean value of short pitch-row and slotted hole distance is the pitch of saw chain, and the pitch of described narrow swage set saw chain is 8.25-9.52mm.
Because the side chain sheet thickness of described narrow swage set saw chain is much smaller than the side chain sheet thickness of general saw chain, the Cutting teeth chair blade material toggling amount of described narrow swage set saw chain is less than the Cutting teeth chair blade material toggling amount of general saw chain, the saw kerf width of described narrow swage set saw chain is the saw kerf width much smaller than general saw chain, the drive link guide part thickness of described narrow swage set saw chain and drive link connecting portion thickness are much smaller than drive link guide part thickness and the drive link connecting portion thickness of general saw chain, so the sawing resistance of described narrow swage set saw chain is little, cutting-rate is high, and lightweight, rapid operation.
