Problems solved by technology
Among them, the roller chain is a widely used chain type, which is mainly composed of outer pieces, inner pieces, pin shafts, sleeves and rollers; but the roller chain with this basic structure is not suitable for large-tonnage pressure rollers The reason is that the large-tonnage pressure wheel bears a large transmission force, and the existing ordinary transmission chain cannot withstand such a large moment, and is often easily worn or insufficient in strength, resulting in fragility, which directly affects the transmission of the large-tonnage pressure wheel

Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 , 2 As shown, a chain for a large-tonnage press wheel according to the present invention is mainly composed of a plurality of chain links sequentially connected in series with pins 4, and the chain links are composed of a left chain link unit and a right chain link unit , wherein the left chain link unit has two step-shaped connecting pieces 7 that shrink outward and expand inwardly. A roller 5 is sandwiched between the outer shrinking pieces 71 of the stepped connecting piece 7 and a sleeve is sheathed in the center hole of the roller. 6. The two ends of the sleeve 6 are respectively fixed in the sleeve holes of the outer shrinking piece 71 of the stepped connecting piece 7;
[0012] One side end of an annex 2 is sandwiched between the two side expansion pieces 72 of the step-shaped connecting piece 7 and is connected with the connecting pin 4, and the other side...

A chain for a large-tonnage pinch roller is mainly formed by connecting a plurality of chain links through connecting pins sequentially in series. Each chain link is composed of a left chain link unit and a right chain link unit, wherein the left chain link unit is provided with two externally contracting and internally expanding step-shaped connecting pieces, a roller is clamped between contracting pieces on the outer sides of the step-shaped connecting pieces, a sleeve penetrates through a central hole of the roller, the two ends of the sleeve are fixed in sleeve holes of the contracting pieces on the outer sides of the step-shaped connecting pieces respectively, one side end of an accessory is clamped between expanding pieces on the two sides of the step-shaped connecting pieces and connected through the connecting pin, and the other side end of the accessory is connected in one ends of two external pieces of the corresponding right chain link unit in a penetrating mode through the connecting pin. The ends of every two chain links are connected in the mode that the two external pieces of one chain link are clamped on the outer sides of the two contracting pieces of the other adjacent chain link and penetrate through the central hole of the sleeve through the connecting pins, and then the two ends of the connecting pins penetrate through the adjacent contracting pieces and external pieces on the two sides.
Description
technical field [0001] The invention relates to a chain for large-tonnage pressure rollers, which belongs to the technical field of transmission chains. Background technique [0002] The chain is a multi-purpose mechanical transmission part composed of rigid components and a flexible system. It is mainly used to meet the functional requirements of transmission, transportation, and pulling. Among them, the roller chain is a widely used chain type, which is mainly composed of outer pieces, inner pieces, pin shafts, sleeves and rollers; but the roller chain with this basic structure is not suitable for large-tonnage pressure rollers The reason is that the large-tonnage pressure wheel bears a large transmission force, and the existing ordinary transmission chain cannot bear such a large moment, and is often easily worn or insufficient in strength, resulting in fragility, which directly affects the transmission of the large-tonnage pressure wheel.
