Description
Technical field
The utility model relates to a kind of chain.
Background technique
As a kind of important kind of drive, chain is used in many occasions.Usually, chain comprises internal sheet, and the through hole that described internal sheet two ends are provided with by its two ends is fixed with tubule and relatively between two to connect, and the outer rotating cover of tubule has bassoon, and two outer plates connect the head and the tail of two internal sheet respectively by round pin, forms the closed loop of chain transmission.When the chain of this structure is used for transmission, bassoon forms friction pair one with the mutual friction of upper saw pulley phase, and tubule forms friction pair two with the mutual friction of bassoon phase, and friction pair two is a line in theory, and area of contact is minimum, so just start quick abrasion; Although relatively inside and outside of chain wear amount is small-sized, when chain very long by much inside and outside form time, chain elongation amount can not be ignored, and affects transmission efficiency after chain elongation, even causes transmission failure; The tubule that during work, internal diameter is less bears shearing stress, and tensile strength is low, and increase along with wear extent increases friction pair area afterwards, the rate of wear diminishes.
Model utility content
The purpose of this utility model is to provide a kind of chain, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of chain, comprise some internal sheet and some outer plates, described internal sheet and outer plate end-to-end form the closed loop of a transmission; By being located at, through hole one near its two ends is relative with two bassoons to be fixedly connected with described any two pieces internal sheet, described outer plate is provided with semi-circle through hole two near two ends place, and semi-circle is positioned at side, outer plate two ends, described outer plate comprises the outer plate one and the outer plate two that are fixedly connected on this through hole two by slips pin, described slips pin sectional shape and through hole two adapt, and slips pin external diameter equals large bore, the rotating bassoon of passing two internal sheet from side respectively of two slips pins on described outer plate one, and opposite side and outer plate two fasten.
Further, described internal sheet and outer plate are being be straight line outside protrusion arc, intermediate portion along two ends on the section of transmission direction, and inner side is recessed arcuate structure.
Further, be inner side in described closed loop, described closed loop is outward outside.
The beneficial effects of the utility model are: rub proofness is high; Extend slow; Tensile strength is high.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.

In figure:
1, internal sheet; 11, through hole one; 2, outer plate; 21, outer plate one; 22, outer plate two; 23, through hole two; 3, bassoon; 4, slips pin.
Embodiment
As Figure 1-4, chain described in the present embodiment, comprise some internal sheet 1 and some outer plates 2, described internal sheet 1 and outer plate 2 end-to-end form the closed loop of a transmission, by being located at, through hole 1 near its two ends is relative with two bassoons 3 to be fixedly connected with described any two pieces internal sheet 1, described outer plate 2 is provided with semi-circle through hole 2 23 near two ends place, and semi-circle is positioned at side, outer plate 2 two ends, described outer plate 2 comprises the outer plate 1 and the outer plate 2 22 that are fixedly connected on this through hole 2 23 by slips pin 4, described slips pin 4 sectional shape and through hole 2 23 adapt, and slips pin 4 external diameter equals bassoon 3 internal diameter, the rotating bassoon 3 of passing two internal sheet 1 from side respectively of two slips pins 4 on described outer plate 1, and opposite side and outer plate 2 22 fasten.
Further, described internal sheet 1 and outer plate 2 are being protrusion arc along two ends on the section of transmission direction, and intermediate portion is the structure of outside for being recessed arc inside straight line.
Further, be inner side in described closed loop, described closed loop is outward outside.
During embody rule: when the chain of this structure is used for transmission, bassoon 3 on upper saw pulley and chain rubs and forms friction pair one, slips pin 4 rotates around bassoon 3 and forms friction pair two, because slips pin 4 external diameter equals bassoon 3 internal diameter, therefore friction pair two is the semi-cylindrical of slips pin 4, under same operating mode, same manufactured materials and process condition, face type friction pair is more secondary than linear friction has larger antiwear property, friction pair wear extent significantly reduces, and ensures that chain elongation speed is low; What bear shearing stress during transmission is have larger-diameter bassoon 3, and lifting surface area is large, ensure that higher tensile strength.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection domain of the present utility model.
