Abstract
The utility model provides a kind of orientation and thickens wear-resisting chain, and described chain comprises: multiple inner link and outer link, and described inner link and outer link are connected in series with the form of hinges, and wherein, inner link comprises inner plate, sleeve and roller; Outer link comprises outer plate and bearing pin; Described sleeve is arranged in the middle part of roller, and inner plate and outer plate are arranged at the two ends of roller from inside to outside respectively; Described bearing pin intercalation is in sleeve, and two-end part is on outer plate, and the width of the side of described each outer plate is greater than the width of opposite side respectively.This wear-resisting chain by the most serious chain board of chain and particle contacts, increases the surface of contact thickness of outer plate and particle, the wear resistance in reinforcement carrier bar and particle contacts face, the working life of increase chain.
Description
Technical field
The utility model relates to a kind of chain, particularly a kind of wear-resisting chain.
Background technique
Wear-resisting chain is the extraordinary delivering chain of one on a kind of conveying equipment, is widely used in article delivery or the transmissions such as harbour, mine, metallurgy, mining machinery.Existing wear-resisting chain as depicted in figs. 1 and 2, multiple inner link and outer link, described inner link and outer link are connected in series with the form of hinges, and wherein, inner link comprises inner plate 2 ', sleeve 5 ' and roller 4 '; Outer link comprises outer plate 1 ' and bearing pin 3 '; Described sleeve 5 ' is arranged in the middle part of roller 4 ', and inner plate 2 ' and outer plate 1 ' are arranged at the two ends of roller 4 ' from inside to outside respectively; The intercalation of described bearing pin 3 ' is in sleeve 5 ', and two-end part is on outer plate 1 ', when normal granules is worn and torn, chain and particle contacts face, namely the outer side surface wearing and tearing of outer plate 1 ' are local much more serious than other, have a strong impact on the life-span on probation of whole chain, and existing technical staff are absorbed in technology blind area, constantly select more wear-resisting integral material, or change whole chain.
Model utility content
The utility model, for above shortcoming, provides a kind of wear-resisting chain to solve the problem of outer plate serious wear.
For achieving the above object, the utility model is taked following technical proposals to realize:
A kind of wear-resisting chain, described chain comprises: multiple inner link and outer link, and described inner link and outer link are connected in series with the form of hinges, and wherein, inner link comprises inner plate, sleeve and roller; Outer link comprises outer plate and bearing pin; Described sleeve is arranged in the middle part of roller, and inner plate and outer plate are arranged at the two ends of roller from inside to outside respectively; Described bearing pin intercalation is in sleeve, and two-end part is on outer plate, and the width of the side of described each outer plate is greater than the width of opposite side respectively.
Further, the width at two ends, described outer plate side is greater than middle width.
Further, in the every one end of described outer plate, the curvature of the side that is connected with inner plate is greater than the curvature of opposite side.
Wear-resisting chain of the present utility model is by chain and the most serious chain board of particle contacts, increase the surface of contact thickness of outer plate and particle, strengthen the wear resistance in carrier bar and particle contacts face, increase the working life of chain, overcome the technology prejudice of prior art, fill up the technology blind area of prior art, obtain beyond thought effect by improvement.
Further, the two ends of the side directly contacted due to outer plate and particle are worn and torn more serious, so its width is greater than middle width.
Further, according to the degree of wear that outer plate and particle directly contact, in the every one end of outer plate, the curvature of the side that is connected with inner plate is greater than the curvature of opposite side.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 3 is the front view of wear-resisting chain in the utility model better embodiment, and Fig. 4 is the plan view of wear-resisting chain in Fig. 3.Wear-resisting chain in composition graphs 3 and the known the present embodiment of Fig. 4 comprises the multiple inner link and outer link that are connected in series with the form of hinges.Wherein, inner link comprises pair of parallel inner plate 2, sleeve 5 and roller 4; Outer link comprises pair of parallel outer plate 1, bearing pin 3.
The two ends of described inner plate 2 are respectively equipped with pin-and-hole, and the two ends of outer plate 1 are also provided with the pin-and-hole corresponded.
Be respectively equipped with roller 4 at two ends place between pair of parallel inner plate 2, between roller 4 and inner plate 2, leave a fixed gap.
Sleeve 5 is arranged in the middle part of roller 4, simultaneously through the pin-and-hole of inner plate 2.
Bearing pin 3 is each passed through the pin-and-hole of outer plate 1, then inner through sleeve 5, again through the pin-and-hole of another outer plate 1 paralleled, inner plate 2, outer plate 1 is firmly connected, ensure that the rotatable of adjacent link simultaneously.
Fig. 5 is the schematic diagram of single outer link in Fig. 3.As shown in Figure 5, the width of side 11 that described each outer plate 1 and particle directly contact is greater than the width of opposite side respectively.
The width at the two ends, side 11 that described outer plate 1 and particle directly contact is greater than middle width, and in preferred described every one end, the curvature of the side 111 that is connected with inner plate is greater than the curvature of opposite side 112.
Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
