Abstract
The utility model provides a kind of protecting sleeve wear-resisting chain, and described chain comprises: multiple inner links 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 pin link plate and bearing pin; Described sleeve is arranged in the middle part of roller, and inner plate and pin link plate are arranged at respectively the two ends of roller from inside to outside; Described bearing pin intercalation is in sleeve, and two-end part is on pin link plate, and the two ends of described each pin link plate are respectively equipped with the protecting sleeve of a semicircle annular.This protecting sleeve wear-resisting chain arranges by the two ends of the pin link plate at chain the protecting sleeve that high-abrasive material is made, and ensures that particle directly contacts with protecting sleeve, strengthens the wear ability of carrier bar and particle contact surface, increases the service life of chain.
Description
Technical field
The utility model relates to a kind of chain, particularly a kind of protecting sleeve wear-resisting chain.
Background technology
Wear-resisting chain is the extraordinary chain of the one on a kind of load transfer device, 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 links and outer link, described inner link and outer link are connected in series with the form of hinges, wherein, inner link comprises inner plate 2 ', sleeve 5 ' and roller 4 '; Outer link comprises pin link plate 1 ' and bearing pin 3 '; Described sleeve 5 ' is arranged in the middle part of roller 4 ', and inner plate 2 ' and pin link plate 1 ' are arranged at respectively the two ends of roller 4 ' from inside to outside; Described bearing pin 3 ' intercalation is in sleeve 5 ', and two-end part is on pin link plate 1 ', in the situation that normal granules is worn and torn, chain and particle contact surface, the lateral surface wearing and tearing that are pin link 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.
Utility model content
The utility model, for above shortcoming, provides a kind of protecting sleeve wear-resisting chain to solve the problem of pin link plate serious wear.
For achieving the above object, the utility model takes following technical proposals to realize:
A kind of protecting sleeve wear-resisting chain, described chain comprises: multiple inner links 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, sleeve and roller; Outer link comprises pin link plate and bearing pin; Described sleeve is arranged in the middle part of roller, and inner plate and pin link plate are arranged at respectively the two ends of roller from inside to outside; Described bearing pin intercalation is in sleeve, and two-end part is on pin link plate, and the two ends of described each pin link plate are respectively equipped with the protecting sleeve of a semicircle annular.
Further, described protecting sleeve is arranged on the lateral surface of pin link plate.
Further, described bearing pin is through protecting sleeve.
Further, the thickness of described protecting sleeve is greater than the thickness of pin link plate.
Protecting sleeve wear-resisting chain of the present utility model arranges by the two ends of the pin link plate at chain the protecting sleeve that high-abrasive material is made; ensure that particle directly contacts with protecting sleeve; strengthen the wear ability of carrier bar and particle contact surface; increase the service life of chain; overcome the technology prejudice of prior art; fill up the technology blind area of prior art, obtained beyond thought effect by improvement.
Further, protecting sleeve is only arranged on the lateral surface of pin link plate, on particle direct contact surface, cost-saving.
Further, adopt bearing pin fixing firmly reliable, simultaneously cost-saving.
Further, the thickness of protecting sleeve is greater than the thickness of pin link plate, and wear resisting property is better, makes chain overall wear degree consistent.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 3 is the front elevation of wear-resisting chain in better embodiment of the utility model, and Fig. 4 is the birds-eye view of wear-resisting chain in Fig. 3.Comprise in conjunction with the wear-resisting chain in Fig. 3 and the known the present embodiment of Fig. 4 the multiple inner links and the outer link that are connected in series with the form of hinges.Wherein, inner link comprises inner plate 2, sleeve 5 and the roller 4 of pair of parallel; Outer link comprises the pin link plate 1 of pair of parallel, bearing pin 3.
The two ends of described inner plate 2 are respectively equipped with pin-and-hole, and the two ends of pin link plate 1 are also provided with the pin-and-hole of answering in contrast.
Between the inner plate 2 of pair of parallel, be respectively equipped with roller 4 at two ends place, between roller 4 and inner plate 2, leave a fixed gap.
Sleeve 5 is arranged in the middle part of roller 4, passes the pin-and-hole of inner plate 2 simultaneously.
Fig. 5 is the single outer link schematic diagram of protecting sleeve wear-resisting chain in Fig. 3, and as shown in Figure 5, the two ends of pin link plate 1 are respectively equipped with the protecting sleeve 6 of a semicircle annular.The thickness of protecting sleeve 6 is greater than the thickness of pin link plate 1.Protecting sleeve 6 is wrapped in the outside of pin link plate 1.
Protecting sleeve 6 is arranged on the lateral surface of pin link plate 1, and bearing pin 3, through protecting sleeve 6, is fixed on pin link plate 1.
Bearing pin 3 is respectively through protecting sleeve 6, and the pin-and-hole of pin link plate 1, then through sleeve 5 inside; again pass the pin-and-hole of another pin link plate 1 paralleling; then through another protecting sleeve 6, inner plate 2, pin link plate 1 and protecting sleeve 6 are firmly connected, have ensured the rotation of adjacent link freely simultaneously.
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.
