Above-mentioned purpose of the present invention is to realize by such technical scheme: a kind of high strength, resistance to abrasion conveyor chain, comprise two inner plates, described inner plate two ends are provided with flat hole, between described two inner plates, sleeve is installed, the flat hole interference fit of sleeve and inner plate, on described sleeve, be provided with and the roller of sleeve free-running fit, inner plate is installed and is coordinated with the first pin link plate, the second pin link plate by bearing pin.
Described the first pin link plate two ends are circular hole, the step end interference fit of the circular hole of the first pin link plate and bearing pin,
Described the second Wei Bian hole, pin link plate two ends, the flat square end interference fit of the flat hole of the second pin link plate and bearing pin,
The flat square end of bearing pin is provided with pin.
Between described sleeve and roller, be provided with the gap of 0.3mm ~ 0.4mm.
The circular hole at described bearing pin and the first pin link plate two ends is according to 0.10mm ~ 0.20mm interference fit.
The flat hole at the flat square end of described bearing pin and the second pin link plate two ends is according to 0.10mm ~ 0.20mm interference fit.
Described pin is T-shaped pin.
Described and the first pin link plate, the second pin link plate are Cheloniform plate or bent plate.
The beneficial effect of a kind of high strength of the present invention, resistance to abrasion conveyor chain is as follows: described inner plate and sleeve interference fit, prevent from causing because of gap in operational process elongating and wearing and tearing.The reserved 0.3mm-0.4mm of sleeve and roller gap, prevents from turning round card and rotating inflexible defect because of what work under bad environment caused.Described bearing pin coordinates the interference fit according to 0.10-0.20mm with the two ends circular hole of the first pin link plate, and the flat square end of described bearing pin coordinates the interference fit according to 0.10-0.2mm with the flat hole, two ends of the second pin link plate, prevents from causing elongating and wearing and tearing because of rotation.The flat square end of described bearing pin has been provided with T-shaped pin hole, and T-shaped pin is difficult for rotation can be prevented from coming off in long-term running.

The specific embodiment
As shown in Fig. 1 ~ Fig. 3, a kind of high strength, resistance to abrasion conveyor chain, comprising:
Two two ends offer the inner plate 3 in flat hole,
Be arranged between two inner plates 3 and with the sleeve 4 of the flat hole interference fit of inner plate 3,
Be arranged on sleeve 4 and with the roller 5 of sleeve 4 free-running fits.
The outside of inner plate 3 is provided with: the first pin link plate 1 and the second pin link plate 2.The first pin link plate 1 two ends are circular hole, with the step end interference fit of bearing pin 6.
The second pin link plate 2 Wei Bian holes, two ends, with the flat square end interference fit of bearing pin 6.The flat square end of bearing pin 6 is provided with the T-shaped pin of rotation-prevention.
Described two inner plates 3 and sleeve 4 interference fit, sleeve 4 and roller 5 reserved 0.3mm-0.4mm gaps, the circular hole at described bearing pin 6 and the first pin link plate 1 two ends is according to 0.10-0.20mm interference fit, the flat hole at the flat square end of described bearing pin 6 and the second pin link plate 2 two ends is according to 0.10-0.2mm interference fit, the flat square end of described bearing pin 6 offers T-shaped pin hole, and T-shaped pin is difficult for rotation can be prevented from coming off in long-term running.
The first pin link plate 1, the second pin link plate 2 can be made into by respective standard and requirement the forms such as Cheloniform plate, bent plate.In addition, on carrier bar, there is the assembly opening corresponding with hopper.Flat nose end can be dull and stereotyped and bent plate form, when this carrier bar is bent plate, generally has the assembly opening corresponding with hopper.
The manufacture method of conveyor chain of the present invention:
1), comprise that fracture of inside and outside carrier bar, one-shot forming, one-off hole-piercing guarantee that link center is apart from stable, carrier bar adopts 40Cr band steel to make, carry out modifier treatment through controllable continuous operation stove, its hardness number, at HRC26-32, guarantees its tension and yield strength performance the best.
2), bearing pin 6 quenches through surface high frequency after adopting 40Cr round steel processing, temper, had both possessed good quenching degree, guaranteed again the resistance to abrasion that it is best.
