Abstract
A high-strength wear-resistant conveyor chain comprises two inner chain plates. Flat holes are formed at two ends of each inner chain plate. A sleeve is mounted between the two inner chain plates and is in interference fit with the flat holes of the inner chain plates. A roller which is in clearance fit with the sleeve is arranged on the sleeve. The inner chain plates are mounted and matched with a first outer chain plate and a second outer chain plate through pin shafts. The high-strength wear-resistant conveyor chain is high in strength, wear-resistant, and especially suitable for bucket elevators and plate chain type scrapers.
Description
Technical field
A kind of high strength of the utility model, resistance to abrasion conveyor chain belong to chain and make the field.
Background technology

Above-mentioned purpose of the present utility model 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, roller with the sleeve free-running fit is installed on described sleeve, and inner plate is installed with the first pin link plate, the second pin link plate by bearing pin and is coordinated.
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 pin link plate two ends are flat hole, 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 equipped with pin.
Be provided with the gap of 0.3mm ~ 0.4mm between described sleeve and roller.
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 utility model, resistance to abrasion conveyor chain is as follows: described inner plate and sleeve interference fit prevent from causing because of the gap in operational process elongating and wearing and tearing.Sleeve and roller are reserved the 0.3mm-0.4mm gap, prevent from turning round card and rotating inflexible defective 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 flat hole, the 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 Fig. 1 ~ shown in Figure 3, a kind of high strength, resistance to abrasion conveyor chain comprise:
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 equipped 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 two ends are flat hole, with the flat square end interference fit of bearing pin 6.The flat square end of bearing pin 6 is equipped with the T-shaped pin of rotation-prevention.
Described two inner plates 3 and sleeve 4 interference fit, sleeve 4 is reserved the 0.3mm-0.4mm gap with roller 5, the circular hole at described bearing pin 6 and the first pin link plate 1 two ends is according to the 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 the 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, the assembly opening corresponding with hopper arranged on carrier bar.Flat nose end can be dull and stereotyped and bent plate form, when this carrier bar is bent plate, the assembly opening corresponding with hopper is arranged generally.
The manufacture method of the utility model conveyor chain:
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 the 40Cr band steel to make, carry out modifier treatment through controllable continuous operation stove, its hardness number guarantees that at HRC26-32 its tension and yield strength performance are best.
