Abstract
The utility model provides a long-pitch metric chain, which at least comprises inner links and outer links, wherein the inner links and the outer links are sequentially connected in series. Each inner link comprises two inner link plates, two sleeves installed between the two inner link plates and rollers sheathed on the sleeves, and each outer link comprises two outer link plates and two pin shafts installed between the two outer link plates. In the adjacent inner link and outer link, one sleeve of the inner link is sheathed on one pin shaft of the outer link. The inner width of the inner links is 25.7-26mm, the diameter of the pin shafts is 14.27-14.29mm, and the height of the inner link plates and the outer link plates is 40-40.30mm. The long-pitch metric chain increases the inner width of the inner links and increases the diameter of the pin shafts and the height of the inner and outer link plates at the same time, so that the tensile load of the whole chain is increased from 55.6KN to 222.4KN, the tensile strength is greatly increased, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of meropodium apart from metric system chain, is specially a kind ofly to be used for S type meropodium on the low chain-driven unit of transmission distance, transmission speed apart from metric system chain.
Background technique
Existing meropodium is in metric system chain, and close with the utility model and pitch is that 50 millimeters meropodium is 18 millimeters apart from the internal segment inner width of metric system chain, and the height of inner plate and outer plate is 21 millimeters, and the diameter of bearing pin is 7 millimeters.This chain is thinner because of thickness of link plates, and boundary dimension is less, and bearing pin is thinner, so bearing capacity is less, and antifatigue and wear resistance are relatively poor, impact with the oscillating load operating mode under be easy to yield deformation and crack to cause chain to lose efficacy, working life is shorter.
Summary of the invention
The utility model provides a kind of meropodium apart from metric system chain, on the basis that does not change existing pitch, has strengthened the tensile strength of chain greatly, has prolonged working life, working stability, safe and reliable.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of meropodium is apart from metric system chain; At least comprise the inner link and the outer link of serial connection successively; Inner link comprises two inner plates and is installed on two sleeves between two inner plates, and is enclosed within the roller on the sleeve, and outer link comprises two outer plates and two bearing pins between two outer plates; Inner link jacket casing is on a bearing pin of outer link in adjacent inner link and the outer link; The inner width of inner link is 25.7～26 millimeters, and the diameter of bearing pin is 14.27～14.29 millimeters, and the height of inner plate and outer plate is 40～40.30 millimeters.
The inner width of inner link is 25.7 millimeters; The diameter of bearing pin is 14.29 millimeters; The height of inner plate and outer plate is 40 millimeters.
This meropodium under the situation that does not change pitch, with the internal segment inner width increasing of chain, has increased the diameter of bearing pin apart from metric system chain simultaneously; Strengthened the height of interior outer plate; The tensile load of therefore whole chain is increased to 222.4KN by original 55.6KN, stable work in work, and prolong working life.
Description of drawings
The meropodium that Fig. 1 provides for the utility model is apart from the structural representation of metric system chain;
Fig. 2 is the plan view of Fig. 1;
Among the figure, 1-outer plate, 2-inner plate, 3-bearing pin, 4-sleeve, 5-roller.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The meropodium that the utility model provides is as depicted in figs. 1 and 2 apart from the structure of metric system bar Conveying chains; By the inner link and the outer link of serial connection are formed successively; Inner link comprises inner plate 2, roller 5 and sleeve 4; Sleeve 4 passes roller 5 and is fixed between two inner plates 2, and the inner width of inner link is 25.7～26 millimeters, adopts 25.7 millimeters of optimum sizes in the present embodiment; Outer link comprises outer plate 1 and is fixed in the bearing pin 3 between two outer plates that the diameter of bearing pin 3 is 14.27～14.29 millimeters, adopts 14.29 millimeters of optimum diameters in the present embodiment; The height of inner plate 2 and outer plate 1 is 40～40.30 millimeters, adopts 40 millimeters of optimum heights in the present embodiment.
Inner link jacket casing is on a bearing pin of outer link in adjacent inner link and the outer link, and inner link and outer link are connected in series successively, forms whole chain.
This meropodium strengthens apart from the internal segment inner width of metric system chain with chain, has increased the diameter of bearing pin simultaneously, has strengthened the height of interior outer plate, and the tensile load of therefore whole chain is increased to 222.4KN by original 55.6KN, and tensile strength improves greatly, has prolonged working life.
