Detailed description of the invention
Referring to figs. 1 through Fig. 3, carrier bar is described further.
Embodiment 1: a kind of carrier bar, with reference to Fig. 1, including carrier bar plate body 2.The most common carrier bar plate body 2 is a straight plate slice-shaped part, and this sheet parts is provided only with the hole being hinged between carrier bar, when by foreign impacts, is easily deformed；And this carrier bar is only capable of protecting chain both sides the most affected with dust；Introduced contaminants still can be infected with in gap between roller, thus affects driving-chain motion on drive.
With reference to Fig. 1, the head end 11 of this carrier bar and tail end 12 are respectively provided with the installing hole 8 and hinge hole 9 being hinged with other carrier bars.Head end 11 and tail end 12 are positions hinged between the chain link of chain, and the head end 11 of front shot of a cable joint is hinged with the tail end 12 of later section chain link, thus forms complete driving-chain.
With reference to Fig. 2, both sides, hinge hole 9 outer ring are provided with limited block 10.The chain link head and the tail of driving-chain interlock, and the limited block 10 of tail end 12 agrees with mutually with the hole shape in the head end 11 of later section chain link；Hinged jointed shaft 91 carries out spacing for the most limited piece 10, and after carrier bar plate body 2 increases with bearing pin contact area, steadiness improves, and improves quality of fit on the basis of hinged.
With reference to Fig. 1 and Fig. 2, the carrier bar plate body 2 in this utility model is provided with the rectangular channel 3 between head end 11 and tail end 12, needed raw material when rectangular channel 3 had both decreased production, can reduce again the impact of outer bound pair carrier bar plate body 2.Unnecessary lubricating oil can also be spilt by rectangular channel 3 simultaneously, makes the lubricating oil in actuating device be in suitable amount.
Rectangular channel 3 area is big, almost occupies on carrier bar plate body 2 all areas in addition to hinge hole 9, therefore its intensity is low, is easily deformed.In order to improve the intensity of carrier bar plate body 2, it is ensured that transmission effect, with reference to Fig. 2, this utility model is provided with in rectangular channel 3 support chip 7 for supporting 3 two long limits of rectangular channel at equal intervals.
With reference to Fig. 2, support chip 7 and carrier bar plate body 2 junction are provided with rounding, and rounding increases support chip 7 and the contact area of carrier bar plate body 2, improve the stability between support chip 7 and carrier bar plate body 2, further increase the intensity of carrier bar plate body 2.
With reference to Fig. 1, the carrier bar plate body 2 between installing hole 8 and hinge hole 9 is provided with the axis of the baffle plate 4 extended laterally out, the bearing of trend on baffle plate 4 and installing hole 8 and hinge hole 9 in the same direction.Baffle plate 4 is arranged between head end 11 and tail end 12；Head end 11 and tail end 12 are positions hinged between the chain link of chain.The connected mode of driving-chain and drive is mostly driving-chain and discharges in drive edge, therefore on the chain link of driving-chain space between the bearing pin of two ends 12 for coordinating with the gear teeth.The impurity such as carrier bar exists space with the drive place of cooperation, if this gap is not provided with dust prevention, is directly exposed in air, the batting of external environment are stuck in space after easily being adhered by lubricating oil, and affecting transmission efficiency even can not transmission.After the carrier bar plate body 2 part in addition to two ends 12 is covered by the size of baffle plate 4, it is possible to by isolated from contaminants outside, it is ensured that the effective cooperation between drive and driving-chain.
Baffle plate 4 and carrier bar plate body 2 are integrated setting.Combination is assembled into chain needs substantial amounts of carrier bar, and the baffle plate 4 and the carrier bar plate body 2 that are wholely set are the most easily manufactured, it is possible to completes stamping-out by same composite punching machine and works, punching press one-shot forming, and production efficiency is high, it is possible to adapt to produce in enormous quantities.
With reference to Fig. 1, described baffle plate 4 is provided with through hole 6, needs lubricating oil to ensure smooth movements during driving-chain work, and the through hole 6 on baffle plate 4 is easy to lubricating oil and is instilled lubricating transmission wheel and roller, and protection actuating device is not affected by corrosion.
With reference to Fig. 1, described baffle plate 4 is provided with reinforcement 5, and the two ends of reinforcement 5 connect carrier bar plate body 2 and baffle plate 4 respectively.Individually baffle plate semi-finals degree is not high enough, and after punching, intensity reduces again, in order to ensure transmission quality, arranges reinforcement 5 to improve baffle plate semi-finals degree, the deformation due to foreign impacts of anti-baffle plate 4.
Embodiment 2: a kind of chain, with reference to Fig. 3, the present embodiment is with the difference of embodiment 1, and the baffle plate 4 in the present embodiment and carrier bar plate body 2 are detachable setting.When some carrier bars are end to end be hinged to a complete driving-chain after, this complete driving-chain is arranged on drive, general uses two drives by its tensioning；If chain self is from great, or the distance transmission it cannot be guaranteed that chain is tensioned between two drives, regulating wheel is then set on chain, regulating wheel is preferably provided at chain and deviates from drive side, dismountable baffle plate 4 can be removed in case baffle plate 4 hinders regulating wheel to rotate when arranging regulating wheel.Therefore the carrier bar range of demountable structure is wider.
Above-mentioned specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
