Abstract
The utility model provides a double-row chain for a chain coupling, which at least comprises inner chain sections, outer chain sections and a middle chain plate. A roller is sleeved on a sleeve, the sleeve is installed between two inner chain plates to form the inner chain sections, and the middle chain plate is located between the two inner chain sections. A pin shaft is connected between two chain plates. The pin shaft penetrates through the sleeve of the two inner chain sections and the middle chain plate. The thickness of the middle chain plate ranges from 8.0 mm to 8.4 mm, the height of the middle chain plate ranges from 29 mm to 31 mm, and the width of the waist of the middle chain plate ranges from 20.5 mm to 23.5 mm. The pin shaft and the outer chain plates are fixed by four-corner rivets, thereby enhancing firmness of connection between the pin shaft and the outer chain plates. Two middle chain plates are designed to be a whole middle chain plate, thereby increasing the height of the middle chain plate simultaneously, improving torsional strength and corrosion resistance of the chain, and greatly prolonging service life of the chain.
Description
Technical field
The utility model relates to a kind of double strand chain that is used for chain coupling, and the model that is specially on a kind of chain-driven unit that is used for coupling is the double strand chain of H20A-2.
Background technique
The used chain of existing chain coupling all adopts short pitch double strand chain form.In use there are many defectives in this kind chain coupling: because chain coupling is an active rotation; Drive another axle rotation through double strand chain; Chain is different under in such cases force-bearing situation and conventional state, has born bigger torque load.Intermediate plate is two in existing coupling chain, thinner thickness, and antitorque poor performance in the wrong is simultaneously because the height of intermediate plate is pressed standard design, the impact force that incompatibility is certain.Because the riveted in the whole chain is 2 rivetings, this situation should be used for the simple tension load again; And in use both there had been tensile load in chain on the coupling, had torsional buckling power load again, can cause riveted point loosening too early.Because above-mentioned defect influence, the intensity antitorque in the wrong and the wear resistance of whole chain are relatively poor, and the working life of chain is shorter.
Summary of the invention
The utility model provides a kind of double strand chain that is used for chain coupling, has solved existing coupling chain tensile strength and wear resistance is relatively poor, working life is short shortcoming.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of double strand chain that is used for chain coupling comprises inner link, outer link and intermediate plate at least, and roller sleeve is on sleeve; Sleeve is installed between two inner plates forms inner link, and intermediate plate is connected with bearing pin between two outer plates between two inner links; Bearing pin passes the sleeve and the intermediate plate of two inner links; The thickness of intermediate plate is 8.0～8.4 millimeters, and the height of intermediate plate is 29～31 millimeters, and intermediate plate waist width is 20.5～23.5 millimeters.
The thickness of intermediate plate is 8.2 millimeters, and the height of intermediate plate is 30 millimeters, and intermediate plate waist width is 22 millimeters; The two ends of bearing pin are fixed on the outer plate through four jiaos of dies.
This is used for the double strand chain of chain coupling, and two intermediate plates are designed to a whole intermediate plate, has also increased the height of intermediate plate simultaneously, makes the anti-twist intensity and the wear resistance of chain improve greatly; The two ends of bearing pin adopt four jiaos of dies and outer plate to fix simultaneously, have strengthened the soundness that connects between bearing pin and the outer plate, have improved the working life of chain.
Description of drawings
The overall structure schematic representation of the double strand chain that is used for chain coupling that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of intermediate plate;
Among the figure: 1-bearing pin, 2-outer plate, 3-inner plate, 4-sleeve, 5-roller, 6-intermediate plate.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The overall structure of the double strand chain that is used for chain coupling that the utility model provides is as shown in Figure 1; Form by inner link, outer link and intermediate plate 6; Roller 5 is enclosed within on the sleeve 4; Sleeve 4 is installed on 3 composition inner links of two inner plates, and bearing pin 1 is fixed between two outer plates 2 forms outer link, and the two ends of bearing pin 1 are fixed on the outer plate 2 through four jiaos of dies in the present embodiment.Two inner links are arranged side by side, and intermediate plate 6 is between two inner links that are arranged side by side, and the bearing pin 1 of outer link passes two inner links and intermediate plate 6 side by side, and the thickness of intermediate plate 6 is 8.0～8.4 millimeters, adopts 8.2 millimeters of optimum thicknesses in the present embodiment; The height of intermediate plate is 29～31 millimeters, adopts 30 millimeters of optimum heights in the present embodiment, and the waist width of intermediate plate is 20.5～23.5 millimeters, adopts 22 millimeters of best waist width in the present embodiment, and is as shown in Figure 2.
The double strand chain that is used for chain coupling that the utility model provides adopts four jiaos of dies to fix between bearing pin and the outer plate, strengthened the soundness that connects between bearing pin and the outer plate; Again two intermediate plates are designed to a whole intermediate plate, have also increased the height of intermediate plate simultaneously, make the anti-twist intensity and the wear resistance of chain improve greatly, also prolong greatly the working life of chain.
