Abstract
The utility model provides a chain for a chain coupler, wherein the chain at least comprises inner chain links, outer chain links and intermediate chain plates positioned between two inner chain links; the outer chain links comprise two outer chain plates and a pin shaft fixed between the two outer chain plates; the inner chain links comprise two inner chain plates and a sleeve installed between the two inner chain plates; a roller is sleeved on the sleeve; the pin shaft penetrates through the sleeve of the two inner chain links and the intermediate chain plate; the thicknesses of the intermediate chain plates are 6.24-6.4mm; and thicknesses of the inner chain plates and the outer chain plates are 3.12-3.2mm. According to the chain for the chain coupler, the two intermediate chain plates are designed into an integral intermediate chain plate, thus the torsional-resistant strength and abrasion resistance of the chain are improved greatly; and at the same time, the thicknesses of the inner chain plates and the outer chain plates are increased, thus the whole chain operates more stably under the working conditions of great torque and impact.
Description
Technical field
The utility model relates to a kind of chain that is used for chain coupling, and the model that is specially on a kind of chain-driven unit that is installed in coupling is the double strand chain of 12A-2.
Background technique
The used chain of existing chain coupling is all made according to the GB/T1243 standard design, adopts short pitch double strand chain form.Existing 12A-2 double strand chain is light-duty roller chain, and its pitch P is 19.05 millimeters.In the actual production using process, because intermediate plate is two, its thinner thickness in the existing coupling chain; Antitorque poor performance in the wrong; Because the thickness of inner plate and outer plate is also thinner, be 2.4 millimeters again, therefore have greater impact, bigger vibration and transmitting under the situation than high pulling torque; This 12A-2 chain is prone to fatigue failure takes place, and working life is low.The principal mode that lost efficacy is the heavy wear distortion even the fracture of chain, so this kind chain is difficult to the transmission work of competent high pulling torque.
Summary of the invention
The utility model provides a kind of chain that is used for chain coupling, has solved traditional 12A-2 chain shortcomings such as fatigue failure, working life be low be prone to take place in the course of the work.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of chain that is used for chain coupling; At least comprise inner link, outer link and the intermediate plate between two inner links, outer link comprises two outer plates and is fixed in the bearing pin between two outer plates that inner link comprises two inner plates and is installed on the sleeve between two inner plates; Be with roller on the sleeve; Bearing pin passes sleeve and intermediate plate of two inner links, and the thickness of intermediate plate is 6.24～6.4 millimeters, and the thickness of inner plate and outer plate is 3.12～3.2 millimeters.
The thickness of intermediate plate is 6.4 millimeters; The thickness of inner plate is 3.2 millimeters, and the thickness of outer plate is 3.2 millimeters.
The chain that is used for chain coupling that the utility model provides is designed to a whole intermediate plate with two intermediate plates, makes the anti-twist intensity and the wear resistance of chain improve greatly; Simultaneously with the enlarged in thickness of inner plate and outer plate, make whole chain at high pulling torque, more stable work under the operating mode of impact is arranged.
Description of drawings
The overall structure schematic representation of the 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 structure of the 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, and sleeve 4 is installed between two inner plates 3 forms inner link, and bearing pin 1 is fixed between two outer plates 2 forms outer link.Two inner links are arranged side by side; 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 6.24～6.4 millimeters; Adopt 6.4 millimeters of optimum thicknesses in the present embodiment, as shown in Figure 2.The thickness of inner plate is 3.12～3.2 millimeters, adopts 3.2 millimeters of optimum thicknesses in the present embodiment; The thickness of outer plate is 3.12～3.2 millimeters, adopts 3.2 millimeters of optimum thicknesses in the present embodiment.
The chain that is used for chain coupling that the utility model provides is designed to a whole intermediate plate with two intermediate plates, makes the anti-twist intensity and the wear resistance of chain improve greatly; Simultaneously with the enlarged in thickness of inner plate and outer plate, make whole chain at high pulling torque, more stable work under the operating mode of impact is arranged.
