Abstract
The utility model relates to a bipitch roller chain, in particular to a 208B type bipitch roller chain used on a chain transmission device which has long transmission distance and low transmission speed, which solves the defect of insufficient tensile strength of the original 208B type bipitch roller chain. In the bipitch roller chain, the thickness of an inner chain plate is designed to be 1.7 mm, so as to improve the resistance to tension of the inner chain plate and the stability of an inner chain link frame, and also improve the load bearing capability and tensile strength of the whole chain.
Description
Technical field
A kind of double pitch roller chain is specially a kind of 208B type double pitch roller chain that is used on the low chain-driven unit of transmission distance, transmission speed.
Background technique
Existing 208B double pitch roller chain all is to make according to the standard production of GB/T5269 " transmission and conveying bipatch precise roller chain ", form by inner link and outer link, inner link comprises inner plate, roller and axle sleeve, the thickness of inner plate is 1.6 millimeters, the section part area is less sidelong for its aperture axis, for the weak link of chain, fragile.
Summary of the invention
The utility model provides a kind of double pitch roller chain, has solved the shortcoming of original 208B type double pitch roller chain tensile strength deficiency.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of double pitch roller chain is formed by inner link and outer link snapping, and inner link is made up of inner plate, axle sleeve and roller, and the axle sleeve that passes roller is connected between two inner plates, and the thickness of inner plate is 1.7 millimeters.
Inner plate is the weak link of whole roller chain, particularly in the neighboring area in inner plate hole, by being 1.7 millimeters with the inner plate Thickness Design, can improve the stability of the resistance to tension and the inner link framework of inner plate, also improved the ability and the tensile strength of whole chain bearing load simultaneously.
Description of drawings
Fig. 1 is the part schematic representation of inner link and outer link;
Fig. 2 is the structural representation of double pitch roller chain;
Wherein, 1-outer plate, 2-bearing pin, 3-inner plate, 4-roller, 5-axle sleeve.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed specific description.
Double pitch roller chain is made up of inner link and outer link snapping, its structure as shown in Figure 1, outer link comprises outer plate 1 and bearing pin 2, inner link comprises inner plate 3, roller 4 and axle sleeve 5.Bearing pin 2 is connected between two outer plates 1 forms outer link, and axle sleeve 5 passes roller 4 and is connected between two inner plates 3 and forms inner link, and the thickness of inner plate 3 is 1.7 millimeters.
Inner link and outer link circulation snapping are formed meropodium apart from metric system Conveying chains, and whole chain structure as shown in Figure 2.
Inner plate 3 is weak links of roller chain, from tensility, its axis hole periphery is a dangerouse cross-section, the thickness of inner plate 3 has been increased by 0.1 millimeter, not only can improve the tensile strength of inner plate itself, but also can increase the fastness of inner link, and make the inner link framework more stable, main is the tensile load that has improved chain.The design does not influence the installation of axle sleeve 5 and outer plate 3, does not also influence the internal segment inner width of chain, and is convenient for production, practical.
