Abstract
The utility model relates to a reinforced type double-pitch roller chain, in particular to a 220A type double-pitch roller chain used on a chain transmission device with long transmission distance and low transmission speed. Through increasing the thickness and the dimension of inner and outer chain plates and increasing the diameter of a pin shaft, the roller chain overcomes the defects of smaller bearing capacity, poorer fatigue resistance and abrasion resistance, shorter service life and the like of the original 220A type double-pitch roller chain; and the reinforced type double-pitch roller chain is stable to work and is durable under working conditions of impact and vibration load.
Description
Technical field
A kind of reinforced double pitch roller chain is specially a kind of 220A type double pitch roller chain that is used on the low chain-driven unit of transmission distance, transmission speed.
Background technique
Existing 220A double pitch roller chain all is to make according to the standard production of GB/T5269 " transmission and conveying bipatch precise roller chain ", its pin diameter is the 9.51-9.53 millimeter, outer plate thickness is 4 millimeters, highly be 30 millimeters, waist sizes is 20 millimeters, inner plate thickness is 4 millimeters, highly is 30 millimeters, and waist sizes is 20 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
Shortcomings such as the utility model provides a kind of reinforced double pitch roller chain, and it is less to have solved original 220A double pitch roller chain bearing capacity, and antifatigue and wear resistance are relatively poor, and working life is short, working stability under impact and oscillating load operating mode is durable in use.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of reinforced double pitch roller chain, form by inner link and outer link, wherein the inner plate thickness of inner link is 4.5～4.8 millimeters, highly be 30.5～32 millimeters, waist sizes is 23～26 millimeters, and the outer plate thickness of outer link is 4.5～4.8 millimeters, highly is 30.5～32 millimeters, waist sizes is 23～26 millimeters, and the diameter of bearing pin is 9.8～10 millimeters.
This reinforced double pitch roller chain is by the thickness and the boundary dimension of outer plate in increasing, the torque value and the bearing capacity of chain have been improved, the diameter of overstriking bearing pin has improved its wear resistance, and the tensile load of chain is increased to about 10T by original 8.843T, and increase working life.

Fig. 2 is the overall structure schematic representation of chain;
Among the figure, 1-inner plate, 2-roller, 3-axle sleeve, 4-outer plate, 5-bearing pin.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
A kind of reinforced double pitch roller chain is made up of inner link and outer link, and as shown in Figure 1, inner link comprises inner plate 1, axle sleeve 3 and roller 2, and outer link comprises outer plate 4 and bearing pin 5.Axle sleeve 3 passes roller 2 and is fixed between two inner plates 1, inner plate 1 thickness is 4.5～4.8 millimeters, adopt 4.65 millimeters of optimum sizes in the present embodiment, highly be 30.5～32 millimeters, adopt 31 millimeters of optimum sizes in the present embodiment, waist sizes is 23～26 millimeters, adopts 24.8 millimeters of optimum sizes in the present embodiment.Bearing pin 5 is between two outer plates 4, the diameter of bearing pin 5 is 9.8～10 millimeters, adopt 9.8 millimeters of optimum sizes in the present embodiment, outer plate 4 thickness are 4.5～4.8 millimeters, adopting 4.65 millimeters of optimum sizes in the present embodiment, is 30.5～32 millimeters highly, adopts 31 millimeters of optimum sizes in the present embodiment, waist sizes is 23～26 millimeters, adopts 24.8 millimeters of optimum sizes in the present embodiment.
One end of bearing pin 5 is pressed in outer plate 4 axis holes, the other end passes the axle sleeve 3 of inner link, successively inner link and the such intercycle of outer link are put on, reinstall the outer plate 4 of another side, at last chain hinge pin is appeared and die, promptly finish the assembling of this reinforced double pitch roller chain, whole chain as shown in Figure 2.
Double pitch roller chain is widely used in the long and lower occasion of transmission speed of transmission distance.In actual application, transmission speed just rises and falls greatly, and is accompanied by impact and vibration, applying working condition more complicated.By the thickness and the increase profile of outer plate in improving, can significantly improve the ability of its bearing load, strengthen the anti-surrender ability and the fatigue strength of carrier bar and chain integral body.Bearing pin also is a whole chain bearing capacity of influence and a shock proof key factor, by the overstriking pin diameter, has improved the wear resistance and the tensile strength of whole chain.
