Abstract
An enhanced bipitch roller chain is particularly a 224A typed bipitch roller chain for a chain transmission device long in transmission distance and low in transmission speed, and at least comprises an inner chain link and an outer chain link. The enhanced bipitch roller chain is characterized in that thickness of each inner chain plate ranges from 5.5mm to 5.6mm, height of the inner chain plate ranges from 35.8mm to 37.8mm, waist size of the inner chain plate ranges from 28mm to 35mm, thickness of an outer chain plate ranges from 5.5mm to 5.6mm, height of the outer chain plate ranges from 30.6mm to 37.8mm, waist size of the outer chain plate ranges from 22.8mm to 35mm, and diameter of each pin ranges from 12.5mm to 13mm. by enlarging thicknesses of the inner chain plates and the outer chain plates, sizes of the inner china plates and the outer chain plates, and diameters of the pins, the shortages of lower bearing capacity, poorer fatigue resistance, poorer wear resistance, short service life and the like of an original 224A bipitch roller are overcome, and the enhanced bipitch roller chain is stable in operation under impact and vibration loading conditions, and is durable.
Description
Technical field
A kind of reinforced double pitch roller chain is specially a kind of 224A type double pitch roller chain that is used on the low chain-driven unit of transmission distance, transmission speed.
Background technique
Existing 224A double pitch roller chain all is to make according to the standard production of GB/T5269 " transmission and conveying bipatch precise roller chain ", its outer plate thickness is 4.8 millimeters, highly be 30.6 millimeters, waist sizes is 22.8 millimeters, inner plate thickness is 4.8 millimeters, highly be 35.8 millimeters, waist sizes is 28 millimeters, and pin diameter is the 11.08-11.1 millimeter.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 224A 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 5.5～5.6 millimeters, highly be 35.8～37.8 millimeters, waist sizes is 28～35 millimeters, and the outer plate thickness of outer link is 5.5～5.6 millimeters, highly is 30.6～37.8 millimeters, waist sizes is 22.8～35 millimeters, and the diameter of bearing pin is 12.5～13 millimeters.
This reinforced double pitch roller chain has improved bearing capacity, antifatigue and the wear resistance of chain by thickness, increase profile and the overstriking pin diameter of outer plate in increasing, and increase working life.

Fig. 2 is the overall structure schematic representation after the chain installation;
Among the figure, 1. inner plate, 2. roller, 3. bearing housing, 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, bearing housing 3 and roller 2, and outer link comprises outer plate 4 and bearing pin 5.Bearing housing 3 passes roller 2 and is fixed between two inner plates 1, inner plate 1 thickness is 5.5～5.6 millimeters, adopt 5.55 millimeters of optimum sizes in the present embodiment, highly be 35.8～37.8 millimeters, adopt 36.8 millimeters of optimum size height in the present embodiment, waist sizes is 28～35 millimeters, adopts 31.5 millimeters of optimum sizes in the present embodiment.Bearing pin 5 is between two outer plates 4, the diameter of bearing pin 5 is 12.5～13 millimeters, adopt 12.75 millimeters of optimum sizes in the present embodiment, outer plate 4 thickness are 5.5～5.6 millimeters, adopting 5.55 millimeters of optimum sizes in the present embodiment, is 30.6～37.8 millimeters highly, adopts 34.2 millimeters of optimum sizes in the present embodiment, waist sizes is 22.8～35 millimeters, adopts 28.9 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 bearing housing 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 tensile strength of whole chain.
