Abstract
Subtract cross -country motorcycle roller chain of heavy antifatigue, including link joint, round pin axle roller and sleeve, the link joint divide into outer chain plate and inner plate, is equipped with the round pin shaft hole on the link joint, outer chain plate and inner plate are equipped with the NOL ring around being located the round pin shaft hole, and the NOL ring is the round recess around the round pin shaft hole. The utility model discloses a chain is favorable to eliminating aperture punching stress, improves link joint fatigue strength, and non -deformable damages, prolongs long chains's life to material saving, self weight that alleviates whole chain is the gross weight of motorcycle, improves the speed of traveling, reduces the energy consumption simultaneously.
Description
Technical field
The utility model relates to roller chain technical field, particularly Weight reduced type antifatigue cross country motorcycle roller chain.
Background technique
Roller chain is a kind of for transmitting mechanical power chain, and extensive use and family, industry and farm machinery, comprising conveyor, plotter, printing press, automobile, motorcycle and bicycle.It is linked together by a series of short columnar roller, is called the gear drive of sprocket wheel by one, and this is a kind of simple, reliably, and efficient power transmitting deice.
Roller chain for motorcycle often needs good performance.But motorcycle chain general at present after long-term use, owing to being subject to the reason such as effect of stress, wearing and tearing, chain meeting lengthening deformation, easy damage and can not using, needs more to renew chain and causes waste, and in order to ensure the intensity of chain, its weight is general larger, increase motorcycle weight, affect travelling speed, and energy consumption also increases greatly.
Model utility content
The utility model will solve the problem of prior art, provides a kind of firm in structure, antifatigue, lightweight roller chain.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Weight reduced type antifatigue cross country motorcycle roller chain, comprise carrier bar, bearing pin roller and sleeve, carrier bar is divided into outer plate and inner plate, and carrier bar is provided with pin shaft hole, described outer plate and inner plate are positioned at around pin shaft hole and are provided with stress loop, and stress loop is the circle groove around pin shaft hole.Carrier bar material selection high strength alloy material, adopts crystallization of refinement quenching technical, strengthens the shock resistance of chain, and the stress loop on carrier bar adopts impact style to be formed, and eliminates aperture punching stress, improves carrier bar fatigue strength.Bearing pin adopts special chromaking process, and surface hardness is very high, greatly improves chain wear-resisting property, extends the working life of chain.Sleeve two ends adopt extruding counter-boring techniques, strengthen the link fastness of sleeve and inner plate, improve internal segment extrusion pressure simultaneously, strengthen chain link fatigue strength.
Preferably, described outer plate and inner plate are positioned at two sides corresponding position around pin shaft hole and are all provided with stress loop.The stress loop of outer plate and the cooperation of bearing pin, the stress loop of inner plate and the cooperation of sleeve, improve the cooperation fatigue strength of these two aspects structure.
Preferably, described stress loop is provided with two circles.
Preferably, described outer plate and inner plate neutral position are provided with circular hole.Not affect premised on whole chain usability, the mode of punching is adopted to be formed.
Preferably, described Circularhole diameter is 2mm.
The beneficial effects of the utility model are: be conducive to eliminating aperture punching stress, improve carrier bar fatigue strength, not easily deformed damaged, extend the working life of chain, and save material, alleviate the own wt of whole chain and the gross weight of motorcycle, improve travelling speed, reduce energy consumption simultaneously.

Fig. 1 is front view of the present utility model.
Fig. 2 be Fig. 1 overlook partial sectional view.
Fig. 3 is the structural representation of the utility model carrier bar.
Fig. 4 is the transverse cross-sectional view of the utility model carrier bar.
In figure: 1, outer plate; 2, inner plate; 3, bearing pin; 4, roller; 5, sleeve; 6, pin shaft hole; 7, stress loop; 8, circular hole.
Embodiment
Below by embodiment and accompanying drawing, the utility model is further described.
Mode of execution is: composition graphs 1-4, Weight reduced type antifatigue cross country motorcycle roller chain, comprise carrier bar, bearing pin 3 roller 4 and sleeve 5, carrier bar is divided into outer plate 1 and inner plate 2, carrier bar is provided with pin shaft hole 6, is positioned at punching press stress loop 7 around pin shaft hole 6 at described outer plate 1 and inner plate 2, and stress loop 7 is the circle groove around pin shaft hole 6, and stress loop 7 is all established on the two sides of outer plate 1 and inner plate 2, and the stress loop 7 often located is two circles; In addition, under the prerequisite not affecting motorcycle chain overall performance, in the neutral position of outer plate 1 and inner plate 2, rush a circular hole 8, diameter is 2mm.
By the Rings Roller Chains that said structure forms, fatigue resistance is good, not easily deformed damaged, long service life, and saves material, alleviates the gross weight of own wt and motorcycle, improves travelling speed, reduces energy consumption simultaneously.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, the utility model may be used on similar product, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
