Description
Technical field
The utility model relates to roller chain, is a kind of roller chain with buffering chain link.
Background technique
Roller chain is a kind of for transmitting mechanokinetic chain, is widely used in family, industry and farm machinery, comprising conveyor, plotter, printing press, automobile, motorcycle and bicycle.It is generally formed by connecting by inner plate, outer plate, roller, sleeve, connecting pin, and structure is simple, reliable, and transmission of power is efficient.But existing roller chain is normally directly driven by sprocket wheel, in startup moment, if active force is excessive, easily wearing and tearing are caused to roller chain, roller chain fracture even occurs.For this reason, need to be improved existing roller chain.
Model utility content
For overcoming above-mentioned deficiency, the utility model is intended to provide to related domain a kind of roller chain with buffering chain link, makes it solve existing similar roller chain and is starting transmission moment and easily cause the technical problem of wearing and tearing.Its objective is and to be achieved through the following technical solutions.
The roller chain of this band buffering chain link, it comprises inner plate, outer plate, connecting pin, sleeve, roller, and sleeve socket roller is also connected with both sides inner plate interference fit, and connecting pin is through sleeve and two ends are flexibly connected outer plate.In inner plate, outer plate described at least one pair of of this roller chain, the attachment hole that described outer plate coordinates with described connecting pin is kidney-shaped, and connecting pin relative to this attachment hole for being slidably matched, position adjacent with described attachment hole outboard end on described outer plate plate face arranges torsion spring seat, outboard end refers to attachment hole one end near outer plate end, torsion spring seat connection one is with the torsion spring of fork-shaped spring pin, under this torsion spring original state, its fork-shaped spring pin intersects with described connecting pin and pushes against, and makes described connecting pin be positioned at described attachment hole medial extremity.By this kind of structure, make to form an elastic buffer interval between inner plate and outer plate, when roller chain starts, utilize the interaction force of torsion spring and connecting pin, thus make roller chain buffer starting, reduce rigid wearing and tearing.When roller chain drives is stablized, namely identical with the effect of existing roller chain.When roller chain stops transmission, under torsion spring effect, connecting pin, inner plate, outer plate reset.
Described connecting pin one end is provided with spacing head, the other end is provided with pin-and-hole, pin-and-hole connection opening pin, the described fork-shaped spring pin near described connecting pin one end is limited in inside spacing head, and the described fork-shaped spring pin near the described connecting pin the other end is limited in inside described cotter pin.By this structure, ensure that the fork-shaped spring pin of torsion spring is in working position all the time, not easily dislocate
Described connecting pin one end is provided with spacing head, the other end is provided with circlip groove, pin-and-hole, circlip groove connects back-up ring, pin-and-hole connection opening pin, and cotter pin is positioned outside back-up ring, described fork-shaped spring pin near described connecting pin one end is limited in inside spacing head, and the described fork-shaped spring pin near the described connecting pin the other end is limited in inside described back-up ring.By this structure, the fork-shaped spring pin of same guarantee torsion spring is in working position all the time, not easily dislocates.
The utility model by being designed to the one or more pairs of inner plates in roller chain, outer plate with buffer structure, thus makes roller chain buffer starting, reduces rigid wearing and tearing, increases the service life, the problem reduce roller chain fracture, damaging.

Embodiment
Now by reference to the accompanying drawings, the utility model is described as follows.
As shown in Figure 1 and Figure 2, the roller chain of this band buffering chain link comprises inner plate 1, outer plate 2, connecting pin 3, sleeve 6, roller 7, sleeve 6 is socketed roller 7 and is connected with both sides inner plate 1 interference fit, and connecting pin 3 is through sleeve 6 and two ends are flexibly connected outer plate 2.Wherein at least one pair of inner plate 1, outer plate 2, attachment hole that outer plate 2 coordinates with connecting pin 3 201 in kidney-shaped, and connecting pin 3 relative to this attachment hole 201 for being slidably matched.Position adjacent with attachment hole 201 outboard end on outer plate 2 plate face arranges torsion spring that is one-body molded or that be welded and fixed 54, and outboard end refers to attachment hole 201 one end near outer plate 2 end.Torsion spring 54 is located by connecting one with the torsion spring 5 of fork-shaped spring pin 501, and under original state, this fork-shaped spring pin 501 intersects with connecting pin 3 and pushes against, and makes connecting pin 3 be positioned at attachment hole 201 medial extremity.Connecting pin 3 one end is provided with spacing head, and the other end is provided with pin-and-hole 301, pin-and-hole 301 connection opening pin.Fork-shaped spring pin 501 near connecting pin 3 one end is limited in inside spacing head, and the fork-shaped spring pin 501 near connecting pin 3 the other end is limited in inside cotter pin.
As shown in Figure 3, also can be designed to: connecting pin 3 one end is provided with spacing head, the other end is provided with circlip groove, pin-and-hole 301, circlip groove connects back-up ring 8, pin-and-hole 301 connection opening pin, and cotter pin is positioned outside back-up ring 8, the fork-shaped spring pin 501 near connecting pin 3 one end is limited in inside spacing head, and the fork-shaped spring pin 501 near connecting pin 3 the other end is limited in inside back-up ring 8.By this structure, effectively prevent the fork-shaped spring pin 501 of torsion spring 5 from dislocating with connecting pin 3.
