Abstract
The invention discloses a chain with a flanged outer chain sheet. The chain is formed by connecting a set of serial connection units in series, each serial connection unit comprises a chain roller, inner chain sheets, outer chain sheets and a pin shaft, the inner chain sheets are arranged on two sides of the chain roller, the outer chain sheets are arranged on the outer sides of the inner chain sheets, the pin shaft connects the chain roller, the inner chain sheets and the outer chain sheets, and a flange is arranged on a hole of each outer chain sheet, thus the strengths of the outer chain sheets are increased and the material cost is reduced. The outer chain sheets and the inner chain sheets can share one set of production equipment so as to reduce the manufacturing cost; in addition, a lateral arc chamfer is designed in a connecting hole, thus the outer chain sheets can be greatly prevented from being broken due to being crushed during production and assembly of the chain, and the production efficiency is improved.
Description
Technical field
The present invention relates to the flanged chain of a kind of outer chain sheet.
Background technique
Bicycle chain mainly by chain roll, interior Chain link for chain grate, outer chain sheet and bearing pin are formed, and are the vitals of realizing wheel drive, therefore, for having relatively high expectations of chain intensity; At present for reaching this requirement, the mode that generally adopts the chain sheet of chain to thicken, but so caused the huge consumption of resource, increased cost greatly; Simultaneously each outer chain sheet aperture is right angle type, and outer chain sheet is wounded by bearing pin easily when chain assemble, thereby causes the bearing pin inlay resultant force seriously to reduce down and the generation chain phenomenon of dying for the sake of honour; Be badly in need of a kind of chain that can address the above problem for this reason.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention proposes the flanged chain of a kind of outer chain sheet, improves chain intensity, reduces cost, and enhances productivity.
Technological scheme: for solving the problems of the technologies described above, this chain comprises that chain rolls, and is arranged on the inner chain sheet that chain rolls both sides; Be arranged on the outer chain sheet in the inner chain sheet outside; With the bearing pin that said chain rolls, inner chain sheet, outer chain sheet connect, the place is provided with flange in said outer chain sheet aperture, the inboard chamfering that forms in the aperture.
Beneficial effect: the flanged chain of a kind of outer chain sheet of proposition of the present invention, the place is provided with flange in said outer chain sheet aperture, reduces cost of material when increasing outer chain sheet intensity; Can with the shared same set of manufacturing mechanism of inner chain sheet, reduced manufacture cost; In connecting the aperture, carry out the design of side arc angling, it is wounded to make chain in the production and assembly process, can significantly reduce outer chain sheet, enhances productivity.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is connected in series the modular construction exploded view for the present invention;
Fig. 3 is an outer chain sheet structural representation of the present invention;
Fig. 4 is a chamfering structure schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Like Fig. 1, shown in 2; This chain comprises that one group of serial connection unit composes in series, and each serial connection unit comprises that chain rolls 1, is arranged on the inner chain sheet 2 that chain rolls 1 both sides; Be arranged on the outer chain sheet 3 in inner chain sheet 2 outsides, with the bearing pin 4 that said chain rolls 1, inner chain sheet 2, outer chain sheet 3 connect.
Like Fig. 1, as described in 3, this outer chain sheet 3 comprises first joint 7 and second joint 8, is respectively equipped with attachment hole thereon, and the place vertically is provided with flange 5 in described connection aperture, has increased the intensity of chain greatly.
As shown in Figure 4, be provided with arc angling 6, when outer chain sheet is installed with the flange 5 reverse inboards, aperture that are connected; Bearing pin 4 can insert in the attachment hole along chamfering 6 smoothly; Reduced because of the bearing pin bump causes the situation of outer chain sheet damage and taken place, improved packaging efficiency simultaneously, increased output.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be considered as protection of the present invention.
Claims (2)
