參閱圖3~6,本新型鏈條之一第一實施例,包含一個鏈條本體3,及一個接頭單元4。Referring to Figures 3-6, a first embodiment of the novel chain includes a chain body 3 and a joint unit 4.

該鏈條本體3沿著長度方向圍繞成一個環圈形,並包括兩個分別位在相反兩端的鏈端單元31,及數個彼此串連樞接且連接於該等鏈端單元31之間的串接單元32。以下僅就該等鏈端單元31相鄰的部位來說明,每一個鏈端單元31都界定出一個位於鄰近另一個鏈端單元31之一端部的軸孔311,就構造而言,每一個鏈端單元31具有兩片相間隔的鏈片312、一個兩端分別穿設連接該等鏈片312且設置該軸孔311的襯套313,及一個可轉動地套設在該襯套313外圍且位於該等鏈片312間的滾子314。由於該鏈條本體3的結構類型眾多,且其並非本第一實施例之設計重點,所以實施時不以上述類型為限,在此也不再說明其詳細構造。The chain body 3 is formed in a ring shape along the length direction, and includes two chain end units 31 respectively located at opposite ends, and a plurality of chain end units 31 connected in series with each other and connected between the chain end units 31. The unit 32 is connected in series. Hereinafter, only the portions adjacent to the chain end units 31 will be described. Each of the chain end units 31 defines a shaft hole 311 located at one end of the other chain end unit 31. In terms of construction, each chain The end unit 31 has two spaced-apart chain pieces 312, one end of which is respectively connected with a bushing 313 connecting the chain pieces 312 and provided with the shaft hole 311, and a rotatably sleeved on the periphery of the bushing 313 A roller 314 is located between the links 312. Since the chain body 3 has a large number of structural types, and it is not the design focus of the first embodiment, it is not limited to the above types when implemented, and the detailed configuration thereof will not be described here.

該接頭單元4將該鏈條本體3之該等鏈端單元31銜接在一起,該接頭單元4包括一片對應跨設於該等鏈端單元31之一側的連接片41、一片對應跨設在該等鏈端單元31遠離該連接片41之一側的接頭片42、兩支對應串接該連接片41、該等鏈端單元31與該接頭片42的連接軸43,及一片位於該接頭片42遠離該等鏈端單元31之一側且扣接該等連接軸43的扣接片44。The connector unit 4 connects the chain end units 31 of the chain body 3 together, and the connector unit 4 includes a connecting piece 41 corresponding to one side of the chain end unit 31, and a piece correspondingly spans the The connecting end piece unit 31 is away from the tab piece 42 on one side of the connecting piece 41, two connecting shafts 41 corresponding to the connecting piece 41, the chain end unit 31 and the connecting piece 42 are located, and one piece is located on the connecting piece 42 is fastened from one side of the chain end unit 31 and fastens the fastening tabs 44 of the connecting shafts 43.

該連接片41具有兩個相間隔之套孔411。該接頭片42具有一個片本體421,及兩個套環422。該片本體421具有兩個相間隔的環端部423,及一個中介連接該等環端部423的連接部424。每一個環端部423圈圍界定出一個嵌孔425,並具有一個呈圓弧形且與該嵌孔425同圓心地位於外周緣的環端緣426。該連接部424具有兩個相間隔且相向凹弧的連接緣427,每一個連接緣427連接該等環端緣426相鄰之一端,該等連接緣427之間的距離由兩側往中央逐漸縮短。該片本體421還具有兩個相間隔的側面428。The connecting piece 41 has two spaced-apart holes 411. The tab 42 has a sheet body 421 and two collars 422. The sheet body 421 has two spaced apart loop ends 423 and a connecting portion 424 that mediates the loop ends 423. Each of the loop ends 423 defines a bore 425 and has a ring end edge 426 that is arcuate and centrally located with the bore 425 at the outer periphery. The connecting portion 424 has two connecting edges 427 which are spaced apart and opposed to each other, and each connecting edge 427 connects one end adjacent to the end edge 426 of the ring. The distance between the connecting edges 427 gradually increases from the two sides toward the center. shorten. The sheet body 421 also has two spaced apart sides 428.

每一個套環422緊配合地嵌設於該片本體421各別之嵌孔425中,並圈圍界定出一個穿孔429,需說明的是,在相同的接頭片42規格下,本第一實施例之該套環422的穿孔429尺寸等於圖1接頭片22之穿孔221尺寸。該套環422的厚度等於各別之連接軸43直徑的20%±5%,該連接軸43直徑亦為該鏈條本體3之串接單元32各別之軸桿的規格尺寸,若是該套環422的厚度小於該連接軸43直徑的20%-5%,則製造良率低且使用壽命短,若是該套環422的厚度大於該連接軸43直徑的20%+5%,則會相對縮減每一個環端部423的面積,反而弱化該片本體421特別是該等環端部423的強度,該套環422的硬度大於該片本體421的硬度,在本第一實施例中,該套環422是由低碳合金鋼製成,製法可以採用粉末冶金成形,當然其材料及製法不以此為限,例如也可以使用類似該襯套313的材料,或是以合適尺寸的襯套313直接替換。該套環422具有兩個相間隔且分別對應該等側面428的端面420,每一個端面420與該片本體421相對應之側面428齊平地位於同一平面上。在製造上,該片本體421及該等套環422是各自製造成形後,再將該等套環422緊塞入該片本體421中。Each of the collars 422 is tightly fitted into each of the insert holes 425 of the sheet body 421 and defines a perforation 429. It should be noted that the first embodiment is implemented under the same tab 42 specifications. For example, the size of the through hole 429 of the collar 422 is equal to the size of the through hole 221 of the tab 22 of FIG. The thickness of the collar 422 is equal to 20%±5% of the diameter of the respective connecting shafts 43. The diameter of the connecting shaft 43 is also the size of the shaft of each of the series units 32 of the chain body 3. If the collar is The thickness of 422 is less than 20%-5% of the diameter of the connecting shaft 43, the manufacturing yield is low and the service life is short. If the thickness of the collar 422 is greater than 20%+5% of the diameter of the connecting shaft 43, the thickness is relatively reduced. The area of a ring end portion 423, on the contrary, weakens the strength of the sheet body 421, particularly the ring end portion 423, the hardness of the collar 422 is greater than the hardness of the sheet body 421. In the first embodiment, the collar 422 is made of low-carbon alloy steel, and the method can be formed by powder metallurgy. The material and the preparation method are not limited thereto. For example, a material similar to the bushing 313 may be used, or the bushing 313 of a suitable size may be directly used. replace. The collar 422 has two end faces 420 spaced apart and respectively corresponding to the sides 428, each of which faces flush with the side 428 of the sheet body 421 on the same plane. In manufacturing, the sheet body 421 and the collars 422 are each formed into a shape, and then the collars 422 are tightly inserted into the sheet body 421.

每一支連接軸43具有一個中軸部431、一個形成於該中軸部431之一端且直徑大於該中軸部431的端擴部432、一個形成於該中軸部431之另一端且直徑小於該中軸部431的頸縮部433,及一個形成於該頸縮部433遠離該中軸部431之一端且直徑大於該頸縮部433的凸頭部434。該中軸部431對應穿伸於該連接片41相對應之套孔411、各別鏈端單元31之軸孔311,及各別套環422之穿孔429。該中軸部431的直徑大於等於該套孔411的孔徑,而小於該軸孔311的孔徑,也小於該穿孔429的孔徑,所以該中軸部431是緊配合地穿設於該套孔411,且鬆配合地穿設於該軸孔311及該穿孔429。該端擴部432靠置於該連接片41遠離該接頭片42之一側。該扣接片44扣接於該等連接軸43之該等頸縮部433且靠置於該等凸頭部434。Each of the connecting shafts 43 has a central shaft portion 431, an end expanded portion 432 formed at one end of the central shaft portion 431 and having a larger diameter than the central shaft portion 431, and one end formed at the other end of the central shaft portion 431 and having a smaller diameter than the central shaft portion The neck portion 433 of the 431, and a convex portion 434 formed at a side of the neck portion 433 away from the one end of the center shaft portion 431 and having a larger diameter than the neck portion 433. The central shaft portion 431 extends through the corresponding hole 411 of the connecting piece 41, the shaft hole 311 of each chain end unit 31, and the through hole 429 of each collar 422. The diameter of the central shaft portion 431 is greater than or equal to the aperture of the sleeve hole 411, and the aperture of the shaft hole 311 is smaller than the aperture of the through hole 429. Therefore, the central shaft portion 431 is tightly fitted to the sleeve hole 411, and The shaft hole 311 and the through hole 429 are loosely disposed. The end expansion portion 432 abuts against one side of the connecting piece 41 away from the tab 42. The fastening tabs 44 are fastened to the constricted portions 433 of the connecting shafts 43 and are placed on the convex heads 434.

參閱圖7,本新型鏈條之一第二實施例的構造大致與該第一實施例相同,其差別在於本第二實施例之該接頭片42的形狀不同,該接頭片42之該連接部424的該等連接緣427平行間隔,該等連接緣427之間的距離由兩側至中央皆相等,而且每一個連接緣427是直線延伸地連接該等環端緣426相鄰之一端。Referring to FIG. 7, the second embodiment of the present invention has a configuration substantially the same as that of the first embodiment, except that the shape of the tab 42 of the second embodiment is different, and the connecting portion 424 of the tab 42 is different. The connecting edges 427 are spaced apart in parallel. The distance between the connecting edges 427 is equal from the two sides to the center, and each connecting edge 427 is linearly connected to one end adjacent to the ring end edge 426.

綜上所述,本新型之該接頭片42主要是在該片本體421內鑲入該等套環422,藉以替換圖1之接頭片22原本圈圍界限出該等穿孔221的部位,使得本新型之每一支連接軸43是插伸於各別套環422所界定的穿孔429中,由於各別套環422具有高硬度及耐磨損等特性,因此使用時不易磨損,可提升該接頭片42之結構強度,避免產生鬆脫或斷裂之問題,能有效提高該鏈條之耐磨損能力,所以可在不影響與該等鏈端單元31間之樞轉作動的情況下,相對降低該鏈條於高速運轉與高拉力運轉時的磨損,進而可延長該鏈條之使用壽命,降低更換該鏈條之頻率,故確實能達成本新型之目的。In summary, the tab 42 of the present invention is mainly such that the collar 422 is embedded in the main body 421 of the sheet body, thereby replacing the portion of the tab 22 of FIG. Each of the new connecting shafts 43 is inserted into the perforations 429 defined by the respective collars 422. Since the respective collars 422 have high hardness and wear resistance, they are not easily worn during use, and the joints can be lifted. The structural strength of the sheet 42 avoids the problem of looseness or breakage, and can effectively improve the wear resistance of the chain, so the relative movement can be relatively reduced without affecting the pivoting operation with the chain end units 31. The wear of the chain during high-speed operation and high-tension operation can prolong the service life of the chain and reduce the frequency of replacing the chain, so the purpose of the present invention can be achieved.

惟以上所述者,僅為本新型之實施例而已,當不能以此限定本新型實施之範圍,凡是依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本新型專利涵蓋之範圍內。However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
