Description

M423175 V. New description: [New technical field] [0001] This creation is a reinforced structure of a chain component, especially a reinforced structure that can produce high hardness, wear resistance and corrosion resistance on the surface of the chain assembly. . [Prior Art] [0002] The chain assembly (chain roller, bushing, inner chain and outer chain) will wear during the operation, and the outer dimensions of the chain assembly will be changed, so that the precision of the chain is lowered, and the driving time is affected. The transmission of power, and the smoothness of the shifting speed, etc., the speed of the shifting bicycle is getting more and more, so that the size requirements of the chain assembly are getting higher and higher. Therefore, the chain can be used for a long time and is precise. The degree will not drop too fast, and it is bound to increase the hardness, wear resistance and corrosion resistance of the chain components. [New Content] [0003] At this point, the creator insists on the long-term use of the chain.

In view of research, a reinforced structure has been developed which is suitable for use in a chain assembly to provide the chain with high hardness, wear resistance and corrosion resistance for the purpose of extending the life of the chain. [0004] To achieve the above functions, a reinforced structure of a chain assembly includes a chromized layer adjacent to the surface of the chain assembly, and a chrome layer attached to the surface of the chain assembly. [0005] Further, the reinforcing structure of the chain assembly comprises a titanium metal layer, and the metal layer is connected to the layer, and the thickness is between 1 #m and 5 /z m. Form No. A0101 Page 3 of 8 M423175 [0006] The thickness of the chrome layer is between 6#111 and 30#^. [0007] The chain assembly includes a chain roller, a bushing, an inner chain piece and an outer chain piece. [0008] The effect of the creation: [0009] 1. Increasing the hardness, the wear and the resistance of the chain assembly. [0010] 2. Extend the life of the chain assembly. [0011] 3 'Improve the bonding strength of the titanium metal layer to the chain assembly. [Embodiment] [0012] The technical features and enhancements of the present invention can be clearly presented in conjunction with the preferred embodiments of the following drawings. First, please refer to the preferred embodiment of the present invention as shown in the figure. A reinforced structure of a chain assembly, the key bar assembly (1) comprising a chain roller, a bushing, an inner chain piece and an outer chain piece, the reinforcing structure comprising: [0013] a chromizing layer (11), The infiltration mode is close to the surface of the chain assembly (1). [0014] a chrome layer (12) is attached to the surface of the chain assembly (1) by infiltration, and has a thickness of between 6//111 and 3 turns to 111 and a hardness of about 15 〇〇hv. The surface of the chain assembly (1) is made to have high hardness, wear resistance and good corrosion resistance. [0015] Please refer to the second figure, 'the preferred method is that the surface of the chain assembly The step-by-step includes a metal layer (13), and the metal layer U3 is coated on the road layer (10) in a twisted manner. The hardness of the metal layer (13) is about 2400 HV, and the thickness is about Between _ and 5 (four), the form number A0101, page 4/eighth page [0016] [0019] [0020], to strengthen the surface of the chain assembly (1) hardness, wear resistance And the corrosion resistance, etc., in addition, the hardness of the chromium layer (12) combined with the titanium metal layer (13) is smaller than the hardness of the titanium metal layer (13), thereby reducing the chain assembly (1) In the process of cracking due to pulling during the operation, in addition to improving the hardness, wear resistance and corrosion resistance of the chain assembly (1), the extension chain can be effectively realized. The purpose of (1) the life of the components. The surface of the chain assembly (1) has a reinforced structure to enhance the life of the chain assembly (1) to provide a chain of better mechanical properties for the user to use. However, the above description is only a preferred embodiment of the present invention. When it is not possible to limit the scope of the creation of the present invention, that is, the simple equivalent change and modification according to the scope of the patent application and the new description of the creation are all creations. Within the scope of the patent. BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a schematic view showing the reinforced structure of the chain assembly of the preferred embodiment (1). The second drawing is a schematic view showing the reinforcing structure of the chain assembly of the preferred embodiment (2).
