Lubricating arrangement of chain assemblage

Abstract

The present invention pertains to a lubricating arrangement of a chain assemblage serving to coat chain components. Particularly, the lubricating arrangement includes a first non-electrolytic nickel layer and a second PTFE alloy layer that possess 3 to 35 vol % PTFE, whereby the present invention conduces to attain an automatically lubricating capability, increase the surface hardness of the chain assemblage, and prolong the utilization thereof without affecting the tensile strength.

1 . A lubricating arrangement of a chain assemblage applied to components thereof including:
 a first lubricating layer coating surfaces of said chain components; wherein, said first lubricating layer being fabricated of a non-electrolytic nickel layer in a thickness of 2-5 micrometers (μ); and   a second lubricating layer covering a surface of said first lubricating layer; wherein, said second lubricating layer being made of a Polytetrafluoroethylene alloy (PTFE alloy) layer that contains a thickness ranging between 2-8μ and a volume of PTFE ranging between 3-35 vol %.   
     
     
         2 . The lubricating arrangement of a chain assemblage as claimed in  claim 1 , wherein, said chain assemblage comprises one of a chain hub, a chain axle, an interior chain plate, an exterior chain plate and a bushing or the combination of the above. 
     
     
         3 . The lubricating arrangement of a chain assemblage as claimed in  claim 1 , wherein, said chain assemblage is constituted of the eighth group of periodic element. 
     
     
         4 . The lubricating arrangement of a chain assemblage as claimed in  claim 1 , wherein, said non-electrolytic nickel layer has components in weight ranging among 6-13 wt % phosphorus (P) and 87-94 wt % nickel (Ni). 
     
     
         5 . The lubricating arrangement of a chain assemblage as claimed in  claim 1 , wherein, said PTFE alloy layer includes the 20-35 vol % PTFE and a density ranging between 5.9-6.8 g/cm 3 , equating with 6-12.5 wt %; said PTFE alloy layer further comprises components 7.5-10 wt % phosphorus (P) and 77-86 wt % nickel (Ni) 
     
     
         6 . The lubricating arrangement of a chain assemblage as claimed in  claim 1 , wherein, said second lubricating layer is further overlaid with either a reinforcing layer or painting, and said reinforcing layer is preferably a layer of nitrogen titanium (TiN).
