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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a lubricating arrangement of a chain assemblage, in particular to one applied to coat the chain components of the chain assemblage with layers of non-electrolytic nickel and Polytetrafluoroethylene alloy to attain effects of automatically lubricating and increasing the surface hardness and durability of the chain without burdening the tensile strength.[0003]2. Description of the Related Art[0004]Generally, the assemblage of the chain is required to be immersed in a heat and liquefied lubricating liquid. When the liquefied lubricating liquid gradually becomes thick lubricant oil at room temperature, the chain assemblage is homogenized to be coated with the lubricant oil. In the long term, the critical occurrence attendant on the lubricant-coated chain is the large consumption of the lubricant oil caused by the wrapping of soil, mud, or sand on the chain components and the combination ther...

AI Technical Summary

Benefits of technology

[0006]The object of the present invention is to provide a lubricating arrangement that coats every chain component with layers of non-electrolytic nickel and Polytetrafluoroethylene alloy to obtain an automatic lubrication and to increase the surface hardness and durability of the chain without burdening the tensile strength.

[0014]1. In view of the first non-electrolytic nickel layer possessing the properties of an even coating, a great adhesion, a high hardness, favorable wear and corrosion resistances, and available welding and coating hardness higher than 500 HV (HRC50). The coating hardness would preferably obtain 1000 HV (HRC70) via processing a specific treatment, so as to efficiently enhance the hardness of the chain assemblage.

[0018](3) a great corrosion resistance to attain a strong chemical stability;

Problems solved by technology

In the long term, the critical occurrence attendant on the lubricant-coated chain is the large consumption of the lubricant oil caused by the wrapping of soil, mud, or sand on the chain components and the combination thereof with the redundant oil.

Such difficulty not only decreases the efficiency of the chain operation but obstructs the further addition of the liquid lubricant into the chain shaft.

The conventional chain also facilely incurs the problems of the rusty chain shaft and the oil stains on user's clothes while operating the chain.

M275160, shown in FIG. 8, also exists the aforementioned deficiencies, in which mainly discloses to embed inner protrusions A1 of chain plates A into respective chain hubs B. Such configuration also renders the lubricating oil unable to drip into chain axles C, and the chain axles C would facilely become rusty and result in the premature abrasion and exhaustion of the chain plates A.
