関するものでろる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a floating seal installed in the undercarriage of a construction machine.
従来、この種のシールリングは土砂等に対する耐摩耗性
・耐蝕性が侠求されているため、 Ｃ’ｒ・Ａｉｏ−Ｗ
等を含有させた高硬度化材料により製作されているが、
耐摩耗性が不十分である。Conventionally, this type of seal ring has been required to have wear resistance and corrosion resistance against earth and sand, so C'r・Aio-W
It is manufactured using highly hardened materials containing
Insufficient wear resistance.
そこで、本出願人は先に鋼材等の素材によりシールリン

。The seal link manufactured by this method has excellent wear resistance, but on the other hand, it uses expensive Cr-No-11 blue powder, so it has the disadvantage of increasing manufacturing cost.
本発明は上記の事情ｖｃ＠みなされたものであり、その
目的は、優れた耐摩耗性を有すると共に、製造コストを
低減できるようにしたフローティングシールのシールリ
ング製造方法を提供することである。The present invention has been made in view of the above circumstances, and its purpose is to provide a method for manufacturing a seal ring for a floating seal that has excellent wear resistance and can reduce manufacturing costs.

ラップ加工を施すことで、シールリングとする。This seal ring body is subjected to high carbon carburizing treatment in a vacuum carburizing furnace that generates few oxides, and fine carbides, such as carbides (Fe-Cr-C) are formed on the first surface (sealing surface).
It is said to be hard in the system) (1:'r7C
After precipitating carbides such as s, a seal ring is obtained by lapping in the direction of the seal (sliding direction).
この様に製造したシールリングは耐摩耗性が優れている
と共に、ｊＪＡ造コストを安くできる。The seal ring manufactured in this manner has excellent wear resistance and can be manufactured at low cost.

A seal ring manufactured by the method of the present invention, a seal ring manufactured by the conventional bath bombardment method,
When the durability of a sole ring manufactured using a conventional hardness reducing material was tested, the results shown in the surface layer of FIG. 4 were obtained.
