(産業上の利用分野)
この発明は9例えば摺動軸受の摺動面に用いる摺動材及
びその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sliding material used for the sliding surface of a sliding bearing, for example, and a method for manufacturing the same.
(従来の技術)
従来この種の摺動材としては、樹脂コーティング摺動材
や青銅系の母材中に固体潤滑剤を埋め込んだものが用い
られている。(Prior Art) Conventionally, as this type of sliding material, resin-coated sliding materials or materials in which a solid lubricant is embedded in a bronze-based base material have been used.
そしてこのような摺動材を製造するには通常青銅系の母
材をドリルを用いて穿孔して、これに固体潤滑剤を埋め
込んでいる。In order to manufacture such a sliding material, a hole is usually made in a bronze base material using a drill, and a solid lubricant is embedded in the hole.
(発明が解決しようとする問題点)
上記従来の摺動材では母材が比較的軟らかくて許容面圧
がせいぜい1000kir/cd程度であって。(Problems to be Solved by the Invention) In the above conventional sliding materials, the base material is relatively soft and the allowable surface pressure is about 1000 kir/cd at most.
高面圧に耐えることができないと共に、固体潤滑剤を埋
めこむための穴をドリルを用いて穿孔する関係で、硬い
母材の穿孔は不可能であり。In addition to being unable to withstand high surface pressure, it is impossible to drill holes in hard base materials because the holes for embedding the solid lubricant must be drilled.
また個々に各穴を穿孔しなければならず、甚だ手間がか

を要する。またドリルによる穿孔では細い孔明けも限界
があり、母材表面に開口する穴の周辺(エツジ)にかえ
りが出る等製造上問題があり、コスト高にもなる。Furthermore, each hole must be drilled individually, which is very time consuming and requires a great deal of time to change and adjust the pitch of the holes. In addition, drilling with a drill has a limit to the ability to make small holes, and there are manufacturing problems such as burrs appearing around the holes (edges) formed on the surface of the base material, which also increases costs.
この発明は上記不具合を解消することをその目的とする
。An object of the present invention is to solve the above-mentioned problems.
(問題点を解決するための手段及び作用)この発明は上
記の点に鑑みなされたものであって、鋼板又はセラミッ

動特性のすぐれた摺動材が得られるものである。(Means and effects for solving the problems) The present invention has been made in view of the above points, and consists of drilling small holes in a base material made of a hard material such as a steel plate or ceramic using a laser or an electron beam. A sliding material is formed by impregnating the small holes with a solid lubricant or resin, and the sliding material can sufficiently withstand high surface pressure and have excellent sliding characteristics.

効率よく高品質の摺動材を製造することができる。In addition, the above-mentioned small holes can be drilled quickly and easily at any pitch using a laser or electron beam, and there is no burr around the opening on the base material surface, producing high-quality sliding materials extremely efficiently. can do.
(実施例)
以下にこの発明の実施例を第工図〜第3図を参照して説
明する。(Example) Examples of the present invention will be described below with reference to FIGS.
図において1は母材で鋼板やセラミックス等の硬い材料
を用いる。そして上記母材1に、第1図に示すようにレ

示したようにその***の中に黒鉛1M −S t、
W S x等の固体潤滑剤又はPTFE(ポリエチレン
テレフタレート)、ポリアセタール、ナイロン等の樹脂
を埋め込ませたものである。In the figure, reference numeral 1 denotes the base material, which is made of a hard material such as a steel plate or ceramics. Then, as shown in Fig. 1, a small hole with a diameter of 0.05 to 5 m and a depth of o, i to 2 fi is made in the base material 1 using a laser or an electron beam, as shown in Fig. 2. As shown, graphite 1M-S t is placed in the small hole.
It is filled with a solid lubricant such as W S x or a resin such as PTFE (polyethylene terephthalate), polyacetal, or nylon.

ている。The lubricant embedding method is 1.For example, in the case of PTFE, a roll impregnation method is used, and in the case of solid lubricants such as graphite and MoS*, it is mixed with a thermosetting resin such as phenol and made into a clay-like form. It is impregnated into the hole using the roll impregnation method.

の穴の形状は第3図に拡大して示したように、母材1の
表面に開口する穴の周辺部分2aはRがついてなだらか
となるので、従来のドリルによる穴のように周辺部分に
かえりが出るようなことがない。Furthermore, when a small hole is made using a laser or an electron beam, the shape of the hole is rounded and gentle in the peripheral part 2a of the hole opened on the surface of the base material 1, as shown in an enlarged view in FIG. Therefore, unlike holes made with conventional drills, burrs do not appear in the surrounding areas.
また母材に穿設される穴2の形状は2bに示したような
ギザギザの形状(直線状でない)となり、従ってこの穴
2に埋め込まれる固体潤滑剤や樹脂は、上記ギザギザの

ので、ぬけ出すようなことがなくなる。In addition, the shape of the hole 2 drilled in the base material is a jagged shape (not a straight line) as shown in 2b, so the solid lubricant or resin embedded in this hole 2 does not meet the above-mentioned jagged surface. By making a close contact, it is firmly fixed in the hole, so it will not slip out.

。Furthermore, since a laser or an electron beam is used to make the small holes, the holes can be easily drilled even if the base material is hard, and fine holes can be quickly drilled at any pitch. (For example 100
7 seconds, pitch 1B, 100 X in 100 seconds
Can drill 100 holes. ) The sliding material manufactured in this way has an embedded lubricant that covers the sliding surface during sliding, and exhibits good sliding characteristics even without oil or fat. High strength 2: Since high hardness steel plate, ceramic, and glue are used, this base material supports the mating material, so it can withstand higher surface pressure than conventional products.

Since the sliding material was formed by embedding a solid lubricant in the
Small holes of any pitch can be drilled into a hard base material extremely efficiently and with high precision, and the solid lubricant embedded in the small holes is tightly adhered, so it will not come off during sliding.
A sliding material that can withstand much higher surface pressure than conventional materials can be obtained.
