【発明の詳細な説明】
この発明は少なくとも圧接係止面に耐摩耗性のめっきが
施された組合せオイルリングの改良に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a combination oil ring in which at least the pressure contact surface is plated for wear resistance.
周知のようにエンジンシリンダ内を往復動するピストン
には圧力リングのほかにオイルリングが嵌装され、シリ
ンダ壁面から油を播き落として、燃焼するのを防止する
ようにしている。As is well known, in addition to a pressure ring, an oil ring is fitted to a piston that reciprocates within an engine cylinder, and this is used to spray oil from the cylinder wall and prevent it from burning.

面５に当接して摺動することになる。Usually, an oil ring is fitted into a ring groove of a piston with two sight rails 1 sandwiching a spacer expander 2 between them, as shown in Figs. While being pressed, the inner circumferential surface 3 engages with the ears 4 of the spacer expander and is pushed outward, and the outer circumferential surface of the sight rail comes into contact with the inner surface 5 of the cylinder and slides.

し合い、摩耗する。In this way, the inner circumferential surface 3 of the sight rail and the ears 4 of the spacer expander 2 are strongly pressed together, so as the piston repeats reciprocating motion, the inner circumferential surface 3 of the sight rail and the ears of the spacer expander 2 While in pressure contact with the portion 4, they rub against each other and wear out.

。The inventor first applied particles with an average particle size of 0 to the sliding surface of a wear-resistant sliding part.
This paper presents wear-resistant sliding parts that are coated with phosphorous-containing nickel plating in which 5-5 μm silicon nitride particles are dispersed in 5-30% by volume, hardened by hardening heat treatment to have a micro-Vickers hardness of 800 or more, and are used as pressure rings or oil-resistant sliding parts. It has been stated that a bench test was carried out using a ring which had been subjected to the surface treatment and was fitted into a piston, and the result showed that the ring had excellent wear resistance.

組合せオイルリングに係る。The present invention aims to reduce the wear of the abutting part between the inner circumferential surface of the sight rail and the ear part of the spacer expander in a combination oil ring. In a combination oil ring consisting of a sight rail and a spacer expander, one of the inner peripheral surface of the sight rail and the locking surface of the ear of the spacer expander, which are in pressure contact with each other, is plated with phosphorous nickel. A nickel plating layer containing 2 to 10% by weight of phosphorus is formed on the other layer, and the nickel plating layer holds 5 to 30% by volume of silicon nitride particles having an average particle size of 0.5 to 5 μm dispersed therein. The present invention relates to a famous combination oil ring characterized in that it has been subjected to hardening heat treatment and has a micro Vickers hardness of 800 or more.
本発明に係る窒化珪素分散含燐ニッケルめっきを施すの
には窒化珪素粒子を懸濁させたニッケル・次亜燐酸塩浴

を添加した液をめっき液とし、めっきすべき部品を陰極
とし、ニッケル板またはボールを陽極として電気めっき
を施す方法のいずれでもよい。The silicon nitride dispersed phosphorus-containing nickel plating according to the present invention can be applied by a so-called electroless method in which chemical plating is performed in a nickel/hypophosphite bath in which silicon nitride particles are suspended, or by a so-called electroless method in which silicon nitride particles are suspended. Any method may be used in which electroplating is performed using a standard nickel plating solution with hypophosphite added as the plating solution, the part to be plated as the cathode, and a nickel plate or ball as the anode.
窒化珪素分散ニッケルめっきを施すにあたり、無電解ニ
ッケルめっきの場合にはめっき層の密着性が良好なので
ニッケルストライクめっきは不要であるが、電気めっき
の場合には予めニッケルストライクめっきを施しておく
ことは母材との密着性を良好にするために好ましい。When performing silicon nitride dispersed nickel plating, in the case of electroless nickel plating, the adhesion of the plating layer is good, so nickel strike plating is not necessary, but in the case of electroplating, it is recommended to apply nickel strike plating in advance. This is preferable in order to improve adhesion to the base material.
含燐ニッケルめっき層は熱処理を施すことによって硬さ

発明ではこのような熱処理を施し、めっき層を硬化させ
ておいて使用する。It is known that the hardness of a phosphorous-containing nickel plating layer increases by heat treatment, for example, at 400°C xi.
By the heat treatment of hr heating, the Vickers hardness of about Hv500 is hardened to about HV i o o o. In the present invention, such heat treatment is performed to harden the plating layer before use.
本発明において含燐ニッケルめっきに使用する窒化珪素
粒子の平均粒径は０．５〜５μｍで、最大粒子径が１０
μｍ以下のものが適当であり、これが０．５μｍ以下で
は耐摩耗性改善の効果が不充分であり、また５μｍより
も粗くなるとめつき眉が脆くなり、摺動中に欠は落ちる
ようになり易い。In the present invention, the average particle size of the silicon nitride particles used for phosphorous-containing nickel plating is 0.5 to 5 μm, and the maximum particle size is 10 μm.
If it is less than 0.5 μm, the effect of improving abrasion resistance will be insufficient, and if it is rougher than 5 μm, the fitting will become brittle, and chips will fall off during sliding. easy.
めっき層中の窒化珪素粒子の量は５〜３０容量％が適当
であり、これが５％よりも少ないと耐摩耗性改善の効果
が不充分であり、３０％を越えると摺動相手材を摩耗さ
せることが多くなる上に、含燐ニッケルめっき層の強度
も低下するようになるので好ましくない。The appropriate amount of silicon nitride particles in the plating layer is 5 to 30% by volume; if it is less than 5%, the effect of improving wear resistance will be insufficient, and if it exceeds 30%, it will wear out the sliding mating material. This is not preferable because it increases the number of times the phosphorus-containing nickel plating layer is used and also reduces the strength of the phosphorous-containing nickel plating layer.

The spacer expander was plated with conventional chrome, and the sight rail was coated with silicon nitride dispersed phosphorous nickel plating according to the present invention, and these were fitted onto the piston, and installed into the cast iron cylinder for 700 hours. I did a bench test. For comparison, 2 idle rails and Tough 1 with customary chrome plating are used.

N@φ, 4-cycle, in-line 4-cylinder water-cooled, Fuel: High lead gasoline, The test results are as shown in Figure 4, and the amount of wear on the inner peripheral surface of the sight rail is as shown in Figure 3. If the site rail width is TO, and the width after the test of the part where the spacer expander ear abuts is Ta, then the difference To - Ta (
μm) is expressed as the amount of penetration, and the average value of the upper and lower sight rails is shown. When combined with a chrome-plated spacer expander, the amount of penetration of the inner circumferential surface of the nickel-plated sight rail according to the present invention is approximately 1/4 of the amount of penetration of the inner circumference of the chrome-plated sight rail of the contrast material, and the amount of penetration of the inner circumference of the nickel-plated sight rail according to the present invention is approximately 1/4 of the amount of penetration of the inner circumferential surface of the chrome-plated sight rail of the contrast material, compared to the Tuftride treated sight rail. It can be seen that the combination according to the present invention has excellent wear resistance, with a ratio of about 1/2.

差Ｂ。In addition, the inner peripheral surface of the sight rail was plated with chrome, and the spacer expander was subjected to the silicon nitride dispersed phosphorus-containing nickel plating according to the present invention, and a bench test was conducted under the same conditions as above to extract the spacer expander. Figure 5 shows the results of examining the amount of wear on the panda's ears. The amount of wear is the difference B, where Bo is the width of the ear before the test and Ba is the width after the test.

After 700 hours have elapsed, the amount of penetration of the spacer expander in the combination according to the present invention is approximately 3 times that of the one treated with Tuftride.
Only 0%.

It can be seen that it exhibits excellent wear resistance.

能が維持されるなど実用上の効果がきわめて大きい。As explained above, in the combination oil ring of the present invention, at least the locking surface of the ear part of the spacer expander, as well as the inner circumferential surface of the ID rail, is plated with chrome on one side and silicon nitride dispersed nickel plated on the other side. Since both treated surfaces are placed in contact with each other and fitted into the ring groove of the piston, wear on the pressure contact surfaces between the two is extremely reduced, and as a result, good oil scraping performance is maintained over a long period of time. The effect is extremely large.
