Description

【発明の詳細な説明】 「産業上の利用分野」 本発明は、バルブリフター、カムフォロアー、ロッカー
アーム、バルブステム等のように摺動面を備えた部品に
好適に利用され得る。DETAILED DESCRIPTION OF THE INVENTION “Industrial Application Field” The present invention can be suitably used for parts having a sliding surface such as a valve lifter, a cam follower, a rocker arm, and a valve stem.

「従来の技術」 機械部品の摺動面は、これと対になる他部品の摺動面と
の片当りを防止するため、中央部を外縁部付近に対して
数μｍ〜数十μｍ高くして緩勾配の山形とする所謂クラ
ウン形状となっていることが必要とされる。"Prior Art" The sliding surface of a mechanical part is set to have a center part higher than the outer edge part by several μm to several tens of μm in order to prevent uneven contact with the sliding surface of other parts paired with it. It is necessary to have a so-called crown shape that forms a gentle slope mountain shape.

一方、近年摺動部の耐摩耗性を向上させる目的で、部品
本体を従来通り金属製とし、摺動部分のみ窒化ケイ素、
炭化ケイ素、サイアロン等の耐摩耗性部材を接合したも
のが実用化されている。On the other hand, in recent years, for the purpose of improving the wear resistance of the sliding portion, the component body is made of metal as usual, and only the sliding portion is made of silicon nitride,
Those in which wear resistant members such as silicon carbide and sialon are joined have been put into practical use.

「発明が解決しようとする問題点」 しかし、クラウン形状を耐摩耗性部材の表面に形成する
方法として、焼結後の耐摩耗性部材を研磨する方法で
は、クラウン形状が三次曲面であることから多大のコス

ウン形状を形成しておき、焼成して焼き放し面のまま用
いる方法では焼成時の変形収縮によって、寸法精度が低
下する。"Problems to be solved by the invention" However, in a method of polishing a wear-resistant member after sintering as a method of forming a crown shape on the surface of the wear-resistant member, the crown shape is a cubic curved surface. It costs a lot of money. On the other hand, in a method in which a ceramic unfired body is preliminarily formed with a crown shape and is fired to be used as it is, the dimensional accuracy is deteriorated due to deformation and shrinkage during firing.

本発明は、かかる問題点を解決し、低コストで寸法精度
良くクラウン形状を形成することを目的とする。An object of the present invention is to solve such a problem and to form a crown shape at low cost with high dimensional accuracy.

「問題点を解決する手段」 その手段は、摺動面に本体よりも熱膨張率の小さい耐摩
耗性部材を加熱接合すると同時に、接合部の冷却収縮に
より該耐摩耗性部材の接合面の反対面をクラウン形状と
するところにある。"Means for solving the problem" The means is to heat-bond a wear-resistant member having a smaller coefficient of thermal expansion than the main body to the sliding surface, and at the same time, the cooling shrinkage of the bonding portion causes the wear-resistant member to oppose the bonding surface. The surface is in the shape of a crown.

「作用」 本発明の作用を第１図の模式図をもって説明する。第１

合される。"Operation" The operation of the present invention will be described with reference to the schematic view of FIG. First
FIG. 1A shows a preparatory state before joining the metal shaft 1 which is the main body and the ceramics which is the wear resistant member, and the brazing material 3 is interposed therebetween. In this way, the metal shaft 1, the brazing material 3 and the ceramics 2 are heated in a state of being in contact with each other, and then cooled, so that the metal shaft 1 and the ceramics 2 are brazed and joined.

この際、セラミックス２の熱膨張率が金属軸１のそれよ

とするのが望ましい。0.05に満たないとセラミックス２
の強度が低下するし、0.3を越えるとセラミックス２が
変形しにくくなるからである。At this time, since the coefficient of thermal expansion of the ceramic 2 is smaller than that of the metal shaft 1, the amount of radial shrinkage of the metal shaft 1 during cooling becomes larger than that of the ceramic 2. Therefore ceramics 2
A compressive stress is applied to the vicinity of the joint surface in the radial direction, and the central portion on the non-joint surface side is deformed so as to bulge and a crown shape is formed as shown in FIG. 1 (B). The size of the crown is
When the sliding parts are chips used for valve lifters and stems of valves, it is appropriate that the crown top height is several μm to several tens of μm for a crown installation width of 10 mm. To add the ratio of the thickness of the ceramics 2 to the maximum width of the joint (maximum diagonal length in the case of polygonal cross section, major axis in the case of elliptical cross section) is 0.05 to 0.3.
Is desirable. Ceramics 2 if less than 0.05
This is because the strength of the ceramics decreases, and when it exceeds 0.3, the ceramics 2 becomes difficult to deform.

なお、この比の上限は、セラミックス２の接合面側の中
央部近傍に第２図（Ａ），（Ｂ）に示すくぼみ2aのよう
に、金属軸１及びロー材３との非接触部分を設けること
により、0.5とすることができる。変形が容易となるか
らである。Note that the upper limit of this ratio is a non-contact portion with the metal shaft 1 and the brazing material 3 in the vicinity of the central portion on the joining surface side of the ceramics 2 as in the recess 2a shown in FIGS. 2 (A) and 2 (B). It can be set to 0.5 by providing it. This is because the deformation becomes easy.

また、セラミックスとしては窒化ケイ素又はサイアロン
を主成分とする焼結体が好ましい。熱膨張率及びヤング
率が小さいため、クラウンがつきやすいからである。Further, as the ceramic, a sintered body containing silicon nitride or sialon as a main component is preferable. This is because the thermal expansion coefficient and Young's modulus are small, so that the crown is easily attached.

A chip made of a silicon nitride sintered body of × 2 tmm, 33 is a layer of a brazing material and a cushioning material. The valve 30 was manufactured by bonding a chip 32, whose non-bonding surface to be a sliding surface was previously polished to a straightness of 2 μm or less and metallized on the bonding surface, to the main body 31 with an Ag low 33. The central portion of the non-bonding surface of the chip 32 had a crown shape which was 4 to 8 μm (n = 20) inflated from the ridgeline surrounding the same surface.

The valve lifter 40 was manufactured by sequentially diffusion-bonding the main body 41, the ring 43, and the sliding portion 42. After joining, the non-joint surface of the sliding portion 42 is 7 to 15 μm (n = 1
It had a crown shape with a height of 0).

「発明の効果」 接合前の耐摩耗性材料を予め平面研摩しておくだけで寸

く平面研摩であるから、コストも低い。"Effects of the Invention" A crown shape with good dimensional accuracy can be obtained simply by preliminarily flat-polishing the wear resistant material before joining. Therefore, the cost is low because the surface polishing is not the curved surface polishing.
