分対処できない。 Figure 1 shows the piston of a conventionally used reciprocating internal combustion engine and its surroundings.
1 represents a cylinder liner, 02 represents a piston, and 03 represents a first stage piston ring. FIG. 2 shows an example of a wear curve a along the axial direction of a conventional cylinder liner 01. As shown in Fig. 2, the maximum wear of the cylinder liner 01 generally occurs near the top dead center, where the temperature is high and the back pressure of the first stage piston ring 03 is large. The replacement life of 01 is determined.
Therefore, it has the following drawbacks. (1) The conventional cylinder liner 01 has large uneven wear in the axial direction, so it must be replaced in a short period of time. (2) In addition, as internal combustion engines in particular tend to have higher temperatures and higher pressures, the increase in maximum wear will become more of a problem in the future, as shown in Figure 2, and the conventional cylinder liner 01 cannot adequately cope with this problem.

るものである。 The present invention is characterized in that a cylindrical or conical ring made of ceramic material is divided into a plurality of arbitrary shapes in the axial direction, and the divided rings are fixed inside the upper end of the cylinder liner. Regarding the cylinder liner, in order to reduce uneven wear along the axial direction of the cylinder liner, ceramic materials (including thermal sprayed materials) with high wear resistance under high temperature conditions are used inside the upper end of the cylinder liner. In addition, in the case of cylindrical cylinders made using the above-mentioned ceramic materials, tensile stress is generated inside the cylinder under high pressure conditions, causing damage. The present invention aims to provide an assembled cylinder liner that can be applied to cylinder liners for reciprocating internal combustion engines, cylinder liners for reciprocating compressors used under high temperature and high pressure conditions, and cylinder liners for Stirling engines.

の分割リングの外観を示す。 An embodiment of the cylinder liner of the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 is an explanatory view of one embodiment of the cylinder liner of the present invention, and FIG. 4 is an external view of its arc-shaped split ring. 1 is a conventional cylinder liner with the upper inner side cut 7, 4
is an arc-shaped divided ring made of ceramic material, which is made of a cylinder and divided into a plurality of parts in the axial direction, and the divisions may be curved rather than straight in the axial direction. Ceramic materials are, for example, made of zirconium oxide, zirconium silicate, aluminum oxide, chromium oxide, silicon nitride, silicon carbide, etc., or by thermal spraying.
5 indicates a holding plate, and 6 indicates a bolt. FIG. 4 shows the appearance of the arc-shaped split ring.

く、又摩耗値を下げることができる。 The operation of the present invention will be explained. The arc-shaped split ring 4 is held down by a tightening bolt 6 using a holding plate 5 inside the cylinder liner 1 whose upper part has been cut. In addition to the presser plate 5 and the bolts 6, the split ring 4 may be bonded to the back surface with a high-temperature adhesive. As in the present invention, since the arc-shaped split ring 4 made of highly wear-resistant ceramic material is provided inside the upper end of the cylinder liner 1, which is subject to a lot of wear, uneven wear in the cylinder liner axial direction is less likely to occur. Also, the wear value can be lowered.

するものである。 The present invention has the above-mentioned structure. If a cylindrical ceramic material is used, under high temperature and high pressure conditions, tensile force is generated within the cylinder due to internal pressure, causing cracks and associated damage. However, in the present invention, the ceramic material is Since the cylinder liner is divided into parts and used, it is only subjected to compression, and therefore it has the effect of eliminating problems such as cracks and damage to the cylinder liner.
