Until the specified rotation speed is reached and the necessary lubricant is supplied to the bearing chamber, the bearing is in dry operation, so with conventional bearings, it was necessary to install a separate water injection position. In reality, liquids containing alumina solids cause significant wear on the bearing surface, necessitating replacement within a short period of time.

易に適用できる。In addition, in the 111 case where ICi containing hard alumina solids such as river sand is handled, even if these solids enter the bearing and get caught in the sliding surface, the solids will be removed from each ceramic piece 3 material. Since the elastic filler 4 that is filled between the shaft sleeve and the shaft sleeve to form a gap therebetween is captured by the elastic filler 4, there is no effect on the sliding surface of the bearing. therefore,
Abrasion resistance ((1,%) Also, ceramic materials become insulating due to electrolytic corrosion, so they are corrosion resistant and have a durability of 1 min against slurry; fσ water. In addition, each ceramic piece is supported and backed up by an elastic material with vibration absorption properties, which compensates well for the properties of ceramics, which are hard but lack some brittleness, resulting in excellent bearing properties. Not only is it easy to assemble, it is also easy to assemble, and because it is divided into segments, it can also be easily applied to doll bearings.

In this embodiment, the housing 1 made of gold J,i'+ (material) has a plurality of grooves 10 with a U-shaped cross section that are open toward the inside and are spaced at equal intervals!gM2. A ceramic piece 3 is fitted into the groove IO through an adhesive elastic body 11 such as hard rubber or Teflon having a thickness of 1 to 2+11111, for example, by (Ja) fitting, and the inner end of the ceramic piece 3 is inserted into the housing 1. The bearing housing 1 slightly protrudes from the inner circumferential surface of the bearing housing 1, and its end surface is formed into a curved surface 3' for making line contact with the shaft sleeve. Similarly, both end plates 6,

明した。(1) Conventional rubber bearings and carbon bearings that use JIS standard 5US316 stainless steel for the shaft sleeve:
199 mm is large in an environment where hard solids are mixed in, making dry operation impossible with rubber bearings, and even carbon bearings have corrosion resistance in 11σ water, a property that accelerates corrosion of other materials in contact due to electrical conduction. There is also a problem. (11) When both the bearing and the shaft sleeve are made of ceramic materials, dry operation is difficult.
Although it is sufficient in terms of monolithicity, it is not reliable when mixed with slurry, especially when large hard fixings are mixed in, as the ceramic is brittle and will be damaged and chipped. Also, care must be taken when installing it as a shaft sleeve. (i
ji) When using carbide materials for both the bearing and the ΦIII sleeve, there is a problem in terms of corrosion in seawater. Furthermore, such bearings made of hard materials are very difficult to assemble into a pump, and if uneven contact occurs, the assembly may become impossible. (1ν) Furthermore, in the product developed earlier by the present inventors, in which the bearing side is made of ceramic and the shaft sleeve is made of carbon copper alloy (Japanese Patent Application No. 57-115674), the ceramic side (bearing side) is made of ceramic and the shaft sleeve is made of carbon copper alloy. (粍 Yi 1: Rich in non-X
+1 (Although it has a good shape, the carbon silk alloy (IIllll bearing sleeve side) will wear heavily in river water mixed with large hard substances such as river sand, and its durability as a bearing will be poor. There was found.

The bearing of the present invention, which uses carbide materials (5% Il'C + 5% Co), has excellent corrosion resistance because one side is made of ceramic for electrical insulation, and also has a 1H dynamic surface! Since the T is the same and the segment 1 is used as a hard material, even if it hits unevenly during assembly, there will be relief in this part, so like the ceramics of the conventional products or the carbide materials, It has the feature that there is no jamming phenomenon and it is easy to handle and assemble. -1 The bearing characteristics listed in Table 1 are as follows.
