ものではない。New ceramic materials that have become available with recent advances in fine ceramics technology have the characteristics of traditional ceramics, such as heat resistance and chemical resistance.
Taking advantage of its wear resistance and low coefficient of friction, it is used for things such as skid rails in heating furnaces. On the other hand, as various industrial and consumer machines become smaller and more sophisticated, the bearings that support rotating shafts are required to be smaller and lighter, and to withstand high loads and high rotations. Efforts are being made to meet this demand through improvements in special steel used as bearing materials and advances in processing technology, but the results are still not fully satisfactory.

として有用である。An object of the present invention is to take the current state of the art as described above one step further and provide a bearing made of ceramics that has better performance than conventional steel bearings. [Means for solving the problem] A first aspect of the ceramic double-row ball bearing of the present invention is a double-row ball bearing as shown in FIG. It is an inward angular contact type ball bearing, and the inner ring 2 is a double-row inner ring. Originally, three rows of shoulders are formed for two rows of raceway grooves. It is a raceway ring with a T-shaped cross section.
The outer ring 4 is a double-row outer ring, but in the present invention, it is a composite ring that combines two raceway single rings 4A and 4B, and each raceway single ring has two rows of shoulders forming one row of raceway grooves. It has a cross-sectional shape in which the shoulder portions 41A and 41B on the abutting side are excluded and the other shoulder portions 41A and 41B are left, and these are combined to form a cross-section C.
Shape of the bearing ring. The inner ring 2, outer ring 4, and balls 3 are all made of ceramics. The outer ring 4 must be formed by arranging the balls 3 on the raceway of the inner ring 2 and then combining and integrating the two raceway ring halves 4A and 4B. This can be done in several ways, as explained below. In any case, the distance between the inner and outer raceways should be finely adjusted by adjusting the relative spacing between the two raceway rings, and the bearing should be placed in the optimal position. First, as shown in FIG. 2, the end faces of two raceway ring rings 4A and 4B are butted against each other and bonded together with adhesive 5. In this case, the above-mentioned distance between the tracks is adjusted by adjusting the amount of adhesive and appropriately selecting the spacing between the track rings. Second, as shown in FIG. 3, a male thread 6 is cut in one of the raceway rings, for example 4B, and a corresponding female thread 7 is cut in the other raceway 4Δ, and the two are screwed together. In this embodiment, by appropriately selecting the degree of engagement of the screws, the distance between the tracks can be easily adjusted over a wide range. The third one, as shown in Fig. 4, is a raceway single ring 4A. Cut a male thread 6 on the outer periphery of 4B, and a corresponding female thread 7
Using a cut metal band 8, the two raceway ring rings 4 are integrated by screw connection. The same effect as the second one can be obtained even more easily. Fourth, as shown in Fig. 5, two raceway single wheels 4A,
4B and fit the metal band 9 around the outer periphery.
It is integrated by bending both edges of the metal band. If adjusting the distance between tracks is not particularly important,
Recommended as a simple configuration. As an example of the third modification mentioned above, as shown in Fig. 6,
A female-threaded ceramic outer cylinder 8' can also be used in place of the metal band. It is particularly suitable for applications where the heat resistance of ceramics is desired to be utilized. A second aspect of the ceramic double-row ball bearing of the present invention is a double-row outward angular contact type ball bearing, as shown in FIG. It is a composite ring that combines rings 2A and 2B, and each raceway single ring forms one row of raceway grooves. 2
The other shoulder portion 21A of the row shoulder portions except for the shoulder portion on the abutting side. It is of a cross-sectional type with 21B remaining, and these are combined to form a raceway ring with a C-shaped cross section. In addition, the outer ring 4 is a double-row outer ring and originally forms three rows of shoulders for the two rows of raceway grooves, but the cross section T is obtained by leaving the central shoulder 42 and excluding the shoulders on both sides. It is a shaped bearing ring. In this case as well, the inner ring 2, outer ring 4 and balls 3 are
Both are ceramics. As in the first embodiment, after the balls 3 are arranged on the raceway of the outer ring, the two raceway ring halves 21 must be combined and integrated to form the inner ring. Explaining the means of connection according to the drawings, one of them is similar to the one seen earlier in FIG.
The end faces of the two are butted together and bonded together with an adhesive 5, as shown in FIG. Another type uses the same method as shown in Fig. 4 earlier, and as shown in Fig. 9, a male thread is cut on the outer periphery of the metal coupling ring 10, which has an inner diameter larger than the bearing inner diameter, and two Female threads corresponding to the raceway single rings 2A and 2B are cut, and the inner ring 2 is formed by integrating them by female thread connection. It will be understood from the above explanation that this type allows the distance between the tracks to be easily adjusted. Many other embodiments are possible for the ceramic bearing of the present invention. Depending on the design, the gap between the outer ring and the inner ring can be made wide to some extent, or narrow enough to be substantially sealed, and can be selected as appropriate depending on the application of the bearing. Suitable ceramic materials include alumina, zirconia, silicon nitride, and other fine ceramics, and may be selected depending on the intended use of the bearing product. Each part is manufactured by adding an appropriate binder to fine ceramic powder, press-molding the resulting green (intermediate product), machining the resulting green (intermediate product), cutting threads, and sintering. An appropriate adhesive may be used as necessary to fix the screwed parts, bands, and coupling rings to the outer ring or inner ring. [Function] Conventional steel bearings were assembled by shrink fitting, taking advantage of the metal's large coefficient of thermal expansion. Ceramic materials cannot be assembled using conventional methods because metals do not have significant thermal expansion and the amount of elastic deformation is small. The inventors discovered that ceramic material powder molded using a suitable binder can be precisely machined, and that the machining results in sintering with a nearly constant degree of compaction, resulting in high precision even after sintering. was found to be maintained. Utilizing this, for example, we have established a technology that provides fine-pitch male and female threads to the green and allows them to mesh perfectly, just like when threads are cut into a sintered wheat or metal material. . In the present invention, with the help of such technology, the balls are arranged on the orbit of the inner ring or outer ring of the bearing, and the outer ring and the inner ring in the form of a composite ring are connected by respective means, so that the inner ring, the outer ring, and the ball are connected. They succeeded in constructing a bearing whose main parts are made of ceramics. In the ceramic double-row ball bearing of the present invention, both the inner and outer rings avoid shapes such as undercuts that would be complicated in the production of greens. The need for processing can be eliminated or reduced. The rationalization of the coupling means also facilitates assembly. The ceramic bearing of the present invention can enjoy all the advantages of bearings made of ceramic materials. In other words, it has significantly higher durability than conventional m-made bearings. Therefore, equipment that requires continuous operation for a long period of time,
Suitable for applications where maintenance is difficult.
Ceramics' unique properties such as chemical resistance, acid resistance, and salt water resistance make them useful for various chemical plants and ships. It goes without saying that it is also heat resistant, so
It is useful as a bearing used at temperatures where lubricating oil cannot be used, or at even higher temperatures.
