容易性等を満たすものが選択され使用されている。(Prior Art) Conventionally, the most common bearings have been made of metal materials such as cast iron, cast steel, or stainless steel. The material of the above bearing has the required mechanical strength depending on the part where it is used.
Materials that satisfy chemical stability, high or low temperature stability, thermal conductivity, ease of workability, etc. are selected and used.

In the bearing shown in FIG. 6, a large number of holes are formed in a metal outer cylinder 14, and a synthetic resin 15 such as nylon is cast into the inner surface of the outer cylinder to form a bearing.

題点があった。(Problem B to be solved by the invention) However, all of the above bearings are formed by fixing synthetic resin to a metallic outer cylinder by injection molding, etc., which complicates the manufacturing process. Since the synthetic resin used for the bearing is nylon or the like, there were problems such as poor durability.

が大きすぎると樹脂にクラックが生じたり、割れが発生

が生じ軸受の精度が低下する等の問題点が発生した。Therefore, the present inventor used a recently developed synthetic resin material with excellent heat resistance, wear resistance, and lubricity (thermosetting resin such as a condensed polycyclic aromatic resin called Copna resin and polyimide resin). Therefore, an attempt was made to develop a new synthetic resin bearing, but this resin, which has excellent oil-free lubrication performance, has extremely high lubricity. It is difficult to fix the bearing, and therefore, when attempting to process the inner diameter portion of the bearing, slippage occurs between the chuck and the resin, making it difficult to precisely process the inner diameter portion. Furthermore, since this synthetic resin is a thermosetting resin, it is relatively brittle and has relatively low strength, so if this resin is to be used as a bearing, a reinforcing housing is required. Therefore, in order to assemble the housing and this synthetic resin, when trying to form a bearing by press-fitting a resin with excellent oil-free lubrication performance into the housing, if the press-fitting allowance is too large at the time of normalization, the resin may crack or break. Furthermore, even if no cracking occurs, stress is generated in the synthetic resin bearing, resulting in problems such as a decrease in the precision of the bearing.

This is a bearing manufacturing method in which a bearing material made of a thermosetting resin with an excellent oil-free lubrication performance and an external shape is fitted, and then the bearing part of the bearing material is precisely machined with the reinforced housing fixed.

On the other hand, the outer shape of the resin, which has excellent oil-free lubrication performance, is processed by injection molding or the like so that it approximately matches the hole in the housing. Next, the processed thermosetting resin with excellent oil-free lubrication performance is fitted into the hole of the housing, and then the reinforced housing is fixed with a lathe chuck, etc., and the resin is formed with excellent oil-free lubrication performance. The bearing is manufactured by precision processing the bearing part of the bearing material. Bearings made in this way have extremely high machining accuracy and can be used for long periods of time without lubrication, so they can be used in many bearing parts such as industrial machinery.

ジングと軸受部との固定が確実に行える。In the figure, ■ is a bearing made of a thermosetting resin with excellent oil-free lubrication performance, and the outer circumferential surface of this bearing has an uneven portion that matches the uneven portion formed on the inner circumferential surface of the metal housing 3, which will be described later. 2 is formed. The resins with excellent oil-free lubrication performance include heat-curing condensed polycyclic aromatic resins (called SK Resin L by the trade name) and polyimide resins. It is a curable resin and has extremely high lubricity. 3 is a metal housing;
This housing serves to reinforce the inherent brittle nature of the thermosetting resin used as the bearing, and is made of materials such as iron, aluminum, and other light alloys. On the inner circumferential surface of the housing,
A large number of depressions and depressions 4 are formed. The bearing portion and housing formed as described above are assembled in the following manner. First, the uneven portion formed on the outer periphery of the bearing portion 1 made of synthetic resin is fitted into the uneven portion of the hole of the housing formed as described above (see FIG. 2). Next, the outer periphery of the housing part of the thus assembled members is fixed with a chunk of a lathe or the like, and in this state, the inner surface of the bearing is precisely machined to manufacture the bearing. At this time, since the non-slip housing part is fixed with a chuck, the holding force required when cutting synthetic resin can be easily obtained, and relative rotation between the synthetic resin and the housing is prohibited by the uneven parts. The inner diameter part of the bearing part can be machined with extreme precision. Further, when the fitting portion is formed with a large number of projections and depressions as in this embodiment, the contact surface between the housing and the bearing portion becomes large, and the housing and the bearing portion can be securely fixed.

For example, the outer periphery of the synthetic resin bearing may be It may be made into a polyhedron or an uneven shape such as a triangular mountain or a wave shape.

の形状に制限は無い。The one shown in Fig. 3 is another example in which a synthetic resin bearing part is formed in the same manner as above on a metal housing having a flange 5, and as in this example, the shape of the housing side is There are no particular restrictions. The fourth example shown is another example in which the shape of the bearing portion is modified. In this embodiment, a flange 6 is formed on the bearing part 1 assembled to the housing 3, and the flange 6 restricts movement of the bearing part 1 fitted into the housing 3 in the bearing direction. Therefore, when the flange side of the bearing section is attached to, for example, a wall surface, the flange of the bearing section is sandwiched between the wall surface and the housing, and the bearing section is prevented from coming off from the housing. Note that there is no particular restriction on the shape of this flange as long as it has a shape that can restrict movement in the bearing direction.

Easy to assemble with. Furthermore, since the non-slip housing part is fixed in chunks, it is easy to obtain the holding force required when cutting synthetic resin, and since relative rotation between the synthetic resin and the housing is prohibited by the uneven parts, bearing The inner diameter of the part can be machined with extreme precision. In addition, if the fitting part is formed with many unevenness,
The contact surface between the housing and the bearing section is increased, and the housing and the bearing section can be securely fixed. Furthermore, since the resin is reinforced with the housing, the bearing strength is also improved, which provides excellent effects.
