Theoretically, an equal centering torque is applied to the spherical metal 1, but the centering torque of the spherical metal depends on the frictional force between the spherical metal 1 and the holding plate 3, and the elasticity of the holding plate 3 However, since the presser plate 3 is made of a steel plate, the frictional force is large, and it is difficult to keep the alignment torque constant unless the presser plate 3 is formed with extremely high precision. be. Further, there are potential problems such as a concern that a gap may be formed between the presser plate and the spherical metal due to the influence of temperature changes.

has a short cylindrical shape with openings at both ends in the axial direction, and one of the openings is tapered to have an inner diameter smaller than the outer diameter of the spherical metal 12. A holding portion 20 is formed, and a portion of the outer circumference of the spherical metal 12 is brought into contact with the inner peripheral slope of the holding portion 20 to position the spherical metal 12. A presser member 16 that is inserted and positioned from the other opening of the exterior body 17
is made of heat-resistant synthetic resin, such as polyimide resin, and as shown in FIGS. 2 to 4, five holding protrusions 14 extend from a ring-shaped base 10 in the circumferential direction. They are provided at equal intervals and extend in a direction (axial direction) parallel to the axis X of the spherical metal 12, and one anti-rotation protrusion 15 is provided at one interval of the presser protrusion 14. It is protruded and has a circular comb-like shape. The diameter D 1 of the virtual circle C passing through the outer surface 11 of the tip of each presser protrusion 14 and the rotation stopper protrusion 15 is slightly larger than the outer diameter D 2 of the ring-shaped base 10, that is, the inner diameter of the exterior body 17 (described later). It is formed small, thereby allowing elastic deformation of each presser protrusion 14 outward. An inclined surface 13 along the outer circumferential surface of the spherical metal 12 is formed on the inner surface of the tip portion of each presser protrusion 14 . This inclined surface 13 comes into contact with the outer peripheral surface of the spherical metal 12 and holds the spherical metal 12 on the side opposite to the holding portion 20 of the above-mentioned exterior body 17. The outer diameter D 2 of the ring-shaped base 10 of the presser member 16 described above is formed to be substantially equal to the inner diameter of the exterior body 17, and is inserted into the exterior body 17 by applying a pressing force. In the present embodiment, the presser member 16 is fixed as shown in FIG. The holding protrusions 14 are positioned and set in a state in which they are in elastic contact with the outer periphery of the metal 12 and are slightly elastically deformed and expanded outward. Reference numerals 21 and 22 in FIG. 1 are lubricating oil absorbing materials such as felt, and the lubricating oil absorbing material 22 on the holding member 16 side is held between the respective holding protrusions 14 described above.
Therefore, if each presser protrusion 14 is formed so that its side surfaces 14A are parallel, the inner interval of each presser protrusion 14 will be smaller than the outer interval, and the lubricating oil absorbing material 22 will be securely held, which is convenient. be.

奏する。 The rotation preventing protrusion 15 of the holding member 16 is attached to the spherical metal 1
By inserting it into the exterior body 17 and fixing it in a predetermined position while aligning it with the groove of 2, the spherical metal 12 can be accurately held in a self-centering state, and the ease of assembling the bearing can be significantly improved. can. Moreover, since the spherical metal 12 is held by the sufficient elasticity of each presser protrusion 14, the permissible positioning range of the presser member 16 is expanded, the self-aligning torque is stable, and even when temperature changes occur, each Presser protrusion 14
There is no gap between the spherical metal 12 and the spherical metal 12. Furthermore, since the presser member 16 is made of heat-resistant synthetic resin and elastically holds the spherical metal 12 on the inclined surface 13 of each presser protrusion 14, the pressure on the pressurizing surface is lower than that of a conventional metal presser plate. The frictional force is small, smooth rocking of the spherical metal 12 is achieved, constant self-aligning torque is obtained, and wear and tear on the pressurized surfaces is avoided, especially at the portion of the anti-rotation protrusion 15 due to friction. It can prevent the occurrence of wear and tear, and not only withstands long-term use, but also exhibits a vibration-proofing effect. Furthermore, each presser protrusion 14 is provided with a lubricating oil absorbing material 2.
2 can be disposed, and the disposed lubricating oil retaining material 22 can be reliably held between the respective presser protrusions 14, resulting in many practically beneficial effects.
以上詳述したように、本考案によれば、以下に
列挙するような種々のすぐれた効果が得られ、実
用上きわめて有用な自動調心すべり軸受を提供す
ることができる。 As described in detail above, according to the present invention, various excellent effects as listed below can be obtained, and a self-aligning sliding bearing that is extremely useful in practice can be provided.

固定手段を別途施す必要が全くない。(1) The outer diameter of the base of the holding member is approximately the same as the inner diameter of the short cylindrical bearing outer body, and the base is inserted into the bearing outer body while applying a pressing force,
Since the outer periphery of the end face of the base is positioned and fixed by the bent flange formed by bending the opening edge of the bearing exterior body inward, when fixing the presser member, fixing means such as adhesive can be used. There is no need to apply it separately.
したがつて、組立工数が少なくかつ作業も容
易で、軸受内部への潤滑剤の封入も容易に行
え、組立作業性がきわめて良好である。 Therefore, the number of assembly steps is small, the work is easy, and lubricant can be easily filled inside the bearing, resulting in extremely good assembly workability.

て、予圧を与えられることとなる。(2) The holding member is made of heat-resistant synthetic resin, and the diameter of an imaginary plane passing through the outer surface of the tip of each metal holding protrusion of the holding member is set to be slightly smaller than the inner diameter of the bearing exterior body. Because I have
In the bearing assembled state, outward elastic deformation of each of the metal holding protrusions is allowed within a predetermined range, and as a result, the spherical metal is held by the sufficient elasticity of each of the metal holding protrusions. , a preload will be applied.

て、すぐれた防振効果を発揮する。 Therefore, the permissible positioning range of the spherical metal by the presser member has been greatly expanded compared to the conventional method, and as a result, the self-aligning torque is stabilized, and even when temperature changes occur, the positioning range of the spherical metal and each presser protrusion is significantly expanded. Furthermore, it effectively absorbs vibrations from motors, etc., and exhibits excellent vibration-proofing effects.

属製押え板に比べてはるかに小さい。(3) In addition, the holding member is made of heat-resistant synthetic resin, and the inner surface of the tip of each holding protrusion is an inclined surface that follows the outer circumferential surface of the spherical metal, and this inclined surface makes the spherical metal elastic. Because it is held in place, the frictional force (friction coefficient) on the holding surface (pressure surface) of the spherical metal is much smaller than that of conventional metal holding plates.

寿命が長い。 Therefore, smooth rocking of the spherical metal is guaranteed, and stable self-aligning torque can also be obtained in this respect. Further, wear and tear on both of the pressurizing surfaces is also avoided, and in particular, wear and tear due to friction is effectively prevented in the portion of the anti-rotation protrusion, so that the bearing can withstand long-term use and has a long bearing life.
