As shown in FIG. 8, the current-carrying wire 1 is made of a bent wire material, and the arcuate portion of the outer circumference is attached to the outer ring 2, and the bent portion on the inner circumference side is in sliding contact with the inner ring 3. .

By fitting the rubber seal 6 into the annular groove 2a from the outside, the current-carrying wire 1 is prevented from coming off, and

含有成分が揮発しやすいので、真空度を保つ上で好まし
くない。As described above, in the case where the energizing wire 1 is prevented from coming off by the rubber seal 6, the rubber of the rubber seal 6 softens or deteriorates in an environment at a temperature higher than the baking temperature. Therefore, it cannot be used in a high temperature part such as a heat roller of a copying machine. Further, in a vacuum, the rubber-containing component easily volatilizes, which is not preferable for maintaining the degree of vacuum.

けた箇所では、ゴムシール６が押える対象物がないため
に波打って凹凸ができ、密封性が低下する。Moreover, the current-carrying wire 1 is pressed from the outside by the rubber seal 6. However, since the current-carrying wire 1 has a shape in which a part of the current-carrying wire 1 is cut off in the circumferential direction, the rubber seal 6 is not attached at the position where the current-carrying wire 1 is missing. Since there is no object to be pressed, it becomes wavy and uneven, resulting in poor sealing.

がある。On the other hand, a metal shield ring 7 for preventing the current-carrying wire 1 from coming off is not affected by heat due to its material and can be used in a high temperature environment or in a vacuum without any problem. Similar to the rubber seal 6 described above, a gap is created at a portion where the current-carrying wire 1 is chipped, and the sealing performance is similarly deteriorated. Moreover, when the shield ring 7 is deformed under pressure so as to come into close contact with the inner surface of the annular groove 2a, the outer peripheral surface of the outer ring 2 may be distorted by the applied pressure, and the roundness thereof may be impaired.

課題とする。The present invention addresses the above-mentioned conventional problems and allows the current-carrying wire to be attached without impairing the roundness of the bearing ring, and it also causes trouble even in a high temperature environment or in a vacuum. An object of the present invention is to provide an electrically conductive bearing that can be used without any need.

うる環状板である構成とした。According to the present invention, in order to achieve the above object, a snap ring type current-carrying wire is attached to an annular groove formed at an end portion of either one of an outer ring and an inner ring. In the current-carrying bearing that is used, a metal sealing plate that also functions as a retaining member is attached to the outside of the current-carrying wire, and the sealing plate is an annular plate that has a crack in one place and can elastically expand and contract. did.

In this case, the sealing plate can be expanded and contracted in one place, so if you reduce the diameter by pressing it into the annular groove and then release the pressure, it will return to the large diameter and the elastic resilience will restore the annular groove. It is fixed on and prevents the energizing wire from coming off. The restoring force of the sealing plate is applied to the bearing ring, but no excessive force is applied.

縮しうる。A feature of the current-carrying bearing of this embodiment is that a sealing plate 8 made of a metal ring-shaped plate having a slit-like split S in one place is attached to the ring-shaped groove 2a from the outside of the current-carrying wire 1. It is that. The sealing plate 8 also serves as a retaining member for the energizing wire 1, and is a flat annular plate having no irregularities other than the split S. By opening or closing the split S portion, the sealing plate 8 can be moved inward and outward in the radial direction. It can be elastically scaled.

密封板８を嵌めるのであるが、密封板８は拡縮自在であ

After that, the sealing plate 8 is fitted into the annular groove 2a from the outside of the current-carrying wire 1. Since the sealing plate 8 is expandable and contractible, it is fitted into the annular groove 2a with a small diameter.

増すように設計されている。That is, the sealing plate 8 is squeezed to a small diameter by closing the portion of the split S, put in the inside of the annular groove 2a in that state, and then the pressure is released. Then, the sealing plate 8 tries to return to the large diameter and is fixed in the annular groove 2a by its restoring elasticity. As a result, the current-carrying wire 1 is prevented from coming off, and the split S portion of the sealing plate 8 is kept in a substantially closed state, thus sealing the bearing. In this case, since the restoring elasticity of the sealing plate 8 is applied to the outer ring 2 and an excessive external force is not applied, the outer ring 2 is not deformed. Further, the inclined surface of the annular groove 2a acts so that the expanding force of the sealing plate 8 acts inward in the axial direction, and in this respect also, the fixing force of the energizing wire 1 by the sealing plate 8 is designed to increase. Has been done.

なる。In the second embodiment, the two sealing plates 8 are mounted in the annular groove 2a from the outside of the current-carrying wire 1 in a stacked manner as described above. The positions are shifted in the circumferential direction so that they do not overlap. In this way, since the split S of the one sealing plate 8 is shielded by the other sealing plate 8, the sealing performance is higher than that of the first embodiment.

うになっている。In the third embodiment, an unbroken metal shield ring plate 9 is attached to the annular groove 2a from the outside of the current-carrying wire 1, and the sealing plate 8 having the split S as described above is provided on the outside thereof. The shield ring plate 9 and the sealing plate 8 are mounted so as to prevent the conductive wire 1 from coming off and seal the bearing. The shield ring plate 9 is formed with an outer diameter that can be inserted into the outer ring 2 without being caught, and shields almost the entire gap between the outer ring 2 and the inner ring 3.
In this example, the sealing plate 8 has an inner diameter larger than that of the inner ring 3, and mainly prevents the current-carrying wire 1 and the shield ring plate 9 from coming out.
Of the gap between the inner ring 3 and the inner ring 3, a portion near the outer ring 2 is sealed.

May be a slit cut obliquely as shown in FIG. 7, or may be a step-like slit.
In the case of a slit having such a shape, since the split S does not blow straightly in the axial direction, it is not necessary to set the split S in a closed state with the sealing plate 8 mounted in the annular groove 2a. It is advantageous in that the design becomes easy. Further, in each of the above-mentioned embodiments, the annular groove 2 is provided at the end of the outer ring 2.
