Things can be supplied at low cost. Also, since the eccentric ring 20 to be assembled with the eccentric ring 20 has a cylindrical inner and outer diameter, the inner and outer raceway surfaces 3i and 3o have a conical shape like the intermediate wheel 3 in the conventional triple race eccentric tapered roller bearing (FIGS. 3 and 4). Compared to processing with eccentricity, it is possible to supply an inexpensive and accurate one.

胴９及び圧胴１０と再接触させて次の印刷を行う。Now, this triple race eccentric bearing unit is used as a bearing for supporting the blanket cylinder 8 of the offset printing machine shown in FIG. In the printing process, the blanket cylinder 8 supported by the inner ring 1 rotates at a high speed while being pressed against the plate cylinder 9 and the impression cylinder 10. The ink applied to the plate is transferred to printing paper via the blanket cylinder 8 and printed.
In the subsequent paper discharging step, the release mechanism is operated to discharge the paper on which printing has been completed. In this case, the blanket cylinder 8 is moved by operating the bracket 7 to rotate the intermediate wheel unit 25 half-way, leaving a gap between the cylinders, and allowing the paper to pass. After passing the paper, the bracket 7 is immediately operated in the reverse direction to rotate the intermediate wheel unit 25 in the reverse direction, so that the blanket cylinder 8 comes into contact with the plate cylinder 9 and the impression cylinder 10 again, and the next printing is performed.

良い。The operation of the intermediate wheel unit 25 in this case is as follows.
This is exactly the same as the case of the intermediate wheel 3 in the conventional eccentric bearing, and does not cause any inconvenience in function. Also, in the eccentric bearing unit of the present invention, the preload adjustment of the outer tapered rollers 4 can be easily performed by adjusting the width direction dimension of the outer ring spacer 2K, and the preload adjustment of the inner rolling element row 5 can be easily performed. Can also be easily performed by adjusting the width of the inner ring spacer 1K in the width direction. Alternatively, a structure in which the inner races are directly opposed to each other without interposing the spacer 1K between the inner races 1 and 1 may be used to tighten the inner race 1 with a nut or the like to apply an appropriate preload.

対しても本発明を適用することができる。In the above embodiment, the case where the inner and outer bearings are all tapered roller bearings has been exemplified. However, the present invention is not limited to this, and other bearings such as ball bearings such as angular ball bearings and cylindrical roller bearings may be used. Alternatively, the present invention can be applied to a combination of different bearing types.

軸受ユニットを提供できるという効果を奏する。As described above, according to the first aspect of the present invention, two sets of concentric rolling bearings having a large and small general shape are fitted between the two sets of bearings. Since the eccentric bearing unit is constructed by combining the eccentric rings each having a cylindrical shape with the inner and outer diameter surfaces serving as the intermediate wheel, unlike the conventional eccentric tapered roller bearing, two sets of inner and outer concentric bearings are easily mass-produced in the normal mass production process. It is possible to manufacture the eccentric ring, and it is not necessary to process the bearing raceway surface such as a conical surface by eccentricity. As a result, it is possible to provide an accurate eccentric bearing unit at a lower cost than the conventional one.
