サビである。Conventionally, this type of wedge has been shown in Fig. 1. In the figure, (1) is the inner ring of the bore ring, (2)
is the core bolt welded to this inner resig (1), (31 is the outer ring of the bore ring, (4) is the bore ring bolt for tightening this outer ring (3), and (5) is the outer ring (8). It is a triangular wedge that is inserted into the split part.

Insert the wedge (5) into the split part of No. 4, and weld the wedge (5) and the outer ring (3) to secure them. After welding the core bolt (2), insert the wedge (5).
It was designed to remove the .
従来のクサビは以上のように構成されており、クサビを

り、また外リングとの接触が勝当りのため、ボアリング
１ｌｌｉｄｌｉ性が小びく、コアボルト溶接時にボアリ
ング変形にバラツキが多いなどの欠点があった。Conventional wedges are constructed as described above, and since the wedge is fixed by welding, it takes time to install and remove it, and since the contact with the outer ring is perpendicular, the bore ring 1llidliability is small, and the core bolt There were drawbacks such as large variations in bore deformation during welding.
この発明は、上記のような従来のものの欠点を除去する

のバラツキを少なくする串を目的・とじている。This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by using a set of two tapered wedges, it is easy to attach and detach.
The aim is to create a skewer that improves boring rigidity and reduces variation in deformation after welding.
以下この発明の一実施例を図について説明する。An embodiment of the present invention will be described below with reference to the drawings.
即ち第２図において、（１）〜（４）は上記第１図のも

ある。That is, in Fig. 2, (1) to (4) are the same as those in Fig. 1 above, and (6a) and (6b) are a set of two tapers inserted into the split part of the outer ring (3). It is a wedge.
次にその作業方法について説明する。まず従来と同様に

取除くようにしたものである。Next, the working method will be explained. First, as in the conventional case, the bore ring bolt (4) is tightened to apply tightening force to the inner ring (1), and then the outer ring (3) is tightened. H
After tightening the bore ring bolt (4) by the r amount, drive wedges (6a) (6b) into the split portion of the outer ring (3) with a hammer (do not weld). And the core bolt (
After the welding in 2) is completed, the wedges C6a) and (6b) are folded and removed.
