Claims

[Claims for Utility Model Registration] (1) In a positioning structure for a bearing housing of a rotating electric machine or the like having three or more bearings: Adjustment of the bearing housing in a state where a first bearing and a second bearing are connected by a spigot joint. A plurality of screw holes formed in a casing of a rotating device such as a rotating electrical machine and a plurality of bolt holes formed in a housing of a third bearing for positioning;
a positioning member consisting of a plurality of bolts and nuts screwed into the bolt hole; a dowel bolt driving hole drilled in the casing through the housing of the third bearing; at least one nut consisting of a dowel bolt and a nut; and a set of position fixing members; said position fixing members prevent relative movement of the bearing housing with respect to the casing during use from a coupled position set and tightened by said position fixing members. A positioning structure for a bearing housing such as a rotating electric machine having three or more bearings. (2) Utility Model Registration In the bearing housing positioning structure set forth in claim 1, the knock bolt driving hole is a tapered hole whose diameter decreases from the front side of the bearing housing toward the driving direction, and the The side of the shaft of the knock bolt near the tip is tapered to be almost the same as the taper hole, and the relative movement of the bearing housing with respect to the casing is firmly restrained by press-fitting the knock bolt into the tapered hole. Positioning of the bearing housing. structure.
