ことを特徴とする球面支持された軸受の位置決め装置。A fixed bearing consisting of an upper half and a lower half, the outer diameter part of which is formed into a spherical shape, and an annular groove with a semicircular cross section is provided in the center of the spherical part in the circumferential direction. The shaft is fixed to the bearing support side of the shaft, and the inner peripheral part is formed into a spherical shape that corresponds to and contacts the spherical part of the bearing, and receives the bearing from the lower side. A pad provided with a positioning groove in the center with respect to the direction and from the top to the center in the circumferential direction, and a positioning sphere inserted between the annular groove in the lower half of the bearing and the positioning groove in the pad. The semicircular shape of the annular groove is slightly larger than the outer diameter of the spherical body, and the width of the annular groove of the pad is slightly larger than the diameter of the spherical body, so that the bearing can be self-aligned. A positioning device for a spherically supported bearing, characterized by directional positioning.
