FIG. 1 is a structural sectional view showing a bearing device for a rotating machine according to an embodiment of the present invention, and FIG. 2 is a structural sectional view showing a conventional bearing device for a rotating machine. In the figure, 1 is a frame, 2 is a stator, 3 is a winding, 4 is a rotor, 5 is a bracket, 6 is a bearing,
7 is a rotating shaft, 8 is a ventilation passage a provided in the rotating shaft 7, 9
is a ventilation passage b provided in the axle box of the bracket 5. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.
Claims (1)
風路を有する回転軸と、この回転軸の通風路は遊
び側、負荷側双方の軸受とブラケツトの間に位置
する回転軸の円周方向に連通するよう形成し、か
つブラケツトの軸箱部に通風路を有することを特
徴とする回転機の軸受装置。 The rotary shaft has a hollow ventilation passage in the axial direction from the end of the shaft on the play side of the rotating machine, and the ventilation passage of the rotary shaft extends around the circumference of the rotation shaft located between the bearing and the bracket on both the play side and the load side. What is claimed is: 1. A bearing device for a rotating machine, characterized in that the bearing device is formed so as to communicate in the direction and has a ventilation passage in an axle box portion of a bracket.
