本考案は、大形立軸機械例えば立形水車発電機
の推力軸受を装着する分割形ブラケツトの改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a split bracket for mounting a thrust bearing of a large vertical shaft machine, such as a vertical water turbine generator.

する必要がある。このためブラケツト自身の剛性
を高める必要がある。 As the capacity of the generator increases, the bracket also becomes larger, and due to size and weight transportation limitations, it is manufactured by cutting the arm and dividing the body, and is finally integrated by bolting. Brackets for large-capacity aircraft must support thrust bearing loads of, for example, several thousand tons. For this reason, it is necessary to increase the rigidity of the bracket itself.

As shown in the figure, there is a ring-shaped body 1 that is vertically divided into two parts 1a and 1b, an arm 2 that transmits the load, a reinforcing plate 3 that extends radially, and a plate that joins the arm 2 and the body 1. 4. It consists of an arm and a joining plate 5 provided between the arms to unite the body. This structure has the disadvantage that a sufficiently thick plate must be used as the joint plate 5 to provide sufficient rigidity to the weak joint, and it must be tightened with a large number of bolts 6.

部に設けるのが本考案の特徴である。 An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. As shown in Fig. 3, a ring-shaped body 1 is vertically divided into two parts 1a and 1b, an arm 2 that transmits the load, a reinforcing plate 3 that extends radially, and a plate that joins the arm 2 and the body 1. 4. Consists of a joining plate 5 provided to unite the trunk 1 at the center of the arm, and the divided trunks 1a, 1b and the joint between the trunk 1 and the arm 2 are connected with bolts 6, 7. Tighten as one piece. Reference numeral 8 denotes knock pins that are provided at the upper and lower ends of the joint portion, facing downward and upward, respectively. At this time, the arm 2 is tightened and fixed across both the divided body parts 1a and 1b with bolts 7 and dowel pins 8, and the feature of the present invention is that the dowel pins 8 are provided at least at the lower end portion on the tensile force side.
図においてアーム２は４本、胴部分割は２ケ所
であるが、これが他の数であつても同様にアーム
接合板４を胴部接合板５の位置に合わせれば良
い。 In the figure, there are four arms 2 and two body parts, but even if there are other numbers, the arm joint plate 4 may be aligned with the body part joint plate 5 in the same way.
この様な構成を行うことにより胴部１の接合力

重量軽減並びにコストの大幅な低減を達成するこ
とが出来る。 With such a configuration, the clamping force of the arm 2 and the shearing force of the knock pin 8 are added to the joining force of the body 1, and the thickness of the body joint plate 5 is reduced by this amount in order to transmit and support the arm. At the same time, the size and number of bolts 6 can be reduced as shown in FIG. This makes it possible to reduce the weight of the bracket and significantly reduce costs.
