せを行なつたうえで運転を行なう必要がある。 This coupling connects one of the flanges 1a, 1b to a drive shaft (not shown) and the other to a driven shaft to transmit torque, and also uses elastic deformation of diaphragms 3a, 3b, etc. to center the two shafts. It absorbs misalignment, etc., but if the misalignment exceeds the allowable value, there is a risk that the diaphragms 3a and 3b will be damaged in a short period of time, so measure the amount of misalignment using a dial gauge etc. when the diaphragm is stationary. However, it is necessary to perform alignment before operation.

In order to solve the above problems, the present invention provides a coupling ring in which a center tube is coaxially connected between a pair of flanges facing each other in the axial direction via a diaphragm, and a disk member is coaxially connected to the outer periphery of the center tube. It has a structure in which one side of the disk member faces the flange side member with an appropriate gap in between.

In the above configuration, if there is misalignment between the flanges, the center tube between the flanges will be angularly displaced, and the disk member fixed to the center tube will also be displaced relative to the flange side member. and is angularly displaced at the same angle as the displacement angle of the center tube. Therefore, if the gap between the disc member and the flange side member is set in advance so that the opposing parts of the disc member and the flange side member come into contact when the displacement angle reaches a predetermined value, the two members It is possible to determine whether or not the amount of misalignment, etc. has reached an allowable value by simply monitoring whether or not they are in contact.

Under normal conditions without misalignment, the first
As shown in the figure, it faces parallel to a guard member 4a fixed to the flange 1a side with a gap 9 interposed therebetween. The other components of the coupling are as follows:
Since this is no different from the conventional example described above, the same reference numerals as in FIG. 3 will be used and the explanation thereof will be omitted.

できる。 In the above configuration, when the axes of the flanges 1a and 1b are misaligned with each other, as shown in FIG. The disc member 7 is angularly displaced. Therefore, when the magnitude of misalignment reaches the allowable value When the displacement angle of the disk member 7 with respect to 4a reaches the allowable angle θ, the disk member 7
If the size of the gap 9 is set in advance so that a part of the outer circumferential edge 7' of the guard member 4a comes into contact with the guard member 4a, it is possible to determine whether or not the two members 7 and 4a are in contact when stopped. Of course, even during operation, it is possible to easily monitor whether the amount of misalignment, etc. has reached an allowable value.
