(Prior art and its problems) For cylindrical impellers used in various air-conditioning equipment, the configuration of the rotating shaft support is important. For example, if motor vibrations cannot be effectively absorbed and attenuated, noise may be generated. This may cause inconveniences such as shortening of life or shortening of service life.

For this reason, conventionally, the rim for supporting the blades constituting the shaft support member and the shaft support part are connected by a bypass connecting member to mechanically enable elastic deformation, thereby absorbing and attenuating the vibrations, etc. Attempts are being made. (For example, Japanese Patent Application Laid-Open No. 58-15794 or
(See Japanese Patent Publication No. 48-31464) The detour direction of such a conventional shaft support member is either the axial direction or the rotational direction. In the conventional example described above, the former is an axial detour, and the latter is a rotational detour. In this way, if the detour direction is in one direction, the structure can be configured to have high elastic deformability in either the axial direction or the rotational direction, but it can be configured to have high elastic deformability in both directions without losing strength. It cannot be configured to do so. The conventional examples described above all have high elastic deformability in the axial direction, but low elastic deformability in the rotational direction.

By the way, in the shaft support member, when the motor is started or stopped, a relatively strong rotational force may be applied between the shaft support portion and the blade supporting rim due to the inertia of the impeller. There is also a need to be able to relatively elastically move in the direction of rotation in order to absorb such rotational force. To solve this problem, there is a configuration in which the connecting member is detoured only in the rotational direction, but this has the disadvantage that when it moves relative in the rotational direction, it also moves relatively in the axial direction, and the connection member in other directions also moves relatively. It is not possible to improve elastic deformability at the same time.

The present invention aims to solve the above problems in a very rational manner.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the shaft support member of the present invention comprises a shaft support portion coaxially spaced from the inner side of the blade supporting rim, and A connecting member is connected to the gap between the support portion and the blade supporting rim, and the connecting member is formed into an annular shape by alternately bending the band-shaped body in the axial direction, and the connecting member is connected to the blade supporting rim side. The gist is that the position and the connection position on the shaft support part side are shifted in the rotational direction.

(Function) As described above, in the present invention, the connecting member is formed into an annular shape by alternately bending the band-shaped bodies in the axial direction, and the connecting position on the blade supporting rim side and the connecting position on the shaft supporting part side are different from each other. Since it is shifted in the direction of rotation,
The connecting member can connect the shaft support part and the blade support rim in a detour in both the axial and rotational directions, so that the shaft support part and the blade support rim can be connected in both the axial and rotational directions. It has relatively high elastic deformability, so it can absorb and damp the transmission of vibration between the shaft support part and the blade support rim, and also prevent the relatively strong rotational force generated between them in the axial direction. can be effectively absorbed without causing any relative movement of the particles. And it doesn't lose strength.

Reference numeral 1 denotes a blade support rim, and a shaft support part 2 is coaxially spaced from the inside of the blade support rim 1.
A connecting member 3 is connected to the gap between the shaft support portion 2 and the blade supporting rim 1. The connecting member 3 is formed into an annular shape by alternately bending band-shaped bodies in the axial direction, and the blade supporting rim 1
The connection position on the side and the connection position on the shaft support part 2 side are shifted in the rotational direction. In the embodiment shown in FIG. 1, there is a single connecting member 3, but in the embodiment shown in FIG. 2, there is a plurality of connecting members 3. In the latter case as well, each of the connecting members 3 has a connecting position on the blade supporting rim 1 side, and
The connection position on the shaft support part 2 side is shifted in the rotational direction. The above members can be easily constructed, for example, by integral molding of synthetic resin. The shaft support member of the present invention may have a structure in which an end plate 5 for attaching the blade 4 is separately provided on the outer periphery as shown in FIG. It may also be configured to be attached to the outer periphery of the rim 1 itself. In the illustrated example, reference numeral 6 denotes a ring-shaped reinforcing rib formed as appropriate on the blade supporting rim 1.

Therefore, in the shaft support member configured as described above, the shaft support part 2 and the blade support rim 1 are connected via the connection member 3 in a detour in the axial direction and rotational direction, so that Both have excellent elastic deformability and can therefore effectively absorb and attenuate vibrations transmitted from the motor. Moreover, even when a relatively strong rotational force is applied between the shaft support part 2 and the blade support rim 1 due to the inertia of the blade support rim 1, such as when starting or stopping the motor, the This can be absorbed by elastic deformation only in the direction, and the shaft support portion 2 and the blade support rim 1 do not move relative to each other in the axial direction, unlike in a configuration in which the connecting member is detoured only in the rotation direction. Failures caused by movement can also be prevented.
