JPH08214485A - Method for mounting motor on casing, or the like - Google Patents

Abstract

PURPOSE: To provide a method by which a motor having a relatively large size can be mounted on the casing of an air blower so that the electromagnetic vibrations, etc., of the motor can be damped and absorbed for a long period. CONSTITUTION: At the time of mounting a motor having a relatively large size on the casing of an air blower, a mounting member 1 is used. The member 1 is constituted of a motor-side member 11, casing-side member 13, and elastic body which unites both members in one body by sticking both members. The mounting member 1 is fixed to the casing by using several screws to the outer peripheral section of a mounting hole 5 after inserting the member 1 into the bearing section 21 of the output shaft of the motor and putting the member 1 in the mounting hole 5 of the casing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a motor on a casing or the like.

[0002]

2. Description of the Related Art Conventionally, in a method of mounting a motor on a blower, the motor is mounted on a casing or the like by various kinds of devices. For example, in the case of a small motor, it is sufficient to directly attach it to the casing with a screw and fix it, but in the case of a relatively large motor, it is necessary to fix the motor and absorb the vibration, so that it is shown in FIG. As described above, the rubber part is inserted between the motor and the casing to fix the motor with the rubber part from both sides and absorb the vibration.

However, in the method of mounting the large-sized motor, the rubber part is deformed by the weight of the motor, and a gap is formed between the rubber part and the bearing portion of the motor or between the rubber part and the mounting hole of the casing. There have been problems such as compression set increasing in rubber parts due to changes over time, the fixing of the motor becomes unstable, and the effect of damping vibration decreases.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, the present invention provides a method of mounting a motor for a blower,
To provide a motor mounting method that uses an elastic body that absorbs vibration in a member that fixes a motor to a casing, and that maintains stable vibration absorption performance for a long period of time.
That is the subject.

[0005]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above problems, and has a structure in which, in a blower composed of an impeller, a casing, and a motor, a hole fitted into a bearing portion of the motor is provided. Characterized in that an elastic member is fixedly integrated between a member that is formed so as to be fixed to the motor and that can be fixed to the casing by fitting into a motor mounting hole of the casing. I am trying.

In the present invention, the mounting member is
It is characterized in that the elastic member is fixed between two members having an L-shaped cross section, and the mounting member is integrated.

In the present invention, the outer plate of the L-shaped member is attached to the motor bearing portion and the motor main body, and the inner plate of the other L-shaped member is attached to the casing or the like. It is characterized by that.

[0008]

According to the present invention, by fixing the elastic body to the central portion of the member for mounting the motor, the elastic body damps and absorbs the vibration of the motor and the cross flow fan, and the elastic body is deformed by the weight of the motor. Since the weight of the motor is held by the entire fixing surface between the member and the elastic body against the force to be exerted, it is possible to eliminate the gap due to partial compressive strain or the like.

[0009]

EXAMPLE An example of the present invention will be described with reference to FIGS. In FIG. 1, 1 is a mounting member that is fitted and fixed between the motor and the casing, 2 is a motor, and 3 is a casing. Mounting member 1 is a motor side member (outer side plate)
11 and a casing side member (inner side plate) 13, and an elastic body 12 for fixing both members. As the member 11, a metal plate such as a steel plate or an aluminum plate is appropriately selected and used. The thickness of the elastic body is preferably about 3 to 6 times that of the member 11 or the member 13, and the material may be neoprene rubber, urethane rubber, or the like. Member 11, 1
3 and the elastic body 12 may be fixed to each other by a baking method, a method using an adhesive, or the like, and any method can be used as long as it can prevent peeling when a load is applied.

As a first embodiment, a case where the motor has one output shaft will be described with reference to FIG. One end of the L-shaped outer side plate 11 of the mounting member 1 is fitted to the bearing part 21 of the motor output shaft so that one end of the outer side plate 11 is on the motor side, and the other end of the outer side plate is attached to the motor outer peripheral part using several screws The member 1 is fixed.
Next, the inner plate 1 of the mounting member 1 is inserted into the mounting hole 5 of the casing.
One end of 3 is fitted and brought into contact with the other end, and the other end is fixed to the casing with several screws on the outer peripheral portion of the mounting hole 5, and the motor is attached to the casing. Although not shown, for example, a cross flow fan or the like is connected to the output shaft of the motor using a coupling or the like.

As a second embodiment, a case where the motor has two output shafts will be described with reference to FIG. The mounting member 1 is fitted to the bearing portions 21 of the left and right motor output shafts, and the motor 2 and the mounting member 1 are fixed with one or several screws. Next, the mounting members 1 are fitted into the mounting holes 5 of the casing, and the mounting member 1 and the casing are fixed with one or several screws. The fixing screw of the second embodiment is for preventing the motor from rotating due to the load.

[0012]

As described above, according to the present invention, when the motor is mounted on the casing, the mounting member having the elastic body fixed thereto is used. It becomes possible to continue.
