は直径数百間もあり、毎分数百回転で回転する。A conventional plastic 7-inch box will be explained with reference to FIGS. 1 and 2. The 1st vA glass fan h is formed by integrally molding a main plate 1 which is bent into a dish shape and has a nine circular shape, and a large number of blades 2, and the blades, t12#i, are 2 pages wide on the suction side and narrow on the outlet side. The annular side plate 3 in the shape of a truncated cone is bonded to the other end of the wing a2 with a JK adhesive solvent, and the rotating shaft 4 is inserted and fixed into the boss 1a at the center of the main plate 1. The main plate 11 and the blade 12 are similar to those shown in FIG.
are integrally molded, and the annular side plate 13 is attached to the blade 1 by ultrasonic bonding.
It is connected to the other end of 2. The blade 12IIi is formed to have the same width on both the suction side and the outlet side. 11at;! The boss shows the 14Fi rotation axis. The large fans mentioned above have a diameter of several hundred meters and rotate at several hundred revolutions per minute.

ましいが、通常は羽根と主板あるいは羽根と側板の少な
く４一方を接合して製作している。In general, it is desirable for plastic fans to be made entirely in one piece from the standpoint of mass production and precision, if possible, but usually they are made by joining the blades and the main plate, or the blades and the side plates, at least four sides. .

できず、接着溶剤による接合を行なわざるを得ない０こ
の接合は、全数の羽根について行なわれるが、接着溶剤
の一箇所当りの使用量を均等、、にすることは難しい。The 7-inch structure shown in Figures 1 and 2 is defined as a 0-wing machine formed by joining the blades and side plates as described above, and for performance reasons, the width of the outlet part is the width of the inlet part. The first narrower compared to
The shape shown in the figure is desirable, but in this case, the joint surface 5 is inclined with respect to the main plate 1. Therefore, ultrasonic bonding is not possible, and bonding with an adhesive solvent has to be performed.This bonding is performed on all blades, but the amount of adhesive solvent used per location should be equalized. That's difficult.
また、接着接合は、超音波接合の場合より回転アンバラ

それ以前の問題として、振動損幅が大きいと静止部に接
触して破損し九や、騒音が大きくなる問題点を有する。In addition, with adhesive bonding, the change in rotational unbalance over time is greater than with ultrasonic bonding. If this rotational unbalance is not minimized, a vibration mode with a single diameter node will occur during operation, which will cause rotation Repeated stress is generated in the boss portion 1a to which the shaft is attached and the rotating shaft 4. If this vibration is large, there is a risk of fatigue failure of the rotating shaft 4 and the boss portion 1a,
As a problem before that, if the vibration loss width is large, there are problems such as contact with stationary parts and damage, and increase noise.
このため、回転アンバランスを最小限にするためにダイ
ナミックバランスが取“られている。しかし乍ら、初期
の接着溶剤の重量不均一に起因する回転アンバランスは
減らすことが出来るが、経年変化により、生じる回転ア
ンバランスを減らすことは困難である。For this reason, dynamic balance is taken to minimize the rotational unbalance.However, although the rotational unbalance caused by the uneven weight of the initial adhesive solvent can be reduced, due to aging , it is difficult to reduce the resulting rotational imbalance.

しては、接合部を超音波接合−によるものが知られてい
る。超音波接合は、接合面に超音波エネルギーを集中さ
せ、その発熱により母材を溶して接合するため、荷重を
加えなければならない・。Japanese Unexamined Patent Publication No. 58-35296 (2) It is known that the joining portion is ultrasonic bonded as a method in which the increase in rotational unbalance due to aging is small. In ultrasonic bonding, ultrasonic energy is concentrated on the bonding surface, and the heat generated melts the base materials to form a bond, so a load must be applied.

I'm worried. At the seventh ninth point, 1 main plate 11 as shown in Figure 2.
The joint surface 15 must be formed parallel to . Therefore, in the blade shape, the width of the inlet portion and the width of the outlet portion are the same. If the widths of the inlet and outlet are the same, the outlet area will be larger than the inlet area, resulting in poor performance. Furthermore, the flow of gas is
Since the direction is suddenly changed by 90 degrees at the blade part, the flow (9) occurs, which causes a decrease in performance and an increase in noise.

め、性能低下および騒音増加が問題であり、いずれも一
長一短であった。As mentioned above, the adhesive-solvent bonded glass fan shown in Figure 1 has good performance, but due to the increase in rotational imbalance due to aging, reliability in terms of strength and vibration becomes a problem. In addition, as shown in Figure 2, the glass fan made by ultrasonic bonding has a small increase in rotational amplitude due to aging, but since the blades are the same size, there are problems with performance deterioration and noise increase. It also had its pros and cons.

目的とする。The present invention was invented in view of the above, and enables ultrasonic bonding even when the width of the blade is wide at the inlet and narrow at the outlet, thereby preventing an increase in rotational imbalance due to aging. It is an object of the present invention to provide a glass fan that has a small amount of noise and is free from performance deterioration and noise increase due to flow separation, etc.

する。To achieve the above object, the present invention provides a joint surface between the annular side plate and the blade, or a joint surface between the main plate and the blade, in which the blade width is narrower at the outlet than at the inlet and is formed obliquely with respect to the main plate. A stepped joint surface is formed by combining parallel and perpendicular surfaces to the main plate or side plate, and among the stepped joint surfaces,
It has the feature of ultrasonically welding the planes parallel to the main plate or side plates.

２５ｂ 、 ２５ｅ。An example of a plastic fan of the present invention will be explained based on FIG. 3. The figure shows an enlarged cross-sectional view of the main plate portion and side plate portion that are joined to the blades and the blade, and the other portions are shown in 1a! Although it is the same as 0, illustration and explanation thereof will be omitted. The main plate 21 and a large number of blades 22Fi are integrally formed. The width 22m of the inlet part of the blade 22#1 is larger than the width 22b of the outlet part, so the IwL connecting the edge of the opposite side of the main plate 21, that is, the side plate side, is different from the conventional one on the main plate 1 side. Corresponding to FIG. 1, it is formed roughly in an inclined shape. The edge forms a plurality of stepped joint surfaces 6 along line LK. That is, a surface 25m parallel to the main plate 21,

A joint surface is formed that is completely symmetrical to the edge. That is, the planes 25m and 25b of the blade ρ parallel to the main plate 1
, 25e, 25d and perpendicular 11i
Step-like joints rIjJ symmetrical to the blades are formed on the surfaces joining 26m, 26b, and 26@. As shown in the figure, the outer wall surface of the biita field is also formed in a step-like shape corresponding to the joint surface.

ば抛物線的にすることも可能である。A 3J-shaped side plate 7 n is engaged with the edges of a large number of blades n having the above-mentioned shape, and the joining surfaces of both are joined by ultrasonic welding. Therefore, as mentioned above, the joint surfaces are formed with surfaces 25m, 25b, 25e, and 25d that also serve as the main plate IK, so that a sufficient load can be applied to the joint surfaces without the pressing force escaping, and a reliable Ultrasonic bonding is possible. At this time, the vertical surfaces 26m + 26b * 26a are in close contact with each other without any gaps, and in terms of strength, it is sufficient that they do not need to be joined. The blade shape is diagonal as in the conventional example shown in Figure 1.
Since it is preferable in terms of performance, if the size and interval of the steps on the joint surface shown in FIG. 3 are made as small as possible, that is, if they are made into a fine step shape, the shape can be approximated to the shape shown in FIG. 1. Plastic fans are manufactured by injection molding using a mold, so the fine shape of the joint surface poses no problem in manufacturing once the mold is completed. Furthermore, the edge connection @L of the joint surface on the side plate side can be made not only in the diagonal straight line shown in FIG. 3 but also in a parabolic line shape if necessary.

According to the invention, blades having narrow widths on the inflow side and the outflow side can be joined using ultrasonic waves, which eliminates problems such as rotational unbalance that increases over time, and also reduces performance and increases noise due to separation of fluid flow. You can get a nice plastic fan.
