的とするフアンモーターの取付構造に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a structure for mounting a fan motor for the purpose of cooling and blowing air into parts inside a container.
従来技術の構成とその問題点
従来より、第１図に示す如くフアンモーター１

When installing the fan motor 1 to the fan body 2, fix it to the metal mounting plate 6 with fastening screws 5 in the mounting hole 4 provided in the iron core 3 of the fan motor 1.
A common method is to fix the motor to the body 2 with a body fastening screw 8 via a motor vibration isolating rubber 7 or the like.

対する設計的配慮も必要である。 In this case, design considerations must first be made to minimize changes in the characteristics of the fan motor 1 due to leakage magnetic flux in terms of performance, and when the fan motor 1 rotates, it is necessary to The structure must be such that vibrations caused by unbalance are not transmitted to the vessel body 2.
The reason for the former is to reduce the number of revolutions of the fan motor 1, and the latter is to prevent abnormal noise from occurring due to vibration of the fan motor 1. In addition, at this time, it is necessary to take into consideration in design the increase in the number of parts to eliminate the above-mentioned defects, the selection of materials used, and the increase in cost due to an increase in the number of assembly steps.

計的に非常に困難なものである。 However, as one of the most effective means to reduce the leakage magnetic flux passing through the metal mounting plate 6 from the fan motor 1, it is recommended to replace the metal mounting plate 6 with a non-magnetic material such as austenitic stainless steel, aluminum, copper or copper. There are alloys, but they are all expensive materials and have a big disadvantage in terms of cost. Furthermore, the vibration of the fan motor 1 caused by the unbalance of the fan 9 can be improved by dynamically balancing the fan 9, but when actually considering mass production and cost,
Not desirable. Therefore, it is necessary to fasten the fan motor 1 through an elastic body such as rubber so that the fan motor 1 has a vibration-proof structure that does not transmit the vibration to the device body 2 and generate abnormal noise even if it vibrates. At this time, it is possible to reduce the vibration by keeping the rotation speed of the fan motor 1 low, but this would actually be extremely difficult in terms of design since the original purpose of cooling and air blowing ability would be reduced. It is something.

When attaching the fan motor to the body, a simple configuration of inserting a resin mounting bracket between the two prevents the performance of the fan motor 1 from decreasing due to leakage magnetic flux, or from unbalance of the fan 9. suppresses the transmission of vibrations to the vessel body 2,
Moreover, the aim is to achieve this at low cost.

The mounting bracket 10 made of resin is fixed with a fastening screw 5 using the mounting hole 4 provided in advance, and the mounting bracket 10 is fixed to the vessel body 2 with a body fastening screw 8. . At this time, the mounting bracket 10 is provided with a plurality of bosses 11a and 11ro, and the bosses 11a and 11b are provided on the mounting surface of the iron core 3.
There are bosses 11a that come in contact when left unattended, and bosses 11ro of different heights that are placed with a gap t when left unattended, and the fan motor 1 is placed with a gap t provided by motor fastening screws 5. It is fixed on the boss 11ro side. Further, as shown in Fig. 3, bosses 11a or 11ro are arranged diagonally at A and D of the motor core with respect to the mounting holes 4 previously provided in the iron core 3 of the fan motor 1. The other bosses arranged at A and C are arranged at C, and the fan motor 1 is connected to the motor fastening screw 5.
It is fixed at the bottom part of the boss 11.

効果は絶大である。 As for the operation of the above-mentioned configuration, as shown in FIG. 4, which is a view seen from the direction of the arrow in FIG. It is fixed to the boss 11ro of the bracket 10. At this time, since the boss 11 is arranged with a gap t, when the motor fastening screw 5 is tightened, the resin bracket 10 is deformed within the elastic limit by the gap t and tightly adheres to the iron core 3. do. In other words, if the motor fastening screws 5 are tightened, the mounting bracket 10 permanently fixes the iron core part 3 through its own elasticity. By absorbing the vibrations of the fan motor 1, not only will the vibrations not be transmitted to the vessel body 2 and unpleasant abnormal noises will not be generated, but also the characteristic of resin is that it does not transmit magnetic flux, so the body Since the leakage magnetic flux to the fan motor 2 can be almost ignored, there is no deterioration in the characteristics of the fan motor 1, and the resin material itself can be supplied at a very low cost compared to metal non-magnetic materials. Moreover, since the number of parts is small, the effect is tremendous.

向上する事が可能である。 At this time, in order to reduce assembly workability and man-hours, as shown in FIG. 12 makes it easier to position the fan motor 1 and the mounting bracket 10 when tightening the motor fastening screws 5, and work efficiency is significantly improved. Moreover, FIGS. 6 and 7 are examples of its application, and are its original purpose. In addition to preventing deterioration of characteristics due to the vibration-proof structure and leakage magnetic flux, it is possible to reduce the number of mounting screws and man-hours. In this configuration, as shown in FIGS. 6 and 7, the mounting bracket 10 is provided with a stepped portion 12 or a recessed portion 13 shaped to lock or engage with the motor core 3, etc., and the stepped portion 12 is provided as shown in FIG. Alternatively, the motor fastening screw 5 is arranged at a position 14 opposite to the recess 13. Mounting bracket 10 like this
When attaching the fan motor 1 to the body 2 via the fan motor 1, as shown in FIG. By providing an opening 15 approximately in the center of 10,
As shown in FIG. 10, when installed on the fan body 2, by increasing the area of the intake opening 16 provided in the fan body 2, the fan motor 1 is able to draw air for cooling and blowing air, which is the original purpose of the fan motor 1. It is also easily possible to reduce the resistance and make maximum use of the performance of the fan motor 1. Moreover, it is possible to easily cool down the temperature rise of each part of the fan motor 1 itself, especially the winding 17 and the bearing part 18, which is the life part of the motor, and the reliability can be greatly improved.
