Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a motor used, for example, in a cooling fan for an automobile.

[Conventional technology]

As is well known, a dedicated motor is sometimes installed in order to send cooling air to an automobile radiator. This motor is attached to a motor mounting part in an automobile. The mounting dimensions and position of the motor in this motor mounting part vary depending on the contact relationship with vehicle parts and the wiring position of the motor, so even when using a motor of the same capacity, the mounting bracket may have a different mounting position depending on the vehicle. It is attached via.

Conventionally, as a mounting structure of a mounting bracket for this type of motor, the structure shown in, for example, Japanese Utility Model Application Laid-Open No. 55-19449 or shown in FIG. 5 has been known.

In FIG. 5, a represents a motor, and this motor a has a frame b and a mounting bracket d. A rotor and the like are built inside the frame b, and a shaft c that is connected to the rotor protrudes. or,
The mounting bracket d consists of a cylindrical part e having a slightly larger diameter than the outer diameter of the frame b, an annular flange part i connected to the cylindrical part e, and three protrusions formed on the outside of the annular flange part i. It is formed by a portion f and a mounting hole g formed in each protrusion f.

The frame b and the mounting bracket d are originally separate parts. Then, a mounting bracket d is attached to the frame b, as shown in FIGS. 5A and 5B. To do this, first insert the frame b into the cylindrical part e of the mounting bracket d. Then, in order to mount and fix the motor a in a predetermined position, the relative position of the frame b and the mounting bracket d is determined according to the position of the motor mounting part in the automobile, and the cylindrical part e of the mounting bracket d is Perform spotting h over the location. Thereafter, the parts constituting the motor a are housed in the frame b.

[The problem that the idea attempts to solve]

However, in the above-described mounting structure between frame b and mounting bracket d, frame b and mounting bracket d are fixed with spot attachments h, so motor a must be completed with mounting bracket d attached. .
Therefore, a jig is required for each mounting bracket d, making the process cumbersome. Furthermore, since the type of vehicle is determined at the initial stage of assembling the motor a, there is a drawback that it is difficult to respond to the demands of the customer. That is, in the conventional method, a frame b is prepared in advance to which a mounting bracket d is attached by spot welding or the like, and component parts such as a rotor are housed in this frame to form a motor a.
In order to change the mounting bracket d, it was necessary to replace the frame b itself.

The present invention was devised to solve these conventional problems, and its purpose is to provide a motor that has a simple manufacturing process and is highly responsive to the demands of its customers.
