Abstract

PROBLEM TO BE SOLVED: To simplify a press tool, share a bracket, and improve productivity by attaching a support plate. SOLUTION: In a bracket 1, a flange having no bearing protruding part press-molded with a steel plate is installed. In the bracket 1, a support plate 5 having a protruding part press-molded with a steel plate is attached to the end surface of the axial direction of a motor, so as to have the same form as a bracket having a bearing protruding part. By attaching the support plate 5, a press tool is simplified, a bracket can be shared, and productivity can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric motor for driving a fan, and more particularly to a structure of a bracket for preventing a plurality of brackets from being attached to a counterpart device due to a method of attaching the bracket to a partner device.

[0002]

2. Description of the Related Art A method for fixing a fan driving motor having a bracket press-formed from a steel plate includes a method in which a flange is provided on an outer peripheral portion of the bracket, a hole is formed in the flange, and the bracket is fixed to a partner device with a screw or the like. is there. Also, as described in Japanese Patent Application No. 2-29243, a vibration isolating rubber is fitted to a bracket having a bearing portion protruding from an axial end surface of the electric motor, and a fastening bracket is interposed through the vibration isolating rubber. There is a method of fixing to the mounting base with.

[0003] In the prior art, a bracket provided with a flange for fixing to a counterpart device with a screw or the like as described above does not have a bearing portion protruding from an axial end face, and has a bearing portion protrusion. The bracket is not provided with a flange for fixing to a partner device with a screw or the like. These brackets must have separate press forming dies, and having two press forming dies requires a large amount of manufacturing cost and a long manufacturing time. It has been necessary for a long time to replace the press molding dies with the press machine, which has hindered the improvement of the production capacity in the production process.

[0004]

In the above-mentioned prior art, press molding dies for the brackets must be manufactured due to differences in the method of attaching the fan driving motor to the counterpart device. Long production days are required, and in the production process, it is necessary to replace the press-molding dies with the press machine for a long time, which hinders the improvement of the production capacity in the production process.

An object of the present invention is to solve these problems.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bracket provided with a flange having no bearing projection formed by press-forming a steel plate and a separate steel plate. A support plate having a press-formed protrusion is fixed to the axial end face of the electric motor by caulking with a rivet or the like, so that it has the same shape as a bracket having a bearing protrusion. , Brackets can be shared, and production capacity can be improved.

In order to attach a support plate press-formed separately from a steel plate to a bracket provided with a flange having no bearing projection formed from a steel plate, the support plate is fixed by caulking with a rivet or the like. Some holes need to be machined. This requires only a part of the press-molding process, and requires a support plate press-molding die. However, since the support plate has a simple structure and does not require a complicated press-forming die. It can be manufactured at low cost. Even if these steps are added and a press-molding die is added, it is cheaper and easier than manufacturing a press-molding die exclusively for brackets having a bearing protrusion.

As described in the above-mentioned prior art, there is a great effect in solving the problem of having two press-molding dies due to a difference in a method of attaching a fan driving motor to a partner device.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a bracket 1 provided with a flange not having a bearing projection formed by pressing a steel plate, and a support plate 5 having a projection 6 separately formed by pressing a steel plate to a shaft of an electric motor. 2 is a front view of FIG. 1, and FIG. 3 is a cross-sectional view of FIG.

FIG. 4 shows a projection 6 press-formed from a steel plate.
FIG. 5 is a front view of FIG.

FIG. 6 is a view of a bracket 1 provided with a flange having no bearing projection formed by pressing a steel plate, and FIG. 7 shows a support plate 5 attached to the bracket 1 of FIG. It is the front view which processed the hole 7 for crimping and fixing.

The bracket 1 does not project the bearing 2 on the axial end face of the electric motor like the bearing projection 11 of the bracket 10. Therefore, the support plate 5 having the projection 6 is fixed by caulking with the rivet 9. Accordingly, the same shape as the bracket 10 having the bearing protrusion 11 can be obtained. In order to fix the support plate 5 with the rivet 9 by caulking the bracket 1, it is necessary to additionally form a hole 7. The hole 7 of the bracket 1 and the hole 8 of the support plate 5 which have been additionally processed are provided at several places, and each is located at the same position. Hole 7 in bracket 1
And caulked and fixed with rivets 9 through holes 8 in the support plate 5. The counterpart device mounting hole 4 is opened at the time of press forming.

The bracket 1 and the support plate 5 are rivet 9
By caulking and fixing, the shape becomes the same as that of the bracket 10 having the bearing projection 11, and the effects of simplifying the press-molding die, sharing the bracket, and improving the production capacity are very significant. large.

[0015]

According to the present invention, a support plate having a projecting portion press-formed separately from a steel plate is attached to a bracket provided with a flange having no bearing protrusion formed from a steel plate. Accordingly, the same shape as the bracket having the bearing protrusion can be achieved, which simplifies the press-molding die, shares the bracket, and improves the production capacity.
