Description

[Detailed Description of the Invention] In the present invention, the mounting of the motor is related to the structure, and more specifically, the mounting of the motor to the bracket is related to the structure.

A conventional motor 1 is attached to a bracket 2 as shown in FIG.

To assemble the motor 1 and attach it to the bracket 2, cover the motor case 3 with side covers 4, 4 from both sides, as shown in FIG.
By inserting and bending, as shown in Figure 2,
It was something to be assembled.

The motor 1 assembled in this way is attached to the bracket 2.
When mounting the brackets 2 to 21, etc., as shown in Fig. 3, insert the motor 1 and bracket 2 into the screw holes 3' on the side of the motor case 3, which are aligned with the holes 2'. After assembly, it was installed by inserting and tightening screw 6, which caused the following problems.

■ The machinability of screw hole 3' to motor case 3 is poor.

■ At times, when attaching the motor 1 to the brackets 2 to 21, etc., it is difficult to tighten the screws 6.

■ The screw hole 3' of the motor case 3 and the new material of the brackets 2 to 21 are different in hole position from the hole 2'. When connecting to external mechanism A, there were problems such as locking, vibration noise, and reduced transmission efficiency.

The present invention was developed to solve the above-mentioned problems, and when installing the motor to the bracket, a bushing is attached to the bearing parts protruding from both ends of the motor case, and the bushing is formed on the bracket. It is held in the claw part, which reduces the work involved in drilling screw holes and tightening screws, and provides a structure for mounting the motor that makes it easy to center the motor shaft and has a high vibration-proofing effect. be.

Hereinafter, an example of the structure of mounting the motor according to the present invention will be explained based on the drawings.

In Fig. 4, reference numeral 31 denotes a motor case of the motor according to the present invention, which has bearing parts 31', 31'' protruding from both ends, and bushings 8, 8 to 9, 8 are attached to the bearing parts 31', 31''. Side covers 41, 4 are inserted and provided with a raised edge 41' around the periphery and an H-shaped protrusion 41'' on the inner surface.
1 on both sides of the motor case 31, and the belt-shaped cushioning material 10
The side covers 41 and 41 are fixed to the motor case 31 by wrapping and pasting them with the adhesive applied side facing inside.

Figure 5 shows the bracket, and the bracket? , 71 are formed by cutting and raising a holder for holding the motor, and a substantially U-shaped shoulder portion 7' is formed on at least one of the holders.

A U-shaped notch 13 is further formed at the bottom of the claw portion.

The notch 13 is formed to improve the machinability of the mounting claw portion 7' when the motor 11 is caulked and fixed with the mounting claw portion 7' as will be described later.

Bracket? , 71 are formed with bent portions 14 spaced apart by a width slightly larger than the width of the motor 110, and serve to position the motor 11 when it is fixed.

Furthermore, the bracket 7.71 is provided with an abutment surface 15 for the motor 11, separated by a width smaller than the motor 110 width.

The number surface 15 contacts the motor 11 and connects the motors 1 and 10.
It stops rotating.

Next, the mounting state will be explained based on FIGS. 6 and 8.

Groove 8 of bushing 8 fitted into bearing part of motor 11
To attach the bracket 7.71, the bracket 7.71 is inserted into the claw 7', and the upper part of the claw 7' is caulked.

At this time, the cushioning material 10 wrapped around the motor 11 is pressed between the bent portion 14 and the contact surface 15.

For this reason, motor 11 and bracket? , 71 are fixed integrally.

Furthermore, since the notch 13 is formed in the bottom of the claw part 7', the workability when caulking the upper part of the claw part 7' is improved, and the degree of freedom in centering is increased.

As described in detail above, the structure of the motor installation according to the present invention is such that the motor 1 is supported by being clamped on a bracket via bushings attached to the bearings at both ends of the motor, which are wrapped with band-shaped cushioning material. This structure has the following advantages:

■ When assembling the motor 11 and attaching it to the brackets 7 to 71, etc., use the band 5 for metal cursor-shaped mounting.
This eliminates the need for screws 6, etc.

Furthermore, it is possible to reduce the work required to process the screw holes 3' and tighten screws.

■ Since the bushings 8, 9, etc. are interposed between the motor 11 and the brackets 7 to 71, etc., other mechanical parts A
In connection with the shaft 11', centering of the shaft 11' is facilitated, problems such as locking and vibration noise are eliminated, and transmission efficiency is improved.

(2) When the brackets 7 to 71 to which the motor 11 is attached are attached to another location, since the buffer material 10 is interposed, there is no need to insert a new buffer material, and vibration noise etc. can be absorbed.
