Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a motor support device for a two-tub washing machine, etc. used in general households.

Conventional Structure and Problems Conventionally, this type of motor installation has been carried out by providing a long hole 2 for adjusting the distance between the shafts in the motor support stand 1, and attaching a buffer rubber 3 and a motor flange 4, as shown in Fig. 1. , a cushioning rubber 5, and a washer 6 were stacked in this order and attached to the motor support 1 using a stepped bolt 7 and a seated nut 8.

However, this configuration has a problem in that when a load in the directions of arrows A and B, which is the longitudinal direction of the elongated hole 2, is applied to the motor flange 4, the motor flange 4 moves in the directions of arrows A and B.
To this end, the movement of the motor flange 4 has been prevented by increasing the clamping force on the motor support base 1 and increasing the contact area between the motor support base 1 and the buffer rubber 3. This means that the cushioning rubber 3 and the cushioning rubber 5 are strongly compressed, which weakens the cushioning force of the rubber and causes a problem of increased vibration and noise. Also,
In order to increase the contact area between the buffer rubber 3 and the motor support base 1, the buffer rubber 3 must be made larger, which increases costs and is not a good measure.

Purpose of the invention The purpose of the invention is to solve these conventional problems and provide a motor support device that is inexpensive, generates little vibration and noise, allows easy adjustment of the distance between the shafts, and does not cause the motor to move due to impact. That is.

Structure of the invention In order to achieve the above-mentioned object, the present invention consists of a buffer rubber having a cylindrical large diameter part and a small diameter part, a cylindrical rib is provided in the large diameter part, and a claw part is provided in the large diameter part of the buffer rubber. The motor support device has a structure in which a washer is attached and a recess is provided in the motor support base in which the claw of the washer engages, and when the motor tries to move due to impact force, the claw hits the wall of the recess and moves. This is to prevent

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, 9 is a motor mounted on a motor support stand 10 with three-point support, 11 is a motor pulley having a fan 12, and rotation is transmitted to an impeller pulley 14 via a V-belt 13. , and the pulsator 15 is rotated. 16 is a tank.
The motor 9 has a cushioning rubber 1 on the motor support stand 10.
7, and the motor 9 is configured so that the center distance between the motor pulley 11 and the impeller pulley 14 can be adjusted by rotating around point O in FIG. There are long holes 1 in two of the three locations on the motor support stand 10.
8, and recesses 19 are installed on both sides of one elongated hole 18 at equal angles with the O point as the center. The anti-movement washer 20 has a claw portion 21 that engages with the recess 19, and has a large diameter portion 17-a that holds the motor 9 on the upper surface and a small diameter portion that deforms and holds the motor 9 when the bolt 22 and seated nut 23 are tightened. 17
-b and the large diameter portion 17 of the buffer rubber 17
-a is installed so as to come into contact with the lower end surface of the cylindrical rib 17-c inside the cylindrical rib 17-c. 24 is buffer rubber 17
Press the upper end of the small diameter part 17-b of the small diameter part 17-b.
It is a washer that transforms the

To explain the operation in the above configuration, when attaching the motor 9 to the motor support stand 10, the claw portion 2 of the anti-movement washer 20 installed in the buffer rubber 17
1 is engaged with and attached to the recess on the motor support base 10, movement of the elongated hole 18 in the longitudinal direction can be reliably prevented by the engagement of the claw portion 21 and the recess 19.

On the other hand, the tightening force in the vertical direction is sufficient to prevent the claw portion 21 from coming out of the recess 19, and the motor 9 is held softly by the buffer rubber 17, so that vibrations of the motor 9 are suppressed by the motor support. It also has the effect that it is less likely to be transmitted to the stand 10, and vibration noise of the main body is also reduced.

In the above embodiment, the anti-movement washer is engaged with the recess from above the underframe, but it may also be engaged with the recess from below the underframe. Any configuration is sufficient as long as it engages with the recessed portion of the recess.

Effects of the Invention As is clear from the above embodiments, the motor support device of the present invention has a modified cushioning rubber and a washer having a claw portion therein, so that the washer and the recessed portion on the motor support base are engaged with each other. This makes it possible to prevent movement of the motor due to impact without increasing the tightening force.
