Adjustable motor bed device for blower and blower including the same {ADJUSTABLE MOTOR BED DEVICE FOR BLOWER AND BLOWER INCLUDING THE SAME}

The present invention relates to an adjustable motor bed device for a blower and a blower including the same, and more particularly, it is possible to easily and safely adjust and replace the tension of the fan belt of the blower, and always keep the tension of the fan belt constant. It relates to an adjustable motor bed device for a blower and a blower including the same, which can prevent vibration of the fan belt, prevent transmission of motor vibration, reduce heat generation and increase the lifespan of the fan belt.

In general, a motor is a device that uses electric energy to create mechanical movement. When a permanent magnet is placed inside the motor to create a magnetic field and current flows through a wire connected to the shaft, the shaft rotates by electromagnetic force. As a result, it is used as a simple way to connect various types of belts or gears that transmit and transform rotational force to the motor shaft, so it is applied to almost all mechanical devices and has various sizes and outputs.

The fan of the blower using the driving motor as a driving source implements power transmission through a belt coupled to each pulley.

In this way, the belt connecting the pulley of the drive motor and the pulley of the blower fan must always maintain an appropriate tension in order to effectively transmit the driving force.

As shown in FIGS. 1 and 2, the motor bed according to the prior art has a drive motor 20 installed on one side so as to rotate and drive the fan of the blower 10, and the blower 10 is of the drive motor 20 Rotation is driven by receiving rotational driving force through the belt 30 .

Here, the drive motor 20 is fixedly mounted on the bed 41 through motor fixing bolts 42, and the bed 41 is fixed to the support frame 50 to which the blower is fixed.

In this motor bed structure, during maintenance, such as when the belt slips, shakes, or breaks away, or when replacing the driving motor, manually loosen the motor fixing bolt 42 using a tool and insert the tool into the pulley and the belt to remove the belt. After removing the belt and replacing the belt, before completely fixing the drive motor, pull the motor using the motor fixing bolts that are horizontal around the drive motor and completely fix it.

However, in the prior art, since the operator manually did it, there was a concern that an accident of getting his or her hand caught would occur.

In addition, due to the vibration of the drive motor and the shaking of the belt, the belt is stretched due to the overload applied to the belt and cannot maintain a constant tension. There was a concern that a safety accident might occur because it had to be done.
