Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper actuator, and more particularly, to a damper actuator that realizes a starting torque required for starting the device at a low reduction ratio using a BLDC motor, simplifies a deceleration structure, and improves durability.

Various dampers (airflow control damper, fire damper, relief damper, electric damper) and the like are used for the control of the air flow rate of the duct and the opening and closing of the duct, and each damper is generally driven by a damper actuator.

At this time, since the damper is generally installed at a place where the operator is difficult to enter, the durability of the damper actuator for driving the damper is very important.

However, since a general damper actuator used in the related art uses a general synchronous motor, a deceleration structure for obtaining a force for driving the damper is complicated and many accidents occur due to a complicated structure.

Accordingly, in order to solve the problem of opening and closing the damper when the damper actuator fails, the damper is opened by using the mechanical spring which stores the energy when the damper actuator is driven when the electric energy transmitted from the external synchronous motor is shut off. The problem-solving method is applied to a damper having a purpose opposite to each other, such as a fire damper, which is required to shut off each designated zone when a fire occurs, and an airflow-adjusting damper that must be opened to discharge the smoke I could not.

1, a duct connected to the damper 10 is opened using the motor 20 and a bi-directional damper (not shown) which can close the duct by using the return spring 60, It is undeniable that the device has been developed but can not solve the fundamental durability problem of the damper actuator by utilizing the elasticity of the return spring 60 when the duct is closed.

Accordingly, there is a need for a damper actuator that can simplify the structure of the damper actuator to improve its durability and can be driven in accordance with the purpose of the damper in the event of an emergency.

Hereinafter, the damper actuator according to the present invention will be described with reference to the drawings.

2 to 4, the damper actuator according to the present invention includes a motor assembly 100 that generates power by electric energy input from the outside, a complex gear unit 100 that transmits a force generated by the motor assembly 100, An output unit 300 coupled to the driving and discharging of the damper and rotating the driving shaft of the damper by a force transmitted from the compound gear unit 200 and a motor assembly 100, And an outer housing 400 surrounding the output unit 300.

At this time, the outer housing 400 is divided into an upper housing 410 and a lower housing 420 as shown in FIG. 2, and the housings are vertically assembled to each other. That is, the motor assembly 100, the complex gear unit 200, and the output unit 300 are provided in the housing 400.

Hereinafter, the motor assembly 100, the complex gear unit 200, and the output unit 300 provided in the outer housing 400 will be described.

3 and 4, the damper actuator according to the present invention includes a DC brushless (BLDC) motor 110 in which the motor assembly 100 receives electricity from the outside and rotates, a DC brushless motor And a planetary gear set 120 for reducing the rotational force transmitted from the planetary gear set 120. The compound gear set 200 includes a worm gear 210 for changing the direction of rotation transmitted from the planetary gear set 120, A spur gear 220 that receives a rotational force from the worm gear 210 and rotates the spur gear 230 inserted in the same rotational axis 221 and a section gear 240 that receives rotational force from the spur gear 230, And the output unit 300 is fixed to the rotation shaft of the section gear 240.

3, when the DC brushless motor 110 receives electric energy from the outside and rotates, the rotational force transmitted from the DC brushless motor 110 to the planetary gear set 120 is transmitted to the DC brushless motor 110, Thereby primarily increasing the torque. That is, the rotation speed is reduced and the power density is increased.

The rotational force transmitted from the planetary gear set 120 to the worm gear 210 is converted in the rotational direction through the worm gear 210 and the spur gear 220 so as to be rotated in the same direction as the output unit 300 do. That is, the direction of the rotational force transmitted from the DC brushless motor 110 is converted into the rotational direction of the output unit 300 by using the worm gear 210 and the spur gear 220.

At this time, secondary deceleration may occur according to the gear ratios of the worm gear 210 and the spur gear 220.

4, one end of the spur gear 220 in the longitudinal direction of the rotating shaft 221 is fitted in the first rotating bearing 421 located on the lower side of the inner surface of the lower housing 420, And the other side is engaged with a second rotation bearing 423 coupled to the upper side of the plurality of support rods 422 extending upward from the lower side of the inner surface of the lower housing 420.

That is, the rotary shaft 221 has one end in the longitudinal direction fitted to the first rotary bearing 421, the other longitudinal side of which is fitted in the second rotary bearing 423, Direction.

At this time, the spur gear 220 is fitted on the rotation shaft 221 and receives the rotational force from the worm gear 210. The rotation shaft 221 is rotated by the rotational force of the spur gear 220, Thereby rotating the spur gear 230 fitted in the lower side. Third deceleration is generated according to the number of teeth of the spur gear 220 and the spur gear 230.

5, the spur gear 230 rotates the output unit 300 fixed to the rotary shaft of the fan-shaped section gear 240 by transmitting the rotational force to the section gear 240.

Specifically, the damper actuator according to the present invention is a device for opening and closing a damper provided in a duct. It is sufficient to rotate the drive shaft of the damper to open and close the damper, and rotate the drive shaft of the damper by about 90 degrees for opening and closing the damper. Higher torque is required to open and close.

Therefore, by using the DC brushless motor 110, the torque generated by the motor is improved compared to a general motor, thereby simplifying the deceleration structure of the gear portion 200, The brushless DC motor 110 reduces the torque transmitted from the DC brushless motor 110 through the switch 200 to generate a sufficient torque to rotate the drive shaft of the damper fixed to the output unit 300, The drive shaft of the damper is fixed to the rotary shaft 241 of the section gear 240 having a fan shape in order to prevent the damper from failing.

The drive shaft of the damper may be fixed to the rotation shaft of the section gear 240, but the drive shaft of the damper having various shapes can be easily coupled to the rotation shaft 241 of the section gear 240 through the output unit 300 have.

6, the output unit 300 is divided into an upper flange 310 for fixing the driving shaft of the damper and a lower flange 320 fitted to the rotary shaft of the section gear 240. The upper flange 310 And the lower flange are coupled through the clamping bolts 330. [

4, the lower flange 320 is formed with a first projection 321 having a larger diameter than the rotation axis 241 of the section gear 240 in the circumferential direction on the upper side, The lower surface of the protrusion 321 is seated on the upper surface of the rotary shaft 241 and the lower side of the protrusion 321 is inserted into the rotary shaft 241 of the section gear 240 and the coupling hole 322 in which the driving shaft of the damper is inserted is formed And the inner surface 323 contacting the engagement hole 322 has a tapered structure in which the inner diameter becomes narrower from the upper side to the lower side.

The lower flange 310 has a lower flange 310 fitted to the coupling hole 332 of the lower flange 320 and has a second projection 311 corresponding to the first projection 321 of the lower flange 320, And the first protrusions 321 and the second protrusions 311 are connected to the clamping bolts 330.

That is, the inner surface 323 of the lower flange 320 having a tapered structure when the distance between the first protrusion 321 and the second protrusion 311 is narrowed by using the clamping bolt 330, The second protrusion 311 presses the outer surface of the second protrusion 311 of the upper flange 310 and presses the second protrusion 311 against the drive shaft of the damper so that the diameter of the lower flange 320 is widened, The outer surface pushes the inner surface of the rotary shaft 241 of the section gear 240 and the lower flange 320 is fixed to the section gear 240. [

In addition, the damper actuator according to the present invention is disposed apart from the inner surface of the outer housing 400 facing the upper end of the rotating shaft 221, and the sensor magnet 221-1 is positioned at the upper end of the rotating shaft 221 And a GMR sensor 411 corresponding to the sensor magnet 221-1 is provided on the inner surface of the outer housing 400. The GMR sensor 411 is connected to the output unit 300 can be controlled.

The power generated by the brushless motor 110 to operate the damper is transmitted to the output portion 210 through the planetary gear set 120 and the various gears 210, 220, 230, 240 to improve the rotation torque. 300) and decelerated.

At this time, since the damper actuator according to the present invention decelerates the rotation speed of the brushless motor 110 at a ratio of about 700: 1 and is transmitted to the output unit 300, the rotation speed of the brushless motor 110 having a high rotation speed And it is difficult to accurately measure the rotational speed and displacement of the output unit 300 by measuring the displacement.

Therefore, by measuring the rotation speed and displacement of the rotation shaft 221 through the sensor magnet 221-1 and the GMR sensor 411, the accurate displacement and rotation speed of the output unit 300 can be measured .

The method of measuring the rotational speed and displacement of the rotation shaft 221 through the sensor magnet 221-1 and the GMR sensor 411 is the same as the method using the circular magnet as shown in FIG. As shown in FIG. 8, a rod magnet can be used. When a circular magnet is used, a single GMR sensor 411 is used. When a rod magnet is used, a pair of GMR sensors 411 are used.

When a circular magnet is used as the sensor magnet 221-1, a magnetic field is formed in the vertical direction as shown in FIG. 9, so that the sensor magnet 221-1 and the upper housing 410 It is sufficient to provide the GMR sensor 411 on the inner surface of the rotary shaft 221. However, since the unit price of the circular magnet is high, when the rod magnet is used to lower the manufacturing cost, The pair of GMR sensors 411 are spaced apart from each other around the rotating shaft 221 having the bar magnets.

In addition, the damper actuator of the present invention may further include a battery 500 for driving the motor assembly 100 when the electric energy input from the outside to the motor assembly 100 is interrupted.

In detail, the damper is installed inside a duct which is difficult for an operator to open and close the duct, and the duct should be shut off or opened in an emergency in accordance with the purpose of use.

Accordingly, in the present invention, the battery 500 is provided so as to drive the DC brushless motor 110 in an emergency in which electric energy input from the outside to the DC brushless motor 110 is blocked.

The damper actuator of the present invention is further provided with a control board 600 for controlling the DC brushless motor 110, and it is recommended that the DC brushless motor 110 is controlled by a sensorless method.

At this time, the control board 600 is interlocked with the GMR sensor 411 and the battery 500. In detail, the control board 600 controls the rotation speed and direction of the DC brushless motor 110 using the rotation speed and displacement of the rotation shaft 221 measured by the GMR sensor 411, The DC brushless motor 110 is precisely controlled by a command inputted in advance when the electric power inputted from the outside to the DC brushless motor 110 is interrupted in the control board 600, To open or close the damper.

As a result, the drive shaft of the damper is precisely controlled by using the GMR sensor 411 and the control board 600, and the damper is determined to be opened or closed in an emergency by using the control board 600 and the battery 500.

The damper actuator according to the present invention is characterized in that at least one selected from the spur gear 220, the spur gear 230 and the section gear 240 constituting the multifunctional gear unit 200 is formed of engineering plastic Is recommended.

More specifically, the rotational force transmitted from the DC brushless motor 110 is transmitted through the respective gears, and the rotational speed is reduced and the torque is increased. In the case of the gears 220, 230, Strong friction is generated at the leading teeth and the teeth are worn. Therefore, since lubricating oil is required to reduce the friction generated at the teeth, it is necessary to carry out maintenance work for charging the lubricating oil at all times. The spur gear 220 and the portion of the spur gear 230 and the section gear 240 that are worn are made of engineering plastic which is a polymer compound acting as a lubricant.

The damper actuator according to the present invention is characterized in that a forced rotation axis 111 for driving the DC brushless motor 110 is formed on one side of the DC brushlessless motor 110 and the forced rotation axis 111 is connected to the outer housing 400, It is recommended to protrude to the outside.

More specifically, when the DC brushless motor 110 fails to operate properly due to an error in the control board 600, an operator can directly rotate the forced rotation axis 111 to operate the damper .

The technical idea should not be interpreted as being limited to the above-described embodiment of the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, such modifications and changes are within the scope of protection of the present invention as long as it is obvious to those skilled in the art.
