Description

Auger motor assembly for combine}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auger motor assembly for a combine, and more particularly, to a new auger motor assembly for a combine, which can minimize the overall size and improve the precision of operation.

Generally, the auger for grazing discharge mounted on a combine, which is a machine for harvesting grain, is configured to perform up or down, or left-turn or priority, by driving an auger motor.

In addition, a conventional auger motor assembly for a combine has a spur gear unit for reducing speed between an input shaft operated by driving of the motor unit and an output shaft connected to the auger.

However, such conventional auger motors have a problem in that the total volume of the auger motors is inevitably large in consideration of the reduction ratio, because the auger motors for such combines are configured to be spaced apart as far as possible in consideration of the gear ratio of the gears between the drive motor and the output shaft.

Particularly, since the auger motor is installed at the operating part, when the size of the auger motor is large, interference with the surrounding water occurs at the operation of the auger, and sufficient space for installing the auger motor having a large peak must be secured. The size of the size was also forced to grow.

Accordingly, in recent years, various researches have been conducted to minimize the size of the auger motor, to secure the mounting space, to prevent occurrence of interference in operation, and to enable more precise operation control .

The reducer housing unit 100 includes a motor shaft 211 and an output shaft 300 So as to reduce the size of the reducer housing 100, thereby reducing the overall size of the auger motor assembly for the combine.

This will be explained in more detail for each configuration.

First, the speed reducer housing 100 is a portion in which a reduction gear unit (not shown) for reducing the number of revolutions of the driving motor and driving the output shaft is built therein. The motor housing 200 has a motor housing 200, And is coupled to the rear of the reducer housing 100, and the drive motor 210 is embedded.

A front through hole 110 through which the output shaft 300 is inserted is formed on the front surface of the reducer housing 100 and a motor shaft 211 of the driving motor 210 is mounted on the rear surface of the reducer housing 100 A through-hole 120 is formed.

Next, the output shaft 300 is connected to a combine auger (not shown) to operate the auger.

The rear end of the output shaft 300 passes through the front through hole 110 of the reducer housing 100 and rotates on the rear surface of the reducer housing 100. [ Lt; / RTI >

Next, the driving motor 210 is a portion that provides a driving force for rotating the output shaft 300.

The driving motor 210 includes a motor shaft 211 fixed to the motor housing 200 and passing through a rear through hole 120 of the reducer housing 100 and having a forward end located inside the reducer housing 100, ).

In addition, a power transmission container 212 is formed at the front end of the motor shaft 211, which is located in the reduction gear housing 100.

Next, the reduction gear unit (not shown) drives the output shaft 300 by reducing the rotational speed of the driving motor 210. [

The reduction gear unit may include a sun gear 510, ring gears 520 and 530 and a plurality of planetary gears 540 so that the output shaft 300 and the motor shaft 211 are maximally adjacent to each other. While the rotation speed provided through the motor shaft 211 is transmitted to the output shaft 300 in a state of being decelerated as much as possible.

The sun gear 510 is rotatably mounted on a circumferential surface of a portion of the output shaft 300 that is positioned within the reduction gear housing 100 and engaged with the power transmission container 212 of the motor shaft 211, . 4) is provided between the sun gear 510 and the output shaft 300 and the sun gear 510 is coupled to the output shaft 300 in a state of being coupled to the bush 550. [ 300). ≪ / RTI >

In particular, the sun gear 510 includes a first gear portion 511 which is engaged with the power transmission container 212 of the motor shaft 211 to form a rear end portion, and a first gear portion 511, And the first gear portion 511 of the sun gear 510 and the power transmission container 212 of the motor shaft 211 are formed of helical gears.

In addition, the second gear portion 512 constituting the sun gear 510 is formed as a planar gear, and is configured to be engaged with each planetary gear 540 to be described later.

The ring gears 520 and 530 are parts that rotate the output shaft 300 while being rotated by receiving the driving force provided to the sun gear 510.

The ring gears 520 and 530 are installed so as to surround the front end side of the sun gear 510 and rotate in the reducer housing 100 by being engaged with the planetary gears 540. At the front end of the ring gears 520 and 530, An output side ring gear 520 having a coupling end 521 coupled with a spline or a gear so as to transmit power and an output side ring gear 520 installed to surround the rear end side of the sun gear 510, And a fixed side ring gear 530 that is installed in a fixed state and guides each planetary gear 540 to pivot about the sun gear 510 by engaging with the respective planetary gears 540.

The planetary gears 540 transmit the rotational force of the sun gear 510 to the ring gears 520 and 530.

Each of these planetary gears 540 is disposed between the front end circumferential surface of the sun gear 510 and the inner circumferential surface of the ring gears 520 and 530.

Next, the sensing unit 400 is a part for determining the rotation angle of the auger by checking the rotation speed of the output shaft 300.

In the embodiment of the present invention, the sensing unit 400 is connected directly to the output shaft 300 so that the number of revolutions of the output shaft 300 can be checked.

That is, when the rotation angle of the auger is measured by measuring the number of revolutions with respect to the motor shaft 211 or other rotating parts other than the output shaft 300, accurate determination can not be performed due to the high rotation speed. The rotation angle of the auger is estimated by measuring the number of revolutions of the output shaft 300 that is substantially coupled to the auger while the rotation speed is slowest.

The sensing unit 400 includes a sensing main gear 410 fixedly mounted on a rear end portion of the output shaft 300 and a sensing main gear 410 disposed on the motor shaft 211 so as to freely rotate, A position sensing sensor 430 for sensing the rotation angle of the auger while being positioned in a lower space on the front side in the reduction gear housing 100 for sensing, And a plurality of connecting gears 440 connecting the driven gear 420 and the positioning sensor 430 to each other.

The reason why the position sensor 430 is located in the front lower space of the reducer housing 100 is that the position of the output shaft 300 is smaller than the position of the motor shaft 211 in the reducer housing 10 As shown in FIG. That is, since the output shaft 300 is located on the upper side of the motor shaft 211, the reduction gear unit is also positioned on the upper side in the reduction gear housing 100, so that the reduction gear housing 100, The size of the reducer housing 100 can be minimized by providing the position sensor 430 in the front lower space of the reducer housing 100.

The reason why the sensing main gear 410 is directly coupled to the output shaft 300 as described above is that the rotation speed of the output shaft 300 (about 20 to 25 RPM) (About 1/9 to 1/10 of the speed) by the sensing driven gear 420 and the respective connecting gears 440 based on the rotation speed of the gears So that the rotation number of the output shaft 300 can be detected more accurately by shifting the rotation speed of the position confirmation sensor 430 to the most accurate reading speed.

Hereinafter, the operation of the auger motor assembly for a combine according to the embodiment of the present invention will be described in more detail with reference to FIGS. 4 to 6. FIG.

First, when the operation control of the auger according to the user's needs is performed, the drive motor 210 is driven and the motor shaft 211 is rotated.

When the rotation of the motor shaft 211 is performed, the first gear portion 511 of the sun gear 510 engaged with the power transmission container 212 of the motor shaft 211 is rotated together, ) Driving force is provided to the sun gear 510 through the power transmission container 212 and a primary deceleration is performed in the power transmission process.

Since the first gear portion 511 and the power transmission container 212 are formed of helical gears, the power transmission between the first gear portion 511 and the power transmission container 212 can be accurately and stably performed, and the sun gear 510 can be transmitted to the bush 550 The rotation of the output shaft 300 due to the sun gear 510 is not performed even if the sun gear 510 is rotated.

The rotation process of the sun gear 510 according to the driving of the driving motor 210 is as shown in FIG.

When the sun gear 510 is rotated according to the above procedure, the respective planetary gears 540 engaged with the second gear portion 512 of the sun gear 510 are rotated to thereby perform secondary deceleration, The output side ring gear 520 meshed with the output side ring gear 520 is also rotated by the rotation of the gear 540, and a third deceleration is performed in the process.

When the output-side ring gear 520 is rotated as described above, the output shaft 300 coupled to the output-side ring gear 520 is also rotated to perform the auger operation. This is as shown in FIG. 5 attached hereto.

Meanwhile, when the output shaft 300 is rotated by the above-described operations, the sensing driven gear 410 fixed to the rear end portion of the output shaft 300 is rotated to rotate the sensing driven gear 420 .

In addition, the position determining sensor 430 can accurately check the rotational speed of the output shaft 300 through the connecting gear 440 rotated by engaging with the sensing driven gear 420, The angle of rotation of the auger is accurately determined based on the number of revolutions of the auger. This is as shown in FIG. 6 attached hereto.

That is, the determination of the rotation angle of the auger is performed based on the rotation of the output shaft 300 whose rotation speed is slower than that of other configurations, so that the positioning sensor 430 can accurately determine the rotation angle of the auger .

Then, the information on the confirmed rotation angle of the auger is used for the drive control of the drive motor 210 as described above.

For example, when the rotation angle of the auger reaches the set angle, the driving motor 210 is controlled to continuously drive until the rotation angle of the auger reaches the set angle. So that the driving is stopped.

As a result, the auger motor assembly for a combine according to the present invention can reduce the rotation speed of the motor shaft 211 driven by the driving motor 210 and the rotation speed of the output shaft 300, The distance between the motor shaft 211 and the motor shaft 211 is minimized, thereby minimizing the overall size of the product.

In addition, since the auger motor assembly for a combine of the present invention is configured so that the confirmation of the rotation angle of the auger can be known through the rotation speed of the output shaft 300, the rotation angle of the auger can be more accurately grasped, The operation control for the rotation can be performed more precisely.

In addition, the auger motor assembly for a combine of the present invention can minimize the size increase of the reducer housing by configuring the position sensor 430 of the sensing unit 400 to be located in the lower space of the reducer housing 100.
