For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

Hereinafter, a driving apparatus using a single driving source of the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings.

2 is a perspective view illustrating a driving apparatus using a single driving source of the present invention.

Referring to FIG. 2, the driving apparatus using a single driving source of the present invention includes a main body 100 formed in a rectangular plate shape.

The main driving part 10 is coupled to one end of the upper part of the main body 10 and the main driving part 10 is provided with a belt 31 connected to a driving source 30 A first ball screw 11 to which a first pulley 14 is coupled and a first output pulley 13 that outputs power supplied from the input pulley 14 is coupled to the other side, And a first support 12 for supporting the first support 11.

The longitudinal drive unit 20 is coupled to the other side of the main drive unit 10. The longitudinal drive unit 20 includes a first output pulley 13 and a second output pulley 13. The second output pulley 13 receives power generated from the first output pulley 13, A second ball screw 21 coupled to the first ball screw 21 and a second ball screw 21 connected to the second ball screw 21 in the same direction as the first ball screw 11, 22).

The first ball screw 11 and the second ball screw 21 may be either right-handed or left-handed ballscrews, and may be provided with ballscrews that always have the same threading direction.

On the other hand, first and second moving bodies 15 and 25 are coupled to the first and second ball screws 11 and 21, respectively. Elements necessary for machine operation are coupled to the moving bodies 15 and 25 .

On the other hand, the synchronization belt 40 is tightened by twisting the first output pulley 13 and the second output pulley 23 one by one so that both ends have a phase difference of 180 degrees. Therefore, it is possible to drive the ball screws in the same screw direction in opposite directions without using different screw directions for the opposite direction, so that the manufacturing process and manufacturing cost of the driving device can be reduced.

A driving source 30 provided at a rear end of the first supporting body 10 and transmitting power to the main driving unit 10 by a belt 31 is provided. A power generated by the driving means such as a motor (not shown) is transmitted to the belt 31 to the belt 31.

An idler 50 is coupled to the main body 100 in order to minimize the friction between the synchronizing belt 40 and the synchronizing belt 40. Therefore, even if the driving device is driven for a long time, frictional force is minimized between the synchronous belts 40 and the service life is prolonged.

Hereinafter, the operating state of the driving apparatus using the single driving source of the present invention will be described.

The power transmitted by the driving means of the driving source 30 is transmitted to the input pulley 14 through the belt 31 and is rotated. At the same time, a first output pulley (not shown) coupled to the other end of the input pulley 14 13). At this time, the first moving body 15 coupled to the first ball screw 11 also moves forward or backward according to the rotating direction of the driving means.
