본 고안은 스크류잭에 관한 것으로, 더욱 상세하게는 단순한 구조의 개선에 의해 제조가 쉽고 가격이 저렴하면서도 여타의 스크류잭과도 비교될만한 성능을 겸비한 스크류잭에 관한 것이다.The present invention relates to a screw jack, and more particularly, to a screw jack having a performance that is easy to manufacture and inexpensive by a simple structure improvement and comparable to other screw jacks.

일반적으로 스크류잭은 구동모터의 회전운동을 수크류축을 이용하여 직선운 동으로 바꾸는 장치로써 나사산에 의해 큰 토크를 얻을 수 있으므로 다양한 분야에서 활용되고 있다.In general, the screw jack is a device that converts the rotational motion of the drive motor to linear movement using the sock shaft, so that a large torque can be obtained by the screw thread has been used in various fields.

일예로, 추적식 태양광 발전 시스템은, 일출에서 일몰까지의 태양의 위치를 추적하기 위한 방위각 즉 수평각의 조절과 태양의 고도 변화를 추적하기 위한 고도각 조절을 위해 각각 두 개의 구동부를 구비하게 되며, 이 구동부는 주로 스크류잭을 이용하게 되었다.For example, the tracked photovoltaic system includes two driving units for adjusting the azimuth angle, that is, the horizontal angle, to adjust the position of the sun from sunrise to sunset, and the altitude angle adjustment for tracking the change in the altitude of the sun. In this case, the driving unit mainly uses screw jacks.

이러한 추적식 태양광 발전 시스템은 신 재생에너지 보급이라는 국가 시책에 따라 사업규모가 커짐에 따라 많은 업체가 관심을 가지게 되고 또 서로 경쟁하게 되었으며, 그에 따라 제품의 가격 경쟁 우위를 점하기 위한 노력들을 하고 있다.As the scale of business grows in accordance with the national policy of renewable energy, many of these companies become interested and compete with each other, thus making efforts to obtain competitive price of products. have.

종래의 스크류잭은 Conventional screw jack

실린더와 그 내부를 출몰하는 스크류축 및 상기 스크류축을 출몰구동하기 위한 구동수단으로 구성된다.And a screw shaft for projecting the cylinder and its interior, and driving means for projecting and driving the screw shaft.

또한, 상기 구동수단은 실린더의 일측에 고정설치된 구동모터와, 상기 구동모터의 동력을 스크류잭에 전달하기 위한 워엄기어 및 내경에 스크류축과 대응되는 암나사부를 구비한 구동기어로 구성된다. 특히 상기 구동기어는 실린더의 입구부에 회전가능하면서 견고한 결합상태를 유지하기 위한 베어링을 필요로 한다.In addition, the drive means is composed of a drive motor fixed to one side of the cylinder, a worm gear for transmitting the power of the drive motor to the screw jack and a drive gear having a female screw portion corresponding to the screw shaft in the inner diameter. In particular, the drive gear needs a bearing that is rotatable at the inlet of the cylinder and maintains a securely coupled state.

이러한 구조에 의해 구동모터가 회전되면, 상기 워엄에 의해 실린더 입구부에 설치된 구동기어가 정회전 또는 역회전하여 스크류축을 전진 또는 후진시키는 구조를 갖게 되는 것이다.When the drive motor is rotated by this structure, the drive gear installed in the cylinder inlet portion by the worm has a structure for forward or reverse rotation of the screw shaft.

그런데 종래의 스크류잭은 상술한 바와 같이 워엄에 의해 내경에 암나사를 갖춘 구동기어가 회전하여 내부에 스크류축을 출몰시키도록 된 구조이므로 고가의 워엄기어와, 또한 구동기어를 실린더의 입구부에 회전가능하면서도 견고한 결합상태를 이루기 위한 고가의 베어링을 설치해야 하기 때문에 고가의 부품 수 증가에 따른 제품 코스트가 높아지는 단점이 있었다.However, since the conventional screw jack has a structure in which a drive gear having a female thread in its inner diameter is rotated by the worm to blast the screw shaft therein, the expensive worm gear and also the drive gear can be rotated at the inlet of the cylinder. In addition, since expensive bearings have to be installed to achieve a firm coupling state, the product cost increases due to the increase in the number of expensive components.

상기 단점을 해소하기 위한 본 고안의 목적은, The purpose of the present invention for solving the above disadvantages,

스크류잭의 동력전달 구조에 있어서, 스크류잭을 출몰시키는 링기어를 구동모터가 직접적으로 회전시키는 구조로 구성함으로써 부품 수를 줄이고 또 제조가 신속 간편하며, 제품의 코스트를 낮출 수 있는 스크류잭을 전달하는데 그 목적이 있다.In the power transmission structure of the screw jack, the ring gear that drives the screw jacks is directly rotated by the driving motor, so that the number of parts is reduced, manufacturing is quick and simple, and the cost of the product is reduced. Its purpose is to.

사기 목적을 달성하기 위한 본 고안은,The present invention to achieve the purpose of fraud,

상기 실린더의 외부에서 실린더가 축회전 가능하도록 지지하는 하우징과,A housing for supporting the cylinder to be rotatable outside of the cylinder;

외부에 상기 나선홈과 대응되는 수나사산을 가져 상기 실린더의 내부에 결합되어 상기 실린더 및 구동기어의 정역회전에 의해 출몰작동하여 구동력을 전달하는 스크류축과,A screw shaft having a male screw thread corresponding to the spiral groove on the outside, which is coupled to the inside of the cylinder and is driven by the forward and reverse rotation of the cylinder and the drive gear to transmit driving force;

상기 실린더의 후미부에 위치하여 상기 실린더를 회전시키는 구동모터로 구성되는 것을 특징으로 한다.Located in the rear portion of the cylinder is characterized in that consisting of a drive motor for rotating the cylinder.

상기 목적을 달성하기 위한 본 고안은, The present invention for achieving the above object,

이하, 본 고안의 구성을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings the configuration of the subject innovation will be described in detail.

도 1은 본 고안에 따른 스크류잭의 구조를 나타낸 단면도이고, 도 2는 본 고안의 스크류잭(10)이 설치된 상태도이다.1 is a cross-sectional view showing the structure of a screw jack according to the present invention, Figure 2 is a state diagram installed screw jack 10 of the present invention.

본 발명의 스크류잭(10)의 구성은, 입구부에 상기 내주면에 암나사산을 가지는 링기어가 고정 설치된 실린더(11)와, 실린더(11)의 외부에서 실린더(11)가 축회전 가능하도록 양단을 베어링으로 지지하는 하우징(13)과, 외부에 상기 나선홈과 대응되는 수나사산을 가져 상기 실린더(11)의 내부에 결합되어 상기 실린더(11)의 정역회전에 의해 출몰작동하는 스크류축(14)과, 상기 실린더(11)의 후미부에 위치하여 상기 실린더(11)를 회전시키는 구동모터(M)로 구성된다.The configuration of the screw jack 10 of the present invention includes a cylinder 11 in which a ring gear having a female thread is fixed to the inner circumferential surface at an inlet portion thereof, and both ends thereof so that the cylinder 11 can be axially rotated from the outside of the cylinder 11. Screw shaft 14 having a male screw thread corresponding to the helical groove on the outside and a housing 13 supporting the bearing as a bearing, which is coupled to the inside of the cylinder 11 and is sunk by the reverse rotation of the cylinder 11. ) And a driving motor (M) for rotating the cylinder (11) located at the rear end of the cylinder (11).

또한, 스크류축(14)의 단부에는 브래킷(15)이 구비되어 구동목적물 즉, 도 2에 도시된 바와 같이 추적식 태양광 발전기의 수평축(S)이나 날개축(S')의 회동을 위한 아암(A)에 핀 결합된다.In addition, the end of the screw shaft 14 is provided with a bracket (15) to drive the object, that is, the arm for the rotation of the horizontal axis (S) or wing shaft (S ') of the tracked photovoltaic generator as shown in FIG. It is pinned to (A).

상기 실린더(11)의 내부에는 스크류축(14)의 원활한 출몰과 부식을 방지하기 위한 윤활유(그리스)가 충진되어 있다.The cylinder 11 is filled with lubricating oil (grease) to prevent the smooth appearance and corrosion of the screw shaft 14.

또한, 상기 구동모터(M)의 축과 상기 실린더(11) 후미부 축(17) 사이에 연결장치가(16)(커플러) 설치되어 동력이 전달된다.In addition, a coupling device 16 (coupler) is installed between the shaft of the drive motor M and the rear shaft 17 of the cylinder 11 to transmit power.

즉, 상기 연결장치(16)는 구동모터(M)의 구동축과 상기 실린더(11) 후미부 축(17)을 연결할 때 축의 중심이 일치하지 않아 회전시 비틀림이나 저항이 발생될 때 그 오차를 흡수하면서 회전력을 원활히 전달하는 유연함을 제공하는 기능을 수행하게 된다.That is, the connecting device 16 absorbs the error when the torsion or resistance occurs during rotation because the center of the shaft does not coincide with each other when the driving shaft of the driving motor M and the rear shaft 17 of the cylinder 11 are connected. While providing the flexibility to transmit the rotational force smoothly.

따라서 구동모터(M)와 실린더(11) 후미부 축(17) 사이에 발생되는 오차를 연결장치(16)가 흡수하여 동력을 전달하기 때문에 원활한 동력전달이 이루어지게 된다.Therefore, since the connection device 16 absorbs the error generated between the driving motor M and the rear end shaft 17 of the cylinder 11 to transmit power, smooth power transmission is achieved.

이때 구동모터(M)와 하우징(13)은, 구동모터(M)에 설치된 플랜지(18)와 하우징(13)의 후미부에 설치된 플랜지(18') 사이를 복수개의 지지대(19)로 연결 고정하여 결합된다.At this time, the driving motor M and the housing 13 are connected and fixed by a plurality of supports 19 between the flange 18 provided at the driving motor M and the flange 18 'provided at the rear end of the housing 13. Are combined.

또한, 상기 하우징(13)의 측부에는 브래킷(15')이 설치되어 고정지지물 즉, 도 2에 도시된 바와 같이 기둥(P))에 회동가능하게 설치된다.In addition, a bracket 15 ′ is installed at the side of the housing 13 so as to be rotatably installed on the fixed support, that is, the pillar P as shown in FIG. 2.

참조부호 C는 연결장치(16) 즉, 커플러의 외부를 둘러싸 보호하는 케이스이다.Reference numeral C denotes a case which surrounds and protects the outside of the connecting device 16, ie, the coupler.

이러한 구성으로 되어 있는 본 고안 스크류잭(10)의 작동을 살펴본다.Looking at the operation of the screw jack 10 of the present invention having such a configuration.

구동모터(M)가 작동하게 되면 연결장치(16)를 통해 실린더(11)가 하우징(13)에 지지되어 회전하게 되고, 그 입구부에 설치된 구동기어(12)가 함께 회전하게 된다. 이 작동에 의해 스크류축(14)이 전방으로 전진하거나 또는 후진하여 구동목적물이 작동하게 되는 것이다.When the driving motor M is operated, the cylinder 11 is supported and rotated by the connecting device 16, and the driving gear 12 installed at the inlet portion rotates together. By this operation, the screw shaft 14 is moved forward or backward and the driving object is operated.

도 2는 추적식 태양광 발전시스템에 적용된 본 고안 스크류잭(10)을 도시한 것으로, 상기 하우징(13)에 구비된 브래킷(15')이 기둥(P)에 회동가능하게 설치되어 있으며, 상기 스크류축(14) 선단의 브래킷(15)이 주축(S) 또는 날개축(S')을 회 전시키기 위한 아암(A)에 핀결합되어 상기 스크류축(14)의 출몰에 의해 상기 주축(S) 또는 날개축(S')이 회동 되도록 되어 있다.Figure 2 shows the present invention screw jack 10 applied to the tracking photovoltaic power generation system, the bracket (15 ') provided in the housing 13 is rotatably installed on the pillar (P), The bracket 15 at the tip of the screw shaft 14 is pin-coupled to the arm A for rotating the spindle shaft S or the blade shaft S 'so that the spindle shaft S is caused by the appearance of the screw shaft 14. ) Or the wing shaft S 'is rotated.

이상에서 살펴본 바와 같이 본 고안 스크류잭은 구동모터가 직접적으로 구동기어를 구동시켜 스크류축을 출몰시키는 구조이기 때문에 종래와 같이 워엄이나 구동기어를 회전시키면서 실린더에 결합상태를 유지하기 위한 고가의 베어링 등이 필요 없게 되므로 결국 고가의 부품수가 줄어들게 되는 효과를 가지게 되며, 그에 따른 제품 코스트가 절감되는 장점이 있다.As described above, the screw jack of the present invention has a structure in which the drive motor directly drives the drive gear to engrave the screw shaft, so that an expensive bearing for maintaining the state of engagement with the cylinder while rotating the worm or the drive gear as in the related art Since there is no need to have the effect of reducing the number of expensive parts eventually, there is an advantage that the product cost is reduced accordingly.
