수직형 풍력발전기용 베어링 장치 { bearing equipment for vertical axis wind turbine }Bearing devices for vertical wind turbines {bearing equipment for vertical axis wind turbine}

본 발명은 수직형 풍력발전기에 있어서 회전체의 하중에 의하여 발생되는 베어링의 마모 및 파손 방지와 회전체의 회전력을 이용하여 베어링 또는 회전축에 오일주입을 할 수 있는 수직형 풍력발전기용 베어링 장치에 관한 것이다.The present invention relates to a bearing device for a vertical wind turbine generator capable of injecting oil into a bearing or a rotating shaft by using the rotational force of the rotor and the prevention of wear and breakage of the bearing caused by the load of the rotor in a vertical wind turbine generator. will be.

일반적으로 수직형 풍력발전기는 바람에너지를 운동에너지로 바꾸어 주는 회전체를 회전축에 결합 구성하며, 상기 회전축은 원활한 회전력을 갖기 위해 베어링이 구성된 커버링과 결합 구성하여 이루어진다.In general, the vertical wind turbine is coupled to the rotating shaft for converting the wind energy into kinetic energy on the rotating shaft, the rotating shaft is made by combining with a covering consisting of a bearing to have a smooth rotational force.

상기와 같이 커버링에 구성된 베어링은 회전체의 하중에 의하여 베어링의 마모 및 파손이 발생되며, 베어링의 녹의 방지를 위하여 오일 주입을 하여야 된다.Bearings configured in the covering as described above is caused to wear and damage of the bearing by the load of the rotating body, and oil should be injected to prevent the rust of the bearing.

종래에는 상기 베어링 슬리브 하단에 트러스트 베어링을 구성하여 베어링의 회전력에 도움을 주었으나, 상기와 같은 방법으로는 회전체가 회전 시 발생되는 회전력에 의하여 베어링의 슬리브 하단 부분과 고정되어 있는 트러스트 베어링이 마모되었고, 회전체의 하중에 의하여 베어링의 마모가 진행되어 회전체의 회전력을 저해시키는 문제점은 여전히 발생되었다.Conventionally, a thrust bearing is formed at the bottom of the bearing sleeve to help the rotational force of the bearing. However, the thrust bearing fixed to the lower end of the sleeve of the bearing is worn by the rotational force generated when the rotor is rotated. The wear of the bearing was advanced by the load of the rotating body, and the problem of inhibiting the rotating force of the rotating body still occurred.

또한 상기 베어링은 수직형 풍력발전기를 설치 후에 녹의 방지를 위하여 주입하는 오일 주입의 기간이 짧으면서 베어링에 손으로 직접 주입하여야 하는 문제점이 있었다.In addition, the bearing has a problem in that the oil injection to prevent rust after the installation of the vertical wind power generator has to be injected directly into the bearing by hand.

본 발명은 상기와 같이 수직형 풍력발전기에 구성되어 있는 회전체의 원활한 회전력을 갖도록 하면서, 상기 회전체의 하중에 의하여 베어링의 마모 및 파손을 방지하고, 회전체의 회전력을 이용하여 베어링에 오일 주입의 기간을 연장하는 수직형 풍력발전기용 베어링 장치를 제공하는데 그 목적이 있다.The present invention prevents abrasion and breakage of the bearing by the load of the rotating body while having a smooth rotational force of the rotating body constituted in the vertical wind generator as described above, and injecting oil into the bearing using the rotating force of the rotating body It is an object of the present invention to provide a bearing device for a vertical wind turbine that extends the period of time.

상기와 같이 구성된 본 발명의 수직형 풍력발전기용 베어링 장치(1)의 작용 효과를 살펴보면 다음과 같다.Looking at the effect of the vertical wind generator bearing device (1) of the present invention configured as described above are as follows.

먼저 상기 커버링(20)에 베어링(30)을 삽입 시의 작용효과를 살펴보면, 상기 받침대(21) 위에 베어링(30)을 삽입함으로서 베어링(30)은 커버링(20)의 하단으로 내려가는 것을 방지할 수 있으나, 상기 베어링(30)의 슬리브(32)는 상기 커버링 관통공(25)과 결합 구성되는 회전축(10), 상기 회전축(10)과 결합 구성되는 회전체(11)의 하중에 의하여 하단으로 내려 앉아 베어링(30)이 마모 및 파손이 발생되는데, 상기 "

By inserting the bearing 30 on the pedestal 21, the bearing 30 can be prevented from descending to the lower end of the covering 20. However, the sleeve 32 of the bearing 30 is lowered to the lower end by the load of the rotating shaft 10 is coupled to the covering through hole 25, the rotating body 11 is coupled to the rotating shaft 10 Sit bearings 30 wear and breakage occurs, the "

"The groove 23 may be formed larger or smaller by the radius of the beads 24, but can generally support the bottom of the sleeve 32 of the bearing 30 while the beads 24 can rotate smoothly. It is desirable to be able to.

또한 상기 오일주입 홈(22)에 오일을 주입 시의 작용효과를 살펴보면, 상기 회전체(11)의 가속도가 0인 상태에서 풍속이 높아지면서 점차 가속도가 증가하게 되는데 이때 회전체(11)의 회전 속도에 의해 회전축(10)의 하단부에서는 회전축(10)의 회전 방향과 동일한 방향을 갖는 와류가 형성되고, 형성된 와류는 회전축(10) 하단부와 대항하고 있는 오일주입 홈(22)으로 유입된 후, 선회하면서 오일주입 홈(22)의 중심부로 유입되는데 이때 발생되는 유체압은 크지 않지만 회전축(10)을 부상시키려는 소정의 유체압이 발생하게 되며, 상기 유체압에 의하여 오일주입 홈(22)에 주입하여 놓은 오일이 베어링(30)의 간극(31)으로 흘러 들어가 베어링(30)과 구슬(24)의 녹을 방지하면서 원활한 회전력을 갖도록 하는 효과를 갖으며, 회전체(11)의 가속도가 0인 상태에서는 베어링(30)과 구슬(24)의 겉에 붙은 오일이 오일주입 홈(22)과 "
