Description

볼나사용 함유부재 조립체Ball Screw Containing Member Assembly
본 발명은 볼나사용 함유부재 조립체에 관한 것으로, 보다 상세하게는 아치형커버와 함유부재(윤활유를 함유한 부재)가 일체형 윤활패키지로 구성되어 볼나사의 나사홈 개수, 윤활유 공급량을 포함하는 현장상황에 따라 사용자 조합에 의해 신속 간편하게 구조변경이 가능하도록 하는 볼나사용 함유부재 조립체에 관한 것이다.The present invention relates to a ball screw containing member assembly, and more particularly, to an on-site situation in which the arcuate cover and the containing member (lubricating oil containing member) are composed of an integral lubricating package including the number of screw grooves of the ball screw and the amount of lubricating oil supplied. Accordingly, the present invention relates to a ball screw-containing member assembly which enables quick and simple structural change by a user combination.
볼나사는, 1열 또는 복열의 나사홈이 형성되면서 구동부에 의해 회전하는 나사축과, 나사축을 타고 이송되는 이송너트와, 이송너트 내부에서 순환되도록 설치되어 나사홈을 타고 구름운동하는 복수의 전동체로 구성되고, 이때 나사홈에는 전동체와의 구름운동에 따른 마모, 손상을 방지하기 위해 작업자에 의존하여 주기적으로 윤활유를 도포하고 있지만, 윤활유 도포량 및 시기를 정확하게 준수하지 못할 경우 볼나사 수명 단축과 직결되는 실정이다.The ball screw has a screw shaft which is formed by a single row or a double row of screw grooves, a transfer nut conveyed through the screw shaft, and a plurality of electric motors installed to circulate inside the transfer nut and rolling through the screw grooves. In this case, the screw groove is periodically lubricated depending on the operator to prevent wear and damage caused by rolling motion with the rolling elements. It is directly connected.
이에 종래에 개시된 볼나사용 윤활기술을 살펴보면, 대한민국 등록특허공보 제10-1395128호에서, 장축에 설치된 이동체 및 윤활유닛을 포함하고, 윤활유닛에 오일 탱크를 구비하고, 센서에 의해 이동체의 작동을 감지하면 제어기에서 모터를 구동시켜 오일 탱크에 저장된 윤활제를 장축 표면으로 수송하도록 하는 자동윤활 기술이 선등록된 바 있다.Looking at the conventional ball screw lubrication technology disclosed in the Republic of Korea Patent Publication No. 10-1395128, comprising a moving body and a lubrication unit installed on the long axis, the lubrication unit is provided with an oil tank, the sensor detects the operation of the moving body Auto lubrication technology has been pre-registered to drive the motor in the controller to transport lubricant stored in the oil tank to the long axis surface.
그러나, 상기 종래기술은, 센서, 모터, 제어기를 포함하는 구성부품들이 윤활유닛 내부의 협소한 공간에 설치되므로, 구조가 복잡하고 잔고장이 많으며, 고가이면서, 특히 별도의 전원을 필요로 하므로 유지관리가 번거롭고 추가적인 비용이 지속적으로 발생되는 문제점이 따랐다.However, since the components including the sensor, the motor, and the controller are installed in a narrow space inside the lubrication unit, the structure is complicated, has a lot of trouble, and is expensive, in particular, because a separate power source is required for maintenance. This is cumbersome and adds to the ongoing costs.
뿐만 아니라, 시중에 유통되는 볼나사 제품들은 나사홈 개수에 따라 1줄 타입 또는 복수 줄 타입으로 구성되면서 나사축의 피치 및 직경사이즈 별로 다양한 모델들로 구분되므로, 종래기술의 경우 이러한 각각의 모델 별로 전용의 윤활유닛이 다양하게 준비되어야 함에 따라, 재고관리 비용이 상승하고, 나아가 나사홈 개수, 설치공간 및 윤활유 공급량을 포함하는 현장상황에 유연하게 대응할 수 있는 사용자 조합에 의한 구조변경이 불가능한 폐단이 따랐다.In addition, commercially available ball screw products are divided into various models according to the pitch and diameter size of the screw shaft while being configured in a single row type or a plurality of row types according to the number of screw grooves. As the lubrication unit must be prepared in various ways, the cost of inventory management increases, and furthermore, it is impossible to change the structure by the user combination that can flexibly respond to the on-site situation including the number of screw grooves, the installation space, and the amount of lubricant supply. .
한편, 볼나사 단면에서 볼때 분할되지 않는 일체형 윤활씰을 설치할 경우, 나사골에 윤활부재가 너트와 중심을 정확하게 맞추어 장착되지 않을 경우 윤활부재가 나사축과 접촉시 편심되는 결과를 초래한다. 그 결과 편심된 방향의 윤활부재는 나사축의 나사골과 정상적인 접촉을 하지 못하여 윤활작용을 하지 못해 윤활 불량을 초래할 뿐만 아니라, 편심에 의해 과다한 접촉을 일으켜 작동 토오크의 증대화를 초래하는 원인이 되었다.On the other hand, when installing an integral lubrication seal that is not divided when viewed from the cross section of the ball screw, if the lubrication member is not fitted with the nut in the center of the screw bone, the lubrication member is eccentric when contacting the screw shaft. As a result, the lubricating member in the eccentric direction does not come into normal contact with the screw bones of the screw shaft, thereby not lubricating, resulting in poor lubrication, and causing excessive contact due to eccentricity, which causes an increase in operating torque.
이에 따라 본 발명은 상기한 문제점을 해결하기 위해 착안된 것으로서, 아치형커버와 나사축에 윤활유를 공급하는 함유부재가 일체형 윤활패키지로 구성되어 볼나사의 나사홈 개수, 윤활유 공급량을 포함하는 현장상황에 따라 사용자 조합에 의해 신속 간편하게 구조변경이 가능하도록 하는 볼나사용 함유부재 조립체를 제공하는 것에 그 목적이 있다.Accordingly, the present invention has been conceived to solve the above problems, the containing member for supplying lubricating oil to the arcuate cover and the screw shaft is composed of an integral lubrication package in the field situation, including the number of screw grooves of the ball screw, the amount of lubricating oil supply Accordingly, an object of the present invention is to provide a ball screw-containing member assembly which enables quick and simple structural change by a user combination.
