Description

리니어가이드{A linear guide}Linear guide {A linear guide}

본 발명은 정밀 연삭 가공된 레일을 따라 운동하는 리니어 가이드에 관한 것으로, 특히 고하중과 고도의 정밀성이 요구되어지는 곳에 적용되어지는 것이다.The present invention relates to a linear guide that moves along a precision ground rail, particularly where high loads and high precision are required.

현재 일반적으로 사용되어지는 리니어 가이드는 R형 트랙롤러 가이드로서 도3에 도시되어 있다 The linear guides currently commonly used are shown in Figure 3 as R-shaped track roller guides.

그 구조로서는 이송수단을 제공하는 캐리지와 캐리지의 하방으로 매달리게 장착되어지는 트랙로울러와 상기 트랙로울러의 말착되어지는 샤후트나 볼이 장착되어진 레일로 이루어지는 것이다.Its structure consists of a carriage providing a conveying means, a track roller mounted to be suspended below the carriage, and a rail on which a shaft or ball attached to the track roller is mounted.

따라서 통상 트랙로울러와 레일은 선접촉된 상태에서 마찰을 최소화 하여 이송토록 하고 있는 것이다.Therefore, the track roller and the rail are normally transported to minimize the friction in the line contact state.

그러나 이러한 선 접촉은 많은 하중이 요구되어질 경우에 또는 정밀이송이 요구되어질 경우에는 이러한 볼이나 샤후트 또는 트랙로울러의 밀착면의 만곡가공이 정밀하게 이루어지지 못할 경우에 또한 반복적인 사용에 의한 마찰열에 의하여 변형이 생길 경우에는 사용자가 원하는 정도로 만족할 만한 효과를 얻지 못한다는 단점이 있는 것이다.However, such a line contact may not be subjected to frictional heat due to repeated use when a large load is required or when a precise feed is required, such that the curved surface of such a ball, shaft or track roller cannot be precisely formed. If the deformation occurs by the user has a disadvantage that the user does not get a satisfactory effect to the extent desired.

특히 이러한 것이 정밀 가공이 요구되어지는 전자 또는 통신 장비등에 적용된다는 점을 감안하면 미세한 변화에 의하여 사용이 불가능하게 된다는 단점이 있는 것이고, 특히 고하중에 적용될 경우에는 이러한 리니어 가이드로서는 사용이 불가능하다는 단점이 발생되는 것이다.In particular, it is disadvantageous in that it is impossible to use due to minute changes in consideration of the fact that this is applied to electronic or communication equipment that requires precise machining, and in particular, when applied to high loads, it is impossible to use such a linear guide. It happens.

따라서 본 발명은 상기한 문제점을 해결하기 위한 것으로, 레일과 트랙로울러가 면접촉을 유도함으로서 고하중에 견딜 수 있고 고도의 정밀성을 갖도록 한 것이다.Therefore, the present invention is to solve the above problems, the rail and the track roller to induce surface contact to withstand high loads and to have a high precision.

이하에서는 첨부 도면을 참조하여 본 발명의 가장 바람직한 일 실시 예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시 예를 나타낸 리니어 가이드의 조립되어진 상태를 도시한 것으로, 이송수단을 갖는 캐리지(10)에 회전가능하도록 결합되는 트랙 로울러(20)가 캐리지의 하방으로 매달린 형태로 장착되어지고, 상기 트랙로울러(20)의 롤러(21)는 V홈(22)의 단면을 갖고, 상기 ∨홈(22)과 밀착되어지도록 레일(40)에는 전방으로 돌출되어지도록 ∧형 돌출부(31)를 갖는 사각샤후트(30)가 레일의 ∨홈(41)에 끼워져 고정되어지는 것이다.1 is a view illustrating an assembled state of a linear guide according to an embodiment of the present invention, in which a track roller 20 coupled to the carriage 10 having a conveying means to be rotatable is mounted in a form suspended from below the carriage. The roller 21 of the track roller 20 has a cross section of the V-groove 22, and the X-shaped protrusion 31 protrudes forward on the rail 40 so as to be in close contact with the groove 22. The square shaft 30 having a) is fitted into the groove 41 of the rail to be fixed.

이때 사각샤후트(30)가 끼워진 상태에서 전방으로의 이탈이 방지되어지도록 레일(40)의 ∨홈(41)은 ∨홈(41)의 전단으로 걸림턱(42)을 형성하는 것이다.At this time, the groove 41 of the rail 40 is formed in the front end of the groove 41 to form a locking step 42 so that the departure to the front in the state in which the rectangular shaft 30 is fitted.

이와 같이 레일(40)에 사각샤후트(30)가 별도로 끼워져 장착되어지는 것은 트랙로울러(20)의 롤러(21)가 이동될 경우에 생기는 마찰열로 인하여 레일(40)의 변형이 발생되어짐을 방지하기 위하여 열처리되어진 사각샤후트(30)를 레일(40)에 장착토록 함으로서 경제성과 사용의 다양성은 물론 편의성을 갖도록 한 것이다.As such, the rectangular shaft 30 is separately fitted to the rail 40 to prevent deformation of the rail 40 due to frictional heat generated when the roller 21 of the track roller 20 is moved. In order to equip the rail 40 with the heat treated square shaft 30 in order to have a variety of economics and use as well as convenience.

따라서 사각샤후트(30)의 ∧형 돌출부(31)와 이와 맞물리는 트랙로울러의 롤러(21)의 ∨형 홈(22)에 의하여 면접촉 되어짐으로 캐리지(10)에 많은 하중이 걸릴 경우에도 정밀하고 고속의 이송이 가능하게 되는 것이다.Therefore, even when a large load is applied to the carriage 10, the contact is brought into surface contact by the X-shaped protrusion 31 of the square shaft 30 and the X-shaped groove 22 of the roller 21 of the track roller engaged therewith. And high speed transfer is possible.

본 발명은 트랙로울러와 레일이 면접촉되어짐으로 정밀이송과 고하중에 적용이 가능하다는 장점이 있는 것이다.The present invention has the advantage that the track roller and the rail is in contact with the surface, it is possible to apply the precision transfer and high load.
