* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 지지대 2 : 회전체1: support 2: rotating body
3 : 메탈베어링3: metal bearing
본 고안은 주측대에 의하여 회전되는 공작물을 가공할 때 심압대에서 공작물의 단부중심을 잡아주는 고경센터(Center)에 관한 것이다.The present invention relates to a center of gravity (Center) for holding the end center of the workpiece in the tailstock when machining the workpiece rotated by the main body.
종래에는 제 2도와 같이 지지체 전단에 끝이 뾰족한 회전체를 유착시키되 그 내부의 접촉부분에 볼베이링(Ball Bearing)과 스터스트베어링(Thrust Bearing)을 게재시켜서 된 것이었다.Conventionally, as shown in FIG. 2, a pointed rotary body is adhered to a front end of a support, but a ball bearing and a thrust bearing are placed on a contact portion therein.
그러나, 이와 같은 볼베어링과 스러스트 베어링을 설치한 센터의 경우 볼베어링에 의하여 회전체의 하후징이 커지게 되었으며 일정기간 사용 후에는 한쪽 볼베어링이 편중마모되어 회전체의 중심이 이동됨에 따라 회전속도가 현저히 떨어질 뿐 아니라 그에 의하여 수명이 짧아진다는 문제점이 있었다.However, in the case of the center in which such ball bearing and thrust bearing are installed, the lower hedge of the rotating body is increased by the ball bearing, and after a certain period of use, one side of the ball bearing is eccentrically worn, and the rotational speed of the rotating body is remarkably decreased. In addition, there was a problem that the life is shortened by him.
이외에도, 상기 내부의 접촉부분에 니들베어링을 삽입 개재한 것도 있었으나, 이 역시 니들베어링이 그 지지멤버를 수반하고 있음으로 인해 그 회전체의 하우징크기를 줄이려는 노력에는 그만큼 제한적 요소로 작용하므로 이 또한 불합리한 것이었다.In addition, the needle bearing was inserted into the contact portion of the inner part, but this also acts as a limiting factor in the effort to reduce the housing size of the rotating body because the needle bearing is accompanied by the support member. It was unreasonable.
이외에도 본 고안은 이를 감안하여 회전체의 하우징을 보다 축소하여 소형화를 꾀하고, 베어링의 편중 마모를 제거하여 베어링이 골고루 마모되도록 하여 회전체의 정밀성을 유지하며, 편중마모를 제거하여 회전속도의 고속화를 기함은 물론, 수명을 연장할 수도 있도록 하는 새로운 고정센터를 부여하려는 목적이 있는 것이다.In addition to this, the present invention reduces the housing of the rotating body to further reduce the size of the rotating body, and eliminates the eccentric wear of the bearing so that the bearing is evenly worn to maintain the precision of the rotating body. The purpose is to give new fixed centers that can extend their life as well.
이를 첨부도면에 의거 설명하면 다음과 같다.This will be described based on the accompanying drawings.
회전체(2)와 지지체(1)가 가까워지는 매부 경계부분에 볼베어링(5) 대신 원통형의 단일베인 메탈베어링(3)을 유삽하여서 된다. 또는 메탈베어링(3) 대신 오일레스베어링(Oilless Bearing)을 유삽할 수도 있다.Instead of the ball bearings 5, cylindrical single vane metal bearings 3 are inserted at the boundary portions between the rotor 2 and the support 1 close to each other. Alternatively, an oilless bearing may be inserted instead of the metal bearing 3.
미설명 부호 4는 스러스트베어링이고, 6은 오일공급로이다.Reference numeral 4 is a thrust bearing, and 6 is an oil supply passage.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
본 고안은 통형의 단일체인 메탈베어링(3)이 장치되므로 회전체(2)의 하우징을 보다 소형화 할 수 있으며 베어링의 마모가 베어링 전체에 걸쳐 골고루 마모되므로 회전체(2)의 중심축의 유동이 일어나지 않게되어 회전속도의 고속도유지를 기할 수 있으며 종래와 같은 편중마모에 의한 기기의 손상의 문제점이 없어져 기기의 수명도 보장할 수 있게 된다.The present invention has a cylindrical unitary metal bearing (3) is installed, so that the housing of the rotating body (2) can be further miniaturized, and since the wear of the bearing is evenly worn throughout the bearing, the flow of the central axis of the rotating body (2) does not occur. It is possible to maintain the high speed of the rotational speed, and the problem of damage to the device due to unilateral wear as in the prior art can be eliminated, and the life of the device can be guaranteed.
