본 발명은 유니버설 조인트에 관련된 기술로서, 보다 상세하게는, 유니버설 조인트를 구성하는 두 개의 요크와 스파이더 사이에 개재되어 조인트의 회전 운동을 지지하는 니들 베어링에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a universal joint, and more particularly, to a needle bearing interposed between two yokes and a spider constituting the universal joint to support rotational movement of the joint.

주로 자동차의 스티어링 칼럼과 스티어링 기어가 서로 연결되는 부위 등에는 일정 각도를 이루며 교차하는 두 개의 축이 회전력을 자유로이 전달할 수 있도록 하기 위한 수단으로서 유니버설 조인트가 사용되고 있다.Universal joints are mainly used as a means for allowing two axes intersecting at a certain angle to freely transmit rotational force to a part where the steering column and the steering gear are connected to each other.

이러한 유니버설 조인트는 대체로 첨부도면 도 1에 도시된 바와 같이, 구동축(10)에 형성된 제1요크(11)와, 피동축(20)에 형성된 제2요크(21), 이들 요크(11,21)에 각각 형성되어 있는 이어 호울(ear hole;11a,21a)에 십자형으로 결합되는 스파이더(30), 그리고, 요크(11,21)의 이어 호울(11a,21a)과 스파이더(30)의 사이에 각각 개재되어 조인트의 회전이 원활하게 이루어지도록 지지하는 니들 베어링(40)으로 구성되어 있다.As shown in FIG. 1, the universal joint includes a first yoke 11 formed on the drive shaft 10, a second yoke 21 formed on the driven shaft 20, and these yokes 11 and 21. The spider 30 is crosswise coupled to the ear holes 11a and 21a which are formed in the respective holes, and between the ear holes 11a and 21a of the yokes 11 and 21 and the spider 30, respectively. Interposed is composed of a needle bearing 40 for supporting the joint to be smoothly rotated.

그리고, 이들 구성 요소에 대한 조립은 다음과 같은 순서에 따라 행하게 된다. 먼저, 제1요크(11)의 이어 호울(11a)에 스파이더(30)의 좌우 양단(31)을 삽입하고, 이 삽입부의 이어 호울(11a)과 스파이더(30)의 좌우 양단(31) 사이에 각각 니들 베어링(40)을 압입한 뒤 코킹(caucking)을 한다. 이어서, 제2요크(21)의 이어 호울(21a)에 스파이더(30)의 상하 양단(32)이 삽입되도록 결합시키고, 그 삽입부의 이어 호울(21a)과 스파이더(30)의 상하 양단(32) 사이에 각각 또다른 니들 베어링(40)들을 압입한 뒤 코킹을 함으로써 조립을 완료한다.The assembly of these components is performed in the following order. First, the left and right ends 31 of the spider 30 are inserted into the ear holes 11a of the first yoke 11, and between the ear holes 11a and the left and right ends 31 of the spider 30 of the insertion portion. The needle bearing 40 is press-fitted after each caulking. Subsequently, the upper and lower ends 32 of the spider 30 are coupled to the ear holes 21a of the second yoke 21, and the ear holes 21a and the upper and lower ends 32 of the spider 30 of the insertion portion are inserted. The assembly is completed by press-fitting each other needle bearing 40 between and then caulking.

한편, 상기 구성 요소들 중, 니들 베어링(40)의 구조가 도 2에 예시되어 있다. 도면에서 볼 수 있는 바와 같이, 니들 베어링(40)은 원통형의 하우징(41) 내주면에 일련의 니들 로울러(42)가 둘러져 설치된 구조로 이루어져 있다. 특히, 원통형 하우징(41)의 외주면은 동일 지름으로 되어 있어, 요크(11,21)의 이어 호울(11a,21a)에 스파이더(30)가 삽입된 상태에서 니들 베어링(40)의 하우징(41)이 이어 호울(11a,21a)에 압입될 때 하우징(41)의 접촉면이 동일한 공차로 압입되는 구조를 갖게 된다.Meanwhile, among the above components, the structure of the needle bearing 40 is illustrated in FIG. 2. As can be seen in the figure, the needle bearing 40 has a structure in which a series of needle rollers 42 are surrounded and installed on the inner circumferential surface of the cylindrical housing 41. In particular, the outer circumferential surface of the cylindrical housing 41 has the same diameter, and the housing 41 of the needle bearing 40 in the state where the spider 30 is inserted into the ear holes 11a and 21a of the yokes 11 and 21. This is followed by a structure in which the contact surface of the housing 41 is press-fitted with the same tolerances when pressed in the holes (11a, 21a).

그런데, 이와 같이 니들 베어링(40)의 하우징(41)이 전체적으로 동일한 직경으로 이루어짐으로써 요크(11,21)의 이어 호울(11a,21a)에 동일한 공차로 압입이 되는 구조하에서는, 불안정한 조립이 이루어진 경우에 니들 베어링(40)이 요크(11,21)의 이어 호울(11a,21a) 안에서 헛도는 현상이 발생하게 되고, 시간이 경과함에 따라 유격(遊動離隔)이 과다해져 소음이 발생하게 되는 문제점이 있다.
However, when the housing 41 of the needle bearing 40 is made of the same diameter as a whole, the structure is press-fitted into the ear holes 11a and 21a of the yokes 11 and 21 with the same tolerance, when unstable assembly is made. The needle bearing 40 has a phenomenon in which the needle bearing 40 loses its shape in the ear holes 11a and 21a of the yokes 11 and 21, and as time passes, the play is excessive and noise is generated. There is this.

본 발명은 전술한 바와 같은 종래 기술의 문제점을 개선하기 위해 안출된 것으로서, 그 목적은, 요크의 이어 호울에 대한 압입 설치시 불안정한 조립으로 인한 헛돎 현상과 소음발생이 방지될 수 있는 유니버설 조인트용 니들 베어링을 제공하는 데에 있다.
The present invention has been made to improve the problems of the prior art as described above, the object of the needle for the universal joint that can prevent the occurrence of noise and noise caused by unstable assembly during the indentation installation to the ear hole of the yoke To provide a bearing.

위와 같은 목적을 달성하기 위한 본 발명에 따른 유니버설 조인트용 니들 베어링은, 하우징의 내주면에 일련의 니들 로울러가 설치된 구조로 이루어져 요크의 이어 호울과 스파이더의 사이에 압입되는 유니버설 조인트용 니들 베어링에 있어 서, 상기 하우징이 상기 이어 호울에 순차적으로 압입력이 증가하며 압입되도록 테이퍼 가공된 것을 특징으로 한다.
Universal joint needle bearing according to the present invention for achieving the above object is composed of a structure in which a series of needle rollers are installed on the inner peripheral surface of the housing in the universal joint needle bearing pressed between the yoke's ear hole and the spider The housing is tapered so that the pressing force is sequentially increased in the ear hole.

이하에서는 본 발명의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 3은 본 발명에 따른 니들 베어링의 외관을 나타낸 사시도로서, 본 발명의 니들 베어링이 적용되는 유니버설 조인트에 대해서는 전술한 종래 기술의 설명으로 갈음하고 여기서는 본 발명의 특징부만을 설명한다.Figure 3 is a perspective view showing the appearance of the needle bearing according to the present invention, with respect to the universal joint to which the needle bearing of the present invention is applied, replaced with the above description of the prior art, and only the features of the present invention will be described herein.

도면에 도시된 바와 같이, 본 발명의 니들 베어링(40')은, 하우징(41')의 내주면에 일련의 니들 로울러(42')가 설치된 구조로 이루어져 있으며, 요크의 이어 호울에 스파이더가 삽입된 상태에서 이어 호울에 압입된다(요크와 스파이더의 구성은 전술한 종래 기술 참조). 특히, 하우징(41')의 외주면은 직경이 점증(또는 점감)하는 구조를 갖도록 소정 각도(α)로 테이퍼 가공되어 있다. 이에 따라, 본 발명의 니들 베어링(40')은, 요크의 이어 호울에 스파이더가 삽입된 상태에서 이어 호울 내에 압입될 때, 직경이 작은 부분부터 큰 부분에 이르기까지 순차적으로 압입됨으로써 압입력이 점점 증가하면서 설치가 이루어지게 된다.As shown in the figure, the needle bearing 40 'of the present invention has a structure in which a series of needle rollers 42' are installed on an inner circumferential surface of the housing 41 ', and a spider is inserted into an ear hole of the yoke. Then it is pressed into the hole in the state (for the configuration of the yoke and the spider, see the above-mentioned prior art). In particular, the outer peripheral surface of the housing 41 'is tapered at a predetermined angle α so as to have a structure in which the diameter increases (or decreases). Accordingly, when the needle bearing 40 'of the present invention is press-fitted into the ear hole while the spider is inserted into the ear hole of the yoke, the press-in input is gradually pressurized by sequentially pressing from the small diameter part to the large part. Increasingly, installation is achieved.

이와 같이, 본 발명의 니들 베어링(40')은, 하우징(41')의 외주면이 테이퍼 가공된 구조를 가짐으로써, 요크의 이어 호울에 압입될 때 매우 안정적으로 압입이 이루어지게 된다.
Thus, the needle bearing 40 'of the present invention has a structure in which the outer circumferential surface of the housing 41' is tapered, so that the needle bearing 40 'is pressurized very stably when pressed into the ear hole of the yoke.

이상에서 설명한 바와 같이, 본 발명에 따른 유니버설 조인트용 니들 베어링은, 요크의 이어 호울에 압입될 때 매우 안정적으로 압입이 이루어지는 구조를 가짐으로써, 종래의 불안정한 조립으로 인한 헛돎 현상과 소음발생을 배제하고 유니버설 조인트의 원활한 작동에 기여하는 효과를 발휘한다.As described above, the needle bearing for universal joints according to the present invention has a structure in which the needle bearing is pressurized very stably when pressed into the ear hole of the yoke, thereby eliminating waste and noise caused by conventional unstable assembly. It contributes to the smooth operation of the universal joint.
