이탈방지형 테이퍼 롤러 베어링Detachable tapered roller bearing

본 고안은 수동 변속기 등에 구비되어 회전하는 샤프트를 지지하는 테이퍼 롤러 베어링에 관한 것으로서, 특히 내륜을 자화(磁化)시켜 롤러가 이탈되지 않도록 한 이탈방지형 테이퍼 롤러 베어링에 관한 것이다.The present invention relates to a tapered roller bearing provided on a manual transmission and the like to support a rotating shaft, and more particularly, to a taper roller bearing that is prevented from detaching the roller by magnetizing the inner ring.

도 1은 수동 변속기의 내부 구조를 나타낸 도면으로서, 클러치로부터 동력을 받아 회전하는 입력 샤프트(11)와, 상기 입력 샤프트(11)의 동력을 전달받아 회전하면서 종감속 장치를 회전시키는 메인 샤프트(12)와, 상기 메인 샤프트(12)의 하측에 위치되고 상기 입력 샤프트(11)의 동력을 전달받아 상기 메인 샤프트(12)에 전달하되 일정한 속도비가 형성되도록 하는 카운터 샤프트(13)와, 내부의 샤프트(11,12,13) 및 기어를 보호하는 변속기 케이스(14)와, 상기 변속기 케이스(14)에 연결되어 상기 메인 샤프트(12)를 지지하는 익스텐션 하우징(15)으로 구성되어 있다.FIG. 1 is a view illustrating an internal structure of a manual transmission, in which an input shaft 11 rotates by receiving power from a clutch, and a main shaft 12 that rotates a longitudinal reduction device while rotating by receiving power from the input shaft 11. And a counter shaft 13 positioned below the main shaft 12 to receive power from the input shaft 11 and transmit the power to the main shaft 12 to form a constant speed ratio. (11, 12, 13) and a transmission case (14) for protecting the gear, and an extension housing (15) connected to the transmission case (14) to support the main shaft (12).

이와 같은 수동 변속기에서 상기 입력 샤프트(11), 메인 샤프트(12), 카운터 샤프트(13) 등이 변속기 케이스(14)에 지지되면서도 용이하게 회전되도록 여러 종류의 변속기용 베어링(20)이 설치되어 있다.In the manual transmission, various types of transmission bearings 20 are installed such that the input shaft 11, the main shaft 12, the counter shaft 13, and the like are easily supported by the transmission case 14. .

여기서, 도 1의 확대도는 변속기용 베어링(20) 중에서도 테이퍼 롤러 베어링(25)이 설치된 부분의 확대도이고, 상기 테이퍼 롤러 베어링(25)은 환형으로 형성되어 카운터 샤프트(13) 둘레에 끼워져서 변속기 케이스(14)의 내벽에 고정되게 된다.Here, an enlarged view of FIG. 1 is an enlarged view of a portion in which a tapered roller bearing 25 is installed among the transmission bearings 20, and the tapered roller bearing 25 is formed in an annular shape and fitted around the counter shaft 13. The inner wall of the transmission case 14 is fixed.

이와 같은 테이퍼 롤러 베어링(25)은 상기 카운터 샤프트(13)의 둘레에 외삽 고정되어 카운터 샤프트(13)와 동시에 회전되는 내륜(25a)과, 상기 내륜(25a)의 외주측에 위치되며 상기 변속기 케이스(14)에 고정되는 외륜(25b)과, 상기 내륜(25a)과 외륜(25b) 사이에 위치되어 상기 카운터 샤프트(13)의 회전 저항을 최소화시키는 롤러(25c)로 이루어져 있다.The tapered roller bearing 25 is externally fixed around the counter shaft 13 and rotated at the same time as the counter shaft 13, and is positioned on the outer circumferential side of the inner ring 25 a and the transmission case. An outer ring 25b fixed to 14 and a roller 25c positioned between the inner ring 25a and the outer ring 25b to minimize the rotational resistance of the counter shaft 13.

그러나 상기한 바와 같은 테이퍼 롤러 베어링(25)의 경우 내륜(25a)과 외륜(25b)이 롤러(25c)를 사이에 두고 서로 분리되어 있으므로 변속기를 운반시에 충격이 가해지거나 조립 및 탈거시에 내륜(25a)과 외륜(25b) 사이에 든 롤러(25c)가 분해되기 쉬워 작업자의 특별한 주의가 요구된다.However, in the tapered roller bearing 25 as described above, since the inner ring 25a and the outer ring 25b are separated from each other with the roller 25c in between, an impact is applied when the transmission is transported or an inner ring when assembled and removed. The roller 25c sandwiched between the 25a and the outer ring 25b tends to be disassembled, and special care of the operator is required.

또한 상기 테이퍼 롤러 베어링(25)의 내구 부족 등으로 마모가 발생되거나 동력 전달 과정에서 카운터 샤프트(13)에 추력(F)이 발생될 경우 내륜과 외륜 사이의 롤러(25c)가 이탈될 수도 있다. 이때에는 이탈된 롤러(25c)가 회전하는 변속 기어 사이에 끼워져 변속기의 내구에 심대한 손상을 미치게 되는 문제점도 발생되었다.In addition, when wear occurs due to insufficient durability of the tapered roller bearing 25 or when thrust F is generated on the counter shaft 13 in the power transmission process, the roller 25c between the inner and outer rings may be separated. At this time, the detached roller 25c is sandwiched between the rotating transmission gears, causing serious damage to the durability of the transmission.

본 고안은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 내륜을 자화하여 롤러 및 외륜이 내륜측에 항상 붙어 있도록 구성함으로써 롤러의 이탈이 방지되어 변속기의 손상이 방지되도록 하는 이탈방지형 테이퍼 롤러 베어링을 제공하는 데 있다.The present invention has been devised to solve the above problems, by magnetizing the inner ring so that the roller and the outer ring is always attached to the inner ring side to prevent the separation of the roller to prevent the tapered roller bearing to prevent damage to the transmission To provide.

상기한 과제를 실현하기 위한 본 고안의 이탈방지형 테이퍼 롤러 베어링은, 변속기 케이스에 회전하는 샤프트를 지지토록 내륜, 롤러, 외륜으로 이루어진 테이퍼 롤러 베어링에 있어서, 상기 내륜은 그 외측에 위치되는 롤러가 자력의 의해 붙어 있도록 자화(磁化)된 것을 특징으로 한다.The tapered roller bearing of the present invention for realizing the above object is a tapered roller bearing consisting of an inner ring, a roller, and an outer ring to support a shaft rotating to a transmission case, wherein the inner ring has a roller located outside thereof. It is characterized in that it is magnetized to be stuck by magnetic force.

이하, 첨부된 도면을 참조하여 본 고안의 실시 예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

도 2는 본 고안의 이탈방지형 테이퍼 롤러 베어링의 설치 구조가 도시된 도면이다.Figure 2 is a view showing the installation structure of the separation prevention tapered roller bearing of the present invention.

도 2에 도시된 바와 같이 테이퍼 롤러 베어링(70)은 샤프트(50)에 고정된 내륜(72)과, 변속기 케이스(60)의 내벽측에 고정되는 외륜(74)과, 상기 내륜(72)과 외륜(74)사이에 경사진 방향으로 끼워져 있는 롤러(76)로 이루어져 있다.As shown in FIG. 2, the tapered roller bearing 70 includes an inner ring 72 fixed to the shaft 50, an outer ring 74 fixed to an inner wall side of the transmission case 60, and the inner ring 72. It consists of a roller 76 fitted in the inclined direction between outer ring 74. As shown in FIG.

특히 상기 내륜(72)은 자력을 갖도록 자화(磁化)되어 쇠 등의 금속으로 이루어진 상기 롤러(76) 및 외륜(74)이 자력에 의해 항상 내륜(72)측에 붙어있게 되어 있다.In particular, the inner ring 72 is magnetized so as to have a magnetic force, and the roller 76 and outer ring 74 made of metal such as steel are always attached to the inner ring 72 side by magnetic force.

여기서 상기 내륜(72)은 내구성이 유지되는 자성체로 이루어질 수도 있고, 금속성을 자화시켜 자성을 갖도록 형성할 수도 있다.In this case, the inner ring 72 may be formed of a magnetic material that maintains durability, or may be formed to magnetize metallic properties to have magnetic properties.

이와 같은 자화된 내륜(72)이 구비되어 있는 테이퍼 롤러 베어링(70)은 베어링을 파손시킬 수 있는 상당한 힘을 가하지 않는 이상 상기 내륜(72)의 자력에 의해 롤러(76) 및 외륜(74)이 내륜과 상호 밀착되어 있기 때문에 베어링이 쉽게 파손되지 않게 되고, 롤러(76)의 이탈도 일어나지 않게 된다.The tapered roller bearing 70 is provided with the magnetized inner ring 72, the roller 76 and the outer ring 74 by the magnetic force of the inner ring 72, unless a significant force that can damage the bearing is applied Since the bearings are in close contact with each other, the bearings are not easily broken, and the roller 76 is not detached.

그리고 오랜 시간 사용으로 롤러(76)가 마모되어도 내륜(72)의 자력에 의해 롤러(76)가 이탈되지 않기 때문에 정비할 때 롤러(76)가 내륜(72)에 그대로 붙어 있는 상태에서 간편하게 점검할 수 있게 된다.Since the roller 76 is not detached by the magnetic force of the inner ring 72 even if the roller 76 wears out due to long time use, the roller 76 remains attached to the inner ring 72 as it is. It becomes possible.

따라서, 상기한 바와 같은 본 고안의 이탈방지형 테이퍼 롤러 베어링은 자화된 내륜에 의해 롤러의 이탈을 최소화시키기 때문에 운반 및 조립시 롤러가 이탈되지 않아 작업의 편의성이 향상됨은 물론 오랜 사용으로 롤러가 마모되어도 쉽게 이탈되지 않으므로 롤러의 이탈로 인한 변속기의 손상을 방지할 수 있게 된다.Therefore, the taper roller bearing of the present invention as described above minimizes the detachment of the roller by the magnetized inner ring so that the roller is not detached during transportation and assembly, thereby improving the convenience of work and of course the wear of the roller for a long time. It is possible to prevent damage to the transmission due to the detachment of the roller because it is not easily detached even if it is.
