이와 같은 목적을 달성하기 위한 본 발명의 베어링용 틈새조절장치는, 그 고정체와 회전체의 사이에 설치되어 회전을 지지하도록 마련된 베어링의 내경측 또는 외경측에서 축방향 양측으로 경사지게 형성되는 경사면과, 이 경사면과 대응되도록 경사지게 형성된 조절면을 구비하여 상기 베어링의 축방향 양측으로 배치되는 조절부로 이루어진 것을 특징으로 한다.The clearance gap adjusting device for a bearing of the present invention for achieving the above object is provided between the fixed body and the rotating body, the inclined surface formed inclined in both the axial direction at the inner diameter side or outer diameter side of the bearing provided to support rotation; It is characterized by consisting of a control unit disposed on both sides in the axial direction of the bearing having a control surface formed inclined to correspond to the inclined surface.

이하에서는 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

도 1은 본 발명에 따른 1실시예인 압입식 틈새조절장치를 보인 단면도이고, 도 2는 이의 변형예를 보인 단면도이다. 이에 도시된 바와 같이, 하우징의 내부에 샤프트가 설치되고 그 사이에는 베어링이 설치된다.1 is a cross-sectional view showing a press-fitting gap adjusting device according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a modification thereof. As shown therein, a shaft is installed inside the housing and a bearing is installed therebetween.

먼저, 베어링(10)은 내경부(11)와 외경부(12) 사이에 볼 및 핀 등의 마찰감소수단이 설치되어 내경부(11)와 외경부(12)에 각각 설치되는 샤프트와 하우징 사이의 회전이 원활해지도록 지지하는 것으로서, 본 발명에서는 볼(13)이 구비된 볼베어링을 예를 들어 설명한다.First, the bearing 10 has a friction reducing means such as a ball and a pin installed between the inner diameter portion 11 and the outer diameter portion 12 and is disposed between the shaft and the housing respectively installed at the inner diameter portion 11 and the outer diameter portion 12. As to support the smooth rotation of the ball, in the present invention, a ball bearing provided with the ball 13 will be described as an example.

다음, 베어링(10)의 내,외측에 설치되는 샤프트와 하우징은 그 설치 목적에 따라 하우징을 기준으로 샤프트가 회전되는 경우가 있고, 샤프트를 기준으로 하우징이 회전되는 경우가 있는데, 본 발명에서는 하우징을 고정체(30)로 구비하고, 샤프트를 회전체(20)로 구비하는 것을 예를 들어 설명한다.Next, the shaft and the housing installed on the inside and the outside of the bearing 10, the shaft may be rotated relative to the housing according to the installation purpose, the housing may be rotated relative to the shaft, in the present invention the housing Is provided with the stationary body 30, and the shaft is provided with the rotating body 20, for example.

한편, 틈새조절장치는 베어링(10)의 내경측 또는 외경측에 축방향 양측으로 경사지게 형성되는 경사면(15)과, 이 경사면(15)과 대응되도록 경사지게 형성된 조절면(55)을 구비하여 상기 베어링(10)의 축방향 양측으로 배치되는 조절부(50)로서 이루어진다.On the other hand, the gap adjusting device is provided with an inclined surface 15 which is formed to be inclined to both sides in the axial direction on the inner diameter side or the outer diameter side of the bearing 10, and the control surface 55 formed to be inclined to correspond to the inclined surface 15, the bearing It consists of the adjustment part 50 arrange | positioned at the axial direction both sides of (10).

조절부(50)는 베어링(10)과 고정체(30) 및 회전체(20)의 사이에 압입되어 설치되고, 틈새의 조절은 조절부(50)를 축방향으로 가압하여, 조절면(55)과 경사면(15)에 의한 조절부(50)의 이동으로 가능해진다.The adjusting part 50 is press-fitted between the bearing 10, the fixed body 30, and the rotating body 20, and the adjustment of the gap presses the adjusting part 50 in the axial direction, thereby adjusting the adjusting surface 55. ) And the adjustment unit 50 by the inclined surface 15 are enabled.

도 3은 본 발명에 따른 2실시예인 나사식 틈새조절장치를 보인 단면도이고, 도 4는 도 3의 변형예를 보인 단면도이다. 이에 도시된 바와 같이, 보다 용이하게 틈새조절을 이룰 수 있도록 베어링(10)의 축방향 일측에 배치되는 조절부(50)에는 조절나사(56)가 형성되어 있고, 이 조절나사(56)에 대응되도록 고정체(30) 및 회전체(20)에는 고정나사(36)와 회전나사(26)가 형성되어 있다.Figure 3 is a cross-sectional view showing a two-screw thread gap adjusting apparatus according to the present invention, Figure 4 is a cross-sectional view showing a modification of FIG. As shown in the figure, an adjustment screw 56 is formed on the adjustment part 50 disposed on one side of the bearing 10 in the axial direction so that the clearance adjustment can be made more easily, and corresponds to the adjustment screw 56. Fixing screw (36) and rotating screw (26) are formed in the fixed body (30) and the rotating body (20).

축방향 타측 조절부(50)는 압입되어 베어링(10)과 고정체(30) 및 회전체(20)에 밀착 고정되어서, 틈새 조절시에는 조절나사(56)가 마련된 조절부(50)를, 그 외부를 감싸는 공구를 이용하여 회전시키면 된다.The other axial adjustment part 50 is press-fitted and fixed to the bearing 10, the fixed body 30, and the rotating body 20 so that the adjustment part 56 provided with the adjustment screw 56 is provided at the time of clearance adjustment. The tool may be rotated using a tool surrounding the outside.

이로써, 상기 축방향 일측의 조절부(50)가 나사체결에 의해 축방향으로 이동됨에 따라 양측 조절부(50)의 조절면(55)과 이에 대응되는 경사면(15)이 밀착되어 조절부(50)를 이동시킴에 따라 반경방향 틈새가 조절가능해진다.As a result, as the adjusting part 50 on one side of the axial direction is moved in the axial direction by screwing, the adjusting surface 55 and the inclined surface 15 corresponding to the adjusting parts 50 of the both side adjusting parts 50 are in close contact with each other. By moving), the radial clearance becomes adjustable.

도 5는 본 발명에 따른 3실시예인 체결식 틈새조절장치를 보인 단면도이고, 도 6은 도 5의 축방향의 정면도이다. 이에 도시된 바와 같이, 베어링(10)의 축방향 양측으로 마련되는 조절부(50) 사이의 간격을 조절하여 틈새를 조절하는 구조이다.5 is a cross-sectional view showing a fastening clearance adjusting device which is a third embodiment according to the present invention, and FIG. 6 is a front view of the axial direction of FIG. 5. As shown in the figure, it is a structure for adjusting the gap by adjusting the gap between the adjusting unit 50 provided on both sides of the bearing 10 in the axial direction.

즉, 베어링(10)을 사이에 두고 그 양측에 배치되는 조절부(50)에는 서로 연통되도록 조절공(57)이 형성되고, 이 조절공(57)의 내부에는 일단에 형성된 머리에 의해 일측에 고정되는 조절볼트(58)가 설치되며, 이 조절볼트(58)의 타단에는 조절부(50) 사이의 간격을 조절할 수 있도록 조절너트(59)가 체결된다.That is, the adjustment hole (57) is formed so as to communicate with each other in the control unit 50 disposed on both sides with the bearing 10 therebetween, and the inside of the control hole (57) on one side by the head formed at one end The adjustment bolt 58 is installed to be fixed, and the adjustment nut 59 is fastened to the other end of the adjustment bolt 58 to adjust the gap between the adjustment unit 50.

이때, 조절공(57)은 서로 대응되는 위치에 다수개가 형성되고, 이 조절공(57)에는 상기 조절볼트(58)와 조절너트(59)가 각각 설치되는데, 본 발명에서는 사방으로 서로 대칭되도록 직각 간격으로 네 개의 조절공(57) 및 조절볼트(58)와 조절너트(59)가 마련된다.At this time, the adjustment hole 57 is formed in a plurality corresponding to each other, the adjustment hole 57 is provided with the adjustment bolt 58 and the adjustment nut 59, respectively, in the present invention to be symmetrical with each other in all directions Four adjusting holes 57 and adjusting bolts 58 and adjusting nuts 59 are provided at right angles.

이로써, 조절너트(59)를 정회전시키거나 역회전시켜 조절부(50)를 축방향 이동시킴에 따라 그 틈새의 조절이 가능해진다.As a result, the clearance can be adjusted by moving the adjusting part 50 in the axial direction by rotating the adjusting nut 59 forward or reverse.

이와 같이 구성된 본 발명의 베어링용 틈새장치는, 베어링(10)의 축방향 양측에 경사면(15)을 형성하고, 이 베어링(10)의 축방향 양측에는 경사면(15)과 대응되는 조절면(55)을 가지는 조절부(50)를 설치한다.The bearing clearance device of this invention comprised in this way forms the inclined surface 15 in the axial direction both sides of the bearing 10, and the adjustment surface 55 corresponding to the inclined surface 15 in the axial both sides of this bearing 10. Install the adjusting unit 50 having a).

그리고, 조절부(50)를 축방향 이동시킴에 따라 조절부(50)의 조절면(55)과 베어링(10)의 경사면(15)에 의해 축방향 이동력이 반경방향 이동력으로 방향 전환됨으로 인해 조절부(50)가 틈새를 조절하게 된다.And, by moving the adjusting section 50 in the axial direction by the adjustment surface 55 of the adjusting section 50 and the inclined surface 15 of the bearing 10 is changed in the axial movement force to the radial movement force Due to the adjusting unit 50 to adjust the gap.

특히, 1실시예에서는 이러한 조절부(50)를 단순히 가압하여 축방향 이동시키고, 2실시예에서는 나사결합된 조절부(50)를 회전시켜 축방향 이동시키며, 3실시예 에서는 조절볼트(58)와 조절너트(59)를 통해 조절부(50)를 이동시켜 틈새를 용이하게 조절하게 된다.Particularly, in one embodiment, the control unit 50 is simply pressurized to move in the axial direction, in the second embodiment, the screwed control unit 50 is rotated to move in the axial direction, and in the third embodiment, the adjustment bolt 58 And adjust the clearance through the adjustment nut (59) to easily adjust the gap.

이상에서 설명한 바와 같이, 본 발명에 따른 베어링용 틈새조절장치는, 베어링의 축방향 양측으로 설치되는 조절부로 인해 베어링과 고정체 및 회전체의 틈새 조절이 용이해짐은 물론, 이로 인해 베어링을 회전체와 고정체 사이에 설치한 후 이동 및 분리가 용이하게 되는 이점이 있다.As described above, the bearing clearance adjusting device according to the present invention, the adjustment portion is installed on both sides of the bearing in the axial direction facilitates the clearance adjustment between the bearing, the fixed body and the rotating body, as a result of which the bearing is rotated There is an advantage that it is easy to move and remove after installing between the fixture.
