이하 첨부된 도면을 참고하여 본 발명의 실시예를 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1 및 도 2는 본 발명의 일 실시예에 따른 베어링 조립 장치의 사시도이다.1 and 2 are perspective views of a bearing assembly apparatus according to an embodiment of the present invention.
도 1 및 도 2에 도시한 바와 같이 본 발명의 일 실시예에 따른 베어링 조립 장치는 대차(100), 구동 암(200), 히팅 부재(300) 및 지지 부재(210)를 포함할 수 있다.1 and 2, the bearing assembly apparatus according to an embodiment of the present invention may include a bogie 100, a drive arm 200, a heating member 300, and a support member 210.
대차(100)는 복수의 바퀴(101)를 구비함으로써 지면을 따라 이동 가능하도록 마련될 수 있다.The bogie 100 may be provided to be movable along the ground by having a plurality of wheels 101.
복수의 바퀴(101)에는 각각 브레이크와 같은 제동 장치가 구비됨으로써 베어링 조립 작업 중 베어링 조립 장치가 조립 과정 중에 이동되지 않도록 고정될 수 있다.The plurality of wheels 101 are each provided with a braking device such as a brake, so that the bearing assembling device can be fixed during the assembling process during the assembling process.
대차(100)의 상면에는 회전 가능한 회전축(110)이 형성될 수 있다.A rotatable rotary shaft 110 may be formed on the upper surface of the carriage 100.
회전축(110)은 구동 암(200)의 일단이 회전 지지되도록 하며, 구동 암(200)은 외팔보 형상으로 길이가 가변되도록 형성될 수 있다.The rotary shaft 110 is rotatably supported at one end of the driving arm 200, and the driving arm 200 is formed in a cantilever shape so as to have a variable length.
구동 암(200)은 내측 암(202) 및 외측 암(201)을 포함할 수 있다.The driving arm 200 may include an inner arm 202 and an outer arm 201.
내측 암(202)은 중공의 사각형의 횡단면 형상을 갖도록 형성될 수 있다. 또한, 내측 암(202)의 표면이 외측 암(201)의 내측 벽에 밀착되도록 형성됨으로써 내측 암(202)이 외측 암(201)의 내측 벽면을 따라 슬라이딩되도록 한다.The inner arm 202 may be formed to have a hollow rectangular cross-sectional shape. The inner arm 202 is formed to be in close contact with the inner wall of the outer arm 201 so that the inner arm 202 is slid along the inner wall surface of the outer arm 201.
다시 말해, 내측 암(202)이 외측 암(201)의 내측 벽면을 따라 길이 방향으로 왕복 이동되면 내측 암(202) 및 외측 암(201)의 총 길이가 가변될 수 있도록 한다.In other words, when the inner arm 202 is reciprocated longitudinally along the inner wall surface of the outer arm 201, the total length of the inner arm 202 and the outer arm 201 can be varied.
내측 암(202)의 회전 반경 외측 단부에는 지지 부재(210)가 형성될 수 있다.A support member 210 may be formed at an outer end portion of the inner radius of the rotation arm 202.
지지 부재(210)는 내측 암(202)의 단부에서 회전 가능하도록 결합될 수 있다.The support member 210 may be rotatably coupled at the end of the inner arm 202.
또한, 지지 부재(210)는 내측 암(202)에 설치되어 회전되되, 지지 부재(210)의 하단을 관통하는 지지축(220)이 내측 암(202)을 관통하여 결합되어 회전될 수 있다.The supporting member 210 is installed on the inner arm 202 and rotated while a supporting shaft 220 passing through the lower end of the supporting member 210 is coupled through the inner arm 202 and rotated.
지지축(220)의 일단에는 지지 부재(210)의 높이를 조절할 수 있도록 조절 핸들(221)이 구비될 수 있다.At one end of the support shaft 220, a control handle 221 may be provided to adjust the height of the support member 210.
조절 핸들(221)은 지지축(220)과 동축 상에 배치되고, 별도의 너트 부재(미도시) 및 와셔(미도시)가 개재되도록 나사결합됨으로써 조절 핸들(221)의 회전에 따라 지지 부재(210)의 높이가 조절될 수 있도록 한다.The adjustment handle 221 is disposed coaxially with the support shaft 220 and is screwed so that a separate nut member (not shown) and a washer (not shown) are interposed therebetween, 210 can be adjusted in height.
한편, 구동 암(200)에는 히팅 부재(300)가 구비될 수 있다.Meanwhile, the driving arm 200 may be provided with a heating member 300.
히팅 부재(300)는 히터 단자 박스(미도시) 및 히터 제어 박스(미도시)를 포함할 수 있으며, 베어링(B)의 내륜과 상호 전기적으로 연결되는 전선(미도시)을 통하여 접촉되는 히터 프로브(미도시)가 구비될 수 있다. 상기 히터 프로브는 베어링(B)의 내륜과 근접하도록 적어도 3개소에 접촉됨으로써 전기적 가열을 수행할 수 있도록 한다.The heating member 300 may include a heater terminal box (not shown) and a heater control box (not shown), and may include a heater probe (not shown), which is in contact with an inner ring of the bearing B via an electric wire (not shown) (Not shown) may be provided. The heater probe is brought into contact with at least three points so as to be close to the inner ring of the bearing (B) so that electric heating can be performed.
상기 히터 프로브는 알루미늄 재질로 이루어질 수 있다. 알루미늄의 열전도율은 금, 은, 구리에 이은 4위이고, 상기 나열한 금속보다 저렴하고 경도, 인장강도, 항복강도, 강성 등의 기계적 성질이 우수하기 때문에 열전달을 해야 하는 히터 프로브의 재질로 사용될 수 있다.The heater probe may be made of aluminum. The thermal conductivity of aluminum is 4th place after gold, silver and copper. It is cheaper than the metals listed above and can be used as a material of a heater probe to be heat-transferred because of its excellent mechanical properties such as hardness, tensile strength, yield strength and rigidity .
발열체(미도시)는 상기 히터 프로브에 구비되고 전기에 의해 발열되도록 이루어질 수 있다.A heating element (not shown) may be provided in the heater probe and generate heat by electricity.
다시 말해, 발열체는 전기가 공급되면 발열하여 베어링(B)을 가열시킬 수 있다. 상기 히터 프로브는 발열체와 전기적으로 연결될 수 있으며, 전선이 발열체와 연결되어 전원을 공급할 수 있다.In other words, the heating element can heat the bearing (B) by heating when electricity is supplied. The heater probe may be electrically connected to the heating element, and the electric wire may be connected to the heating element to supply power.
지지 부재(210)의 외측 면에는 사용자가 손으로 파지하여 구동시킬 수 있는 파지 부재(211)가 형성될 수 있다. 파지 부재(211)는 지지 부재(210)의 외측면으로부터 일체로 연장되되 사용자가 손으로 파지할 수 있는 길이 및 굵기로 형성될 수 있다.A gripping member 211 can be formed on an outer surface of the support member 210, which can be gripped by a user and driven. The grip member 211 may be integrally extended from the outer surface of the support member 210 and may have a length and thickness that the user can grasp by hand.
전술한 바와 같이 이루어진 본 발명의 일 실시예에 따른 베어링 조립 장치의 작동을 설명하면 다음과 같다.The operation of the bearing assembly apparatus according to an embodiment of the present invention will now be described.
우선, 조립하고자 하는 베어링을 지지 부재(210)에 위치시킨 상태에서, 베어링(B)과 결합될 샤프트(미도시)가 구비되면 작업자가 파지 부재(211)를 파지한 상태로 회전축(110)을 중심으로 소정 각도만큼 구동 암(200)을 회전시킨다.When a shaft (not shown) to be coupled with the bearing B is provided in a state where the bearing to be assembled is positioned on the supporting member 210, the operator holds the rotating shaft 110 in a state of holding the holding member 211 The driving arm 200 is rotated by a predetermined angle with respect to the center.
여기서, 상기 샤프트가 베어링(B)과 근접한 상태에서 조절 핸들(221)을 회전시켜 상기 샤프트의 중심과 베어링(B)의 중심이 일치되도록 조절한다.Here, the adjustment handle 221 is rotated in a state where the shaft is in close proximity to the bearing B so that the center of the shaft and the center of the bearing B coincide with each other.
조절 핸들(221)을 회전시킴으로써 지지 부재(210)를 상승 및 하강시켜 베어링의 내륜의 중심과 샤프트의 중심을 맞춘다.By rotating the adjustment handle 221, the support member 210 is lifted and lowered to align the center of the shaft with the center of the inner ring of the bearing.
이후, 대차(100)에 구비된 복수의 바퀴(101)를 제동시키고, 히팅 부재(300)의 전원부(미도시)에 마련된 콘센트를 연결하고, 프로브 거치대에 거치된 히터 프로브를 베어링의 내륜에 부착하면 자석에 의해 고정된다.Thereafter, a plurality of wheels 101 provided on the bogie 100 are braked, an outlet provided in a power supply unit (not shown) of the heating member 300 is connected, and a heater probe mounted on the probe base is attached to the inner ring of the bearing When it is fixed by the magnet.
히팅 부재(300)가 작동되면 히터 프로브 내부의 발열체가 발열하여 베어링을 가열시키고 가열된 베어링(B)은 열팽창이 일어나 베어링(B)의 내륜의 직경이 확장된다.When the heating member 300 is operated, the heating element inside the heater probe generates heat to heat the bearing, and the heated bearing B thermally expands to enlarge the diameter of the inner ring of the bearing B.
이후, 파지 부재(211)를 파지한 상태로 회전축(110)을 중심으로 더욱 회전시키면 상기 샤프트의 외주면에 베어링(B)의 내륜이 끼워지게 되고, 이때 지지 부재(210)가 회전됨과 동시에 구동 암(200)의 내측 암(202)이 외측 암(201)의 내부로부터 신장되는 방향으로 길이가 가변된다.The inner ring of the bearing B is fitted to the outer circumferential surface of the shaft when the gripping member 211 is further rotated about the rotational axis 110 while holding the gripping member 211. At this time, The length of the inner arm 202 of the arm 200 varies in a direction in which it extends from the inside of the outer arm 201.
따라서, 베어링(B)과 상기 샤프트의 결합 시의 높이 및 각도가 일정하게 유지되므로 안정적인 결합이 이루어질 수 있게 된다.Accordingly, since the height and angle of the bearing B and the shaft are kept constant, stable engagement can be achieved.
