본 발명은 특허청구범위 독립항의 대개념에 의해 탄력에 의해 조정가능한 인장장치에 관한 것이다.The present invention relates to a tensioning device which is adjustable by elasticity by the large concept of the independent claims.

이러한 종류의 인장장치를 이미 독일특허출원(P 4 015 028.3)에 의하여 제안되었다. 이 특허는 편심조정륜(eccenric adjusting member)이 볼트상에 회전할 수 있게 배치되어 있고, 이에 의하여 모터블록에 고착시킬 수 있다. 편심작업륜(eccentric working member)이 그 위에 회전할 수 있게 장착되어 있다. 2개의 편심륜 사이에는 비틀림 스프링이 제공되어 있고, 이러한 비틀림 스프링은 편심조정륜상에서 편심작업륜의 활동적인 회전을 생기게 한다. 비틀림 스프링에 의해 구동벨트로 적용되는 인장롤러가 편심작업륜상에 제공된다. 이에 의하여 벨트에는 운전에 필요한 인장력이 생긴다. 2개의 편심륜에 의한 전술한 실시예는 큰 인장범위를 얻는다.A tension device of this kind has already been proposed by the German patent application (P 4 015 028.3). This patent arranges the eccenric adjusting member to rotate on the bolt, thereby fixing it to the motor block. An eccentric working member is rotatably mounted on it. A torsion spring is provided between the two eccentric wheels, which causes the active rotation of the eccentric work wheels on the eccentric adjustment wheels. A tension roller is provided on the eccentric work wheel which is applied by the torsion spring to the drive belt. As a result, the belt has a tensile force necessary for operation. The embodiment described above with two eccentric wheels achieves a large tensile range.

이러한 장치에 있어서는 편심조정륜에 의하여 편심작업륜에 작용하는 스프링이 조정용 공구에 의하여 예정된 평균작업점이 조정될때까지 인장된다. 이와 같은 작업점은 표시기에 의하여 2개의 편심륜에서 식별되며, 이는 스프링 작용력을 나타내며 이 스프링 작용력이 구동벨트의 예비인장을 제공하여 최종 장치에서 비틀림 스프링내의 오차가 보상되고 인장된 벨트 전달이 가능하게 된다.In such a device, the spring acting on the eccentric work wheel by the eccentric adjustment wheel is tensioned until the average work point predetermined by the adjustment tool is adjusted. This working point is identified on the two eccentric wheels by the indicator, which represents the spring force, which provides pretension of the drive belt, which compensates the errors in the torsion springs in the final device and enables the transfer of the tensioned belt. do.

또한 이 장치에서는 예비-인장 방향과 그 역방향 모두로 오차범위가 큰 때에는 회전중의 작업경로는 항상 같다. 이같은 편심작업륜은 편심조정륜의 원통형 표면상에서 회전할 수 있도록 장착되며 인장 롤러를 지닌다.In this apparatus, the working path during rotation is always the same when the error range is large both in the pre-tension direction and in the reverse direction. Such eccentric work wheels are mounted to rotate on the cylindrical surface of the eccentric adjustment wheels and have tension rollers.

제안된 인장장치의 조정을 쉽게 하기 위하여 2개의 편심륜 모두에 이른바, 표시기가 제공되어 있다. 이러한 표시기는 앞서 확정된 일정한 인장력의 조정을 단순화시킨다.In order to facilitate the adjustment of the proposed tensioning device, so-called indicators are provided on both eccentric rings. This indicator simplifies the adjustment of the constant tensile force previously established.

앞서 제안된 인장장치가 결합없이 가능할지라도, 특별한 상황에 있어서는 특정의 조건들이 개선을 필요로 한다. 길이의 오차를 예기하여 가능한 조정범위 대부분을 사용하는 것이 필요한 때에는 또 따른 측정을 채택하여 편심조정륜의 극단조정에서도 표시기에 의해 알 수 있는 인장이 일정하게 유지될 수 있도록 한다.Although the previously proposed tensioning device is possible without coupling, certain conditions require improvement in special circumstances. When it is necessary to anticipate the error of the length and use most of the possible adjustment ranges, further measurements are taken to ensure that the tension, as indicated by the indicator, remains constant even in the extreme adjustment of the eccentric adjustment wheel.

본 발명의 목적은 편심조정륜의 회전된 위치가 구동벨트에 작용하는 작용력에 아무런 영향을 미치지 않으며, 모터블럭에 대한 표시기 위치가 조정과정에 의해 변경되지 않아서 조립중에 관찰을 단순화하도록 앞서 언급한 타입의 인장장치를 제공하는 것이다.It is an object of the present invention that the rotated position of the eccentric adjustment wheel has no influence on the acting force acting on the drive belt, and the indicator position relative to the motor block is not changed by the adjustment process so as to simplify the observation during assembly. It is to provide a tensioning device.

본 발명에 따라, 고정된 지지대상의 고정볼트 둘레로 회전할 수 있도록 장착된 편심조정륜, 편심조정륜 둘레로 회전하는 편심작업륜, 작업륜과 조정륜에 부착된 기초판 사이에서 연장되는 스프링, 그리고 작업륜 상에 회전할 수 있도록 장착된 인장롤러를 포함하는 탄력적으로 조정가능한 인장장치가 제공되며, 두 편심륜의 상대적 가 위치조정이 표시기 수단에 의해 용이하게 되고, 편심조정륜이 기초판에 대하여 회전할 수 있고, 그리고 기초판과 고정된 모터블럭이 편심조정륜이 함께 기초판이 회전운동하는 것을 막기 위해 상호 맞물림 수단을 갖는다. 이같은 장치에서, 기초판과 따라서 그 속에서 고정되어 있는 스프링은 조정과정중에도 수직으로는 이동하지 않게 된다. 장치를 고정시키는 것은 편심작업륜 기능과는 완전히 분리되고 연속되는 조립시에 그리고 상당한 길이의 오차가 구동벨트에서 발생되어 조정위치를 크게 변화시킨다 해도 표시기에 의해 확인된 위치에서 항상 같은 인장력이 보장된다.According to the present invention, an eccentric adjustment wheel mounted to rotate around a fixed bolt of a fixed support object, an eccentric work wheel rotating around the eccentric adjustment wheel, a spring extending between the work wheel and the base plate attached to the adjustment wheel, and work An elastically adjustable tensioning device including a tension roller mounted to rotate on a wheel is provided, the relative positioning of the two eccentric wheels being facilitated by the indicator means, and the eccentric adjustment wheels rotating relative to the base plate. And the base plate and the fixed motor block have interlocking means to prevent the base plate from rotating together with the eccentric adjustment wheel. In such a device, the base plate and thus the springs fixed therein do not move vertically during the adjustment process. Fixing the device is completely separate from the eccentric work wheel function and ensures the same tension at all times in subsequent assembly and at the position identified by the indicator, even if a significant length of error occurs in the drive belt to significantly change the adjustment position. .

또한, 서로에 대한 위치와는 무관하게 한 관찰점으로 간주되어서, 표시기는 모터블럭과 관련하여 항상 같은 위치에 있게 되며 따라서 보는 방향을 변경시키지 않고 다른 구성부품에 의하여 가리워질 위험없이 편리하게 사용될 수 있다.It is also regarded as an observation point irrespective of the position relative to each other so that the indicator is always in the same position with respect to the motor block and thus can be conveniently used without risk of being obscured by other components without changing the viewing direction have.

본 발명의 실시예를 첨부도면에 의하여 더 상세히 설명하면 다음과 같다.When explaining the embodiment of the present invention in more detail by the accompanying drawings as follows.

도면에 도시된 인장장치는 편심조정륜(1), 슬라이딩 베어링 부시(2)를 통해 편심조정륜상에서 회전하도록 배치되어 있는 편심작업륜(3) 그리고 편심작업륜상에서 회전할 수 있게 장착되어 있는 클램프 롤러(clamping roller)(4)로 구성되어 있다. 편심조정륜은 기초판(5) 상에 놓여 있고, 고정볼트(6) 둘레를 회전할 수 있으며, 고정볼트에 의해 모터블럭(7)에 고정될 수 있다. 코일(coil)스프링(8)은 일단부(9)에 의하여 편심작업륜(3)에 고정되어 있고, 또 다른 단부(10)에 의하여 기초판(5)에 고정되어 있다.The tensioning device shown in the drawing includes an eccentric adjustment wheel 1, an eccentric work wheel 3 which is arranged to rotate on the eccentric adjustment wheel via the sliding bearing bush 2, and a clamp roller which is rotatably mounted on the eccentric work wheel. clamping roller). The eccentric adjustment wheel is placed on the base plate 5, can rotate around the fixing bolt 6, and can be fixed to the motor block 7 by the fixing bolt. The coil spring 8 is fixed to the eccentric work wheel 3 by one end 9 and to the base plate 5 by another end 10.

기초판(5)은 제1도 및 제2도에 도시된 바와 같이, 방사상으로 연장되어 있고, 외측으로 구부러져서 모터블럭과 맞물리는 돌출부(11)가 제공되어 있다. 노치(12)는 하나의 표시기를 형성하며, 이 표시기는 편심작업륜(3) 상에 있는 방사성 혀모양부(tongue)(14)에 배치되어 있는 뾰족한 지침(13) 형태의 또 다른 표시기와 협동한다. 편심조정륜(1)은 제3도에 도시된 바와 같이, 축방향으로 기초판(5)과 결합되어 있으나, 자유로이 회전할 수 있다.The base plate 5 is provided with projections 11 which extend radially, as shown in FIGS. 1 and 2, which are bent outwardly to engage the motor block. The notch 12 forms an indicator, which cooperates with another indicator in the form of a pointed guide 13 disposed on a radioactive tongue 14 on the eccentric working wheel 3. do. As shown in FIG. 3, the eccentric adjustment wheel 1 is coupled to the base plate 5 in the axial direction, but may rotate freely.

본 발명 장치가 제2도에 도시된 바와 같이 구동벨트(15)에 팽팽하게 긴장되는데 고정볼트(6)가 약간 느슨해진다. 본 발명 장치는 편심조정륜(1) 내의 육각형 소켓(16)에 맞물리는 조절공구에 의해 구동벨트에 연결된 채로 회전된다. 편심조정륜(1)은 고정볼트(6) 둘레를 기초판(5) 내에서 회전하며, 기초판은 모터블럭(7)에 대하여 부동상태로 머물러 있는다. 제2도에서는 벨트(15)가 퍼져 있으나, 아직도 팽팽히 긴장되어 있지 아니한 위치에 있다. 이 위치에서는 코일스프링(8)이 아직도 이안되어 있으며, 노치(12)와 뾰족한 지침(13)의 표시기들이 서로 떨어져 있다.As the device of the present invention is tensioned with the drive belt 15 as shown in FIG. 2, the fixing bolt 6 is slightly loosened. The device of the present invention is rotated while being connected to the drive belt by an adjustment tool that engages the hexagonal socket 16 in the eccentric adjustment wheel 1. The eccentric adjustment wheel 1 rotates in the base plate 5 around the fixing bolt 6, and the base plate remains in a floating state with respect to the motor block 7. In FIG. 2, the belt 15 is spread, but is still in a position where it is not tense. In this position the coil spring 8 is still lanyard and the indicators of the notch 12 and the sharp guide 13 are separated from each other.

편심조정륜(1)을 화살표 방향으로 더 회전시키면 편심조정륜(1)을 향해서 편심작업륜(3)의 회전운동이 시작되고, 이에 의하여 코일스프링(8)이 긴장되어진다. 편심조정륜(1)은 2개의 표시기, 즉 노치(12)와 뾰조한 지침(13)이 맞겹쳐 일치하게 될 때까지 회전한다.When the eccentric adjustment wheel 1 is further rotated in the direction of the arrow, the rotational movement of the eccentric work wheel 3 is started toward the eccentric adjustment wheel 1, whereby the coil spring 8 is tensioned. The eccentric adjustment wheel 1 rotates until two indicators, namely the notch 12 and the sharp guide 13, overlap and coincide.

허용오차에 의해 발생된 비교적 긴 구동벨트(15)에 있어서는, 편심조정륜(1)을 화살표방향으로 더 회전시켜야 한다. 그러나, 이것은 편심조정륜(1)의 모든 가능한 위치에서 그리고 노치(12)와 뾰족한 지침(13)의 표시기들이 맞겹쳐져 일치하는때 편심작업륜(3)의 작동레버 아암에는 아무런 영향을 미치지 않는다. 기초판(5)는 본래 움직이지 아니하기 때문에, 노치(12) 그리고 조정이 있은 후 뾰족한 지침(13)은 조정된 위치에서 항시 동일한 위치에 있게 된다. 즉, 노치(12)와 뾰족한 지침(13)은 인장장치가 장착되어 있는 모터에 대하여 항상 같은 위치를 갖게 되며, 이는 운전자에 의해 관찰방향이 일정하게 유지되도록 함으로써 특히 모터 정면의 협소한 공간에서 다른 부품들로 인해 손으로 조작하는 처리를 가리는 경우 조정을 간단하게 하는 장점을 제공한다.In the relatively long drive belt 15 generated by the tolerance, the eccentric adjustment wheel 1 should be further rotated in the direction of the arrow. However, this has no effect on the actuating lever arm of the eccentric work wheel 3 at all possible positions of the eccentric adjustment wheel 1 and when the indicators of the notch 12 and the pointed guide 13 overlap and coincide. Since the base plate 5 is not inherently moving, the notch 12 and the pointed guide 13 after the adjustment are always in the same position in the adjusted position. In other words, the notch 12 and the pointed guide 13 always have the same position with respect to the motor on which the tensioning device is mounted, which allows the operator to keep the direction of observation constant, especially in a narrow space in front of the motor. The advantage of simplifying the adjustment is that the parts obscure the handling by hand.
