구동장치용 부하 시험 장치Load test device for drive
본 발명은 구동장치용 부하 시험 장치에 관한 것으로, 보다 상세하게는 토크리플 발생이 최소화되어 정밀도가 개선되는 구동장치용 부하 시험 장치에 관한 것이다.The present invention relates to a load testing device for a driving device, and more particularly, to a load testing device for a driving device in which the occurrence of torque ripple is minimized and the precision is improved.
일반적으로 모터 또는 발전기의 성능 시험시 온도, 습도 등의 환경 시험을 위해 검사용 챔버가 사용된다. 이때, 모터 또는 발전기는 다양한 산업현장에 사용되는데 고정밀도가 요구되는 산업에 적용하기 위해 검사 단계에서 정밀한 검사가 수행되어야 한다. In general, an inspection chamber is used for environmental tests such as temperature and humidity during performance testing of motors or generators. At this time, the motor or generator is used in various industrial sites, and in order to apply it to an industry that requires high precision, a precise inspection must be performed in the inspection stage.
여기서, 종래의 모터 또는 발전기의 검사방식은 검사용 모터를 준비하고, 검사용 모터의 축에 검사대상 모터를 연결한다. 그리고, 내부에 공간이 형성된 챔버를 상기 검사대상 모터로 이동시켜 상기 검사대상 모터가 상기 챔버 내부 공간에 배치된 상태에서 검사가 수행되었다. Here, in the conventional inspection method of a motor or generator, a motor for inspection is prepared, and a motor to be inspected is connected to the shaft of the motor for inspection. Then, the inspection was performed in a state in which the chamber having a space formed therein was moved to the motor to be inspected, and the motor to be inspected was disposed in the space inside the chamber.
이때, 상기 검사용 모터는 상기 챔버의 외부에 배치되어 상기 검사용 모터와 상기 검사대상 모터 사이에 연결되는 축 또한 외부로 노출 배치된다. 그리고, 상기 검사대상 모터가 상기 챔버에 의해 외부와 단열 밀폐 및 차단된 상태에서 항온, 항습에 따른 환경 시험 등이 수행되었다. In this case, the motor for inspection is disposed outside the chamber, and a shaft connected between the motor for inspection and the motor to be inspected is also exposed to the outside. In addition, an environmental test according to constant temperature and humidity was performed in a state in which the motor to be inspected was thermally sealed and blocked from the outside by the chamber.
그리고, 상기 검사용 모터와 상기 검사대상 모터 사이에는 동력 전달을 위한 커플링이 사용된다. 이러한 상기 커플링은 디스크 타입, 올댐 타입, 또는 죠 타입으로 구비될 수 있으며 금속 재질, 우레탄 등의 재질로서 구비되어 축의 오정렬을 완충시킬 수 있다. In addition, a coupling for power transmission is used between the inspection motor and the inspection target motor. The coupling may be provided as a disk type, an Oldham type, or a jaw type, and may be provided as a material such as a metal material or urethane to cushion the misalignment of the shaft.
여기서, 상기 검사용 모터가 구동됨에 따라 상기 커플링을 통해 동력 연결된 상기 검사대상 모터가 연동되어 회전될 수 있다. 이때, 상기 커플링의 각 타입마다 완충력이 상이하여 각각의 비틀림강성을 가지고 있다.Here, as the inspection motor is driven, the inspection target motor, which is powered through the coupling, may be interlocked and rotated. At this time, the cushioning force is different for each type of coupling, and thus each type of coupling has torsional rigidity.
그러나, 커플링의 비틀림강성이 강하면 토크전달력이 뛰어나지만 토크리플 성분까지 전달하는 문제점이 있었다. 그리고, 토크리플 성분이 전달되면 토크리플 성분을 억제해야 하는 응용분야에서 사용하기 어려운 문제점이 있었다.However, when the torsional rigidity of the coupling is strong, the torque transmission power is excellent, but there is a problem in that it transmits even the torque ripple component. And, when the torque ripple component is transmitted, there is a problem in that it is difficult to use in the application field in which the torque ripple component must be suppressed.
이에 따라, 비틀림강성이 강하면서 토크리플 성분의 전달이 최소화되기 위한 커플링의 개발이 요구되고 있다. Accordingly, the development of a coupling for minimizing the transmission of torque ripple components while having strong torsional rigidity is required.
상기와 같은 문제점을 해결하기 위하여, 본 발명은 토크리플 발생이 최소화되어 검사정밀도가 개선되는 구동장치용 부하 시험 장치를 제공하는 것을 해결과제로 한다.In order to solve the above problems, an object of the present invention is to provide a load testing apparatus for a driving device in which the occurrence of torque ripple is minimized and the inspection accuracy is improved.

상기의 해결 수단을 통해서, 본 발명은 다음과 같은 효과를 제공한다. Through the above solutions, the present invention provides the following effects.
첫째, 검사축부가 삽입되는 제1링부와, 검사대상 구동장치의 회전축이 삽입되되 제1링부와 전후방향으로 이격된 제2링부의 각 외주면에 유기적 운동이 가능한 적어도 한겹 이상의 탄소섬유 직조체 권취물로서 구비되는 회전전달부의 양단부가 결합되므로 회전력 전달시 축정렬 불량으로 인한 장비 파손이 예방되어 내구성이 개선될 수 있다. First, the first ring part into which the inspection shaft part is inserted, and the rotation shaft of the driving device to be inspected is inserted, the first ring part and the second ring part spaced apart in the front-rear direction on each outer peripheral surface of at least one layer of carbon fiber woven body windings capable of organic movement Since both ends of the rotation transmission unit provided as a rotation transmission unit are combined, damage to equipment due to shaft misalignment is prevented during transmission of rotational force, and durability can be improved.
둘째, 제1링부가 회전되면 회전전달부의 일측이 회전방향을 따라 1차 회전되어 비틀린 상태에서 회전전달부의 타측이 2차 연동 회전되며 제2링부에 회전력을 전달하는 유기적 운동을 통해 토크리플이 보정 및 완화되어 환경 시험시 도출되는 검사대상 구동장치의 성능데이터의 정확도 및 신뢰도가 현저히 개선될 수 있다.Second, when the first ring part is rotated, one side of the rotation transmission unit is rotated first along the rotational direction, and the other side of the rotation transmission unit is rotated in a second interlocking state in a twisted state, and torque ripple is corrected through an organic movement that transmits the rotational force to the second ring unit. And, by being relaxed, the accuracy and reliability of the performance data of the driving device to be inspected derived during the environmental test can be significantly improved.
셋째, 제1링부에서 제2링부로 전달되는 회전력의 허용최대치를 초과하는 외력이 작용하는 경우 탄소섬유 직조체 권취물로서 구비된 회전전달부가 파단됨에 따라 회전력의 전달이 신속하게 차단되므로 검사구동부와 검사대상 구동장치의 파손이 미연에 방지되어 사용안전성이 현저히 개선될 수 있다. Third, when an external force exceeding the allowable maximum value of the rotational force transmitted from the first ring part to the second ring part acts, the rotational transmission part provided as a winding of carbon fiber woven body is broken, so that the transmission of the rotational force is quickly blocked, so the inspection driving part and The damage of the driving device to be inspected is prevented in advance, and the safety of use can be significantly improved.
넷째, 전달가능한 회전력의 허용최대치에 대응하여 탄소섬유 직조체 권취물이 적어도 한겹 이상 제1링부 및 제2링부의 외주면에 반경방향을 따라 적층된 상태에서 열가압장치를 통해 원주방향을 따라 반경방향 내측으로 가압 및 가열되어 용융 결합되어 전달하고자 하는 토크전달력의 정밀한 설정이 가능하므로 제조정밀성이 현저히 개선될 수 있다.Fourth, in a state in which the carbon fiber woven body windings are laminated along the radial direction on the outer peripheral surfaces of the first ring part and the second ring part at least one layer in response to the maximum allowable rotational force that can be transmitted, the radial direction along the circumferential direction through the hot pressing device It is pressurized and heated to the inside and melt-bonded to enable precise setting of the torque transmission force to be transmitted, so that manufacturing precision can be remarkably improved.

또한, 피검사물 설치를 위해 챔버 전체를 분리하던 종래와 달리, 상기 안착부(21) 및 상기 검사테이블(22) 사이에 배치된 상기 수직격벽부(31)에 관통 형성된 상기 관통홀(31a)에 상기 검사축부(11)에 동력 연결되는 상기 스핀들(14)이 회전 가능하게 관통 삽입배치된 상태로 준비된다. 따라서, 상기 밀폐커버(40)가 상기 메인챔버(30)로부터 분리된 상태에서 상기 검사대상 구동장치를 상기 검사테이블(22)의 상면에 배치하여 상기 스핀들(14)에 동력 연결하는 것만으로 검사를 위한 설치 준비가 완료되므로 검사편의성이 현저히 개선될 수 있다.In addition, unlike the prior art in which the entire chamber is separated for installation of an object to be inspected, in the through hole 31a formed through the vertical partition wall 31 disposed between the seating portion 21 and the inspection table 22 The spindle 14, which is power-connected to the inspection shaft 11, is prepared in a rotatably inserted state. Therefore, in a state in which the sealing cover 40 is separated from the main chamber 30, the inspection target driving device is placed on the upper surface of the inspection table 22 and the inspection can be performed only by power-connecting it to the spindle 14. As the installation preparation is completed, the inspection convenience can be significantly improved.
더욱이, 상기 검사구동부(10)의 검사축부(11), 토크센서(13), 스핀들(14) 및 상기 커플링부(50)의 축 정렬상태가 반복 검사시에도 유지되므로 축 정렬에 대한 검사정확도가 현저히 개선될 수 있다. Moreover, since the axial alignment state of the inspection shaft part 11, the torque sensor 13, the spindle 14, and the coupling part 50 of the inspection driving part 10 is maintained even during repeated inspection, the inspection accuracy for the axial alignment is improved. can be significantly improved.
