Installation and disassembly of belt pulley & nbsp;
설치 및 분해
설치
1. Check the pulley groove to ensure that there are no scratches or sharp edges, and all dimensions are in accordance with the standard;
2. Clean the surface of all parts, such as hub hole, taper sleeve, bolt hole, etc. Put the cone into the pulley to align all screw holes.
3. 나사 (TB 1008- TB 3030)와 나사산 (TB 3525- TB 5050)에 오일을 바르고 장착 구멍에 나사를 조이 되 아직 조이지 마십시오.
4. Clean the surface of the drive shaft, push the pulley with the tapered sleeve to the predetermined position on the shaft, and check whether the triangle pulley is aligned.
5. When the keyway is used, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub.
6. Use a hexagon wrench that conforms to the DIN911 standard, and gradually tighten the bolts in the mounting holes alternately and gradually until the torque shown in the following table is reached.
7. 짧은 작동 기간 (0. 5 ~ 1 시간) 후에 볼트의 조임 토크를 확인하고 필요한 경우 다시 - 조입니다.
8. In order to prevent the intrusion of foreign objects, fill the connecting hole of the hole with grease.
분해
1. Loosen all bolts, take out one or two bolts according to the number of disassembly holes, lubricate the bolt patterns and bolt tips with oil, and insert the bolts into the disassembly holes.
2. Tighten the bolts alternately until the taper sleeve and the pulley are loosened.
3. Remove the taper sleeve and pulley from the shaft.

풀리 조립시주의 사항
1. The last cleaning before assembly must use gasoline to ensure that the parts are clean and dry, to ensure that the mating surfaces are tightly matched, free of oil stains, and have sufficient friction.
2. 조립 용 육각 볼트도 조립 전에 휘발유로 세척하고 건조시켜야합니다. 볼트를 조인 후 충분한 마찰 자체 - 잠금 기능을 보장하기 위해 볼트 또는 나사 구멍에 윤활유 또는 그리스를 바르지 않아야합니다.
3. When the three hexagon socket head bolts are about to be installed in place, they need to be tightened in turn to ensure that the cone sleeve is evenly axially loaded and the pulley and cone sleeve are positioned coaxially.
4. 설치 전에 조립에 사용 된 육각 소켓 볼트의 길이를 확인하여 조립 볼트가 콘 슬리브의 막힌 구멍의 하단을 견딜 수 있는지 확인하고 콘 표면이 단단히 고정되도록하고 볼트가 노출되도록하십시오. 막힌 구멍의 하단 끝에서 추력을 역전시킵니다. 더블 너트 원리의 풀림 방지 효과는 동일합니다.
5. After the pulley is tightened, check the cable and adjust the relative position of the master and driven pulleys to ensure that the two pulleys are on the same plane and the belt tension is moderate.
6. The pulley cover should be intact and firmly installed to ensure that the belt breaks during operation or the pulley loosens and exits, resulting in a major safety accident. 7. The cone sleeve is a wearing part. After a long period of operation, the inner hole and the chain groove may be damaged. It should be checked before each assembly. If a defect is found, the spare part should be replaced in time.
작은 경험
1. For the pulleys currently on the market, use the puller (especially hydraulic puller) to pull out the edge part of the pulley when disassembling. At the 3 pull claws of the puller, a long 5mm thick iron plate can be placed to increase the force bearing area, which can greatly reduce the possibility of damage to the pulley.
2. When installing, you should first polish the burrs of the inner diameter of the pulley with fine gauze, and then apply a thin layer of grease to make it easier to install the pulley on the shaft.
3. 모터 샤프트에 풀리를 설치할 때 윈드 후드를 제거하고 측정 샤프트를 벽에 대고 누른 다음 풀리를 탭하여 샤프트에 들어갑니다. 그렇지 않으면 모터의 측면 덮개를 깰 수 있으며 단일 - 위상 비동기 모터의 원심 스위치가 파손될 수도 있습니다.
4. When the pulley on the motor cannot be removed using the hydraulic puller, the rotor can be removed, the pulley can be removed with a horizontal lathe, and a new pulley can be purchased for installation.
