Installation and disassembly of belt pulley & nbsp;
Installation et démontage
installation
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. Appliquez de l'huile sur la vis (TB 1008- TB 3030) et le filetage (TB 3525- TB 5050) et vissez-la dans le trou de montage, mais ne la serrez pas encore.
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. Après une courte période de fonctionnement (0. 5 à 1 heure), vérifiez le couple de serrage des boulons et resserrez - si nécessaire.
8. In order to prevent the intrusion of foreign objects, fill the connecting hole of the hole with grease.
Démonter
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.
Précautions
Précautions pour l'assemblage de la poulie
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. Les boulons hexagonaux pour l'assemblage doivent également être nettoyés et séchés avec de l'essence avant l'assemblage. L'huile de lubrification ou la graisse ne doivent pas être appliquées sur les boulons ou les trous de vis pour assurer une capacité de blocage auto-- suffisante après le serrage des boulons.
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. Vérifiez la longueur des boulons à six pans creux utilisés pour l'assemblage avant l'installation pour vous assurer que les boulons d'assemblage peuvent résister à l'extrémité inférieure du trou borgne du manchon de cône pour assurer l'ajustement serré de la surface du cône et assurez-vous que le boulon est soumis pour inverser la poussée à l'extrémité inférieure du trou borgne. L'effet anti-desserrage - du principe du double écrou est le même.
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.
Petite expérience
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. Lors de l'installation d'une poulie sur l'arbre du moteur, la hotte doit être retirée, l'arbre de mesure doit être pressé contre le mur, puis appuyez sur la poulie pour entrer dans l'arbre. Sinon, il est facile de casser le capot latéral du moteur, et cela peut également casser l'interrupteur centrifuge du moteur asynchrone monophasé -.
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.
