Installation and disassembly of belt pulley & nbsp;
Inštalácia a demontáž
inštalácia
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. Na skrutku (TB 1008- TB 3030) a závit (TB 3525- TB 5050) naneste olej a zaskrutkujte ho do montážneho otvoru, ale ešte ho neutiahnite.
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. Po krátkej dobe prevádzky (0. 5 až 1 hodina) skontrolujte uťahovací moment skrutiek av prípade potreby ho znova utiahnite -.
8. In order to prevent the intrusion of foreign objects, fill the connecting hole of the hole with grease.
demontáž
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.
Prevencia
Preventívne opatrenia pri montáži kladky
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. Šesťhranné skrutky pre montáž je potrebné pred montážou vyčistiť a vysušiť benzínom. Na skrutky alebo otvory na skrutky by sa nemal nanášať mazací olej alebo mazivo, aby sa zaistilo dostatočné samočinné zaistenie trením - po utiahnutí skrutiek.
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. Pred inštaláciou skontrolujte dĺžku šesťhranných skrutiek použitých na montáž, aby ste sa uistili, že montážne skrutky vydržia spodný koniec slepého otvoru objímky kužeľa, aby sa zaistilo tesné dosadnutie povrchu kužeľa a aby bola skrutka vystavená. obrátiť ťah na spodný koniec slepej diery. Anti - účinok uvoľnenia zásady dvojitého orechu je rovnaký.
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.
Malé skúsenosti
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. Pri inštalácii remenice na hriadeľ motora by sa malo odstrániť veko vetra, merací hriadeľ by sa mal pritlačiť na stenu a potom ťuknutím na kladku vstúpiť do hriadeľa. V opačnom prípade je ľahké rozbiť bočný kryt motora a môže tiež zlomiť odstredivý spínač jedného - fázového asynchrónneho motora.
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.
