Selection pulley which parameters need to require a total of four data 1, the choice of which belt (such as A, B, C) based on the torque select words on King size 2, you need to select a few belts torque is 3, according to the hole mounting shaft The diameter of 4, the outer diameter is calculated according to the desired speed example: general cutting machine motor driven wheel is a wheel capstan motor 2A 2A of natural selection is to measure 2 2.2 28 cutters need to enter the motor speed is 2800 rpm 2800 driven wheel 1 90: 1 is 90, then the capstan pulley for the complete model: 2A * 28 * 90 Considerations when a turn with the pulley, the pulley assembly before final cleaning must be used petrol to ensure that all parts clean and dry, in order to ensure close cooperation with the surface and free from grease sleeve pulley, there is enough friction. Little experience: 1, the current standard pulley pulley sleeve on the market, using the demolition Rama (especially hydraulic Rama) Pull always pull the broken edge portion of the pulley. In Rama's three claws at the sleeve pull pulley price, 5mm thick mat of long iron that increase the force area, can greatly reduce the possible damage the pulley. 2, the installation, you should look polished with fine gauze inside diameter pulley glitches, and then coated with a thin layer of grease sleeve pulley Which is best, so it is easier to install the pulley onto the shaft. 3, when the pulley to the motor shaft extension is installed, you should remove the hood, on top of the measuring shaft wall, and then tap into the shaft pulley. Otherwise, it is easy to cover motor side shattered, it may be a single-phase induction motor centrifugal switch smashed. 4, when the pulley on the motor can not be removed using a hydraulic puller, the rotor can be removed with a horizontal lathe removed the pulley, then buy new wheels installed.
