National standard pulley models are there? National standards for the V-belt models are O, A, B, C, D, E, F seven models, the corresponding groove pulley wheel angle, there are three 34 °, 36 °, 38 °, each model also provides the Triangle The minimum diameter of each wheel with corresponding small pulley groove angle, large pulley is not specified. Pulley often noisy how to do? In recent Bushes manufacturers, industrial production system developed to date, has gradually matured, various types of machinery and equipment have been able to achieve application integration operations, so machinery can only be more and more. Timing Pulleys are all kinds of machinery and equipment necessary for the transmission equipment Bushes, along with soaring demand spz Bushes, often there will be more problems in the application process, where noise pollution is a belt round can not be overlooked problem. You need to solve it? 1. In comparison with ordinary equipment, just from belt use part of the sound source to proceed round, due to the requirements of the transmission equipment for the belt round type and size are different, so in order to avoid excessive friction and noise, you must choose a high-precision timing belt pulleys products, but also in the design specifications meet the appropriate standards of production. 2. Timing Pulleys often also links the transmission belt, so their requirements for high tension coefficient must Bushes price, if the tension does not meet the needs of the intensity of transmission and will produce stretch, causing the noise source, with a reasonable belt This step is very important. 3. Timing Pulleys noise it can not be removed, you can install enclosures necessity. Bushes Standard | Bushes | Hengda machinery provided by the Texas Hengda Machinery Co., Ltd ..
