Note that the choice of the pulley belt round two aspects are currently widely used in industrial and machinery production among the components will directly affect the quality of the entire production is carried out smoothly. So the choice of quality products and it is very important. Xiaobian to introduce the following when selecting belt round about the need to pay attention to two aspects. Select Timing Pulleys note the following two aspects: first, some people in the choice of products may vary depending on the motor power as the basis for selection, in fact, seven or eight of the pulley is not much difference, so choose When purchasing power does not determine the quality of the product. Consumers should be considered in the process of buying the width of the pulley, alternator pulley is usually the best choice for the width of 14 meters, if you want to make it the width increases, the intensity of the reference range may exert a certain intensity can a. Second, consumers in the purchase should be noted that businesses may recommend that you choose 8 m models timing belt pulleys, then you should be careful, the engine power is usually the device is about 300,000 watts, so the motor is applied Torque is generally greater, 8 m models generally only afford 70KP pulley torque, but in order to make the pulley to work, it must be obtained before they can withstand 100KP torque, so eight meters wheeled models will not be available for consumption to buy. These are optional when the timing belt pulleys to note describes two aspects, we hope to be able to buy via the above understanding of knowledge, the knowledge of the above apply to live in large Bushes, so as to buy out their own a satisfactory product. Bushes installation techniques introduced Bushes drive has run smoothly, can ease the impact load, low noise, low vibration, simple structure, low cost, easy maintenance, good flexibility and elasticity, overload protection can slip shaft center distance adjustment range, no lubrication and so on. When installing the disassembly easier, since there are more loose pulley during operation, installation requirements are higher Bushes, from the shaft hole to the belt groove as a whole, when you install the shaft bore and shaft interference fit to ensure that they meet close axial sliding does not occur with the flat key connection to the drive. Because there is a big interference Bushes Bushes manufacturers offer to the pulley mounting and dismounting of great difficulty spz Bushes, in practice, often due to the need to install and remove damaged pulley percussion, while extending the installation time, resulting in spare parts and maintenance, installation costs increase equipment uptime prolonged recovery and other shortcomings. Bushes, is the separation of the traditional part of the belt and pulley shaft hole section into two parts, by the inner cone pulley and shaft hole (outer cone sleeve) integrally connected with the outer cone, drogue open radial slot, can be changed to facilitate circumferential diameter drogue under pressure or tension. After installation, the inner pulley cone and outer cone against the inner sleeve junction hex bolts clamping mating surfaces to form a whole, works and traditional pulley is no different.
