PU synchronous belt transmission design and calculation. Synchronous belt transmission design and calculation is to choose the synchronous belt and pulley structure parameters of the main basis, to the attention of the countries synchronous belt manufacturer and user. In many companies in the standard are put forward their own design and the calculation method of choosing parameters of synchronous belt. 1 198 years between the international organization for standardization developed in step with tensile strength to the calculation method of design criterion ISO5295 - 1981 'synchronous belt power rating and the calculation of transmission center distance of the international standard. But when using this method, in which the benchmark rated power of synchronous belt ( May pull) Using the synchronous belt performance data provided by factory. In addition, the Soviet union scholars elder brother column, v, don't also, waiting for the failure form and calculation method of the synchronous belt for more in-depth research, put forward the synchronous belt abrasion resistance, shear strength and the transmission efficiency and so on the many kinds of calculation methods, and USES the limited. Element method to calculate the tooth stress distribution at work. The synchronous belt must not be stored chronically abnormal bending condition. 1, please keep in the shade. 2, when installation, please shorten the center distance or relaxing tension wheel, and then reset. Shall not be forced the synchronous belt driven wheel rim hard pull on the mill load. 3, installation of synchronous belt need to wheel tooth surface of the vertical line. 4, driving wheel and driven wheel spindle parallelism should be controlled in tg tangent theta = 1/1000. Shaft will not directly affect the service life. 5, belt running phenomenon is found, should be adjusted two axis parallelism or two rounds of axial location. And adjust the tension wheel pressure. 6, such as found jump tooth synchronous belt slack or phenomenon, should immediately check whether the center distance is correct or loose shift. Otherwise should adjust or reinforcement. 7, synchronous belt when installation, need according to different specifications and bandwidth, properly adjust the tension. 8, tension wheel must be installed at the side of the synchronous belt transmission with loose edge.
