Product classification: round - tooth rubber synchronous belt -S4.5M synchronous belt series
　　Product introduction: compared with trapezoidal tooth synchronous belt, and small tooth root stress concentration, longer life transmitted power than 1.2 2 times the depth of ladder type, and the synchronous gear is better, drive back and forth in the process of clearance is very small. Product belt layer is manufactured quality neoprene raw materials imported from Japan, skeleton layer is high quality glass fiber cord is imported from Japan, adopting high tooth surface wear-resisting layer adopts nylon 66 / do protection. The products include: 2M, 3M, 5M, 8M, 14M, 20M, S2M, S3M, S5M, S5M, S8M, S14M, RPP2M, RPP3M and other models.
　　1，It is strictly forbidden to break the S4.5M synchronously, bend it, avoid the damage of the powerful layer, and lose the value of use.
　　2，The S4.5M synchronous belt must not be stored in an abnormal bending state.
　　3，Keep the S4.5M synchronous belt in the shade to avoid direct sunlight, so that the synchronous belt can age easily.
　　4，During installation, please shorten the center distance, relax the tension wheel, and not force the belt to be loaded from the bottom of the belt wheel.
　　5，The teeth of the S4.5M synchronous belt wheel must be at a right Angle to the running direction.
　　6，The parallel degree of the main axis of the active wheel and the passive wheel is controlled at the tangent = 1/1000. No axial position can directly affect the 　　　service life.
　　7，Find that the S4.5M synchronous belt on the active wheel is sideways to one side. It should move the passive wheel to adjust and adjust the pressure of the tensioning 　　　wheel.
　　8，When starting up, the center is changed, and the S4.5M synchronous belt loosens. The jumping tooth phenomenon should be checked if the wheel frame is loose and 　　　the positioning of the axle is inaccurate. Adjust and reinforce.
　　9，The S4.5M synchronous belt installation must be properly tensioning with different models and bandwidths.
　　10，The tensioning wheel must be mounted on the side of the driving loose side.
　　The synchronous belt drive is a new belt drive which combines the advantages of belt drive, chain drive and gear transmission. Due to work like tooth shape, tooth of the pulley meshing transmission, and by the load on the tensile layer, to maintain with constant pitch line length, so there is no relative sliding between band and pulley, so that the main, driven wheel can do no slip between synchronous transmission. The speed range of synchronous belt transmission ranges from several revolutions per minute to the linear speed of 40m/s, the speed ratio can reach 10, the transmission efficiency can reach 99%, and the transmission power can range from a few watts to hundreds of watts. In recent years, mining, metallurgy, iron and steel machinery, medical equipment demand increasing, synchronous belt transmission is now in a variety of instruments, computer, sewing machines, textile machines, chemical fiber machine, and other widely used in general machinery.
