　　Product classification: trapezoidal double-sided teeth synchronous belt -DL synchronous belt series
　　Product description: rubber trapezoid double layer tooth synchronous belt of the belt 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. In addition, the polyurethane is the double-sided tape of the material. The products have the characteristics of dynamic flexion, good anti-cracking, good ozone performance, aging resistance, heat resistance, oil resistance and wear resistance. The model of trapezoid double-sided synchronous belt includes: XL, L, H, XH, XH, XXH, T2.5, T5, T10, T20, AT5, AT10, AT20, etc.

　　1、It is strictly forbidden to fracture, bend, avoid strong layer damage and lose the use value.
　　2、It is not allowed to store the DL double tooth synchronous belt in an abnormal bending state.
　　3、Keep the DL double sync zone in the shade.
　　4、When installing, please shorten the center distance and relax the tensioning wheel. It is not allowed to force drag and drag from the bottom of the belt wheel.
　　5、The tooth of the DL 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、It is found that on the active wheel, the DL double-sided tooth synchronous belt is shifted to one side, the passive wheel should be adjusted and the pressure of the tensioning wheel should be adjusted.
　　8、At the start, the center is changed, the DL double tooth synchronous belt relaxation, the occurrence of jumping tooth phenomenon, should check whether the belt wheel frame is loose, and the positioning of the shaft is not accurate. Adjust and reinforce.
　　9、DL double - double tooth 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.

　　Synchronous belt transmission is a new belt transmission 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, the increasing demand, synchronous belt transmission is now in a variety of instruments, computer, sewing machines, textile machines, chemical fiber is widely used in machine, and other general machinery.
