PU timing belt drive is a new type drive mode by use belt teeth and belt gear in mesh to transmit the driving force Timing belt adopts the high quality polyurethane as its main raw, iterial and is compounded with other ingredients of different Actions according to the new formulation.Timing belt drive has accurate synchronization. it neednt Lubricate and features no slip. no contamination and little noise. its drive efficiency is up to O.98,The speed ratio range is large, that can reach1:10.The allowed line speed ratio range is large, that drive power is suitable to multiple shaft drive from several watts to hundreds of thousands of watts. PU timing belt has the following strong points: dynamic buckling resistance, crack resistance. good performance. excellent ozone performance, aging resistance, cold resistance, oil resistance and wear resistance, etc.PU timing belt is widely applied to the machines in textile, automobile, chemical fiber, cigarette, papermaking, printing and chemical industries. it has growing demands to be used in mining .,steel and iron machinery and medical equipment these years.
