PUThe synchronous belt contains repeating carbamate groups on the main chain (NHCOO )A general term for macromolecular compounds of。PUThe synchronous belt uses teeth to mesh with the grooves of the pulley to transmit motion and power，It is a type of meshing transmission，Therefore, it has gear transmission、The Various Advantages of Chain Drive and Flat Belt Drive。High wear resistance，Ensure that it still maintains good mobility during transmission。Less tolerance。

SUNMGAThe synchronous belt can also be addedPU、Adding rubber（Black gum、White glue、Green glue、Red gum）、High temperature resistant rubber、Enhanced wear-resistant rubber、Various typesPVCConveyor belt、sponge（ordinarysponge、Hardness sponge、With clothsponge）、Synchronous belt front and back fabric、Punching、Milling and other deep processing。

PUInstallation method of synchronous belt：

1、Remove the old belt，Check for abnormal wear。 Wear may be due to issues with the design or maintenance of the transmission device。 Install polyurethane on the pulleyPUSynchronous belt time，In order to prevent the tensile layer in the synchronous belt from breaking，Do not use excessive force or pry with a screwdriver，To avoid being invisible from the appearance。

2、When installing the pulley，Select a structure with two axes that can move closer to each other。 If this structure is not allowed，Add polyurethanePUInstall the synchronous belt and pulley together on a suitable shaft。

3、When cleaning belts and pulleys，It is not advisable to use a small amount of cloth to wipe with a non volatile liquid，Soak in detergent or scrub the belt with detergent。

4、Remove oil stains、Stains，Wipe with sandpaper or sharp objects，Obviously not advisable。 polyurethanePUThe synchronous belt should be kept dry before installation and use。

PUThe synchronous belt has high flexibility、Shear strength and bending fatigue resistance，Not prone to aging，Has good wear resistance and oil resistance。 PUSynchronous belt is a fabric made by spirally winding multiple steel wire ropes along the width of the tape，And use its position as the pitch line of the synchronous belt。 The wire core can improve the strength and tensile strength of the tape，Ensure good dimensional stability of the tape。 The tensile layer has high tensile strength and bending fatigue strength。 High elastic modulus，Extension is not allowed during work，Ensure constant synchronous belt spacing。
