Polyurethane synchronous belt back for bonding and wrapping tensile components，It should have good flexibility and bending fatigue resistance，Not prone to aging，Good oil resistance，wear resistant，There are pointed grooves of appropriate size on the inner surface of the back of the polyurethane synchronous belt，In addition to process requirements，It can also improve the bending fatigue performance of the toothed belt，Simultaneously allowing the trapped air between the belt and teeth to escape during operation，To reduce some noise。

Characteristics of polyurethane synchronous belt

1、The tensile layer is the tensile component of the synchronous belt，Used to transmit power，Ensure that the synchronous belt maintains the same pitch during operation。Using multi-stranded steel wire rope(Or polyester cord)Spiral wound along the width of the tape，The position is the pitch line of the synchronous belt。The tensile layer must have high tensile strength and bending fatigue strength。Large elastic modulus，No extension allowed during operation，To ensure that the pitch of the synchronous belt remains unchanged。2、The teeth of the polyurethane synchronous belt should have high shear strength、Goodwear resistantResistance and oil resistance。High requirements for pitch distribution with teeth，The belt teeth should engage correctly with the groove of the belt wheel teeth，Therefore, there is a high requirement for the correctness of the geometric parameters of the belt teeth。polyurethaneSynchronous beltWith its excellent oil resistance andwear resistantKnown for sex。Suitable for medium to small power high-speed operation occasions。The environment should be relatively dry，The working temperature is generally-20~+80C。

3、The polyurethane synchronous belt is produced through a special molding process。

4、polyurethaneThe material makes the belt havewear resistantSexual and tear resistance。Steel wire core increases belt strength and tensile strength，Ensure good dimensional stability of the belt。

5、Polyurethane synchronous belt with small tolerance，Can ensure the accuracy of thickness and length。

Polyurethane synchronous belt, also known asPUSynchronous belt，It is composed of thermoplastic polyurethane and high-strength steel wire。ThermoplasticnaturepolyurethaneHaving highwear resistantnature，And various types of wire cores can ensure that they can still maintain good mobility during transmission，Its production tolerance is small。Open mouthedPUSynchronous beltReliable transmission，Dimensional stability。During the production process，Add a layer of nylon on the tooth surface or back，To ensure that the specificity of operations in special applications remains unchanged。A thick layer of polyurethane can be added to the back of the belt，To prevent high corrosion or high loads from occurring。

polyurethaneSynchronous belt：PolyurethaneSynchronous beltUsually made of nylon thread(Or steel wire、Copper wire)As a tensile body，Made by pouring polyester，Has oil resistance、Impact resistance、Features such as aesthetics。
