The rubber synchronous belt is made of glass fiber core，A rope composed of multiple glass fibers，Spiral distribution along the bandwidth at the nodal line position，High strength、Low elongation、Strong corrosion resistance。 Rubber synchronous with nylon sheath protective tape，Excellent wear resistance。 Hydrolysis resistance、Heat resistance、Superior impact resistancePUSynchronous belt，Wide transmission power range，Especially for high-power transmission，yesPUSynchronous beltWith incomparable，that，Let's take a look togetherPUSynchronous beltAnd rubberSynchronous beltWhat are the differences!

  PUSynchronous beltyesIntegrated belt drive、Chain drive、Products designed for the advantages of gear transmission。 according toSynchronous beltFriction transmissionofprinciple，Synchronous beltMust be tensioned before it can function properly。 Belt may become loose during operation。 To ensure thatSynchronous beltofability，For normal operation，To re tension。

  PUSynchronous beltTransmission with belt transmission、Advantages of Chain Drive and Gear Drive。 Due to synchronous belt transmissionyesBelt and pulley mesh to transmit motion and power，So there is no relative sliding between the belt and pulley，Can ensure accurate transmission ratio。 Synchronous beltUsually, steel wire rope or fiberglass rope is used as the tensile material，Chlorobutadiene or polyurethane as matrix，The belt is thin and light，Fast usage speed。

  butyes，Everyone should knowofyes，popularSynchronous beltofThe tension is basically the same，Divided into internal tension and external tension。 generally speaking，Suggest prioritizing the use of synchronous wheels for internal tension，And notyesLight pulley。 Because using smooth wheels increases noise and wear。 meanwhile，The diameter of the tensioning timing wheel cannot be smaller than the diameter of the small wheel。

  butyes，Some suppliers can also use inner tensioned toothed flat idlers，premiseyesRequires a diameter of40timesmore thanofBelt pitch。 in addition，Due to the decrease in inner tension, the wrap angle will be reduced，Reduce the number of effective meshing teeth，So in order not to make the wrap angle too small，Need to make the inner tension wheel as close to the main wheel as possible。 On the other hand，NingboSynchronous beltOuter tension。 Tensioning pulley in contact with the back of the belt，So there's no need for teeth，Smooth rollers are enough。 butyes，whetheryesTensioning the inner sideyesTensioning the outer side，The tensioning pulley needs to be placed on the loose side。 such，The difference in softness between the loose side and the loose side should not be too large at the beginning，The possibility of jumping teeth also decreases。
