What are the advantages and disadvantages of chain drive and synchronous belt pulley?
Advantages: 1., constant transmission ratio;2. compact structure;3., because of the thin and light, high tensile strength, so belt speed up to 40 m/s, transmission ratio of 10, transmission power of up to 200 KW;4. high efficiency, up to 0.98.Characteristics and application of chain driveIt consists of chain wheel and ring chainFunction: the meshing between chain and sprocket teeth is driven by the same direction between parallel shafts.
The structure features: the cross section is rectangular, and the belt with a mask with isometric transverse teeth is used, and the synchronous belt wheel face is also made into a corresponding tooth shape.Transmission characteristics: the synchronous belt teeth and synchronous belt meshing between the teeth to drive, the two without relative slip, and make the circle speed synchronization, so called synchronous belt drive.
Characteristics and application of synchronous belt driveThe synchronous belt drive is usually composed of driving wheel, driven wheel and belt which is tightly sheathed on two wheels.Work principle: the use of intermediate flexible parts (belts), by friction (or meshing) between the main and driven shafts to transfer rotational motion and power.Composition: synchronous belt (synchronous toothed belt) is made of steel wire as tensile material and polyurethane or rubber is wrapped.
