The characteristics of synchronous belt

(2) Smooth transmission, with buffering and vibration reduction capabilities, and low noise

(3) The transmission efficiency is high, up to 0.98, and the energy saving effect is obvious

(4) Convenient maintenance, no lubrication, low maintenance cost

(5) The speed ratio range is large, generally up to 10, and the linear speed can reach 50m/s, with a large power transmission range, up to several watts to several hundred kilowatts

(6) can be used for long-distance transmission, the center distance can reach more than 10m

3. Main failure modes of synchronous belt drive

①Band body fatigue fracture

②Shear and crush with teeth

③The belt side, belt teeth are worn, and the wrapper peels off

④The load-bearing layer is elongated, the pitch is increased, the interference of the teeth is formed, and the teeth are crawling

⑤The belt body is broken by impact and overload
