Pulley works: belt drive are "flexible transmission" in the basic institutions of machinery - namely the use of skin connecting the two are not brought in direct contact with the active members and followers, the friction generated by the tension to transmit motion and power. 2. The difference: V-belt pulley power transmission applications: the role of bearing pulley in the passing of a long distance, in order to prevent the belt is too loose (or wrap angle is too small) from? ? Tightening effect, so called - tight round (round?); The pump can be used to determine the number of revolutions of the pulley diameter was needed on it. 3. The belt drive features: smooth, low noise, overload "slip" play a protective role to facilitate the production, simple maintenance for the center distance greater transfer sheave manufacturers | Bang Hong Machinery (certified) | sheave by Guangzhou State hung Machinery Limited.
