Correct. It is more accurate than belt drive.
Correct. Features of chain drive: ① Compared to gear drives, it can transmit motion and power even when the centers of the two shafts are far apart; ② It can operate under conditions of low speed, heavy load, high temperature, as well as in harsh environments with dust and debris; ③ Compared to belt drives, it ensures an accurate constant transmission ratio, can transmit larger powers, and exerts less force on the shafts and bearings; ④ It has a high transmission efficiency, generally ranging from 0.95 to 0.97; ⑤ Wear of the chain links causes an increase in the pitch, which leads to chain detachment; ⑥ It requires higher standards for installation and maintenance. The material used for sprockets is usually structural steel
