The main reasons for dynamic loads generated by chain sprockets and chain drives during operation are
(1) The chain speed and the angular velocity of the driven sprocket change periodically, thus generating additional dynamic loads. The greater the acceleration of the chain, the greater the dynamic load will be. As can be seen, the higher the rotational speed of the sprocket, the larger the pitch of the chain and the smaller the number of teeth of the sprocket, the dynamic load will increase. (2) The velocity of the chain along the vertical direction also changes periodically, which makes the chain vibrate transversely, and this is also one of the reasons for the dynamic load of chain transmission. (3) When the chain link enters the sprocket, the chain link and the sprocket...
