What is the main function of the crankshaft?
1 Answers
Detailed information about the function of the crankshaft counterweight is introduced as follows: 1. The function of the crankshaft counterweight is to balance the rotational centrifugal force and its moment. The purpose is to reduce the vibration amplitude and frequency after the crankshaft rotates at high speed. 2. When the force and moment themselves reach balance, the counterweight is used to reduce the load on the main bearing. 3. The number, size, and placement position of the counterweights should be considered based on factors such as the number of engine cylinders, cylinder arrangement, and crankshaft shape. 4. Counterweights are generally cast or forged as an integral part of the crankshaft. In high-power diesel engines, the counterweights are manufactured separately from the crankshaft and then bolted together.
