Audited Supplier The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the combined action of centrifugal force from rotating mass, periodic gas inertia force, and reciprocating inertia force, which causes the crankshaft to withstand bending and torsional loads. Therefore, it is required that the crankshaft has sufficient strength and stiffness, and the surface of the journal should be wear-resistant, work evenly, and have good balance. The most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the combined action of centrifugal force from rotating mass, periodic gas inertia force, and reciprocating inertia force, which causes the crankshaft to withstand bending and torsional loads. Therefore, it is required that the crankshaft has sufficient strength and stiffness, and the surface of the journal should be wear-resistant, work evenly, and have good balance. To reduce the mass of the crankshaft and the centrifugal force generated during movement, the crankshaft journal is often made hollow. There are oil holes on the surface of each journal to introduce or remove oil for lubrication of the journal surface. To reduce stress concentration, transition arc connections are used at the connections between the main journal, crank pin, and crank arm. The function of crankshaft counterweight (also known as counterweight) is to balance the rotating centrifugal force and its torque, and sometimes it can also balance the reciprocating inertial force and its torque. When these forces and moments themselves reach equilibrium, the counterweight can also be used to reduce the load on the main bearing. The number, size, and placement position of the counterweight should be considered based on factors such as the number of cylinders in the engine, cylinder arrangement, and crankshaft shape. The balance weight is generally cast or forged into a whole with the crankshaft, and the balance weight of high-power diesel engines is manufactured separately from the crankshaft and then connected together with bolts.
