Brief description
Engine part 1103, suitable for Perkins ZZ90078110 series 3-cylinder cast iron crankshaft. We can provide good quality and price, welcome friends at home and abroad to consult and order. A complete after-sales system can help you solve problems in sales.
In order to reduce the mass of the crankshaft and the centrifugal force generated during movement, the crankshaft journal is often made hollow. Oil holes are formed on each journal surface to facilitate the introduction or extraction of engine oil to lubricate the journal surface. In order to reduce the stress concentration, the joints of the main journal, crank pin and crank arm are all connected by transition arc.
The function of the crankshaft counterweight (also called 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 are balanced by themselves, the counterweight can also be used to reduce the load on the main bearing. The number, size and placement of the counterweight should be considered according to factors such as the number of cylinders of the engine, cylinder arrangement and crankshaft shape. The counterweight is generally integrated with the crankshaft by casting or forging. The high-power diesel engine counterweight is manufactured separately from the crankshaft and then bolted together.
The crankshaft is the most important component in the engine. It withstands the force transmitted by the connecting rod and converts it into torque output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, which makes the crank bearing subjected to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.
