Product Details

The company is a profession to promote dune buggy of accessories. Cfmoto 500cc crankshaft is an important part of truck engine parts, and it is also a fast moving parts. We have rich experience in product sales. Crankshaft is one of the most important and expensive parts in engine, its size has an obvious influence on size and weight, and to a great extend, on the reliability of engine. If you have any question, please contact with us!


The most important part of the engine. It takes the force from the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine. The crankshaft is subjected to a centrifugal force of a rotating mass, a cyclically varying gas inertial force, and a reciprocating inertial force to cause the crankshaft to undergo a bending torsional load. 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.


In order to reduce the mass of the crankshaft and the centrifugal force generated during the movement, the crankshaft journal is often made hollow. Oil holes are formed in each journal surface to introduce or withdraw oil to lubricate the journal surface. In order to reduce the stress concentration, the transition of the main journal, the crank pin and the crank arm is connected by a circular arc.


The function of the balance weight of the crankshaft (also called the counterweight) is to balance the centrifugal force and its torque, and sometimes to balance the reciprocating inertial force and its moment. When these forces and moments are themselves balanced, the counterweight can also be used to relieve the load on the main bearing. The number, size and placement of the counterweights should be considered based on factors such as the number of cylinders in the engine, the arrangement of the cylinders, and the shape of the crankshaft. The balance weight is generally integrated with the crankshaft casting or forging. The high-power diesel engine balance weight is manufactured separately from the crankshaft and then bolted together.

Q1. What type does it belong to ?

A: Engine rotating machine.

Q2. What is it used to?

A: It is used to form a power source.

Q3. What is the structure?

A: It consists of main journal and connecting rod neck.

Q4. How about the forging technology ?

A: The automatic line with hot forging press and electro-hydraulic hammer as the main engine is the development direction of forged crankshaft production. These production lines will generally adopt precision shearing, roll forging (cross wedge rolling), medium frequency induction heating, finishing hydraulic press. Advanced technology such as precision pressing, and equipped with a robot, conveyor belt, and a die changer with a rotary table to form a flexible manufacturing system (FMS).
