WEICHAI engine WD615 crankshaft 61560020029

Description

Work principle and introduction of the crankshaft 61560020029 of WEICHAI engine WD615:

The WEICHAI engine WD615 crankshaft 61560020029 is a key component in the WEICHAI engine system. Its main function is to convert the power brought by the connecting rod into torque and drive other components of the engine to rotate. Due to the strong centrifugal force and inertia acting on the crankshaft during its operation, the engine crankshaft requires high-quality materials.

Materials of the WD615 engine system crankshaft 61560020029:

The SINOTRUCK HOWO crankshaft of heavy truck engine system are generally composed of forged steel, cast iron, and alloy steel.

Forged steel depends on the quality of the steel itself and the processing technology. The better the quality of the steel used, the higher the quality. Forged ductile iron requires nitriding treatment to enhance strength and hardness. Alloy steel is composed of high-strength alloys and is widely used in engine crankshafts.

The construction of WEICHAI WD615 engine crankshaft 61560020029:

1. Main journal: Located at the center of the crankshaft, it is the component used to install the piston connecting rod, and it installs the shaft in the main bearing seat of the engine. It rotates through bearings (sliding bearings or rolling bearings).
2. Crank arm: Links the main journal and the balance block or flywheel as the connection point.
3. Balance block: Balances centrifugal force and torque, plays a role in maintaining stability, and eliminates vibration and noise during engine operation.
4. Front section and rear section: It installs timing gears, fans, water pumps, and belt pulleys, etc. The rear section links the flywheel, and through the flywheel, the power is transmitted to the clutchsystemor gearbox system.
5. Oil passage: The crankshaftbearingis machined with a through oil passage inside, used to convey lubricating oil to each bearing and friction surface, achieving lubrication and heat dissipation.

Engine system crankshaft fault 61560020029:

1. Engine performance deteriorates. It may be caused by the damage of the crankshaft.
2. Vibration and noise. When the crankshaft assembly is damaged, it often accompanies noise and vibration, usually manifested as metallic knocking sounds, friction sounds.
3. Crankshaft fracture is also a common fault. Generally, it is caused by the deviation of the axis line of the main journal, the relaxation of the flywheel, etc.

How to choose the engine crankshaft 61560020029? The selection of the crankshaft can be based on the sound ratio. Generally, if there is an echo after a knock, it is a steel crankshaft; if the sound is dull after a knock, it is a cast iron crankshaft.

The crankshafts produced by ZK TRUCK Company are all made of steel, and their hardness and toughness meet the national testing standards. The manufacturing accuracy and process of the crankshafts directly affect the service life of the entire engine system. We have even more stringent requirements for the crankshaft bearings. The exquisite craftsmanship and strict quality inspection and control system have won the favor of SINOTRUCK HOWO heavy trucks. For many years, ZK truck spare parts have been the OEM factory for SINOTRUCK GROUP. The professional and efficient services of ZK have promoted the application of China’s heavy truck parts worldwide.
