Crankshaft in a car. How does the operation and design of the crankshaft look like?

crankshaft design
Are you curious about how the work, design and shape of the crankshaft looks like? We hasten to answer. The crankshaft consists of a number of complex elements:
- cones for landing pulleys;
- counterweights with fastening bolts;
- surface for sealing ring;
- diameters of cam gears, flywheels and auxiliary drives;
- oil hole plugs and crankpin drilling;
- slots for lock key;
- clutch shaft bearings;
- oil deflector plate.
Shaft in the machine - the work of the element
Parts of the crankshaft of the car must be manufactured with high precision and the use of materials that are resistant to mechanical damage and high temperatures and lubricants. Typically, the crankshaft in your car is the part of the drive that is driven by a group of pistons. This allows efficient transmission of torque to the flywheel. Then the gear racks and drive axles rotate. It is an integral part of any internal combustion engine. Its failure may lead to the need for a major overhaul of the cylinder block.
What are the symptoms of a damaged shaft in a car?
Rough engine running is one of the most common signs of engine failure. shaft in the car. A symptom indicating damage to the connecting rod may also be the impossibility of starting the drive after turning the key in the car's ignition or its extinction after warming up.
Crankshaft failure in a car - causes
The main reasons for the failure of the crankshaft can be:
- incorrect assembly;
- poor lubrication;
- a faulty sensor, often indicated by a "check engine" light.
Don't forget to have your car regularly inspected. The rotation of the crankshaft housing is one of the consequences of neglect in this regard. This can cause severe engine damage. Repair and overhaul of the engine is very expensive. To avoid this, you should regularly check the oil level and follow the intervals recommended by the car manufacturer between fluid changes. By taking care of the periodic inspection of the condition of the drive unit, you will save time and money that would have to be spent on repair measures.
Crankshaft repair - at home or at home?
Right the crankshaft in the car should not be carried out independently. The design of the crankshaft is very complex. Regeneration consists in precise machining, the purpose of which is to restore the physical parameters of the part in accordance with the catalog data for a given vehicle. Observe all perpendiculars and angles. All types of looseness are also eliminated. If there are gaps between the pin and the sleeve, replace individual parts.
It is also very important to carefully check the geometry of the crankshaft. Additional components may need to be rebuilt, such as the head, piston rings, or cylinder block. Often there is a situation in which repair is equivalent to an expensive overhaul of the drive. To perform the service, high qualifications and appropriate workshop equipment are required. It is better to entrust the repair of the crankshaft to a trusted car service.
How much does a crankshaft restoration cost?
You probably know that the level of complexity of the design of modern passenger cars is so high that every major breakdown is associated with considerable repair costs. The cost of professional crankshaft regeneration can range from several to several thousand PLN. Often there is a need for a major overhaul of the engine. Often the service is unprofitable. Then it remains only to hand over the car to the disassembly point.
If you want to prevent high costs, you should take care of regular self-inspection of the technical condition of the car. Necessary measures include checking the oil level, as well as a visual inspection to detect leaks of working fluids. Any malfunction of the vehicle, i.e. a problem with starting the engine or its uneven operation should prompt you to visit a diagnostician.
What is a crankshaft journal?
Elements of modern crankshafts are necks. With their help, the axis of rotation of the system is determined, and also placed on supports. Their design and number depend on the design of the drive unit, as well as on the location of the cylinders of a given engine model. Nowadays, the crankshaft journals also act as a support, ensuring the correct operation of the bearings during operation. The accuracy of their execution and location is important, therefore, during repair and regeneration, the accuracy of processing and compliance with the concentricity of the nests are important.
