The role of crankshaft oil seal

It is a key component of a vehicle or mechanical engine. It is responsible for preventing oil from leaking out of the engine and preventing dirt, dust and other contaminants from entering the engine.

Crankshaft oil seals are a critical component of a vehicle or mechanical engine and play a vital role in preventing oil leaks and engine damage. Regular maintenance and replacement of this part helps ensure the longevity and performance of the engine
Crankshaft oil seal sealing principle: 1. Because there is an oil film controlled by the edge of the oil seal between the oil seal and the shaft, the oil film has fluid lubrication characteristics. Under the action of the liquid surface tension, the stiffness of the oil film just makes the contact end of the oil film and the air form a crescent surface, preventing the leakage of the working medium, so as to achieve the sealing of the rotating shaft;
2, the sealing capacity of the oil seal depends on the thickness of the sealing surface oil film, the thickness is too large, the oil seal leakage; If the thickness is too small, dry friction may occur, causing oil seal and shaft wear; There is no oil film between the seal lip and the shaft, which is easy to cause heat and wear;
3, therefore, in the installation, it is necessary to apply some oil on the sealing ring, while ensuring that the skeleton oil seal is vertical with the axis line, if not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive wear of the sealing lip. During operation, the lubricant in the shell exudes a little to achieve the ideal state of forming an oil film at the sealing surface.
Crankshaft front and rear seal is to prevent oil leakage and external dust into, generally with a steel core rubber ring seal, the outer ring has a steel core through the interference fit embedded in the cylinder seal ring seat ring, fixed. The inner ring is elastic, and there is a thin spring in the sealing ring, which uses elastic pressure to wrap the crankshaft journal, separating the inside and outside space, and does not affect the rotation of the crankshaft.
The sealing principle of the O-ring is that the O-ring is flattened by the extrusion of metal objects to form a seal. The elastic space of the sealing ring is the squeezed space of the seal.

After the crankshaft oil seal oil leakage, the most direct impact is the increase of oil consumption, the reduction of oil volume, the lubrication effect of the engine will have an impact, thus increasing the wear of the engine and reducing the life of the engine.
The oil leakage of crankshaft rear oil seal can be roughly divided into three reasons: cutting edge oil leakage, peripheral oil leakage, and oil leakage caused by non-quality reasons.
Common causes of cutting edge oil leakage are: 1, oil seal edge wear or partial wear; 2, oil seal edge aging; 3, oil seal spring off; Wrong direction of oil seal; 4. The eccentricity of the shaft is serious.
The common causes of peripheral oil leakage are: 1. Oil seal deformation; 2, oil seal loose; 3, the oil seal tilt phenomenon; 4. Scratches on the outer edge of the oil seal; 5. Abnormal size of oil seal.
Oil leakage caused by non-quality reasons may be due to: 1. Foreign bodies on the lip; 2, crankcase system pressure is too large; 3, abnormal high temperature causes lip hardening.
Since there is no real car, it is impossible to make an accurate judgment.
In reality, it is recommended to go to the 4S shop or professional auto repair shop in time, and first let the maintenance personnel check to see where the problem is.
We can't fix it until we know what's wrong, okay
