Oil Seal Manufacturing Process Is Not Complicated

Oct 10, 2017

Oil seals are used to seal grease (oil is the most common liquid substance in the transmission system, but also refers to the general liquid substance meaning) of the mechanical components, it will be the transmission components in need of lubrication components and output parts isolation, Oil Seals not to let the lubricant leakage.

Sealing principle of oil seals involves two factors: first, dynamic seal, is the contact between the seal lip and the rotating shaft surface, is the most important function of oil seal, Oil Seals the second is the sealing of the cavity, mainly the location of the outer edge of the oil seal in the cavity.

The oil seal has the advantages of simple structure, light weight, small installation position and easy processing.

Oil seal, that is, the sealing of lubricating oil. Oil seals are often used in various mechanical bearings, especially outside of rolling bearings. The function of oil seal is to isolate the oil chamber and equipment, to prevent the oil ester from leaking and the outside dust into the equipment. The oil seal differs from other lip seals in that it has a more resilient lip, Oil Seals with a narrow contact width (about 0.5mm) and the distribution of the contact stress is in sharp shape.

Characteristics of oil Seals

1, oil seal structure simple, easy to manufacture. Simple oil seal can be molded once, even the most complex oil seals, manufacturing process is not complicated. Metal skeleton oil seals also only through stamping, bonding, inlay, Oil Seals molding and other processes can be metal and rubber composition of the required oil seal.

2, oil seal weight light, less supplies. Each type of oil seal is a combination of thin-walled metal and rubber parts, and its material consumption is very low, so the weight of each oil seal is very light.

3, the installation position of oil seal is small, the axial size is small, easy to process, and make the machine compact.

4, the seal of oil seal function is good, Oil Seals the service life is long. It has a certain adaptability to the vibration of the machine and the eccentricity of the spindle.

5, easy to remove oil seals, inspection and profits.

6. The price of oil seal is cheap.
