Related introduction of skeleton oil seal
Skeleton oil seal is a typical representative of oil seal, general said oil seal is refers to the skeleton oil seal. Generally is the role of oil seal driving part need lubrication components and output components in isolation, not let lubricating oil leakage. Skeleton is like the inside of the concrete members reinforced, have the effect of strengthening, and makes the oil seal can keep shape and tension. According to the structural form can be divided into single lip skeleton oil seal and double lip skeleton oil seal. Lips skeleton oil seal deputy lip dust-proof effect, to prevent external dust, impurities and so on into the machine inside. According to the skeleton skeleton oil seal type can be divided into the package, exposed skeleton oil seal and prefabricated oil seal. According to the working conditions can be divided into rotation skeleton oil seal and return type skeleton oil seal. Used for gasoline engine crankshaft, diesel engine crankshaft, transmission, differential, shock absorber, engine, axle parts, etc.

The sealing principle of skeleton oil seal
Due to the exist between oil seal and the shaft seal edge control of oil film, the oil film with fluid lubrication properties. Under the effect of the surface tension of liquid, oil film stiffness just makes the oil film is exposed to air end to form a new moon face, prevent the leakage of working medium, so as to realize the sealing of the axis of rotation. Oil seal sealing ability, depend on the sealing surface of the oil film thickness, the thickness is too big, oil seal leakage; Thickness is too small, dry friction may occur and cause oil seal and shaft wear; No oil film between the sealing lip on the shaft, easy cause fever, wear and tear.
