Oil Seal Introduction:
The oil seal is a mechanical component used to seal oil (oil is the most common liquid substance in the transmission system). It isolates the parts of the transmission parts that need to be lubricated from the output parts, so as not to let the lubricating oil leak and external dust, muddy water and other impurities. enter. An oil seal is required for all parts of the operating body box that have liquid lubricant and are connected to the outside. The shaft seal of the first internal combustion engine was a simple packing that was replaced by a leather lip seal in the 1920s. In the 1930s, after the synthetic rubber compatible with mineral lubricating oil was promoted, a variety of lip seals with various appearances and appearances appeared constantly. At present, it can be roughly divided into: felt oil seal, rubber oil seal, composite material oil seal, labyrinth oil seal, spiral oil seal, mechanical oil seal, etc., and a variety of split oil seals are conveniently installed. The felt oil seal is an oil seal used earlier. Due to its poor sealing effect, the wear is fast and the service life is short, and it has not been used in a large amount. At present, a large number of applications are rubber bone oil seals, which have better sealing performance, but due to the limitations of their materials, the sealing life is short and the replacement is frequent, so that the cost of replacing the oil seals far exceeds the price of the oil seal itself.
1. The installation of the oil seal can be flush with the front end of the casing aperture, or it can be close to the low section of the casing aperture.
2. The reference planes for installation and positioning should be machined surfaces, and the unprocessed reference planes cannot be used.
3. The outer diameter of the oil seal should be coated with a layer of lubricant.
4, using hydraulic or pneumatic uniform pressure compression oil seal.
The matching surface of the oil package is flush with the reference surface of the housing to ensure the verticality of the shaft and the center of the shaft after the shaft is installed, so that the oil seal lip becomes a line contact belt on the shaft surface to achieve a good sealing effect.
wrong assembly methods and improvement measures
a. The hammer directly strikes the oil seal.
b. No oil seal is forcibly assembled on the reference surface.
c. Oil seal tooling is unreasonable.
a. The oil seal is deformed.
b, outer diameter of oil seal and dust lip, scratch
c. Oil seal and skeleton degumming.
d. The oil seal spring comes off.
e. The main lip of the oil seal is deformed.
