introduction：The labyrinth seal is between the shaft and the housing，A concave-convex ring seal tooth assembly with a plurality of sequentially arranged small clearance，A series of throttling gaps and expansion cavities are formed between the sealing teeth and the shaft，Splash of lubricant through each seal tooth，There will be great resistance，Resulting in throttling effect，The speed of the lubricant is constantly reduced，The weakened lubricant flows down the inside of the seal teeth to the lower part of the annular cavity，then，The bearing is returned through an oil return hole to the lower part of the annular cavity[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is the part that fixes and reduces the friction coefficient of load in the process of mechanical transmission

introduction：There are many defects in the forging，There are many reasons for this，Caused by poor forging process，There are raw materials，Mold design is unreasonable and so on。Especially precision forgings with little or no cutting，Even more difficult to control completely。 1.Large grain Large grain size is usually due to high initial forging temperature and insufficient deformation degree、Or final forging temperature is too high、Or the degree of deformation falls into the critical deformation zone caused。The deformation of aluminum alloy is too large，texturing；The deformation temperature of superalloy is too low，Coarse grains may also be induced when the mixed deformation structure is formed，Large grain will reduce the plasticity and toughness of forging，Fatigue performance
