TG4 Skeleton Oil Seal Mechanical Seal

Skeleton oil seal structure of three parts: the oil seal body, strengthen the skeleton and the spiral spring. Seal according to the different parts of the body is divided into the bottom, waist, blade and sealing lip, etc. Usually, in the free state of skeleton oil seal, the inner diameter smaller than outer diameter, which has a certain amount of interference.Therefore, after the oil seal in oil seal and shaft, oil seal edge pressure and self-tightening helical spring contraction force on the shaft of the radial force, after a period of time after the operation, the pressure will be reduced and even disappear quickly, thus, combined with spring can compensates for oil seal force at any time.Skeleton oil seal is needed in the role of the general is to driving part, lubrication components and output component segregation, unapt let lubricating oil leakage, is typically used for rotation axis of rotation is a lip seal.
