Description

Technical Field

It is mainly used for the automatic assembly of turbocharger shaft seals and piston rings, and belongs to the field of turbochargers. Background Technology

[0002] The main function of the turbocharger oil seal ring is to establish a sealing barrier between the high-speed rotating shaft and the fixed housing to prevent the lubricating oil in the turbocharger intermediate body from leaking out and the high-pressure air from the outside from entering the intermediate body. In the turbocharger, the working environment of the seal ring is very harsh, and it is subjected to axial thrust, high-temperature friction, and cyclic operating temperature shock.

[0003] To ensure that the turbocharger does not leak oil under any operating conditions, in addition to ensuring the dimensional accuracy of the parts, the assembly process of the sealing ring and shaft seal is also crucial. Currently, most of the assembly is done manually using auxiliary tooling, but this is generally inefficient and cannot guarantee assembly consistency, which will affect the working performance of the turbocharger shaft seal.

[0004] Chinese patent CN211715389U, published on October 20, 2020, discloses a utility model patent entitled "A shaft seal structure for an exhaust gas turbocharger with an oil baffle plate."
