A static vacuum shafting device for an integrated rotary transformer includes: a driving component, a vacuum sealing cover, a position detection component, a shafting base, a vacuum insulation sleeve, three O-shaped seal rings, a first rolling bearing, a second rolling bearing, a bearing gap ring, a transmission shaft, a shafting flange, a walking rolling bearing, and two bearing glands. The driving component includes a motor stator, a rotary transformer stator, a motor and rotary transformer integrated rotor, a rotor flange plate and a stator-fixing pressing block which are coaxially assembled. The vacuum sealing cover includes a sealing cover upper flange, a sealing cover, and a sealing cover lower flange. The shafting device couples a motor shaft to a load rigidly, thereby achieving a “zero-transmission” method and a “zero-leakage” sealed transmission of a shafting, and is particularly suitable for a power transmission of a vacuum robot in a high-vacuum environment.
