摘要： A piezoelectric ultrasonic suspension in gas for creating a contactless bearing support of a precision instrument and specifically an electromagnetic motor. A gas micro-film of elevated pressure is formed between the adjoining surfaces of a spherical saddle and a spherical trunnion. The spherical trunnion is spaced apart from the spherical surface of a saddle by a gas micro-film when the piezoresonator is excited.
