Abstract
Provided is a hybrid fluid film bearing. The hybrid fluid film bearing comprises: a bearing housing installed on an outer diameter surface of a rotary shaft in the form of being coupled via a ring; a sleeve ring installed between the rotary shaft and the bearing housing, having gaps respectively with the rotary shaft and the bearing housing, and having a side in the circumferential direction opened in the radial direction; and a fixing pin connected between the bearing housing and the sleeve ring, and supported by the bearing housing so as to restrict rotation of the sleeve ring when the rotary shaft rotates. Also, the hybrid fluid film bearing may further comprise a compliant spring damper which is provided in the gap between the bearing housing and the sleeve ring and is provided as one or more bump foils.
