Hydrodynamic thrust bearing
WebA hydrodynamic bearing is typically a low-clearance assembly that relies on a film of oil (and occasionally air) that develops space while the spindle is rotating. The bearings transmit (float) the load on self-renewing film of lubricant. The most basic hydrodynamic bearing is the journal bearing. What is hydrodynamic support? WebThe Hydrodynamic thrust bearing transmits the rotating shaft’s axial thrust load to the frame of the motor, which is mechanically supported in the well. The axial thrust load is transmitted through the bearing on a self-renewing film of …
