摘要： Disclosed are a hydrodynamic bearing structure(10) for bearing a cooling fan(3) and a method of assembling the same. The hydrodynamic bearing structure(10) comprises a housing(20), a hydrodynamic bearing(30), a rotation shaft(40), a thrust member(50) and a bottom plate(24). The hydrodynamic bearing(30) is mounted in an accommodating space(21) within the housing(20) The rotation shaft(40) is disposed through a rotation shaft hole(31) of the hydrodynamic bearing(30). The thrust member(50) is disposed on an end portion of the rotation shaft(40) and accommodated between a bottom surface of the hydrodynamic bearing(30) and a top surface of the bottom plate(24). A plurality of guiding grooves(51) are disposed in a surface of the thrust member(50), so that an oil layer applied with pressure is formed on the surface of the thrust member(50) to maintain stable rotation of the rotation shaft(40) and reduce the deflection and vibration of the fan(3) during rotation.

摘要： The invention relates to plain thrust bearings, wherein one working surface of which is made of siliconized graphite (or other antifriction material with similar characteristics) and can be used in assemblies of electrical machines and hydraulic machines having thrust bearings of a large size (with a diameter up to 900 mm), preferably electric motors driving a main circulation pump assembly (MCPA) of reactor assemblies, for example, in nuclear power plants. The plain thrust bearing comprises interleaving bearing bands and slots on the side facing to a set of sector. The bearing disk is provided with mounting surfaces, wherein external and internal rings securing the sectors made of antifriction material through elastic elements are mounted on the mounting surfaces. The sectors are fixed to deter them from rotation relative the bearing ring by intermediate bars arranged between the sectors, wherein the bars are fixed by inserting their pins into the openings in the bearing disk. The sectors made of antifriction material are provided with steps for the external and internal rings, wherein upper parts of the sectors are provided with roundings and lower parts of the sectors are provided with slots for mutual axial fixation. A sector's lead-in edge is shaped approximately as a parabolic curve. Cooling and lubricating is carried out through interleaving channels formed by the bars, the sectors, the external and the internal rings.
