Technical field
The utility model relates to a kind of radiation fan and hydraulic bearing structure, refers to a kind of improvement design of hydrodynamic pressure bearing especially, builds the area of pressure so as to increase, makes that to build the pressure degree stronger, can reduce the number that collection presses groove to be provided with, and to reduce processing, cost is reduced.
Background technique
FDB is to utilize fluid to produce lubrication between axle and bearing, produces collision with bearing when avoiding axle to rotate and wears away.Known FDB can be divided into two kinds of hydrostatic bearing and hydraulic bearings.
The inside of hydrostatic bearing just stores lubricant oil under normal temperature, can utilize the pressure support axle of lubricant oil during rotation, if axle skew, then make axle return back to the tram in the pressurization of skew side, this kind pressuring method needs external system and matches, so hydrostatic bearing is used in large-scale machinery usually.
Hydraulic bearing is used in miniature motor (as radiation fan) usually, its principle is to utilize fine collection to press the stream force characteristic of groove, when axle is rotated, press the lubricant oil of groove to be drawn to set up dynamic pressure, axle is supported on the middle position of bearing inside thereby be positioned at collection.
It is "＜" type that the collection of known hydraulic bearing is pressed groove shape, when the axle entry into service, these collection press the lubricant oil of groove inside to press groove to move to the central position that collection is pressed groove along collection, to set up dynamic pressure, because the area of building pressure only limits to collect the central position of the pressing groove turning point of type (promptly＜), therefore the area of building pressure is less, relative build the pressure degree partly a little less than, plurality purpose collection often need be set press groove, can reach the predetermined pressure degree of building, to make that thus processing is more complicated, cost is increased.
Therefore, the improving of the above-mentioned defective of the design people's thoughts is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
