The prior art has the following defects or problems:
the existing bearing usually utilizes a lubricating oil form, and has the defects of complex structure, troublesome disassembly and assembly, more supporting facilities, high power consumption and poor use effect in the installation and use processes.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's weak point, provide thrust air bearing elastic support structure, it is complicated to have solved the proposed structure in the background art, and the dismouting is troublesome, and supporting facility is many, and the consumption is high, the not good problem of result of use simultaneously.
In order to achieve the above object, the utility model provides a following technical scheme: thrust air bearing elastic support structure, including thrust bearing, thrust bearing's center department is provided with the centre bore, centre bore and thrust bearing's junction is provided with the lead angle, thrust bearing's top is provided with the recess, the upper end of recess is provided with the elastic support who is connected with thrust bearing, the inside of elastic support is provided with the through-hole.
As the utility model discloses a preferred technical scheme, the angle of lead angle is 45, and is ring shape and distributes evenly around the centre bore.
As the utility model discloses a preferred technical scheme, the quantity of through-hole is half of the quantity of elastic support, elastic support divide into take the through-hole and do not take two kinds of through-hole, and the even distribution of two kinds of elastic support is on thrust bearing's surface.
As the utility model discloses a preferred technical scheme, the quantity of recess is the same with the quantity of through-hole, and the even distribution of recess is in the bottom of through-hole.
Compared with the prior art, the utility model provides a thrust air bearing elastic support structure possesses following beneficial effect:
