Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of centrifugal compressor thrust bearings.
Background technology
The industries such as petrochemical industry, refrigeration generally convey, compress various gases with centrifugal compressor both at home and abroad at present, and bearing system
System is the essential important spare part of centrifugal compressor, directly determines operation and the stability of centrifugal compressor, is centrifugation pressure
The main guarantee of contracting function normal operation and service life.The thrust bearing of such equipment is generally using fixed at present
The mode of thrust face or the more complicated tilting-pad bearing of structure realizes that there are certain offices for the bearing load of fixed thrust face
Limit, and without any adaptive ability, it is stable poor, and then system is complex for above-mentioned tilting-pad bearing, structure design and
Lubricating oil system is cumbersome, and appearance and size is compared to larger, and installing and dismounting is inconvenient, and manufacturing cost is high.
Invention content
The prior art is defective for above-mentioned thrust bearing by the present invention, provides a kind of centrifugal compressor thrust bearing, should
Bearing includes thrust block, clip, elastic mattress, adjust pad, bear box, positioning pin, and adjust pad is connect with bear box, bullet
Power pad is connect with adjust pad, thrust block respectively, and positioning pin, clip difference are also associated between adjust pad and bear box
It is connect with bear box, thrust block.
Further, the thrust face of thrust block has poured babbit layer.
Further, the thickness of babbit layer is 1mm~2mm, and more specifically, babbit layer is thickness
1.5mm。
Further, babbit is kamash alloy.
Further, thrust block is 6, and is designed with raised line in thrust block bottom.
Further, the boss that have 6 bumps with the mounting surface of elastic mattress in adjust pad alternate.
Further, elastic mattress is the stainless steel of 1.5mm~2.5mm thickness, and more specifically, the thickness of elastic mattress is 2mm.
Further, the raised line of each thrust block bottom is located between two boss of adjust pad.
The present invention as a result of the technical characteristics such as independent thrust block and elastic mattress, adjust pad, positioning pin,
Raised line is designed on thrust block, pours babbit layer on thrust block, and the upper concave-convex alternate boss of design, makes in adjust pad
The thrust bearing adaptive adjustment capability for obtaining this programme significantly increases, and operation more stablizes, is reliable, and this programme is simple in structure tight
Gather, the precision between bearing is easy to ensure, installing and dismounting is more convenient, is readily produced manufacture and maintaining, be effectively ensured from
The stability and reliability of heart Compressor Group operation, to effectively increase production efficiency.

Specific implementation mode
It elaborates to technical scheme of the present invention below with reference to attached drawing, so that those skilled in the art are best understood from
This programme.
As shown in attached drawing 1, attached drawing 2, which includes thrust block 1, clip 2, elastic mattress 3, adjustment
Gasket 4, bear box 5, positioning pin 6, adjust pad 4 are connect with bear box 5, elastic mattress 3 respectively with adjust pad 4, thrust
Block 1 connects, and is also associated with positioning pin 6 between adjust pad 4 and bear box 5, and positioning pin has and prevents adjust pad 4 and axis
The function of being rotated between shell 5 is held, clip 2 is connect with bear box 5, thrust block 1 respectively；More specifically, the thrust of thrust block 1
Face has poured babbit layer, and thickness is 1mm~2mm, and the thickness 1.5mm of babbit layer, babbit is tinbase conjunction
Gold further decreases the friction coefficient of bearing, improves bearing wear resistance；Thrust block 1 is 6, as shown in attached drawing 5, attached drawing 6,
1 bottom of thrust block is designed with raised line 7, as shown in attached drawing 3, attached drawing 4, has 6 with the mounting surface of elastic mattress 3 in adjust pad 4
Concave-convex alternate boss 8, elastic mattress 3 are the stainless steel of 1.5mm~2.5mm thickness；More specifically, 3 thickness of elastic mattress is 2mm；
The raised line 7 of each 1 bottom of thrust block is located between two boss 8 of adjust pad 4, which has stronger adaptive
Regulating power, bearing installing and dismounting is more convenient, is readily produced manufacture and maintaining.It is outer on bear box 5 when concrete application
Circle and end face have installation positioning function, which is installed on using radial plus end face scheme inside centrifugal compressor
Bearing block.The present invention can effectively improve the adaptive ability and operation stability and reliability of thrust bearing, the bearing arrangement
Simple and compact is easily installed and safeguards.
