Equally, therefore each shaft needs to configure the tilting-pad bearing of a model, and buying and assembling to tilting-pad bearing are brought
Trouble.
Utility model content
The purpose of this utility model is that be directed to problems of the prior art, being related to one kind, can to change bearing diameter big
Small tilting-pad bearing, uses suitable for the shaft of different-diameter.
For the attainment of one's purpose, technical solution provided by the utility model is：
A kind of tilting-pad bearing for the compressor rotation shaft that the utility model is related to, including upper watt body, lower watt of body, Shang watt body and
Lower watt of body is bolted to connection, and forms loop configuration, it is characterised in that：It further includes the tile fragment of some crescent shapes and two
Block oil blocking ring, the front and rear surfaces of tile fragment are equipped with raised line, and the medial surface of two pieces of oil blocking rings is equipped with some grooves, the width of groove
Width than the raised line on tile fragment is big, and the oil blocking ring is separately fixed at the front and rear sides of upper and lower watt of body, oil resistance by bolt
The internal diameter of ring is less than the internal diameter of the loop configuration of upper and lower watt of body composition, the loop configuration of two pieces of oil blocking rings and upper and lower watt of body composition
Inner ring form annular notches, the tile fragment is located in annular notches at equal intervals, and the raised line of every piece of tile fragment is correspondingly arranged at resistance
In one of groove of oil ring, there are gap between adjacent tile fragment；The side wall of the upper and lower watt of body is equipped with some oil spouts
Mouth, and the lateral surface of tile fragment is withstood on the one-to-one adjustable bolt of tile fragment, the end of adjustable bolt, atomizer is located at
Gap between adjacent tile fragment.
Preferably, the end of the adjustable bolt withstands on the centre position of tile fragment.
Preferably, the front and rear surfaces of described upper watt body and lower watt of body are stepped, the thickness of the oil blocking ring and rank
The height of ladder is identical.After oil blocking ring is bolted on the circular ring structure of watt body and lower watt of body composition, the table of oil blocking ring
Face is flushed with the surface of upper and lower watt of body.
Using technical solution provided by the utility model, compared with prior art, have the advantages that：
The tilting-pad bearing for the compressor rotation shaft that the utility model is related to can be adjusted according to the diameter of compressor rotation shaft
The size of bearing bore diameter, when choosing bearing, it is only necessary to the tilting-pad bearing of same model is bought, according to the diameter of shaft during assembling
Size is adjusted, simple in structure, easy to assembly.
