According to an exemplary embodiment, rotor, bearing or the part both them is applied self-lubricating coat in use, this self-lubricating coat in use is formed to be preserved lubricant when machine operates with normal temps and discharges this lubricant when machine temperature increases to above certain threshold temperature.
An exemplary embodiment according to Fig. 1, compressor 10 comprises and being configured to relative to rotor 14 rotating rotor 12 etc.Rotor 12 is such as supported by one or more bearing 16 at two ends.Various bearing is as known in the art, and any bearing in these bearings can be used for support rotor 12.An example of bearing is shaft bearing, and it is described in U.S. Patent No. 6,361, and in 215, the whole content of this patent is incorporated herein by reference.
Shaft bearing 16 uses the one or more liners (pad) 18 of support rotor 12, and oil injects between liner 18 and rotor 12 at interface 20 place to reduce to rub and/or cool this interface.Pump (not shown) can be used for pump oil through the passage 22 in each liner to interface 20 place liner 18 and rotor 12.If oil fails to be sent to interface 20, then the temperature of this interface will increase to above acceptable value, this may damage bearing 16, rotor 12 or they both.
An exemplary embodiment according to Fig. 2, rotor 12 or bearing 16 any one or the part both them can applied self-lubricating layers 24.Self-lubricating layer 24 can be deposited on substrate 26 as shown in Figure 2, and substrate 26 can be one of rotor 12 and/or bearing 16.When self-lubricating layer 24 is deposited on rotor 12, expect that this layer is deposited as directly towards bearing 16.
Layer 24 can comprise the base material 28 be deposited on substrate 24.Base material can comprise the metal for bearing, such as graphitic cast iron, stainless steel, carbon steel, nonferrous alloy etc.In one application, base material is plasticity, such as, comprise the material with low carbon content and high Fe, Ni or cobalt contents.In Another Application, base material does not comprise Cr.In another application, base material can comprise non-ferrous metal, makes base material be plasticity.Base material deposits by method as known in the art.Such as, base material can be sprayed on substrate.But in one application, substrate material layer 28 is not a part for layer 24.Deposition substrate material layer 28 is to guarantee the better adhesion between self-lubricating layer 24 and substrate 26.
The porous layer 30 of self-lubricating function is provided to be formed in substrate material layer 28 or to be directly formed on substrate 26.Porous layer 30 can comprise metal and promote the compound that hole is formed in porous layer 30.Metal can be for one or more in the metal of bearing, such as graphitic cast iron, stainless steel, carbon steel etc., this layer hardness, bearing load of depending on application, expecting.Compound can be powdered graphite, molybdenumdisulphide (MoS 2), tungsten sulfide (WS 2) in one or more.Metal as liquid spray in substrate material layer 28.Such as, electric arc or plasma spraying can be used for spraying liquid metal and compound.The rare gas element be under pressure not only can be used for transmitting molten metal from rifle or for other device of coated substrates, but also can be used for compound to embed in molten metal.Such as, rare gas element can be nitrogen (N).
Porous layer 30 is shown in Figure 3 for the multiple holes 32 having and run through metal and compound 34 distribution.The quantity of multiple hole 32 depends on many variablees.Such as, the quantity of hole can be depending on liquid metal and sprays to temperature on substrate, the pressure of rare gas element, distance, concrete metal used, particular compound used etc. between the rifle of spraying liquid metal and substrate.In one application, the thickness of self-lubricating layer 30 is between several microns and several millimeters.
Once porous layer 30 is formed on substrate 26 and the temperature of assembly is reduced to room temperature (such as, 25 DEG C), then the closing of pores, such as, if porous layer 30 is immersed in liquid bath, then seldom this liquid of amount enters the hole of layer 30.But if layer 30 exposes (such as, submergence) in the oil bath being in high temperature together with substrate 26, then the hole 32 of layer 30 is opened and oil starts to fill hole.High temperature range can from 80 DEG C to 500 DEG C, and this depends on the type (synthesis or nonsynthetic etc.) of such as oil.Use oil as an example, but any lubricant all can be used for the part or all of of the hole of partly packing layer 30.
Then substrate 26 and layer 30 are cooled to room temperature to seal hole, and absorbed lubricant is housed in hole 32.Then the one or more middle use in machine as discussed above has this substrate of self-lubricating layer 30.Therefore, when this machine cannot the interface between rotor and bearing oil is provided time, the temperature of interface increases to above the temperature that the hole of self-lubricating layer 30 is opened, and which dictates that porous layer 30 starts the interface release lubricant between rotor and bearing.
This self-lubricating layer 30, depends on its size and in bearing and/or epitrochanterian distribution, can provide the safety operation of several minutes (if not a few hours) to the operator of machine, although the major oil supply mechanism failure of this machine.Like this, operator has makes whole processing line shut down the necessary time in a controlled manner, and does not damage the safety of other machine forming this processing line.
Although thick self-lubricating layer 30 can be provided on conscious, to provide the longer supply of lubricant, find that thick-layer is easy to cracking and therefore has the shorter life-span.In addition, the cracking in thick-layer allows lubricant than the more Zao effusion of expection and also can endanger the adhesion of porous layer to substrate.On the contrary, thin layer is owing to may preserve not enough lubricant but less desirable.Therefore, the appropriate thickness of self-lubricating layer 30 depends on the quantity etc. of the type of machine, the weight of rotor, the quantity of liner and bearing.
Exemplary embodiment according to Fig. 4, exists a kind of for providing the method for self-lubricating coat in use on substrate.The method comprises: step 400, utilizes gas on substrate, spray at least one deck liquid metal; Step 402, is added into liquid metal by compound when substrate sprays; Step 404, the substrate comprising metal and compound forms porous layer, and wherein porous layer has multiple hole; Step 406, heated porous layer is to open hole; Step 408, fills hole with lubricating substance, makes a part for lubricating substance be housed in one or more hole; And step 410, lubricating substance is trapped in hole with closed hole by cooling porous layer.
It should be pointed out that the gas for depositing liquid metal can be rare gas element.But, in order to deposit non-iron layer, can N be used 2gas, because N 2more cheap.And, N 2gas can provide more plasticity to porous layer, and this is desired.N 2gas is better than argon gas or pressurized air, because this gas avoids the oxidation of liquid metal interalloy element, and does not also change the composition of settled layer.
