Description
Technical field
The utility model relates to insulation bearing technical field, is specifically related to a kind of insulation tilting bush babbit glide bearing.
Background technique
Oil whip problem when tilting bush babbit glide bearing operates for the rotor high-speed solving sliding supported condition, along with the fast development of high-speed electric expreess locomotive, has also used tilting bush babbit glide bearing in increasing high-speed electric expreess locomotive.But in motor bearings, a problem that can not avoid is exactly the corrosion needing to prevent shaft current to Babbitt.In the prior art, conventional insulation system bearing, bearing support or bearing support twine without insulating material such as latitude bands, and then compacting is without latitude band, then installs bearing.There is following problem in this insulation system bearing: 1) twines softer without latitude band and easily damage, if bearing dismantling easily damages inefficacy several times; 2) be in for a long time in severe bad border without latitude band, be easier to lose insulating properties; 3) be wound around without latitude band, the installation precision of bearing is not very high, and operation easier is large.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of insulation tilting bush babbit glide bearing.
To achieve these goals, a kind of insulation tilting bush babbit glide bearing, comprising: bearing support, Babbitt tilting bush, bearing cap, pin, pedestal;
Described bearing support is arranged in rotating shaft by Babbitt tilting bush;
Described bearing support is arranged in pedestal and the two ends of described bearing support are provided with bearing cap, and is fixedly mounted by pin,
On described bearing support, the attachment face of itself and described pedestal connecting part is provided with the Teflon layer by electrostatic spraying.
Preferably, the thickness of described Teflon layer is 0.2mm-0.5mm.
Preferably, the internal surface of described Teflon layer is also coated with glue layer, between glue layer internal surface and the outer surface of bearing support, is provided with polyamide-imide resin layer.
The beneficial effects of the utility model:
1) bearing support electrostatic spraying Teflon layer, makes Teflon layer difficult drop-off and reliability is high, good insulating.2), after bearing support spraying Teflon, can be processed by lathe, effectively improve the installation precision of bearing support.3) this edge tilting bush babbit glide bearing is used, can easy disassembly, and durable in use.

Embodiment
The purpose of this utility model is to provide a kind of insulation tilting bush babbit glide bearing, and its structure is simple, effective reinforced insulation effect.
In order to make those skilled in the art person understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figure 1 to shown in Fig. 2, the structural representation of the insulation tilting bush babbit glide bearing that Fig. 1 provides for a kind of specific embodiment of the utility model, Fig. 2 is sectional view of the present utility model.
In a kind of specific embodiment, as described in Fig. 1 to Fig. 2, the utility model provides a kind of insulation tilting bush babbit glide bearing, comprising: bearing support 1, Babbitt tilting bush 2, bearing cap 3, pin 4, pedestal 5; Described bearing support 1 is arranged in rotating shaft by Babbitt tilting bush 2; Described bearing support 1 is arranged in pedestal 5 and the two ends of described bearing support 1 are provided with bearing cap 3, and is fixedly mounted by pin 4, and on described bearing support 1, the attachment face of itself and described pedestal 5 connecting part is provided with the Teflon layer 11 by electrostatic spraying.
Concrete, Babbitt tilting bush 2 by pin 4 and bearing cap 3 spacing, and be together arranged on and be coated with on the bearing support 1 of Teflon layer; Babbitt tilting bush 2 can in bearing support 1 inner circumferential and axial runout; Whole bearing to be arranged on pedestal 5, and it has insulating properties, can prevent the shaft current in high-speed electric expreess locomotive from bearing through and damage is caused to Babbitt tilting bush 1.
Be coated with the bearing support 1 of Teflon layer 11, be made by electrostatic adsorption after heating bearing support 1, it is easy to processing and intensity is comparatively large, has reliable insulating properties to make whole bearing have higher installation precision.
Further, the thickness of described Teflon layer 11 is 0.2mm-0.5mm.
As shown in Figure 3, further, the internal surface of described Teflon layer 11 is also coated with glue layer 12, between the outer surface of glue layer 12 internal surface and bearing support 1, is provided with polyamide-imide resin layer 13.
Preferably, add the carbon particle of 11 ~ 41% in described polyamide-imide resin layer 13, the Mean particle diameter of described carbon particle is 16 ~ 46% of the thickness of described polyamide-imide resin layer 13.Such bearing support 1 surface that can make has insulating properties, and have good electrocorrosion-resisting, the carbon particle adding 11 ~ 41% can make micro-electric discharge occurs between axle and carbon particle, whole resin layer surface is scattered in by electric discharge phenomena, can put a little from carbon particle before the carried charge of resin layer increases, prevent resin layer from occurring the high temperature of local, because carbon particle is high-melting-point substances, even if therefore temperature raises along with electric discharge, also can not sustain damage, on the other hand, carbon particle is the excellent native graphite of good sliding or artificial graphite, therefore the sliding capability of bearing can be strengthened.
Preferably, be evenly distributed with glass fiber in described polyamide-imide resin layer 13, to reduce the phenomenon that bearing insulation is easily collided with, increase Elastic Contact face, contact force time buffering is installed between bearing support 1 and pedestal 5, decreases the trouble in installation process.
Preferably, described glue layer 12 is mixed by epoxy resin and epoxy curing agent.
Preferably, described epoxy resin is 6101 type epoxy resin, and epoxy curing agent is 593 type curing agent.
These are only better embodiment of the present utility model, the utility model is not limited to above-mentioned mode of execution, the structural modification that local is small may be there is in implementation process, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, and belonging within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
