The problems such as loading capability and weak intensity, wherein guide bearing lubricate at work can effectively improve the operating efficiency of bearing；In high temperature
Under environment, rotating shaft locking phenomenon occurs in guide bearing.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of stove water pump guide bearing.
In order to solve the above technical problems, the technical scheme is that：
A kind of stove water pump guide bearing, including guide shaft bearing, guide bearing body, the first tank, the second tank, the guide bearing sheet
Body is vertical in the guide shaft bearing, and the guide bearing body circumference side offers first tank and second water
Groove；Guide bearing body described in the first tank insertion, second bottom of gullet has spacing with the guide shaft bearing；
The guide bearing body includes metal level and polymeric layer, and the metal level is located at polymeric layer periphery.
Preferably, first tank and the spaced setting of second tank.
Preferably, the polymeric layer includes 70~80 parts by weight polyether-ether-ketones；The polybenzoate of 20~30 parts by weight；15~
25 parts by weight solids lubricants；Processing aid.
Preferably, the kollag at least includes one kind in graphite, molybdenum disulfide, polytetrafluoroethylene (PTFE).
Preferably, the processing aid at least includes 2~3 parts by weight silicone oil or white oil, 0.4~0.5 parts by weight antioxidant.
Preferably, there is 0.3mm ~ 0.5mm gap in the metal level and the polymeric layer.
Beneficial effects of the present invention are：（1）First tank and the negotiable water of the second tank or other lubricants, to guide shaft
Hold and serve lubrication；（2）The bearing has good wearability, thermal conductivity and bearing capacity；（3）Metal level and polymer
There is gap between layer, it is to avoid the rotating shaft locking phenomenon that thermal expansion is brought.
Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention.
Embodiment
To make to have a better understanding and awareness to architectural feature of the invention and the effect reached, to preferably
Embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in Figure 1, a kind of stove water pump guide bearing, including guide shaft bearing 100, guide bearing body 200, the first tank 400,
Second tank 300, the guide bearing body 200 is vertical in the guide shaft bearing 100, the circumference of guide bearing body 200
Side offers first tank 400 and second tank 300；Guide bearing body described in the insertion of first tank 400
200, there is spacing the bottom of the second tank 300 with the guide shaft bearing 100；First tank 400 and second tank
300 spaced settings.Wherein, first tank 400 and the negotiable water of second tank 300 or other lubricants,
The lubricant effect of guide bearing is added to a certain extent, improves the operating efficiency of guide bearing.

During work, heat can be produced, in high temperature environments, the meeting of polymeric layer 201 expanded by heating, herein, the metal level 202
Gap between the polymeric layer 201 is exactly to provide certain space to the polymeric layer 201 expansion, so as to avoid
Under hot environment, the polymeric layer 201 expands the rotating shaft locking phenomenon brought to guide bearing.The metal level 202 is specific
It is that, using high-quality low-carbon steel back as matrix, surface sintering Redford alloy alloy, the guide bearing has good wearability, thermal conductivity
And bearing capacity.
The polymeric layer 201 includes 70~80 parts by weight polyether-ether-ketones；The polybenzoate of 20~30 parts by weight；15~25 weights
Measure part kollag；Processing aid；The kollag at least includes one in graphite, molybdenum disulfide, polytetrafluoroethylene (PTFE)
Kind.The processing aid at least includes 2~3 parts by weight silicone oil or white oil, 0.4~0.5 parts by weight antioxidant.The formula is re-added
Partial lubrication body, adds the lubricating function of guide bearing itself.
Beneficial effects of the present invention are：（1）First tank and the negotiable water of the second tank or other lubricants, to guide shaft
Hold and serve lubrication；（2）The bearing has good wearability, thermal conductivity and bearing capacity；（3）Metal level and polymer
There is gap between layer, it is to avoid the rotating shaft locking phenomenon that thermal expansion is brought.
It should be understood by those skilled in the art that, the present invention is not limited to the above embodiments, above-described embodiment and explanation
