Description
Technical field
Move fat certainly the present invention relates to a kind of for the bearing that bearing injects lubricating grease fat and extracts the aging grease in bearing out
System, move the bearing waste grease auto-collection system of fat system certainly the invention further relates to the bearing.
Background technology
The lubrication of bearing mainly has two ways, a kind of liquid oil lubrication, and this class bearing must be provided in casing,
Fluid is contained with casing, the effect of this kind of lubrication is good, and cleannes are high, but are not particularly suited for all bearings, because some axles
Enclosure interior can not be arranged on by holding, and opened and just belonged to this class bearing for the bearing in wind power plant, building machinery etc., this kind of
Bearing just needs to be lubricated using grease, and the viscosity of grease is larger, is not easy to flow out, and the lubrication between bearing internal external circle is empty
Between be completely enclosed in the case of, lubricating grease also will not flow out, still, as time goes by, lubricating grease can aging, be hardened,
This just needs to inject new grease into lubricating place and replaces old grease, in the prior art can be by fueller to bearing
Grease is provided, fueller has oil feed pump, and oil feed pump is generally plunger pump or gear pump, the distribution of oil feed pump contiguous block formula
Device, distributor connect with each oil inlet on each bearing respectively.With the injection of fresh oil fat, the old grease after aging
It can be extruded, oil-out is further opened with bearing arrangement, old grease will come out in oil-out, for the old oil for preventing from out
Fat pollutes environment, grease collection bottle can be set on oil-out, first, it is regularly to empty these and be sometimes difficult to close bottle very much
It is troublesome.In addition such danger be present, i.e., if bottle does not empty in time, lubricant is just uncontrollably arranged from bearing
Flowed out in structure.Further, since the viscosity of old grease is big, hardness is high, it is necessary to which very big strength could be extruded, just
The compression resistance for being higher than bearing enclosure in the pressure for many times, extruding old grease is caused, causes grease to be flowed by oil enveloping structure
Go out, the small new grease of the even viscosity flowed out, cause not to be collected into grease in grease collection bottle, grease is all by bearing
Flowed out in structure, pollution environment is not said, can also be caused bearing lubrication bad, in order to solve this problem, come out suction
Device, old grease is pumped out using aspirator, it is in the prior art, flat between aspiration and injection rate in order to balance
Weighing apparatus, using the interlocking between injection and suction, it is, the power of injection device and aspirator is one, while start simultaneously
Stop simultaneously, with this balance between ensureing to aspirate and injecting, still, this simple relation is difficult balance suction and injection
Between relation, in order to ensure there is certain lubricating grease bearing arrangement inside because, if Bearing inner is without lubricating grease meeting
Cause huge loss, the aspiration of aspirator typically all set it is somewhat small, along with the viscosity of old grease is larger, meeting
The problem of in the presence of certain evacuation amount, this is resulted in, and suction is inadequate, and old grease overstocks, so, inside bearing arrangement
Pressure can be excessive, will destroy bearing arrangement with the passage of time.Meanwhile just know that the pressure inside bearing arrangement is excessive at last,
Old grease can not be aspirated.
The content of the invention
It is an object of the invention to provide a kind of bearing arrangement, and to solve, injection device and aspirator are mutual in the prior art
