Description
Technical field
The utility model relates to technical field of bearings, in particular to a kind of graphite oil-free lubricates bearing.
Background technique
Bearing is common a kind of sliding parts in mechanical industry, have again in material metal, nonmetallic, composite material it
Not.Graphite bearing is then the performance requirement with mechanical equipment, the carbonaceous developed and grown up on the basis of metal bearing
Bearing, with graphite material for main substrate.Graphite bearing has the characteristic different from metal bearing, is mainly manifested in: self-lubricating, resistance to
High temperature, corrosion-resistant, light etc..
Bearing is divided into rolling bearing and sliding bearing, and graphite bearing is chiefly used in sliding bearing.Applied to food, beverage,
In terms of the bearings such as transporter, drying machine, weaving loom, motor for submerged pump in the industrial departments such as weaving, chemical industry, these positions are as used
Grease lubricant inevitably causes to pollute, and the self-lubrication of graphite bearing is very strong, corrosion-resistant, can without using lubricating oil and
It is operated for a long time.
Existing graphite bearing is typically all that graphite annulus is equipped between bearing inner race and bearing outer ring, passes through rotation, stone
Mo Huanhui generates graphite bits, carries out self-lubricating by graphite bits, and since the graphite bits size of generation is indefinite, graphite was considered to be worth doing sometimes
It will lead to bearing greatly to block, and then influence bearing and use, therefore the utility model devises a kind of graphite oil-free lubrication bearing,
Utility model content
In view of the above-mentioned problems, effectively preventing the purpose of this utility model is that propose a kind of graphite oil-free lubrication bearing
It gets stuck, self-lubricating effect is good, and improves the intensity of graphite bearing.
The utility model solves technical solution used by above-mentioned technical problem: a kind of graphite oil-free lubrication bearing,
It is characterized in that, comprising: outer ring, inner ring, screen membrane, graphite powder box, circumferentially arranged with multiple balls between the inner ring and outer ring,
Graphite powder is filled between the ball, the periphery uniform intervals of the outer ring are provided with dovetail groove and dovetail, the graphite
Powder box is equipped with the dovetail groove and dovetail being cooperatively connected with outer ring, and the graphite powder box and outer ring pass through dovetail groove and dovetail
It is cooperatively connected, the dovetail of the outer ring is equipped with diversion pipe, and the diversion pipe is connected to the graphite powder box and the outer ring, institute
It states and posts screen membrane on the inside of outer ring, the graphite powder box is provided with graphite powder.
Further, the inner ring is using ceramic inner ring.
Further, the outer ring is using ceramic outer ring.
Further, it is flushed on the inside of one end of the diversion pipe and the outer ring, the other end stretches out the outside of the outer ring.
Utility model has the advantages that the utility model is provided with graphite powder box, and graphite powder in the outside of outer ring
By dovetail groove and dovetail feather joint between box and outer ring, firm and reliable connection passes through diversion pipe between graphite powder box and outer ring
It is connected to, the graphite powder in graphite powder box is constantly flowed between outer ring and inner ring by diversion pipe, plays the role of lubrication, effectively
Prevent in the prior art due to graphite bits it is excessive caused by get stuck, can and in one layer of screen membrane of outer ring inner adhesion
The graphite powder for further filtering out larger particles further prevents getting stuck；And the inner ring and outer ring of the utility model is all using pottery
Porcelain inner ring and ceramic outer ring, can anticorrosion can enhance the intensity of bearing again because graphite bearing in the prior art is all adopted
With graphite circle, intensity is not high.
