Description
Technical field
The present invention relates to a kind of bearing lubrication structure, particularly relate to a kind of bearing lubrication structure that is used for slag stock pump or other rotating equipments.
Background technique
As rotating equipment, the bearing of slag stock pump has important role for the reliable operation of whole pump, therefore, will adopt rational lubricating system for the bearing lubrication under the different operating modes.In existing slag stock pump, the existing grease lubrication mode of its conventional bearing unit also has the oil lubrication mode.In the grease lubricating bearing component design, lubricated fully for lubricating grease can be carried out bearing, at shaft shoulder place, the two ends of pump shaft, two butter back-up rings are housed respectively.Each butter back-up ring cooperates the space of relative closures of formation such as end cap, bearing setting sleeve, i.e. bearing chamber.The butter back-up ring is limited in oiling agent in the less space, thereby it is lubricated fully to make that bearing obtains.This grease lubrication mode is suitable for the operating mode of low speed, underloading.Operating mode for high speed, heavy duty need adopt the mode of oil lubrication.Original oil-lubricated bearing component design, its complex structural designs relates to part and dimensional changes is more, and the operating cost height, and maintenance difficulties is big.
Summary of the invention
At the deficiencies in the prior art, the invention provides and a kind ofly need not make bigger design change and can make that existing slag stock pump is applied at a high speed, the occasion of heavy duty, realize the light exchange of two kinds of lubricating systems.
The present invention is achieved by the following technical solution: a kind of disc, this disc can be sleeved on the axle, and its card is in the form of annular discs.On the disc face of disc, evenly be provided with the oilhole that stirs that at least one runs through card thickness.Disc of the present invention can be applied to adopt the occasion of grease lubrication or oil lubrication, and when being applied to the occasion of grease lubrication, this disc plays the effect of butter back-up ring, is about to lubricating grease and is limited in the space of a relative closure, guarantees the lubricated of bearing.When being applied to the occasion of oil lubrication, this disc can drive lubricant oil and rotate with the axis, and lubricant oil is got rid of to bearing under action of centrifugal force, guarantees the lubricated of bearing.
In order to reach lubrication effect preferably, the axis that stirs oilhole among the present invention has an inclination angle with respect to the axis of disc, stir oilhole near the opening end of disc axis all in the same end face of disc, stir oilhole away from the opening end of disc axis all in another end face of disc.Adopt this kind measure, can make lubricant oil under action of centrifugal force, can produce the effect of better splashing, both helped the lubricated of bearing, help the heat radiation of lubricant oil again.
These that evenly arrange on the disc card stir the center of oilhole, it is preferably on the same center circle in arbitrary plane perpendicular to the disc axis of card, and like this, not only bearing can obtain lubricated preferably, and can make parts processing simple, save cost.
The fit of fit of the present invention butter back-up ring when adopting grease lubrication is the same, promptly respectively establishes a disc at the two ends of pump shaft.When adopting oil lubrication, disc floodlubrication oil certain depth, lubricant oil enter and stir oilhole and store up in the hole and stay.The disc band to store up to stay and is stirred the interior lubricant oil of oilhole along with pump shaft rotates, its working principle such as same waterwheel.On the one hand, the centrifugal force that the disc of high speed rotating produces can get rid of to bearing being stored in the lubricant oil that stirs in the oilhole, thereby makes bearing keep good lubricating.On the other hand, its rotation can ceaselessly be stirred lubricant oil, is beneficial to the heat radiation of lubricant oil.Certainly, in order to cooperate the oil lubrication mode, the bearing support of original grease lubrication also should be done some adaptive changes, for example increases drain oil, oil ga(u)ge etc.
The present invention can utilize existing butter back-up ring, and it is transformed and can use, and original physical dimension need not changed.
The present invention is applicable to various types of slag stock pumps or other all kinds of rotating equipments, adopts technology of the present invention can guarantee bearing under oil lubrication or grease lubrication condition, can both obtain good lubricating.
In sum, the invention has the beneficial effects as follows: the first, the present invention is that improvement design is carried out on the basis with the existing standard accessory, does not change the quantity and the external dimension of accessory, can realize between new and old technology exchanging fully.The second, when adopting oil lubrication or grease lubrication, stable, performance efficiently that the technology of the present invention can have.The 3rd, design has intention, and accessory processing is simple.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing:
As shown in Figure 3, be a kind of bearing unit structural representation of slag stock pump.Plug screw 7 that have tank filler sleeve 6 on the bearing support 1, is used to drain the oil and the plug screw 8 that has dipstick.The shaft shoulder place of pump shaft 9 respectively establishes a disc 2.The end cap 4 of each side, labyrinth seal 5 and disc 1 form a bearing chamber, and bearing 3 is positioned at bearing chamber.Wherein disc 1, and its card is discoid.On the disc face of disc, evenly be provided with a plurality of run through its thickness stir oilhole 10, its opening is respectively towards two end faces of disk.In arbitrary plane perpendicular to the disc axis of disc card, these centers of stirring oilhole all are on the same center circle.Each axis that stirs oilhole all has an inclination angle with respect to the axis of disc, and these stir oilhole near the opening end of disc axis all in the same end face of disc, away from the opening end of disc axis all in another end face of disc.Two discs are installed in opposite directions, on each disc stir oilhole away from a side of disc axis towards the bearing chamber of a side separately.
When adopting oil lubrication, contain the lubricant oil of certain depth in the bearing support.Disc floodlubrication oil certain depth, lubricant oil enter and stir oilhole and store up in the hole and stay.The disc band to store up to stay and is stirred the interior lubricant oil of oilhole along with pump shaft rotates.The centrifugal force that the disc of high speed rotating produces will be stored in the lubricant oil that stirs in the oilhole and get rid of to bearing, thereby make bearing keep good lubricating.In addition, the rotation of disc can ceaselessly be stirred lubricant oil, helps the heat radiation of lubricant oil.
