Abstract
The utility model discloses a bearing box for a centrifugal pump, relating to the centrifugal pump; a box body is arranged, a bearing is arranged in the box body, a pump shaft is arranged in the bearing, and a bearing pressure cover is arranged on the box body on the outer side of the bearing; the bearing box is characterized in that an oil slinger is arranged on the pump shaft on one side of the bearing in the box body, wherein a constant-position oil cup which is communicated with the inside of the box body is arranged on the box body. While working, the pump shaft rotates and oil driven by the bearing axially flows to the back surface of the oil slinger, under the action of centrifugal force, the oil is dropped to the side wall of the bearing box body and reflows to an oil tank along the inner wall to form a self-lubricating and cooling system; the bearing has a large lubricating area and good lubricating effects, and the contact area of the lubricating oil and the bearing is large, so that the cooling effect to the bearing is good, the service life of the bearing is long, and the possibility that the oil flows out along the axial direction is prevented. A constant-position oil cup for complementing the lubricating oil is designed on the bearing body, and after the lubricating oil in the bearing box is lost by various reasons, the lubricating oil flows to the bearing box body inside the constant-position oil cup, so that the loss of the lubricating oil is timely and automatically complemented.
Description
Technical field
The utility model relates to centrifugal pump, says it is that a kind of bearing that makes can both obtain enough lubricated, coolings in any operating mode in detail, the centrifugal pump pump bearing case of lubricated, good cooling results.
Background technique
We know that the bearing in the centrifugal pump bearing parts is to be used for the supporting rotor part, and bear the various load that act on the rotor component; Lubricated main purpose is the loss that reduces to rub, and reduces or prevents wearing and tearing, also plays cooling, absorbing, effect such as antirust simultaneously.Existing centrifugal pump bearing case is to be provided with casing, is provided with bearing in the casing, is provided with pump shaft in the bearing; The casing in the bearing outside is provided with bearing gland, and casing is provided with tank filler sleeve and oil level indicator, in bearing housing, adds an amount of lubricant oil through tank filler sleeve; When axial workpiece rotated, bearing drove the lubricant oil rotation, because of the deadweight and the little reason of centrifugal force of oil; The lubricated area of bearing is little, lubrication effect is poor; Lubricant oil only contacts with the bearing small size, and is poor to the cooling effect of bearing, and the working life of bearing is short.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned existing technology, and a kind of centrifugal pump bearing case to bearing lubrication, good cooling results is provided.
The technological scheme that the utility model solves the problems of the technologies described above employing is: a kind of centrifugal pump bearing case; Be provided with casing; Be provided with bearing in the casing, be provided with pump shaft in the bearing, the casing in the bearing outside is provided with bearing gland; The pump shaft that it is characterized in that casing inner bearing one side is provided with disc, casing be provided with casing in the permanent position lubricating cup that is connected.
During work, the oil that the pump shaft rotation is taken up by bearing flows to the back side of disc vertically, under centrifugal action; Get rid of doff and hold on the box body sidewall, flow back to fuel tank, formed a kind of selflubricating, cooling system along inwall; The lubricated area of bearing is big, high lubricating effect, and the area that lubricant oil contacts with bearing is big, to the good cooling results of bearing; The long service life of bearing, and the possibility that has stoped oil to flow out vertically.When oil thrower was with the axle high-speed rotation in addition, the oil gas that is got rid of formed annular barrier one, has also stoped oily axial motion, plays the effect of motive sealing; On bearing support, designed the permanent position lubricating cup of compensation lubricant oil; Because a variety of causes and after the loss, the oil level in the casing descends, because law of connected vessels when the lubricant oil in the bearing housing; The oil level at place, lubricating cup inclined-plane, permanent position is reduced to below the working oil site; Cause the pressure balance of permanent position lubricating cup inner fluid to be destroyed, lubricant oil flows out into bearing housing in the lubricating cup of permanent position, guarantees the loss of lubricant oil is carried out in time replenishing automatically.
Description of drawings

Embodiment
The centrifugal pump of band lubricating and cooling as shown in the figure; Be provided with casing 5; Be provided with bearing 1,6 in the casing 5, be provided with pump shaft 3 in the bearing 1,6, the casing in bearing 1,6 outsides is provided with bearing gland; The pump shaft of casing 5 inner bearings 1,6 one sides is provided with disc 2,4, casing be provided with casing in the permanent position lubricating cup 7 that is connected.During work, the oil that the pump shaft rotation is taken up by bearing flows to the back side of disc vertically, under centrifugal action; Get rid of the inboard of falling side cover, flow back to fuel tank, formed a kind of selflubricating, cooling system along inwall; The lubricated area of bearing is big, high lubricating effect, and the area that lubricant oil contacts with bearing is big, to the good cooling results of bearing; The long service life of bearing, and the possibility that has stoped oil to flow out vertically.When oil thrower was with the axle high-speed rotation in addition, the oil gas that is got rid of formed annular barrier one, has also stoped oily axial motion, plays the effect of motive sealing; On bearing support, designed the permanent position lubricating cup of compensation lubricant oil; Because a variety of causes and after the loss, the oil level in the casing descends, because law of connected vessels when the lubricant oil in the bearing housing; The oil level at place, lubricating cup inclined-plane, permanent position is reduced to below the working oil site; Cause the pressure balance of permanent position lubricating cup inner fluid to be destroyed, lubricant oil flows out into bearing housing in the lubricating cup of permanent position, guarantees the loss of lubricant oil is carried out in time replenishing automatically; Cross when low when oil level in the lubricating cup of permanent position, in the lubricating cup of permanent position, add lubricant oil and get final product.
