Abstract
The utility model designs a leak-proof bearing bush and a long-shaft vertical draining pump transmission body. The bearing bush is provided with an inner surface and an outer surface, a fitting surface on which a self-aligning roller bearing is sleeved and a supporting surface on which a self-aligning thrust roller bearing is sleeved are formed on the outer surface, a plurality of slant through holes for communicating the inner surface with the outer surface are uniformly distributed in the circumference of the bearing bush, an annular groove is formed in the inner surface and communicated with the slant through holes; according to the bearing bush, most pressure of lubricating oil between the sleeve and the bearing bush can be efficiently removed, the lubricating oil is capable of flowing into the self-aligning roller bearing through the slant through holes as far as possible, the bearing can be lubricated more sufficiently, the possibility that the lubricating oil flows out of an oil tank is reduced, and the environment pollution degree is greatly reduced.
Description
Technical field
The utility model relates to fluid device, specifically, and a kind of leakage-proof type bearing housing and transmission body.
Background technique
As Fig. 1, rolling bearing can generate heat in the unit operation process, and the temperature in fuel tank is along with rising, and internal pressure is greater than ambient pressure.Under the acting in conjunction of pressure and centrifugal force, lubricant oil in fuel tank upwards flows along sleeve pipe, the selfaligning roller bearing of a part above the ejection of the hole of 4-φ 8 is used for lubricating, another part continues upwards to flow to the fuel tank outside in the gap between sleeve pipe and bearing housing along sleeve pipe, so just causes unnecessary waste., if or conveying is other clean liquid of tap water, so, lubricant oil also may flow in medium, causes certain pollution.
The model utility content
The utility model purpose is the problem that overcomes leakage of oil in prior art, proposes a kind of leakage-proof type bearing housing.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of leakage-proof type bearing housing, this bearing housing has an inner face and an outside, sheathed fitting surface and supplies the sheathed supporting surface of a self-aligning thrust roller bearing for a selfaligning roller bearing to be formed with one on this outside, circumferentially be evenly distributed with the oblique through hole of this inner face of a plurality of connections and this outside on this bearing housing along it, it is characterized in that, also be formed with an annular groove and this annular groove on this inner face and be connected with those oblique through holes.
The quantity of this oblique through hole is 4, and diameter is 8mm.
The groove width of this annular groove is greater than the aperture of this oblique through hole.
The utility model also provides a kind of long-axis vertical type water discharging pump transmission body, comprise, axle, fuel tank, selfaligning roller bearing, self-aligning thrust roller bearing, seal ring, fuel tank cap, axle sleeve, sleeve pipe and above-mentioned bearing housing, wherein, this axle sleeve is located in the inner face of this bearing housing, this selfaligning roller bearing is sheathed on the fitting surface of this bearing housing, and this self-aligning thrust roller bearing is sheathed on the supporting surface of this bearing housing.
Compared with prior art, advantage of the present utility model: (1) is by casting or process most of pressure that a circle groove releases the lubricant oil of flowing through between sleeve pipe and bearing housing, make flow through the as much as possible lubricated top selfaligning roller bearing in hole of 4-φ 8 of lubricant oil, reduced widely leakage rate; (2) selfaligning roller bearing is lubricated more fully; (3) reduce lubricant oil and flowed to the outer possibility of fuel tank, reduced to a great extent the contaminated degree of environment.
The accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the utility model centre bearer bush.
Fig. 3 is the structural representation of transmission body in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 2 and 3, shown in figure is a kind of long-axis vertical type water discharging pump transmission body, mainly by axle 4, fuel tank 9, selfaligning roller bearing 5, self-aligning thrust roller bearing 6, seal ring 8, fuel tank cap 2, axle sleeve 3, sleeve pipe 7 and bearing housing 1 form, wherein, this bearing housing 1 has an inner face 11 and an outside 12, sheathed fitting surface 121 and supplies the sheathed supporting surface 122 of a self-aligning thrust roller bearing 6 for a selfaligning roller bearing 5 to be formed with one on this outside 12, circumferentially be evenly distributed with along it oblique through hole 13 that 4 φ 8 are communicated with this inner face 12 and this outside 12 on this bearing housing, also being formed with an annular groove 14 and this annular groove on this inner face 11 is connected with those oblique through holes 13.This axle 4 is sheathed in the inner face 11 of this bearing housing, and this selfaligning roller bearing 5 is sheathed on the fitting surface 121 of this bearing housing 1, and this self-aligning thrust roller bearing 6 is sheathed on the supporting surface 122 of this bearing housing 1.
Pump is in operation process, nearly all lubricant oil of flowing through all converges in this groove, and then spill to lubricate selfaligning roller bearing 5 through oblique through hole 13, and even avoid the generation of leaking thereby reduce, greatly reduce the contaminated possibility of fed sheet of a media and surrounding environment.More energy-conservation, the more environmental protection of our pump like this.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
