Abstract
The invention relates to a novel self-lubricating self-sealing bearing Y-type oil pump which comprise a pump body, an impeller which is arranged in the pump body, a pump cover, a bearing box which is connected with the pump cover, impeller shafts which drive the impeller to rotate and a back pressing cover which is used for sealing the bearing box. The novel self-lubricating self-sealing bearing Y-type oil pump is characterized in that the pump body, the pump cover and the inner portion of the bearing box are communicated, a first sliding bearing is sleeved on the impeller shaft which is arranged in the pump cover, and a second sliding bearing is sleeved on the impeller shaft which is arranged in the bearing box. The novel self-lubricating self-sealing bearing Y-type oil pump has the advantages of simplifying a pump body structure, reducing manufacturing cost, lightening pump body weight and achieving lubrication circulation and sealing effect of the inner portion of a pump.
Description
Technical field
The present invention relates to Y type oil pump, particularly a kind of novel self-lubricating selfsealings bearing Y type oil pump.
Background technique
Y type oil pump is all cantilever structure usually, be that driving end has the bearing chamber of dual-gripper to join rolling bearing, then cantilever end band impeller, sometimes pump is larger, will add axle thicker when outstanding length is larger, impact is larger concerning the Hydraulic Design part of impeller like this, and material and space are all relatively wasted simultaneously.In actual moving process, because cantilevered structure has been doomed the front surface impeller part larger amount of deflection of bearing portion generation relatively, also will produce relatively large vibrations, so the bracketed part of the choma position of impeller and axle all can wear and tear comparatively fast.The lubricated of bearing is to lean on the thin oil of bearing chamber to provide simultaneously, and the thin oil of grease chamber itself just need to have oil sealing.The sealing of pump chamber is to realize by conventional machinery or packing seal usually, so whole structure is more complicated.And such structure also need to add the cooling normal operation that guarantees each several part on its pump housing, in sealing and position, bearing grease chamber to the higher oil of delivery temperature the time.
Summary of the invention
The present invention seeks to overcome many deficiency factors of prior art, proposed a kind of novel self-lubricating selfsealings bearing Y type oil pump.
The present invention is achieved in that a kind of novel self-lubricating selfsealings bearing Y type oil pump, comprise: the impeller in the pump housing, the pump housing, pump cover, the bearing housing that is connected with pump cover, the impeller shaft of drives impeller rotation and the rear pressing cover of stuffing box bearing case, it is characterized in that: the described pump housing, pump cover and bearing housing inside communicate, be arranged with the first sliding bearing on impeller shaft in pump cover, be arranged with the second sliding bearing on the impeller shaft in bearing housing.
The bearing shell of described the second sliding bearing is the combination bearing shell, and the end face that contacts with this combination bearing shell at bearing housing is groove surface, and the combination bearing shell is embedded in groove surface, and the neck bush of the second sliding bearing is located on impeller shaft.
The neck bush of described the first sliding bearing is located on impeller shaft, and its bearing shell matches with pump cover.The material of described the first sliding bearing, the second sliding bearing is pottery or cemented carbide.
Also comprise a fan, this fan is set on the impeller shaft at rear pressing cover rear and follows impeller shaft and rotate together.
Advantage of the present invention: simplify pump body structure, reduce manufacture cost, alleviate pump housing weight, realize the effect of the circulation of pump internal lubrication and sealing.
Description of drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Fig. 3 is enlarged diagram of the present invention.
Below in conjunction with drawings and Examples, the present invention is elaborated.
Embodiment
The main points of this creation are exactly to adopt brand-new bearing arrangement mode and structure, reach and simplify this body structure of pump, realize the effect of the circulation of pump internal lubrication and sealing.
A kind of novel self-lubricating selfsealings bearing Y type oil pump, comprise: the impeller in the pump housing, the pump housing, pump cover, the bearing housing that is connected with pump cover, the impeller shaft of drives impeller rotation and the rear pressing cover of stuffing box bearing case, it is characterized in that: the described pump housing, pump cover and bearing housing inside communicate, realize being connected with pump chamber, be arranged with the first sliding bearing on impeller shaft in pump cover, be arranged with the second sliding bearing on the impeller shaft in bearing housing.Because pumped medium itself mostly is oil, possessed good greasy property (even be clear water, also good self lubricity can be arranged), and realize the combination of sliding bearing and end face seal at it by driving end one side, reach and to do the bearing bearing radial force and also can do and seal the function that realizes end face seal.The part that wherein plays the end face sealing does not re-use spring and replenishes as the compression of sealing, and the axial force of utilizing pump impeller itself to produce realizes that the compression that seals compensates (producing axial force as cancelling equalizing orifice).And for pump structure own, allow it that larger axial displacement of relative original structure axially can be arranged, and no longer consider to go the axial force of balance impeller generation, can simplify some parts again.
The bearing shell of described the second sliding bearing is the combination bearing shell, and the end face that contacts with this combination bearing shell at bearing housing is groove surface, and the combination bearing shell is embedded in groove surface, and the neck bush of the second sliding bearing is located on impeller shaft.
The neck bush of described the first sliding bearing is located on impeller shaft, and its bearing shell matches with pump cover.
The material of described the first sliding bearing, the second sliding bearing adopts hardness higher and widely used stupalith or Hardmetal materials (WC/SiC etc.), its advantage is that material itself has good hardness and intensity, be widely used in bearing and machine envelope, and can bear high temperature, can be in the situation that high temperature add cooling to this part.
Also comprise a fan, this fan is set on the impeller shaft at rear pressing cover rear and follows impeller shaft and rotate together.
Below only expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
