Abstract
The utility model discloses a vane pump which comprises a pump body, a pump cover, a spindle, a pump core and an oil distribution disc, wherein the pump cover is fixedly arranged on the pump body; an inner cavity for accommodating the pump core and the oil distribution disc is formed between the pump body and the pump cover; the spindle penetrates through the pump cover; the pump core is sleeved on the spindle; the oil distribution disc is positioned between the pump core and the pump body; and a pressure spring is arranged between an end face at the other end of the oil distribution disc and the pump body. Therefore, in the long-term rotating process of the pump core along with the spindle, the oil distribution disc can be always kept to be tightly adhered to the pump core under the elastic compensation action of the pressure spring, so that lubricating oil on the oil distribution disc can be timely and effectively transferred to the pump core; and therefore, the pump core and the spindle are stable and smooth in transmission, and the generated noise is reduced.
Description
Technical field
The utility model relates to a kind of vane pump.
Background technique
Vane pump mainly comprises the pump housing, pump cover, main shaft, pump core, oil distribution casing; Pump cover is fixedly arranged on the pump housing, constitutes the inner chamber of ccontaining pump core and oil distribution casing between the pump housing and the pump cover, and main shaft is arranged in the pump cover; The pump core retainer plate is located on the main shaft, and oil distribution casing is between the pump core and the pump housing.Because the pump core is being followed the long-term rotation of main shaft; Gap between pump core and the oil distribution casing can slowly become greatly, thereby causes the oil on the oil distribution casing in time to be delivered on the pump core, thereby the transmission of causes pump core and main shaft occurs not steady; Even beat, and produce big noise.
Summary of the invention
To the deficiency of existing technology, the utility model provides the vane pump that a kind of stable drive is smooth and easy, noise is low.
For realizing above-mentioned purpose, the utility model provides a kind of vane pump, comprises the pump housing, pump cover, main shaft, pump core, oil distribution casing; Pump cover is fixedly arranged on the pump housing, constitutes the inner chamber of ccontaining pump core and oil distribution casing between the pump housing and the pump cover, and main shaft is arranged in the pump cover; The pump core retainer plate is located on the main shaft, and oil distribution casing is between the pump core and the pump housing, and an end end face and the pump core of oil distribution casing are close to; Be provided with holddown spring between the other end end face of oil distribution casing and the pump housing; Also be provided with many oil grooves that run through the two ends end face in the described oil distribution casing, an end of said oil groove is connected with the oil inlet and outlet of the pump housing, and the other end of said oil groove leads to the pump core.
The beneficial effect of the utility model is: adopt said structure; Because an end end face and the pump core of oil distribution casing are close to; Be provided with holddown spring between the other end end face of oil distribution casing and the pump housing; Therefore following in the long-term rotation process of main shaft at the pump core, oil distribution casing can remain under the elastic compensating effect of holddown spring and being close to of pump core, thereby makes the lubricant oil on the oil distribution casing can be delivered on the pump core timely and effectively; The transmission that makes pump core and main shaft is steady and smooth more, and the noise of generation also is reduced.
The utility model can further be set to also be provided with between described holddown spring and the oil distribution casing spring housing.
The utility model also can further be set to be provided with bearing between main shaft and the pump cover.

Fig. 1 is the structure sectional view of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of vane pump, comprised the pump housing 1, pump cover 2, main shaft 3, pump core 4, oil distribution casing 5, pump cover 2 is fixedly arranged on the pump housing 1; Constitute the inner chamber of ccontaining pump core 4 and oil distribution casing 5 between the pump housing 1 and the pump cover 2; Main shaft 3 is arranged in the pump cover 2, is provided with bearing 6 between main shaft 3 and the pump cover 2, and pump core 4 is sheathed on the main shaft 3; Oil distribution casing 5 is between the pump core 4 and the pump housing 1; The one end end face and the pump core 4 of oil distribution casing 5 are close to, and are provided with holddown spring 7 between the other end end face of oil distribution casing 5 and the pump housing 1, also are provided with spring housing 8 between described holddown spring 7 and the oil distribution casing 5.Also be provided with many oil grooves 51 that run through the two ends end face in the described oil distribution casing 5, an end of said oil groove 51 is connected with the oil inlet and outlet 11 of the pump housing 1, and the other end of said oil groove 51 leads to pump core 4.
Adopt said structure; Because an end end face and the pump core 4 of oil distribution casing 5 are close to, and are provided with holddown spring 7 between the other end end face of oil distribution casing 5 and the pump housing 1, therefore following in the long-term rotation process of main shaft 3 at pump core 4; Oil distribution casing 5 can remain under the elastic compensating effect of holddown spring 7 and being close to of pump core 4; Thereby make the lubricant oil on the oil distribution casing 5 to be delivered to timely and effectively on the pump core 4, the transmission that makes pump core 4 and main shaft 3 is steady and smooth more, and the noise of generation also is reduced.
Claims (3)
