Fig. 1-5 is please referred to, the utility model provides a kind of technical solution:

A kind of gear conveying oil pump, as shown in Figure 1, Figure 2 and Figure 3, including oil pump body 1, the inside of oil pump body 1 are equipped with Oil storage cavity 11 is fixedly installed with postposition shell 2 on the trailing flank of oil pump body 1, is equipped in postposition shell 2 and places chamber 21, It is fixedly installed with oil inlet pipe 12 on oil pump body 1 and is fixedly installed with flowline 13, oil inlet pipe 12 and flowline 13 are equal It is connected with oil storage cavity 11.

Specifically, the cavity wall of oil storage cavity 11 is equipped with the through-hole for allowing the second shaft 34 to pass through, each second shaft 34 is Through-hole in 11 cavity wall of oil storage cavity.

Further, postposition shell 2 is made of stainless steel, and stainless steel material rigidity is high, is hardly damaged, benefit In prolonging its service life.

As shown in Figure 1, Figure 2, it shown in Fig. 3, Fig. 4 and Fig. 5, places and is equipped with oil mass conveying device 3, oil mass conveying device in chamber 21 3 include being fixedly mounted on the servo motor 31 placed on 21 bottom wall of chamber, is closely welded with master on the output shaft of servo motor 31 Moving gear 32, the side of driving gear 32 is equipped with driven gear 33, and driving gear 32 and driven gear 33 are intermeshed, driven It is fixedly installed with first rotating shaft 331 on the one side of gear 33, and is rotated between first rotating shaft 331 and the cavity wall for placing chamber 21 The second shaft 34, each second shaft 34 are fixedly installed on the same side of connection, driving gear 32 and driven gear 33 On be respectively mounted there are two symmetrical sealing ring 35, two sealing rings 35 in same second shaft 34 are located at storage The two sides of through-hole in oily 11 cavity wall of cavity are equipped in each second shaft 34 and set blade 36 and underlying blade 37, above set Blade 36 and underlying blade 37 are respectively positioned in oil storage cavity 11.

The explanation of value, servo motor 31 is using the production of Beijing A Wode automation equipment Co., Ltd MOTEC Series AC servo, matched circuit and power supply are also provided by the producer；In addition, involved in the utility model It is the prior art to servo motor 31, those skilled in the art's work may be implemented completely, it is not necessarily to superfluous words, the utility model protection Content is not related to the improvement to the structure and working principle of servo motor 31 yet.

The section that blade 36 and underlying blade 37 are set on it is worth noting that, is arc-shaped, and on set blade 36 and underlying Blade 37 is adapted with the size of oil storage cavity 11, blade 36 and underlying blade 37 is set in guarantee in the rotation, with storage Perfect cooperation between the cavity wall of oily cavity 11 further realizes the conveying to oil.

Oil inlet pipe 12 when in use, is connected extraneous oil pipe, at the same time by servo by the gear conveying oil pump of the present embodiment Motor 31 connects extraneous power supply, and servo motor 31 is started to work, and the output shaft on servo motor 31 starts turning, and drives close weldering The driving gear 32 connect on it rotates, and when driving gear 32 rotates, drives and its intermeshing driven gear 33 Rotation drives two the second shaft 34 rotations, due to driving gear when driven gear 33 and driving gear 32 rotate 32 with driven gear 33 be it is intermeshing, therefore driving gear 32 with the rotation direction of driven gear 33 be it is opposite, therefore two The rotation direction of a second shaft 34 be it is opposite, when the oil in extraneous oil pipe enters in oil inlet pipe 12, and smoothly flow into When to oil storage 11 inside of cavity for above setting blade 36 and the top of underlying blade 37, at this time since two the second shafts 34 are constantly turning It is dynamic, two underlying 37 rotation directions of blade on the contrary, two underlying beginnings of blades 37 are contacted with the cavity wall of oil storage cavity 11, and along The cavity wall of oil storage cavity 11 moves upwards, and sets blade 36 on two at this time and starts to move downward, and due to setting leaf on one of them The position that piece 36 is installed is located at the lower section that 36 installation site of blade place plane is set on another, therefore realizes and set on one of them Blade 36 can first be moved downward than setting blade 36 on another, and during setting blade 36 on two and moving downward, on two The surface for setting blade 36 is contact, and oil is contained on two by guarantee to be set between blade 36, while avoiding setting blade on two It is mutually collided between 36, during setting blade 36 on two and moving downward, realization will set the oil between blade 36 on two It is fed down in flowline 13, is to be adapted with the size of oil storage cavity 11 due to above setting blade 36 and underlying blade 37 , guarantee that oil can only could be conveyed by above setting the rotation of blade 36 and underlying blade 37, oil is avoided to set blade 36 and storage from above It flows out in gap between oily 11 side wall of cavity, or is flowed from the gap between 11 side wall of underlying blade 37 and oil storage cavity Out, when two underlying blades 37 are rotated up, the motion state of two underlying blades 37 with two on set blade 36 Motion state is the same, therefore realizes the uninterrupted conveying to oil, additionally, due to setting blade 36 and two underlying blades 37 on two Between without squeezing action power, and then avoid setting on two between blade 36 and two underlying blades 37 and wear, solve general Gear pump after long-time use, internal gear is due to the state that is in engagement for a long time and squeezes, gear surface Be easy to wear, once and after serious wear, efficiency the problem of will be greatly reduced of conveying oil.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
