Abstract
The utility model provides a cycloid rotor pump. The cycloid rotor pump comprises a cycloid rotor, a linkage mechanism, an execution blank cap, and an oil inlet blank cap, wherein the linkage mechanism is sheathed outside the cycloid rotor and engaged with the cycloid rotor, the execution blank cap is sheathed outside the linkage mechanism and engaged with the linkage mechanism, the oil inlet blank cap is arranged at one side of the execution blank cap, and a plurality of groups of resistance textures are arranged on the cycloid rotor. The cycloid rotor pump has the advantages of being reasonable in design, large in power, high in working efficiency and the like.
Description
Technical field
The utility model relates to mechanical engineering technical field, is specifically related to cycloid rotor pump.
Background technique
Cycloid rotor pump is to utilize the variation of sealed volume between gear to realize that oil suction presses oil, it is by carrying out stifle, the oil-feed stifle, linking mechanism and the eccentric compositions such as cycloid rotor that are placed in the pump housing, linking mechanism and cycloid rotor differ a tooth, because linking mechanism and cycloid rotor are multiple tooth engagements, this has just formed some sealed volume, when cycloid rotor rotates around the center, drive linking mechanism and do rotation in the same way around the linking mechanism center, at this moment, by the rotation of the sealed volume that forms between cycloid rotor tooth top and linking mechanism tooth paddy along with cycloid rotor, sealed volume just enlarges gradually, so just form parital vacuum, fluid is inhaled into Seal cage from the oil-feed stifle, when cycloid rotor continues rotation, the sealed volume that is full of fluid just reduces gradually, fluid is squeezed, so oil is got rid of, when all meshing with the mark of mouth of linking mechanism to another tooth of cycloid rotor, pressure oil finishes, cycloid rotor whenever circles, finish suction by each sealed volume that cycloid rotor tooth top and linking mechanism tooth paddy constitute, press oil respectively once, when cycloid rotor rotates continuously, namely finished the suction oil work of oil hydraulic pump.Cycloid rotor pump has many advantages, as compact structure, volume is little, part is few, the rotating speed height, motion steadily, noise is low, volumetric efficiency is more high, shortcoming is the manufacturing process complexity of cycloid rotor etc., adopted the powder metallurgy pressing moulding at present, development along with industrial technology, the application of cycloid rotor pump will be more and more extensive, in addition, because the structural characteristics of cycloid rotor pump itself, its flow pulsation is bigger, thereby makes equipment be difficult to stable operation, simultaneously, because the surface of the cycloid rotor smooth structures that adopt, fluid promotion cycloid rotor rotates and need expend bigger power more.
Summary of the invention
Technical problem to be solved in the utility model is to provide cycloid rotor pump, simple in structure, make easy, reasonable in design, can reduce flow pulsation, make equipment operation more steady, can make that cycloid rotor is easier to be pushed, the required power that provides of fluid is provided.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: cycloid rotor pump, comprise cycloid rotor, be socketed in cycloid rotor outer with the cycloid rotor engagement linking mechanism, be socketed in the outer execution stifle that meshes with linking mechanism of linking mechanism, the oil-feed stifle that is located at execution stifle one side, described cycloid rotor is provided with some groups of resistance lines.
As preferably, described cycloid rotor adopts five teeth, thereby has reduced sealed volume, has reduced flow pulsation, makes the equipment operation more steady.
As preferably, respectively be provided with one group of resistance line on the both sides of described each tooth of cycloid rotor, thereby make cycloid rotor be more prone to be pushed, the required power that provides of fluid has been provided.
Beneficial effect:
The cycloid rotor pump that the utility model adopts technique scheme to provide, simple in structure, make easy, reasonable in design, can reduce flow pulsation, make equipment operation more steady, can make that cycloid rotor is easier to be pushed, the required power that provides of fluid has been provided.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, cycloid rotor 1, tooth 11, linking mechanism 2, execution stifle 3, oil-feed stifle 4, resistance line 5.
Embodiment
As shown in Figure 1, cycloid rotor pump, comprise cycloid rotor 1, be socketed in cycloid rotor 1 outer with cycloid rotor 1 engagement linking mechanism 2, be socketed in the outer execution stifle 3 that meshes with linking mechanism 2 of linking mechanism 2, the oil-feed stifle 4 that is located at execution stifle 3 one sides, described cycloid rotor 1 is provided with some groups of resistance lines 5, described cycloid rotor 1 adopts five teeth 11, respectively is provided with one group of resistance line 5 on the both sides of described cycloid rotor 1 each tooth 11.
During real work, cycloid rotor 1 adopts the design of five teeth 11 to reduce sealed volume, has reduced flow pulsation, make the equipment operation more steady, the design of resistance line 5 on the cycloid rotor 1 makes cycloid rotor 1 be more prone to be pushed, the required power that provides of fluid has been provided, has reduced energy consumption.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used cycloid rotor 1, tooth 11, linking mechanism 2, carried out terms such as stifle 3, oil-feed stifle 4, resistance line 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
