Abstract
The invention discloses a cycloidal rotor pump which is characterized by comprising a driving shaft, an inner rotor, an outer rotor, a pump shell, an oil inlet chamber and an oil outlet chamber, wherein the outer side of the driving shaft is provided with the inner rotor; the outer side of the inner rotor is provided with the outer rotor; the pump shell surrounds the outer side of the outer rotor; and an oil inlet and an oil outlet are connected with the pump shell. According to the invention, through the rotation of the inner rotor and the outer rotor, the aims of oil absorption and oil exhaust are realized through changing the size of the working volume.
Description
Technical field
The present invention relates to a kind of cycloid rotor pump.
Background technique
All there is complex structure in most of oil pumps of producing in the market, in shortcomings such as high rotating speed run time behaviour are not good.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of cycloid rotor pump in order to solve the deficiency of existing technology.
Technological scheme: in order to realize above purpose; A kind of cycloid rotor pump of the present invention; It is characterized in that: comprise live axle, internal rotor, external rotor, pump case, oil suction chamber, go out oil pocket, the outside of described live axle is provided with internal rotor, and described external rotor is in the outside of internal rotor; Described pump case is centered around the external rotor outside, described oil suction chamber and go out the active chamber that forms between oil pocket and described internal rotor, the external rotor and be connected.
Beneficial effect: cycloid rotor pump provided by the invention has simple in structure, well behaved advantage during high speed operation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein 1, live axle, 2, internal rotor, 3, external rotor, 4, pump case, 5, oil suction chamber, 6, go out oil pocket.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
A kind of cycloid rotor pump as shown in Figure 1; It is characterized in that: comprise live axle 1, internal rotor 2, external rotor 3, pump case 4, oil suction chamber 5, go out oil pocket 6; The outside of described live axle 1 is provided with internal rotor 2; Described external rotor 3 is in the outside of internal rotor 2, and described pump case 4 is centered around external rotor 3 outsides, described oil suction chamber 5 and go out the active chamber that forms between oil pocket 6 and described internal rotor 2, the external rotor 3 and be connected.During the motor operation, drive oil pump inner and outer rotors 3 rotation in the same direction, internal rotor 2 is initiatively, slow 1 tooth of rotating ratio internal rotor 2 every circles of external rotor 3.The flank profil of the flank profil of internal rotor 2 and external rotor 3 is a pair of conjugate curve; It can be guaranteed when oil pump turns round; No matter where inner and outer rotors 3 forwards to, each tooth all is in engagement, thereby between internal rotor 2, external rotor 3, is formed at the active chamber of internal rotor 2 number of teeth same number.The volume of these active chambers constantly changes along with the rotation of rotor, and when rotor rotated toward the clockwise direction, the volume of each active chamber on internal rotor 2, external rotor 3 center line right sides changed from small to big, so that forms parital vacuum, and working oil is sucked from filler opening; Each active chamber in the left side of internal rotor 2, external rotor 3 center lines has greatly and diminishes, the working procedure that working oil is changeed pump from the oil outlet cycloid of discharging that Here it is.Because the rotor of engagement in cycloid rotor pump adopts, so that the designs simplification of oil pump.And, also guaranteed the stability of machine when high speed operation owing to be gear driven work.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
