The present invention compared with prior art has following characteristics:
1, the variable rotor engine oil pump of impeller regulation and control provided by the invention has realized that the oil flow rate of transporting to the motor oil duct can change according to the needs of motor, when having guaranteed normal working of engine in the needed fuel delivery, can not make the machine oil in the motor oil duct too much, influence the Economy and the reliability of motor.
2, can change according to the rotating speed of motor and regulate oil flow rate, make the oil pressure in the motor oil duct can relax adjusting, reduce the impact that brings because of the oil pressure acute variation, can effectively protect motor.
3, because oil inlet quantity and the oil pump capacity of taking the mode of directly adjusting to regulate internal rotor, external rotor have reduced the engine oil pressure that oil pocket, thereby reduced the transporting resistance of machine oil, reduced the power consumption of oil pump.
Below in conjunction with the drawings and specific embodiments detailed structure of the present invention is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the A-A sectional view in the accompanying drawing 1.
Embodiment
A kind of variable rotor engine oil pump of impeller regulation and control, it is made up of the pump housing 1, pump cover 2, impeller regulation and control ring 3, external rotor 4, internal rotor 5, transmission shaft 6, spring 7 and safety valve parts 8.Impeller regulation and control ring 3 and spring 7 are installed in the impeller annular distance 16 and spring slotted eye 15 on the pump housing 1, transmission shaft 6 middle parts and internal rotor 5 interference fit, and be installed to the impeller regulation and control in the lump together with external rotor 4 and encircle in the axis hole of intermediate hole on 3 and the pump housing 1, pump cover 2.Impeller annular distance 16 both sides in the pump housing 1 and bottom surface are provided with oil suction chamber 14 and go out oil pocket 11 and oil road 12 and oil outlet 13, and its oil outlet 13 communicates with the oil duct of motor.The outside of impeller regulation and control ring 3 is provided with leaf valve 31 and return valve 32, the area on leaf valve 31 two sides does not wait, its A face is greater than the B face, when the two sides is subjected to uniform pressure, because the A face bears unit pressure greater than the B face, so pressure oil just can promote the leaf valve 31 in impeller regulation and control ring 3 outsides to oil suction chamber 14 directions, reach the engagement orientation of regulation and control internal rotor 5, external rotor 4 and realize purpose oil-feed, oil extraction flow control.The oil road 12 of the pump housing 1 is provided with safe valve opening 85, and safe valve opening 85 communicates with oil road 12, is provided with draining hole 84 in the passage of safe valve opening 85.Be provided with safety valve parts 8 in the safe valve opening 85, safety valve parts 8 are made up of steel ball valve 81, Regulation spring 82 and regulating screw 83, and steel ball valve 81 is on the passage that withstands on safe valve opening 85 and oil road 12 under the spring force effect of Regulation spring 82.Pump cover 2 junction planes are provided with oil input channel 22 and filler opening 21, and filler opening 21 communicates with oil header, and oil input channel 22 is communicated with the oil suction chamber 14 of the pump housing 1.The pump housing 1 and pump cover 2 link together by bolt, the pump housing 1 is with after pump cover 2 is connected by bolt, oil input channel 22 communicates with oil suction chamber 14, and oil suction chamber 14, go out oil pocket 11 and distribution is all arranged in the bottom surface and the outside of impeller regulation and control ring 3 and internal rotor 5, external rotor 4, make and can enter the machine oil that the slit is located between internal rotor 5, the external rotor 4 or flow out to oil suction chamber 14 and go out oil pocket 11.
The variable rotor engine oil pump of impeller regulation and control provided by the invention is to have increased an impeller regulation and control ring 3 and spring 7 on traditional rotor engine oil pump, this impeller regulation and control ring 3 is used the cycloidal-pin wheel principle, in rotary movement, regulate and control the tooth cavity 41 of internal rotor 5, external rotor 4 both engagements by eccentric angle and offset and regulate oil mass with the unlatching in advance of oil suction chamber 14 channel positions.
Its working principle is: transmission shaft 6 drives internal rotor 5, external rotor 4 rotates with counterclockwise, internal rotor 5, external rotor 4 is opened gradually at oil suction chamber 14 positions, and the space that both mesh formation along sense of rotation increases gradually, produce certain degree of vacuum, be drawn into machine oil in the tooth cavity 41 of oil suction chamber 14 and both engagements from oil header, along with rotor continues rotation, the machine oil of rotor tooth cavity 41 has taken oil pocket 11 positions to, in rotor 5, when the tooth cavity 41 of external rotor 4 both engagements reduces gradually, machine oil will be sent to out oil pocket 11, deliver to again in each oil circuit of motor through oil road 12 and oil outlet 13, each motive position of motor is lubricated.
When motor when slowly running, engine oil pressure is low, its fuel delivery can satisfy lubricated requirement.Along with engine speed increases, from oil suction chamber 14 through internal rotor 5, the oil flow rate that the tooth cavity 41 that external rotor is 4 is transported to out oil pocket 11 also increases thereupon, the engine oil pressure that goes out oil pocket 11 rises, the pressure difference that goes out oil pocket 11 and oil suction chamber 14 is increasing, when the pressure at two ends difference acquires a certain degree, the leaf valve 31 that the pressure oil that goes out oil pocket 11 will promote impeller regulation and control ring 3 sides rotates to oil suction chamber 14 directions, after impeller regulation and control ring 3 turns an angle, will be with internal rotor 5, both tooth cavities 41 of meshing gradually of external rotor 4 close control in advance with oil suction chamber 14 passages, reduce the oil masses that tooth cavity 41 sucks in the oil suction chamber 14.Therefore, the oil mass of transporting to out oil pocket 11 from tooth cavity 41 also reduces in succession, goes out oil pocket 11 engine oil pressures and reduces, and the pressure of finally using oil pocket 11 and oil suction chamber 14 reaches balance, realizes the adjusting of fuel delivery.
When the impeller regulation and control encircle 3 when oil suction chamber 14 directions are rotated, return valve 32 holddown springs 7 on the impeller regulation and control ring 3, like this after the rotating speed of motor descends, oil suction chamber 14, go out oil pocket 11 engine oil pressure differences and reduce, impeller regulation and control ring 3 just can rely on the elastic force effect of spring 7 that return valve 32 is back into original position, recover normal oil transportation channel, make the engine oil pressure of motor oil duct can remain on certain level, guarantee the normal lubricated of motor.
When engine speed sharply increases; the engine oil pressure that goes out oil pocket 11 further increases; when impeller regulation and control ring 3 is promoted to rotate to the limit; pressure oil will be pushed the steel ball valve 81 in the safety valve 8 open; pressure oil in the oil road 12 is excreted out from draining hole 84, reach protection engine lubrication system safety.
When impeller regulation and control ring 3 when oil suction chamber 14 directions are rotated, the tooth cavity 41 of internal rotor 5, external rotor 4 both engagements closes gradually in advance with oil suction chamber 14 passages to be controlled.When impeller regulation and control ring 3 when going out oil pocket 11 directions and rotate, when the tooth cavity 41 of internal rotor 5, external rotor 4 both engagements recovers the normal position gradually with oil suction chamber 14.So just can change and regulate oil flow rate, make the oil pressure in the motor oil duct can relax adjusting, reduce the impact that brings because of the oil pressure acute variation, can effectively protect motor according to the rotating speed of motor.Owing to take directly to regulate internal rotor 5, external rotor 4 oil inlet quantities and oil pump capacity, reduce the mode that oil pocket 11 engine oil pressures, thereby reduced the transporting resistance of machine oil, reduced the power consumption of oil pump.
