Description
Technical field
The utility model relates to oil pump technical field, especially a kind of biaxial plane oil pump assy.
Background technique
Because present oil pump requires more and more higher, simultaneously more and more higher to the sae number requirement of oil pump.Existing part oil pump is all hoisting power on the basis of original power, does not redesign oil duct.In order to increase oil pump fuel delivery, can only increase rotor thickness, cause the supporting surface of oil pump rotating shaft fewer and feweri, cause oil pump rotating shaft serious wear.
Summary of the invention
In view of this, the utility model provides a kind of life-span long, the biaxial plane oil pump assy that performance is good and easy to assembly
A kind of biaxial plane oil pump assy, comprise the pump housing, pump cover and driving gear, pump cover covers on the pump housing, on the pump housing, have axocoel, driving shaft and driven shaft are arranged in axocoel, pump cover is provided with oil suction chamber and goes out oil pocket, on the pump housing, be provided with described oil suction chamber and go out filler opening and the oil outlet that oil pocket is corresponding, driving gear is arranged on outside the pump housing, is provided with woodruff key on driving shaft, and described driving gear is connected by woodruff key with main shaft, it is characterized in that, the described pump housing and pump cover are provided with axle sleeve, and driving shaft is through in axle sleeve, and gear is housed in axocoel.
As the further improvement of this programme, described driving shaft is connected with large driving gear and small active gear.
As the further improvement of this programme, on described driving shaft, be provided with woodruff key, small active gear is connected by woodruff key with main shaft.
As the further improvement of this programme, described driven shaft is connected with large driven gear and little driven gear.
As the further improvement of this programme, described driving gear is added with locking nut outward and fixes.
The beneficial effects of the utility model are, on the pump housing of this engine oil pump assembly and pump cover, are equipped with axle sleeve, can effectively reduce the frictional force between the pump housing, pump cover and pump shaft three.By adopting driving shaft and driven shaft, reduce the burden of driving shaft in running, also can increase the fuel delivery of oil pump simultaneously, eliminate because the fewer and feweri heavy wear that causes oil pump rotating shaft of supporting surface of oil pump rotating shaft.Drive driven gear by driving gear, thereby drive the operation of driven shaft, the loss of having saved the energy.The utlity model has the features such as simple in structure, reasonable in design, low cost of manufacture.

Embodiment 1
As shown in Figure 1, a kind of biaxial plane oil pump assy that the utility model provides, comprise the pump housing 2, pump cover 1 and driving gear 10, pump cover 1 covers on the pump housing 2, on the pump housing, have axocoel, driving shaft 4 and driven shaft 6 are arranged in axocoel, pump cover 1 is provided with oil suction chamber and goes out oil pocket, on the pump housing 2, be provided with described oil suction chamber and go out filler opening and the oil outlet that oil pocket is corresponding, driving gear 10 is arranged on outside the pump housing 2, on driving shaft 4, be provided with woodruff key, described driving gear 10 is connected by woodruff key 8-1 with main shaft 4, it is characterized in that, the described pump housing 2 and pump cover 1 are provided with axle sleeve 9, driving shaft 4 is through in axle sleeve 9, gear is housed in axocoel.
Further improve, described driving shaft 4 is connected with large driving gear 5-1 and small active gear 5-2.
Further improve, on described driving shaft 4, be provided with woodruff key, small active gear 5-2 is connected by woodruff key 8-2 with main shaft 4.
Further improve, described driven shaft 6 is connected with large driven gear 7-1 and little driven gear 7-2.
Further improve, the outer locking nut 3 that is added with of described driving gear 10 is fixed.
Rotating shaft is through in axle sleeve can effectively reduce the frictional force between the pump housing, pump cover and pump shaft three.Driving shaft and driven shaft are housed in axocoel, in the situation that not increasing between gear and axle surface of contact, have increased the fuel delivery of oil pump.Large driven gear is connected with large driving gear, and drives driven gear by large driving gear, then drives driven shaft, has further saved energy loss, has improved the utilization efficiency of oil pump.The utlity model has the features such as simple in structure, reasonable in design, low cost of manufacture.
Utilize technological scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designs similar technological scheme, and reaching above-mentioned technique effect, is all to fall into protection domain of the present utility model.
