Abstract
The utility model discloses an FGE00-type engine oil pump. A pump cover is installed on the end surface at the inner side of a pump body, a transmission shaft is installed inside a shaft hole of the pump body and the pump cover, the outer end of the transmission shaft is provided with a transmission gear, the middle part of the transmission shaft is provided with an inner rotor, and an outer rotor is sleeved on the inner rotor; an oil inlet is arranged beneath the pump cover, an oil inlet hole is arranged beneath the pump body, the tail end of the pump body is provided with an oil outlet hole, and an oil inlet cavity and an oil outlet cavity are arranged between the inner rotor and the outer rotor; and the oil inlet is respectively communicated with the oil inlet hole on the pump body and the oil inlet cavity between the inner rotor and the outer rotor, the oil outlet hole is communicated with the oil outlet cavity through a pressure limiting valve part which is arranged on the tail end of the pump body, and the oil outlet hole is also connected with an oil channel of an engine. Due to the adoption of the FGE00-type engine oil pump, an intermediate gear transmission accessory and a lubricating system can be saved, an engine oil pump appearance structure, an installation position, an oil inlet channel and an oil outlet channel are improved, and a main shaft gear of the engine is used for not only driving a transmission gear of the engine oil pump but also for driving an air pump gear.
Description
Technical field
The utility model relates to the engine lubrication system technical field, particularly a kind of FGE00 type oil pump.
Technical background
Existing a kind of motor is to adopt the kind of drive separately to oil pump parts and air pump parts: the one, and the mainshaft gear oil pump that direct transfers, the 2nd, mainshaft gear passes through carrier gear two kinds of structures of transmission air pump gear again.Its deficiency is: increased the part of a cover carrier gear transmission system and the weight of complete machine; Simultaneously; Difficulty and the manufacture cost of haveing suffered transmission system have also been increased to carrier gear lining lubrication system; Reduce the safety coefficient of normal working of engine, also wasted the useful horsepower of motor self simultaneously.
Summary of the invention
The utility model technical problem to be solved is to provide to the existing existing problem of oil pump a kind of FGE00 type oil pump of novel structure; This FGE00 type oil pump is removed carrier gear driven accessary and lubrication system from; Oil pump form structure, mounting point and turnover oil duct are improved, utilize mainshaft gear not only driver oil pump gear but also transmission air pump gear.
The utility model technical problem to be solved can realize through following technological scheme:
A kind of FGE00 type oil pump; Comprise pump cover, the pump housing, external rotor, internal rotor, transmission shaft, driving gear and pressure-limit valve parts, it is characterized in that said pump cover is installed on the inboard end face of the said pump housing; Said transmission shaft is installed in the axis hole of the said pump housing and pump cover; Said driving gear is equipped with in the outer end of transmission shaft, and the middle part is equipped with said internal rotor, is set with external rotor on the said internal rotor; The below of said pump cover is provided with filler opening, and the below of the said pump housing is provided with oil inlet hole, and the tail end of the said pump housing is provided with oil outlet, is provided with oil suction chamber between the said inside and outside rotor and goes out oil pocket; Said filler opening respectively with the pump housing on oil suction chamber between oil inlet hole and the inside and outside rotor be communicated with, said oil outlet goes out oil pocket and is communicated with said through the said pressure-limit valve parts that are arranged on the said pump housing tail end, said oil outlet is connected with the oil duct of motor.
The further technological scheme of the utility model is: the interior edge face of said pump cover is the benchmark attachment face, and the end face of said oil outlet becomes 66.6 ° of angles with the central axis of said transmission shaft, so that be connected with main oil conduit.
The important technological parameters of the FGE00 oil pump of the utility model is: when the oil pump rotating speed is 3600r/min, and when outlet pressure is 0.55MPa, flow >=55L; Its pressure limiting valve opening pressure is 0.65 ± 0.05MPa under equal rotating speed.
The utility model compared with prior art has following characteristics:
The utility model has been removed carrier gear driven accessary and lubrication system from, and oil pump form structure, mounting point and turnover oil duct etc. are improved, and the mainshaft gear that utilizes motor is the driving gear but also the transmission air pump gear of driver oil pump not only.Owing to reduced the part of a cover gap bridge driving gear, reduced the manufacture cost of motor, saved this partly steel again; Simultaneously can also improve engine health coefficient and useful horsepower.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A generalized section of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the detailed structure of the utility model is done further to describe.
As depicted in figs. 1 and 2: FGE00 type oil pump; Comprise pump cover 1, the pump housing 2, external rotor 3, internal rotor 4, transmission shaft 5, driving gear 6 and pressure-limit valve parts 7; The interior edge face 8 of pump cover 1 is the benchmark attachment face; Pump cover 1 is installed on the end face 9 of the pump housing 2 inboards, and the interior edge face 8 of pump cover 1 cooperates with the pump housing 2 inboard end faces 9.
The below of pump cover 1 is provided with filler opening 12, and the below of the pump housing 2 is provided with oil inlet hole 13, and the tail end of the pump housing 2 is provided with oil outlet 14, inside and outside rotor 4, is provided with oil suction chamber 15 between 3 and goes out oil pocket 16; Filler opening 12 respectively with the pump housing 2 on oil inlet hole 13 and inside and outside rotor 4, the oil suction chamber 15 between 3 be communicated with; Oil outlet 14 through be arranged on the pump housing 2 tail ends pressure-limit valve parts 7 with go out oil pocket 16 and be communicated with; 18 one-tenth 66.6 ° of angles of the end face 17 of oil outlet 14 and the central axis of transmission shaft 5 are so that be connected with main oil conduit.
