Abstract
The utility model relates to a rotor type engine oil pump, in particular to a rotor type engine oil pump adopting an engine main shaft for direct transmission. The rotor type engine oil pump consists of a pump body, a pump cover, an outer rotor and an inner rotor, wherein the outer rotor is arranged in a rotor hole of the pump body, the outer rotor is movably matched with the rotor hole of the pump body, the inner rotor is arranged in a die cavity of the outer rotor, the inner rotor is movably matched with the die cavity of the outer rotor, the pump cover is arranged on the pump body in the positions of the inner rotor and the outer rotor through screws, and the flexible rotation of the rotors needs to be ensured after the installation of the pump cover. Two symmetrical lug bosses with internal circular arcs in the middle are arranged on the inner wall of a shaft hole of the inner rotor, and the shaft hole of the inner rotor forms a flat square hole used for transmitting motive power.
Description
Technical field
The utility model relates to a kind of rotor-type oil pump, and particularly a kind of is to adopt the direct drive rotor-type oil pump of engine spindle.
Background technique
Existing oil pump mostly is to carry out transmission by modes such as gear, chain, cingulums, because the component of transmission system are more, increased this partly consumption of component material, and manufacturing man-hour and cost of production, the risk that this part part has an accident because of damage also increased simultaneously.In addition, these component have increased the weight of engine dry weight, have increased the loss of motor self power, and the engine energy-saving consumption reduction is brought serious unfavorable factor.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of employing engine spindle direct drive rotor-type oil pump, particularly aims at the supporting main shaft of the CA6GV h type engine h rotor-type oil pump that direct transfers.
The technical solution of the utility model is: a kind of main shaft rotor-type oil pump that direct transfers, it is made up of the pump housing, pump cover, external rotor, internal rotor.External rotor is located in the rotor hole of the pump housing, and the rotor hole of the external rotor and the pump housing adopts movingly.Internal rotor is located in the die cavity of external rotor, and the die cavity of internal rotor and external rotor adopts movingly.Pump cover is installed in by screw on the pump housing at inner and outer rotors position, and pump cover will guarantee that rotor rotation is flexible after installing.On the inwall of internal rotor axis hole, be provided with two symmetries in the middle of the boss of circular arc in the band, make flat square hole of axis hole formation of internal rotor, be used for transfer motion power.
The main shaft that the utility model the provides rotor-type oil pump that direct transfers is to aim at the supporting rotor-type oil pump of CA6GV h type engine h.During work, engine oil pump assembly is installed in the front end of engine body, and the flat side of engine spindle front end directly extend in the flat square hole of internal rotor, drives internal rotor and rotates.
The utility model compared with prior art has following characteristics:
1, the main shaft that provides of the utility model direct transfers rotor-type oil pump owing to adopt the direct drive mechanism of main shaft, has reduced the supporting driving parts of oil pump, has reduced the risk that has an accident, and has improved Security, reliability and the working life of oil pump.
2, the main shaft that provides of the utility model rotor-type oil pump that direct transfers has alleviated own wt owing to driving parts is few, has improved the output of engine power.
3, the main shaft that provides of the utility model rotor-type oil pump novelty simple in structure that direct transfers reaches saving of labor, material-saving, reduces cost and energy saving purposes.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
