Abstract
Provided is a combined pump cover-type rotor oil pump, comprising a combined pump cover 1, an external rotor 2, an internal rotor 3, a pump shaft 4, a bolt 5, an oil sealing 6 and a tooth-shaped belt pulley 7. The pump shaft 4 is mounted in a shaft hole of the combined pump cover 1. The tooth-shaped belt pulley 7 is disposed at the outer end of the pump shaft 4, the internal rotor 3 and the external rotor 2 sleeved outside are disposed at the inner end, and a pump-shaft small head 41 for installation is disposed at the tail end. In the utility model, due to the adoption of the engine large-area end-cover component structure with the oil pump and the main shaft hole being integrated, the defect of oil leakage at an end face can be eliminated. The combined pump cover-type rotor oil pump of the utility model has the characteristics of compact structure, easy installation, convenient maintenance, small space occupation, stable operation, low noise, etc., and can further enhance the technical lever of matching and manufacturing engine components, increase the overall technical content of the components, lay a good foundation for advancement of the engine assembling and the integral structure and greatly reduce the manufacture cost.
Description
Technical field
The utility model relates to a kind of engine lubrication system parts, particularly a kind of combination pump cover formula rotor engine oil pump.
Background technique
Existing rotor engine oil pump all has pump cover, the pump housing, external rotor, internal rotor and pump shaft.In order to promote engine component progressively to develop to polynary combination and modularization direction, press for the rotor engine oil pump that oil pump and engine body end cap are integrated, be the needs that adapt to market development and reduce the motor cost.
Summary of the invention
The purpose of the utility model provides the combination pump cover formula rotor engine oil pump that a kind of oil pump and body end cap are integrated; Its compact structure, easy mounting, easy to maintenance, good in integrity; So that further promote the sealing and the manufacture level of motor; Improve the quality of product of complete machine, reduce the cost of production of complete machine.
The technological scheme of the utility model is: a kind of combination pump cover formula rotor engine oil pump; Form by combination pump cover, external rotor, internal rotor, pump shaft, bolt, oil sealing and toothed belt wheel; Pump shaft is installed in the axis hole of combination pump cover; Toothed belt wheel is equipped with in the outer end of pump shaft, and the external rotor of internal rotor and outside suit is equipped with in the inner, and end is provided with the pump shaft microcephaly who is used to install.
The further technological scheme of the utility model is: pump shaft is arranged on the upper left side of combination pump cover, and the terminal pump shaft microcephaly of its external rotor, internal rotor and pump shaft all exposes the outer end at combination pump cover attachment face.
The further again technological scheme of the utility model is: the middle below of combination pump cover 1 also is provided with spindle hole.
The utility model compared with prior art has following characteristics:
1, owing to adopt this oil pump and the combined integrated motor large size end cap modular construction of spindle hole, can eliminate the defective of end face leakage of oil.
2, further promote the technical merit that engine part is supporting and make, improve the whole technology content of part,, and can reduce manufacture cost greatly for motor assembling and integrally-built advance lay the foundation.
3, the utility model compact structure, easy mounting, easy to maintenance, occupy little space, turn round steadily, noise is little.
Further describe below in conjunction with accompanying drawing and embodiment detailed structure the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional drawing of Fig. 1 A-A.
Embodiment
Like Fig. 1, shown in 2: a kind of combination pump cover formula rotor engine oil pump; Form by combination pump cover 1, external rotor 2, internal rotor 3, pump shaft 4, bolt 5, oil sealing 6 and toothed belt wheel 7; Pump shaft 4 is installed in the axis hole of combination pump cover 1; Toothed belt wheel 7 is equipped with in the outer end of pump shaft 4, and the external rotor 2 of internal rotor 3 and outside suit is equipped with in the inner, and end is provided with the pump shaft microcephaly 41 who is used to install; Pump shaft 4 is arranged on the upper left side of combination pump cover, and its external rotor 2, internal rotor 3 and pump shaft 4 terminal pump shaft microcephalies 41 all expose in the outer end of combination pump cover attachment face, and the middle below of combination pump cover 1 also is provided with spindle hole 11.During installation, after locating through pump shaft 4 terminal pump shaft microcephalies 41 earlier, the combination pump cover that will assemble external rotor 2 and internal rotor 3 again is installed in the rotor hole and axis hole of body end face.
