Abstract
The utility model relates to an oil pump connection structure comprising a cam shaft assembly, an inner rotor and an outer rotor, wherein the cam shaft assembly comprises a cam and a rotor shaft, and an oil hole is formed in the rotor shaft; the inner rotor is arranged in the outer rotor; the lower end of the rotor shaft is provided with a D-shaped shaft; a central hole in the inner rotor is provided with a D-shaped hole matched with the D-shaped shaft; and the D-shaped shaft is arranged in the D-shaped hole of the inner rotor in a sleeving manner. According to the technical scheme provide by the utility model, the lower end of the rotor shaft is provided with the D-shaped shaft which is matched with the D-shaped hole inside the inner rotor, so that the installation is simple and convenient, a fixing step by utilizing a key or a pin is reduced as long as the D-shaped shaft is directly inserted into the D-shaped hole, the installation steps are reduced, and the oil pump connection structure is simple and practical.
Description
Technical field
The utility model relates to a kind of oil pump linkage structure, belongs to the technical field of structures of outboard machine.
Background technique
Rotor-type oil pump is made up of housing, internal rotor, external rotor and pump cover etc., internal rotor is fixed on the rotor shaft with key or pin, directly or indirectly driven by crankshaft gear, the throw of eccentric at internal rotor and external rotor center is e, and internal rotor drives external rotor and rotates in the same direction together, many one of the raised teeth number of the recessed gear ratio internal rotor of external rotor, the nonsynchronous in the same way rotation of inside and outside like this rotor, the gabarit pattern curve of rotor is trochoid, such project organization complexity, cost height.
The model utility content
The utility model purpose is that a kind of oil pump linkage structure simple in structure is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of oil pump linkage structure comprises cam assembly, internal rotor, external rotor; Described cam assembly comprises cam, rotor shaft, is provided with oilhole in the rotor shaft; Described internal rotor is installed in the external rotor; The D profile shaft is arranged in described rotor shaft lower end; Described internal rotor intermediate hole is arranged to the D type hole of matching with the D profile shaft; Described D profile shaft is sleeved in the D type hole of internal rotor.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of oil pump linkage structure of the utility model scheme, by the rotor shaft lower end being arranged to the use that matches of D type hole in the middle of D profile shaft and the internal rotor, simple and convenient when mounted, only need directly the D profile shaft to be inserted in the D type hole, reduced with key or the fixing step of pin, saved the step of installing, simple and practical.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of a kind of oil pump linkage structure of the present utility model;
Accompanying drawing 2 is that the inside and outside rotor of a kind of oil pump linkage structure of the present utility model cooperates figure;
Wherein: 1, cam assembly; 2, internal rotor; 3, external rotor; 4, cam; 5, rotor shaft; 6, oilhole; 7, D profile shaft; 8, D type hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
The utility model scheme is by being arranged to rotor shaft 5 lower ends the use that matches of D type hole 8 in the middle of D profile shaft 7 and the internal rotor 2, simple and convenient when mounted, only need directly D profile shaft 7 to be inserted in the D type hole 8, reduced with key or the fixing step of pin, saved the step of installing, simple and practical.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
