Description
Technical field
The utility model oil pump belongs to motorcycle engine, dune buggy engine field, particularly relates to a kind of oil pump that is installed in the engine crankcase.
Prior art
Because there is the oil pump of various ways in present this field of China; usually oil pump is to drive a pair of rotor of engine oil pump motion by transmission shaft or drive chain in motor; its pump oil pressure of this oil pump is low, and the pump oil mass is little, can only satisfy the lubricated needs of mini engine.
The model utility content
The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of simple in structure, pump oil pressure height, the oil pump that the pump oil mass is big.
The purpose of this utility model is to reach by following measure, and it is A that oil pump body one, oil pump external rotor, oil pump internal rotor, needle roller, oil pump body two are formed a pump oil; It is B that oil pump body two, oil pump external rotor, oil pump internal rotor, needle roller, oil pump body three are formed a pump oil; It is C that oil pump body three, oil pump external rotor, oil pump internal rotor, needle roller, oil pump body four are formed a pump oil.
Pump oil is that B provides engine lubrication for independent oil path; Pump oil is that A and pump oil are that C has independently filler opening respectively, but has the oil outlet that unites two into one.The shared oil pump transmission shaft of whole engine oil pump assembly, the oil pump transmission shaft is connected with the oil pump sprocket wheel by flat side, and by bolton, the oil pump sprocket wheel links to each other with bent axle by the oil pump chain.
The oil pump sprocket wheel links to each other with bent axle by the oil pump chain, when engine crankshaft begins to rotate, driving oil pump chain and oil pump sprocket wheel turns round together, the oil pump sprocket wheel drives the rotation of oil pump transmission shaft, because the oil pump transmission shaft links to each other with three needle rollers, and then drive needle roller and three pairs of inside and outside rotor in oil pump rotate simultaneously.
The utility model is simple in structure, can satisfy the lubricated needs of the motorcycle engine of big discharge capacity, and the drive mechanism of oil pump is simple, is skillfully constructed, Perfect in shape and function.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the present utility model.
Embodiment
Be described further below in conjunction with a pair of the utility model of accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, the utility model oil pump is made up of following: oil pump external rotor 1, oil pump internal rotor 2, oil pump transmission shaft 3, needle roller 4, oil pump body 45, oil pump body 36, oil pump body 27, oil pump body 1, reduction valve machine 9, oil pump sprocket wheel 10, hexagon flange bolt 11, bolt 12, bolt 13, locating stud 14.
Wherein oil pump body one, oil pump external rotor, oil pump internal rotor, needle roller, pump oil of oil pump body two compositions are A, it is B that oil pump body two, oil pump external rotor, oil pump internal rotor, needle roller, oil pump body three are formed a pump oil, and it is C that oil pump body three, oil pump external rotor, oil pump internal rotor, needle roller, oil pump body four are formed a pump oil.
Choosing pump oil in this type is that B provides engine lubrication for independent oil path, and pump oil is that A and pump oil are that C has independently filler opening respectively, and pump oil is A filler opening 15, and pump oil is C filler opening 18, but oil outlet unites two into one oil outlet 17.Pump oil is B filler opening 16, and pump oil is B oil outlet 19.
The shared oil pump transmission shaft of engine oil pump assembly, the oil pump transmission shaft is connected with the oil pump sprocket wheel by flat side, and uses bolton; The oil pump sprocket wheel links to each other with bent axle by the oil pump chain.When engine crankshaft rotates, drive the rotation of oil pump chain and oil pump sprocket wheel, thereby drive the rotation of oil pump transmission shaft, and then drive needle roller and three pairs of inside and outside rotor in oil pump rotate simultaneously.Wherein, provide the main oil pump of engine lubrication to be, and adjust oil pump body oil inlet and outlet position as required simultaneously according to the optional pump oil of engine structure; Two pump oil are to flow to the radiator cooling after oil outlet unites two into one in addition.
Claims (3)
