Description
Technical field
The utility model is related to a kind of engine oil pumps.
Background technology
In current engine, the lubricant passage way of engine is mainly a lubricant passage way, i.e., lubricating oil pump is that complete machine is each
System provides lubricating condition.But in the racing car of part, while being promoted to engine performance, also studied from another point of view,
Reduce engine power loss, then independently divides chamber lubrication just to come into being, i.e., engine designs two independent lube systems
System.One each train of mechanism of lubrication engine is responsible for extraction crankcase inner engine oil for another and is taken away in time using independent oil circuit
Extra machine oil in crankcase reduces power loss；
Traditional birotor fuel pump structure passes through babinet by an axis, is arranged in the left and right crankcase of internal combustion engine two
Side, since two rotors are separately distributed, in babinet both sides, integrated model span is big, and the space for needing engine larger meets mechanism
Assembly be a kind of obstruction for the development of existing lightweight, compact engine.Also, traditional birotor fuel pump structure
By lubricating oil pump axis connection, left and right babinet both sides are distributed in, all components are separately mounted on babinet, then pass through both sides cover board
Seal both sides lubricating oil pump；Since such topology layout is inside engine housing, the air-tightness of single lubricating oil pump can not be detected.
Meanwhile traditional birotor fuel pump structure is integrally assemblied on engine housing, the peace of processing and lubricating oil pump for babinet
Reload request is higher, especially when occurring foreign matter in oil circuit, is transported at lubricating oil pump, lubricating oil pump can be caused to damage, while can lead to babinet
Damage.
Utility model content
The purpose of this utility model is just to provide engine oil pump a kind of compact-sized and with two sets of independent rotors.
The purpose of this utility model is that technical solution in this way is realized, a kind of engine oil pump, the machine oil
Pump includes oil pump body A and oil pump body B, and the oil pump body A and oil pump body B are oppositely arranged and connect, in the machine oil
The outer end face of pump housing B is provided with oil pump cover plate, and rotor mechanism is respectively arranged in the oil pump body A and oil pump body B,
The oil pump shaft of rotor mechanism is provided through in the lubricating oil pump oil pump body A and oil pump body B.
Wherein, the rotor mechanism includes the lubricating oil pump outer rotor A being arranged in oil pump body A and internal rotor of lubricating pump A,
And the lubricating oil pump outer rotor B and internal rotor of lubricating pump B, the internal rotor of lubricating pump A being arranged in oil pump body B are set in machine
In oil pump outer rotor A, the internal rotor of lubricating pump B is set in lubricating oil pump outer rotor B；Described oil pump shaft one end passes through lubricating oil pump
Internal rotor A and penetrate internal rotor of lubricating pump B.
Further, oil pump shaft moves axially in order to prevent, is arranged across one end of internal rotor of lubricating pump B in the oil pump shaft
Organic oil pump baffle ring.
It is positioned for the ease of assembly, at the outer of the oil pump body B is provided through oil pump body B and one end and machine
The positioning pin of oil pump body A connections.
By adopting the above-described technical solution, the utility model has smart structural design, using reliable, low-cost
Advantage is gathered two rotors using it and is integrated so that integrated model is compact, is effectively utilized the space of engine；Meanwhile it can
Air-leakage test is individually carried out, ensure that reliability, also, it can independently assemble replacement, it is therefore prevented that damage to babinet.
Description of the drawings
The description of the drawings of the utility model is as follows：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1：As shown in Figure 1, a kind of engine oil pump, the lubricating oil pump includes oil pump body A1 and oil pump body
B2, the oil pump body A1 and oil pump body B2 are oppositely arranged and connect, organic in the outer end face setting of the oil pump body B2
Oil pump cover board 3 is respectively arranged with rotor mechanism in the oil pump body A1 and oil pump body B2, in the lubricating oil pump lubricating oil pump
The oil pump shaft 4 of rotor mechanism is provided through in body A1 and oil pump body B2.
Wherein, the rotor mechanism includes the lubricating oil pump outer rotor A5 and internal rotor of lubricating pump being arranged in oil pump body A1
A6, and the lubricating oil pump outer rotor B7 and internal rotor of lubricating pump B8, the internal rotor of lubricating pump A6 that are arranged in oil pump body B2
It is set in lubricating oil pump outer rotor A5, the internal rotor of lubricating pump B8 is set in lubricating oil pump outer rotor B7；The oil pump shaft 4 one
End is across internal rotor of lubricating pump A6 and penetrates internal rotor of lubricating pump B8.
Further, one end of internal rotor of lubricating pump B8 is provided with lubricating oil pump baffle ring 9 in the oil pump shaft 4.
Positioned for the ease of assembly, be provided through at the outer of the oil pump body B2 oil pump body B2 and one end with
