Abstract
The utility model relates to an oil pump, in particular to a novel oil pump with a double-layer structure. The novel oil pump with the double-layer structure comprises a pump body, gears, a driving shaft and an idle shaft. The novel oil pump with the double-layer structure is characterized in that the pump body is in the structure of an upper layer and a lower layer which are divided by a baffle plate, an inner cavity of the pump body at the upper layer and an inner cavity of the pump body at the lower layer are respectively provided with a pair of gears, and the gears are engaged and are connected in a transmission way; an oil inlet hole and an oil outlet hole are respectively arranged on the pump body at the upper layer and the pump body at the lower layer; and a transmission gear is respectively installed on the driving shaft coaxially and in the inner cavity of the pump body at the upper layer and the inner cavity of the pump body at the lower layer. The functions of two oil pumps are realized on one oil pump. A large amount of transmission elements and engine spaces are saved.
Description
Technical field
The utility model relates to oil pump, particularly a kind of novel double-layer structure oil pump.
Background technique
Prior art middle gear pump has only a pair of gear, and the rotation by gear, extrudes machine oil from oil outlet in the machine oil suction pump from oil inlet hole again, finishes the fuel feeding work of pump.How to be implemented in the function that realizes two oil pump on the oil pump, and to require two kinds of different output flows are provided respectively, this is a new research topic.
The model utility content
The purpose of this utility model is at the problems referred to above, and a kind of two-in-one machine oil pump is provided.
The technical solution of the utility model is a novel double-layer structure oil pump, comprises the pump housing, gear, driving shaft and lazy axle, it is characterized in that the described pump housing is the upper and lower layers structure that dividing plate separates, and upper and lower layers pump housing inner chamber is respectively installed a pair of gear and is meshed and is in transmission connection; On upper strata and lower floor's pump housing, respectively be provided with oil inlet hole and oil outlet.
Coaxial each driving gear of upper and lower layers pump housing inner chamber that is installed on the described driving shaft.
The utility model has the advantages that because the upper strata of oil pump separates with dividing plate with lower floor, thus be equivalent to work at the same time in the platform oil pump, and also the upper and lower have the turnover oilhole respectively.Because design is unique novel, an oil pump replaces two pumps, has saved between a large amount of transmission component and engine air.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1,1-driving shaft, 2-upper strata driving gear, 3-dividing plate, 4-lower floor driving gear, the 5-pump housing.
As shown, innovative point of the present utility model is that the pump housing is set to the upper and lower layers structure of separating with dividing plate, and upper and lower layers pump housing inner chamber is respectively installed the connection that is meshed of a pair of gear, respectively is provided with oil inlet hole and oil outlet on upper strata and lower floor's pump housing.For this reason, on driving shaft 1, two driving gears of coaxial installation, i.e. upper strata driving gear 2 and lower floor's driving gear 4.Another gear that is meshed with driving gear is installed on the lazy axle.Concrete working principle: on the driving shaft 1 driving gear is installed, the rotating power of motor is reached on the upper strata driving gear 2 and lower floor's driving gear 4 that connects with driving shaft, thereby driving the gear that connects the all-in-one-piece the upper and lower with driving shaft rotates simultaneously, because the upper strata of oil pump separates with dividing plate 3 with lower floor, work at the same time so be equivalent to two oil pump.5 is pump housings among the figure, and the upper and lower have the turnover oilhole respectively.
Claims (2)
1. novel double-layer structure oil pump comprises the pump housing, gear, driving shaft and lazy axle, it is characterized in that the described pump housing is the upper and lower layers structure that dividing plate separates, and upper and lower layers pump housing inner chamber is respectively installed a pair of gear and is meshed and is in transmission connection; On upper strata and lower floor's pump housing, respectively be provided with oil inlet hole and oil outlet.
2. by the described novel double-layer structure of claim 1 oil pump, it is characterized in that coaxial each driving gear of upper and lower layers pump housing inner chamber that is installed on the described driving shaft.
