Abstract
The utility model discloses an oil pump provided with double gears. The oil pump comprises a front pump body, wherein the rear side of the front pump body is connected with a rear pump body through a connecting plate; a front pump driving gear and a front pump driven gear are rotationally mounted in the front pump body; a rear pump driving gear and a rear pump driven gear are rotationally mounted in the rear pump body; and the rear end of the front pump driving gear and the front end of the rear pump driving gear are in transmission connection to form a whole through a cross joint in the connecting plate. The oil pump provided with the double gears has higher transmission efficiency, and occupies small space.
Description
Technical field
the utility model relates to oil pump field, is specially a kind of duplicate gear oil pump.
Background technique
Gear oil pump is applicable to carry the various liquid that has lubricity, the kind of drive in the single oil pump of prior art mostly is single-stage driving gear and drives single-stage driven gear, and efficiency of transmission is low, must adopt a plurality of oil pump series connection to coordinate in the time of need to improving efficiency of transmission, the space that installation takies is larger, complex structure.
Model utility content
The purpose of this utility model is to provide a kind of duplicate gear oil pump, to solve the low problem of prior art oil pump single gear transmission efficiency of transmission.
In order to achieve the above object, the technological scheme that the utility model adopts is:
Duplicate gear oil pump, it is characterized in that: include the front pump housing, front pump housing installed in front has protecgulum, front pump housing rear side is connected with the rear pump housing by connecting plate, the moving front pump driven gear that front pump driving gear is installed and meshes with front pump driving gear of front pump housing transfer, the rear pump driving gear that is rotatablely equipped with rear pump driven gear in the rear pump housing and meshes with rear pump driven gear, described front pump driving gear rear end, rear pump driven gear front end stretches into respectively in connecting plate, and front pump driving gear rear end, rear pump driven gear front end is in transmission connection and is integrated by cross shaped joint in connecting plate.
Described rear pump housing rear side is provided with the bonnet of the rear pump housing of sealing by bolt.
Described front pump driving gear passes from protecgulum, and is provided with oil sealing between front pump driving gear and protecgulum inwall.
The utility model has the advantages that:
The utility model adopts forward and backward pump driving gear to drive respectively the duplex drive mechanism of forward and backward pump driven gear, forward and backward pump driving gear is in transmission connection by cross shaped joint, while needing, can increase cross shaped joint and realize multilevel transmission structure expansion, there is higher efficiency of transmission, and it is little to take up room.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
