The invention discloses an electrically-driven
gear transmission plunger pump. The electrically-driven
gear transmission plunger pump comprises a motor, a small-tooth-difference speed reducing transmission mechanism and a
plunger pump body, the input end of the small-tooth-difference speed reducing transmission mechanism is connected with an output shaft of the motor, and the output end of the small-tooth-difference speed reducing transmission mechanism eccentrically rotates and is connected with a
plunger pump core in the
plunger pump body to drive the
plunger pump core to do vertical reciprocating
linear motion in the plunger pump body. Therefore, the motor, the speed reducing mechanism and the plunger pump body are combined to complete mechanical-electrical-hydraulic integration, advantages and disadvantages are complementary, the structures are skillfully combined, parts are reduced, the cost is reduced, the functions are integrated, application is convenient, and the application range field is greatly widened; the structure is compact, the size is small, and the position precision is high; and the small-tooth-difference speed reducing transmission mechanism skillfully drives the plunger pump core to do
reciprocating motion, a tedious output mechanism is omitted, the industry
model selection and product development process is greatly and professionally shortened, and the electrically-driven
gear transmission plunger pump is especially suitable for vehicles, air vehicles, small
robot fixtures and the like.
