Problems solved by technology

[0002] We know that the existing hydraulic power system includes a prime mover, a reducer and a hydraulic gear pump. The power output shaft of the prime mover is connected to the power input shaft of the reducer. The end of the power input shaft of the pump is provided with a power input gear, and a transmission is provided on the power output gear and the power input gear. The two ends of the transmission are respectively provided with inner ring gears, and the two inner ring gears are respectively connected with the power output gear and the power input gear. The gears are meshed. This transmission structure makes the concentricity error between the power output shaft of the reducer and the power input shaft of the hydraulic gear pump large, resulting in low overall performance and short service life.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] As shown in the figure, a power transmission device of a FRP marine gear pump is provided with a power output gear 7 at the end of the power output shaft 6 of the reducer 5, and a power input at the end of the power input shaft 2 of the hydraulic gear pump 1. The inner ring gear 4 and the power output gear 7 mesh with the power input inner ring gear 4, the power is directly transmitted from the power output shaft of the reducer to the power input shaft of the hydraulic gear pump, and the power output shaft of the reducer and the power of the hydraulic gear pump The coaxiality error of the input shaft is small, the overall performance is high, and the service life is long, and the structure of the transmission device is simple, and the manufacturing and use costs are low. A protective cover 3 is provided outside the meshing part of the power output gear and the p...

Abstract

The invention relates to hydraulic gear pumps, in particular to a power transmission device of a gear pump for ferry glass reinforced plastic boats. The power transmission device is simple in structure, convenient for connection and long in service life, and is characterized in that a power output gear is arranged at the end of a power output shaft of a speed reducer, a power input internal gear ring is arranged at the end of a power input shaft of the hydraulic gear pump, the power output gear is meshed with the power input internal gear ring, and a protecting cover is arranged outside the power output gear and the power input internal gear ring and used for preventing entering of dust or danger caused by accidental touch during operation. The power transmission device has the advantages that since the power output shaft of the speed reducer is in direct meshed connection with the power input shaft of the hydraulic gear pump via the gear and the internal gear ring, the power output shaft of the speed reducer and the power input shaft of the hydraulic gear pump are small in coaxiality error, and the power transmission device is high in integral performance, long in service life, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a hydraulic gear pump, in detail it is a power transmission device of a glass fiber reinforced plastic marine gear pump with simple structure, convenient connection and long service life. Background technique [0002] We know that the existing hydraulic power system includes a prime mover, a reducer and a hydraulic gear pump. The power output shaft of the prime mover is connected to the power input shaft of the reducer. The end of the power input shaft of the pump is provided with a power input gear, and a transmission is provided on the power output gear and the power input gear. The two ends of the transmission are respectively provided with inner ring gears, and the two inner ring gears are respectively connected with the power output gear and the power input gear. The gears are meshed. This transmission structure makes the coaxiality error between the power output shaft of the reducer and the power input shaft of the hydra...
