Hydraulic gear pump capable of efficiently damping

Abstract

The hydraulic gear pump comprises a pump body, an oil inlet pipe is fixedly connected to the front side of the pump body, an oil outlet pipe is fixedly connected to the rear side of the pump body, a driving shaft is connected to the left side wall of the pump body in a penetrating mode, the tail end of the driving shaft extends into the pump body, and a flowing cavity is formed in the pump body; the two ends of the flowing cavity are fixedly connected with the oil inlet pipe and the oil outlet pipe correspondingly. According to the gear pump, shaking generated in the meshing transmission process of the driving gear and the driven gear is primarily damped through the buffer pad and the damping springs, vibration is equally distributed in the radial direction through the buffer pad and the damping springs arranged in the circumferential direction at equal intervals, and primary damping of vibration during working of the gear pump is achieved; amplitude after primary damping is transmitted to the first damping sleeve so that vibration can be transmitted in the axial direction, secondary damping is achieved through the multiple elastic damping ribs, double damping protection in the axial direction and the radial direction is achieved, and the damping effect is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic gear pumps, in particular to a high-efficiency shock-absorbing hydraulic gear pump. Background technique [0002] The hydraulic gear pump is a kind of hydraulic oil through the mutual meshing between the gears to realize the volume change inside the closed chamber formed by the pitch of the gear and the gear groove, and then realize the pressure difference between the oil inlet pipe and the oil outlet pipe of the gear pump, so as to achieve Therefore, hydraulic gear pumps are widely used in various construction machinery and equipment due to their large speed range during transmission, impact load resistance, convenient maintenance, and low price. [0003] The existing hydraulic gear pumps have the following technical defects in use: First, since the torque transmission core of the gear pump is realized by the meshing of the driving gear and the driven gear, there is a large shaking between the ...

Problems solved by technology

[0003] The existing hydraulic gear pumps have the following technical defects in use: First, since the torque transmission core of the gear pump is realized by the meshing of the driving gear and the driven gear, there is a large shaking between the gears during the transmission process , easily lead to damage to the hydraulic gear pump; second, the existing damping device of the hydraulic gear pump has a single damping mode, and most of them can only achieve axial damping, but cannot achieve radial damping, and the damping effect is poor
