Problems solved by technology

During the working process of traditional external gear pumps and internal gear pumps, due to the uneven radial force and large flow fluctuations, noise will be generated, the life of the pump will be shortened, and the increase of the pump pressure level will be restricted. When large displacement is required In some cases, the volume of the pump is often large

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] refer to figure 1 , a double-connected three-gear internal meshing composite motor pump driven by a switched flux motor, including a motor stator 101, the motor stator 101 is fixedly connected to the motor casing 103, the motor casing 103 is solidly welded on the motor support 106, and the motor casing 103 is two The end is connected with a motor end cover 104, and is fixedly connected by a tension screw 105. The motor rotor 102 is a hollow structure inside, and the first outer ring gear 301 and the second outer ring gear 501 are embedded in the motor rotor 102 through a key connection. The ring gear 301 meshes with the first pinion 302, the first outer ring gear 301, the first pinion 302, and the first partition 303 are connected to form the first pump body, the second outer ring gear 501 meshes with the second pinion 502, The second outer ring gear 501, the...

Abstract

The invention discloses a duplex three-gear inner gearing compound motor pump driven by a switch flux motor. A motor rotor adopts a hollow structure; a first pump body composed of a first outer gear ring, a first pinion and a first partition board and a second pump body composed of a second outer gear ring, a second pinion and a second partition board are embedded in the motor rotor; the first pump body and the second pump body adopt inner gearing compound gear pumps and are connected in parallel to form a double-pump structure; the double-pump structure adopts the manner of oil feeding at two ends and oil discharging at one end; one side of each pump body is provided with an oil feeding oil distribution disc and an oil feeding end cover; an oil discharging oil distribution disc is arranged between two pump bodies. According to the invention, the pump bodies are embedded in the switch flux motor, so that the pumping capacity is increased, the pump flow pulsation is reduced, and the characteristic of high-pressure mass flow is easy to realize to enable the working performance to be safe and stable.

Description

technical field [0001] The invention belongs to the technical field of gear pumps, in particular to a double-connected three-gear internal meshing composite motor pump driven by a switch magnetic flux motor. Background technique [0002] The hydraulic gear pumps currently sold and used mainly have two structural forms, namely external gear pumps and internal gear pumps. During the working process of traditional external gear pumps and internal gear pumps, due to the uneven radial force and large flow fluctuations, noise will be generated, the life of the pump will be shortened, and the increase of the pump pressure level will be restricted. When large displacement is required In some cases, the volume of the pump is often large. [0003] In recent years, the hydraulic transmission system is developing in the direction of fast response, small volume, and low noise. direction of development. Scholars at home and abroad have used cascade gear pumps, balanced compound gear pu...
