Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 It is a schematic diagram of the overall structure of the present invention. figure 2 It is a schematic diagram of the flexible internal gear structure. image 3 It is a schematic diagram of the flexible planetary gear structure.

[0019] Such as figure 1 As shown, the specific embodiment of the present invention includes: the power drives the central gear 5 to rotate through the transmission shaft, and the central gear 5 drives the flexible planetary gear 4 to move. The inner hollow of the flexible planetary gear 4 forms a closed space with the end covers on both sides of the pump. The flexible planetary gear 4, the pump casing 1, the central gear 5 and the end covers on both sides also form a closed space.

[0020] The distance between the approximately elliptical flexible internal gear 2 and th...

Abstract

The invention provides a technical scheme for a flexible gear pump. According to the scheme, the flexible gear pump comprises a pump shell, a flexible inner gear body, a flexible planet gear, a centergear, a connection key and a flow allocating hole. The technical problems that common pumps are divided into blade pumps, plunger pumps and gear pumps, the blade pumps and the plunger pumps are complicated in structure and high in price, the gear pumps are simple and compact in structure, and low in price, and thus are widely popularized, but the defects that gear pumps in the prior art are largein noise, large in flow pulsation, large in leakage amount and the like limit the application range of the gear pumps are solved. The technical scheme for the flexible gear pump has the beneficial effects that the structure is simple, machining is easy, the separated type structure facilitates installing and maintaining, cost is low, self pressure sealing between teeth can be achieved, leakage isreduced, symmetrical distribution is achieved, and the lateral force is reduced. In the running process, the flexible planet gear is in continuous and uniform deformation, flow fluctuation is reduced, and the beneficial effects that the blade pumps are large in displacement, high in pressure level and the like are achieved.

Description

technical field [0001] The invention relates to a hydraulic pump, in particular to the technical field of a flexible gear pump. Background technique [0002] In the prior art, common pumps are divided into vane pumps, plunger pumps, and gear pumps. Vane pumps and plunger pumps are complex in structure and expensive, while gear pumps are simple in structure, compact in structure and low in price, so they are widely used. However, the gear pump in the prior art has disadvantages such as high noise, large flow pulsation, and large leakage, which limit the application range of the gear pump. Contents of the invention [0003] In view of the above problems, the present invention provides a flexible gear pump. [0004] A flexible gear pump according to the present invention includes a pump casing, a flexible internal gear, a flexible planetary gear, a central gear, a connecting key, and a flow distribution hole. It is characterized in that: the flexible internal gear is detach...
