Problems solved by technology
[0004] During the work of the gear pump, the two ends of the gear move relative to the pump body, accompanied by friction, which leads to serious wear between the gear and the inner wall of the pump body, which seriously affects the service life of the gear pump. If the body is made of wear-resistant materials, the production cost of the gear pump will be greatly increased, and the defects are obvious
[0005] In addition, since the distribution plate needs to carry the auxiliary shaft, the thickness of the distribution plate is relatively large, resulting in a large overall structural volume of the gear pump, which occupies a large space in the equipment, and is not convenient for the installation and fixing of the gear pump.

Embodiment Construction
[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.
[0023] Such as Figure 1 to Figure 4 As shown, a gear pump with a compact structure includes a pump body, a main shaft 1 installed in the pump body, and a counter shaft 2 installed in the pump body. The main shaft 1 and the counter shaft 2 are respectively provided with a main gear 3 and a counter gear 4 , the main gear 3 and the pinion gear 4 are meshed and connected, and the pump body is provided with an oil inlet 5 and an oil outlet 6, both of which extend to the junction of the main gear 3 and the pinion 4, the Two distribution plates 7 are installed in the pump body, and the main gear 3 and the auxiliary gear 4 are located between the two distribution plates 7. The pump body is provided...

The invention relates to the technical field of hydraulic transmission control and particularly relates to a compact structure type gear pump. The pump comprises a pump body, a main shaft and an auxiliary shaft, a main gear and a pinion are arranged on the main shaft and the auxiliary shaft respectively, two valve plates are installed inside the pump body, both the main gear and the pinion are located between the two valve plates, two installation holes which are used for installing the auxiliary shaft are arranged on the pump body, and two end portions of the auxiliary shaft are movably embedded into the two installation holes respectively. Valve plates are arranged, so that abrasion between the main gear and the pump body and between the pinion and the pump body is greatly reduced, and the service life of the compact structure type gear pump is prolonged; and two installation holes which are used for installing the auxiliary shaft are arranged on the pump body, most of the auxiliary shaft is carried by the pump body, and the thickness of valve plates is greatly reduced, so that the overall dimension of the compact structure type gear pump is reduced, the space that the pump occupies is small, and the pump is convenient to install.
Description
technical field [0001] The invention relates to the technical field of hydraulic transmission control, in particular to a compact gear pump. Background technique [0002] The hydraulic oil pump is composed of four parts: the pump body, the rectangular fuel tank, the pressure handle, and the ultra-high pressure steel wire braided rubber hose. The power component of the hydraulic system is used to convert the mechanical energy of the prime mover into the pressure energy of the liquid. , which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps and plunger pumps. [0003] The structure of the gear pump is relatively simple, that is, its most basic form is that two gears of the same size mesh with each other and rotate in a tightly fitted housing. The inside of the housing is similar to an "8" shape, and the two gears are installed inside. The outer diameter and both sides of the gear are closely match...
