Abstract
The invention provides a side plate structure. The side plate structure is simple and capable of effectively preventing the radial displacement of a side plate and a pump body and guaranteeing the sealing performance of the side plate and the pump body. The side plate structure comprises a side plate body, wherein two gear shaft holes are formed in the side plate body, a sealing groove is formed in one side, corresponding to the gear shaft hole, of the side plate body, and the side plate structure is characterized in that at least two positioning bulges are formed in the side plate body.
Description
Technical field
The present invention relates to the technical field of gear pumps parts, be specially a kind of lateral plate structure.
Background technology
Gear pump is conventional a kind of power set, its operation principle is to be closed space in rotation by two gears at two at gear pump, the change relying on the swept volume formed between pumping cylinder and meshing gear improves the pressure of liquid and realizes the conveying of liquid, side plate is the critical component realizing high-pressure gear pump turnover oil, whether the structure of side plate rationally directly affects quality and the performance of whole element, side plate to be connected with the pump housing, existing side plate is that monoplane is connected with the pump housing, this connected mode can produce the radial displacement of side plate and the pump housing, thus have impact on the sealing property of side plate and the pump housing.
Summary of the invention
For the problems referred to above, the invention provides a kind of lateral plate structure, its simple in construction, effectively prevent the radial displacement of side plate and the pump housing, it is ensured that the sealing property of side plate and the pump housing.
Its technical scheme is such that a kind of lateral plate structure, it includes side plate plate body, being provided with two gear shaft holes on described side plate plate body, corresponding described gear shaft holes side is provided with seal groove, it is characterised in that: at least provided with two positioning convex on described side plate plate body.
It is further characterized by described side plate plate body to be provided with three positioning convex, and described positioning convex is separately positioned on side between described gear shaft holes outer end and described gear shaft holes.
In the said structure of the present invention, due on side plate plate body at least provided with two positioning convex, when positioning convex is connected with the pump housing, realizes location by positioning convex, effectively prevent the radial displacement of side plate and the pump housing, it is ensured that the sealing property of side plate and the pump housing.
Accompanying drawing explanation
Fig. 1 is side plate front view of the present invention；
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
See Fig. 1, Fig. 2, a kind of lateral plate structure, it includes side plate plate body 1, side plate plate body 1 is provided with gear shaft holes 2-1,2-2, corresponding gear axis hole 2-1,2-2 side is provided with seal groove 3, side plate plate body 1 is provided with three positioning convex 4, positioning convex 4 is separately positioned on side between gear shaft holes 2-1,2-2 outer end and gear shaft holes 2-1,2-2, during installation, when positioning convex is connected with the pump housing, realize location by positioning convex, effectively prevent the radial displacement of side plate and the pump housing, it is ensured that the sealing property of side plate and the pump housing.
In the present embodiment; positioning convex 3 is separately positioned on side between gear shaft holes 2-1,2-2 outer end and gear shaft holes 2-1,2-2; certain positioning convex can also be arranged on other positions; as long as arrange at least two positioning convex; when achieving side plate installation; the radial direction achieving side plate and the pump housing positions, and is all the scope of protection of the invention.
Claims (2)
