Abstract
The utility model provides a kind of lateral plate structure, its structure is simple, effectively prevent the radial displacement of side plate and the pump housing, ensure that the sealability of side plate and the pump housing, it comprises side plate plate body, described side plate plate body is provided with two gear shaft holes, corresponding described gear shaft holes side is provided with seal groove, it is characterized in that: described side plate plate body is at least provided with two positioning convex.
Description
Technical field
The utility model relates to the technical field of gear pumps parts, is specially a kind of lateral plate structure.
Background technique
Gear pump is conventional a kind of power plant, its working principle is rotated in two enclosed spaces by two gears at gear pump, rely on the change of the swept volume formed between pumping cylinder and engaging gear to improve the pressure of liquid and to realize 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 the quality and performance of whole element, side plate will be connected with the pump housing, existing side plate and the pump housing are that single plane is connected, this Placement can produce the radial displacement of side plate and the pump housing, thus have impact on the sealability of side plate and the pump housing.
Summary of the invention
For the problems referred to above, the utility model provides a kind of lateral plate structure, and its structure is simple, effectively prevent the radial displacement of side plate and the pump housing, ensure that the sealability of side plate and the pump housing.
Its technological scheme is such: a kind of lateral plate structure, it comprises side plate plate body, described side plate plate body is provided with gear shaft holes, and corresponding described gear shaft holes side is provided with seal groove, it is characterized in that: described side plate plate body is at least provided with two positioning convex.
It is further characterized in that: described side plate plate body is 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 said structure of the present utility model, owing to side plate plate body being at least provided with two positioning convex, 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, ensure that the sealability of side plate and the pump housing.
Accompanying drawing explanation
Fig. 1 is the utility model side plate plan view;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
See Fig. 1, Fig. 2, a kind of lateral plate structure, it comprises 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 gear shaft holes 2-1,2-2 outer end and side between 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, ensure that the sealability of side plate and the pump housing.
In the present embodiment; positioning convex 3 is separately positioned on gear shaft holes 2-1,2-2 outer end and side between gear shaft holes 2-1,2-2; certain positioning convex also can be arranged on other positions; as long as arrange at least two positioning convex; when achieving side plate installation; achieving the radial location of side plate and the pump housing, is all the scope of the utility model protection.
