Abstract
The utility model belongs to a hydraulic element, and particularly relates to a side plate of a high-pressure gear pump. The side plate comprises a side plate body. A chamfer angle is formed between the upper side face of the side plate body of the shape like an Arabic number '8' and the end face adjacent to the upper side face, wherein the chamfer angle is 2 * 45 degrees. According to the side plate of the high-pressure gear pump, due to the fact that the structure of the side plate is changed, after chamfering, the high-pressure gear pump is chamfered under a high-pressure working state, the radial force balance effect is achieved, the applied internal pressure and the applied external pressure of the side plate are basically balanced, and volumetric efficiency of the high-pressure gear pump is improved.
Description
Technical field
The utility model belongs to hydraulic element, particularly a kind of side plate of high pressure gear pump.
Background technique
The side plate of high-pressure gear pump is the critical component of high-pressure gear pump, whether the structure of side plate rationally directly affects the quality and performance of whole element, original side plate of high pressure gear pump design is without chamfering, unreasonable structure, cause high-pressure gear pump pressure imbalance at work, its volumetric efficiency is low, can not guarantee usage requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, can enlarging volume efficiency, guarantee the side plate of high pressure gear pump of working pressure balance.
The technological scheme that the utility model technical solution problem adopts is: side plate of high pressure gear pump comprises side plate body, be characterized in being provided with chamfering between the side plate body upper side of 8-shaped and an adjacent end face, and chamfering is 2 * 45
0.
The beneficial effects of the utility model are: side plate of high pressure gear pump is owing to having changed lateral plate structure, after chamfering, high-pressure gear pump chamfering under high-pressure work state plays the effect of balanced radial force, side plate external and internal pressure is stressed in a basic balance, has improved the volumetric efficiency of high-pressure gear pump.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is the structural drawing of side plate of high pressure gear pump one side.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
In figure, 1-side plate body; 1-1-chamfering; 1-2-oil groove; 1-3-gear shaft shoulder hole; 1-4-seal groove.
Embodiment
Embodiment, with reference to accompanying drawing 1 ~ 3, is provided with chamfering 1-1 between side plate body 1 upper side of the 8-shaped of side plate of high pressure gear pump and an adjacent end face, and chamfering 1-1 is 2 * 45
0, being provided with on the end face of chamfering 1-1 and being respectively equipped with oil groove 1-2 and gear shaft shoulder hole 1-3, the end face corresponding with the end face that is provided with chamfering 1-1 is provided with seal groove 1-4.
The using method of side plate of high pressure gear pump is: two side plate bodies 1 are placed in respectively high pressure gear pump body inner chamber, side plate body 1 is relative with the end face of driven gear with the driving gear of high-pressure gear pump respectively with the end face of chamfering 1-1, and is sleeved on driving gear shaft and driven gear shaft.
