Abstract
The utility model discloses a gear pump equipped with asymmetric side plates. The gear pump comprises a pump body and a front cover, wherein the pump body comprises a driving gear and a driven gear; a thin side plate and a thick side plate are arranged at the joint of the pump body and the driving gear; the thin side plate is positioned on the side near to the front cover; the thick side plate is positioned inside the pump body and on the side away from the front cover; a sealing groove is formed in the joint of the front cover and the thin side plate; another sealing groove is formed in the thick side plate. According to the gear pump provided by the utility model, as the design of one thick side plate and one thin side plate is adopted, the production cost of the side plates is reduced, the whole gear pump is simpler in structure and lighter in weight, and the economic benefit of the gear pump is promoted.
Description
Technical field
The utility model relates to a kind of pump housing, relates in particular to a kind of gear pump that is equipped with asymmetric side plate.
Background technique
Two at present domestic body gear pump side-planks generally adopt two groups of totally four side plates, be two of the every sides of each gear, reason is on the two body pump pump housings, to process seal groove not too easily to realize, so seal groove has been placed on side plate, use two thick side plates more abroad, on two thick side plates, be all processed with seal groove.But, be no matter to adopt two groups of totally four side plates or adopt two thick side plates, the cost cost higher, that cause the whole pump housing of side plate rises, in addition, adopts two groups the design of totally four side plates make the slightly aobvious complexity of structure of the whole pump housing.
Chinese patent notice of authorization CN202707481U, notice of authorization day is that the utility model patent of on 01 30th, 2013 discloses the folded formula side plate of a kind of gear pump, described side plate is made up of front side plate group and back side panel group, described front side plate group is made up of epipleural and lower side panel, and described back side panel group is made up of epipleural and lower side panel.The every overlapping type side plate of this model utility is made up of upper and lower two side plates stack, has groove and the projection of circular arc between two side plates, forms combination seal, thereby realizes axial seal and the hydraulic floating compensation of gear pump, reduces the radial force of gear pump.This design has adopted four side plates of two groups of side plate group works, structure slightly complicated, and cost of production is high.
Summary of the invention
The purpose of this utility model is to overcome existing technology middle gear pump side plate structure complexity, problem that cost of production is high, and a kind of simple in structure, easy to use, gear pump that is equipped with asymmetric side plate that economic benefit is high is provided.
For realizing above object, technical solution of the present utility model is: a kind of gear pump that is equipped with asymmetric side plate, comprise the pump housing and protecgulum, in the described pump housing, include driving gear and driven gear, the junction of the described pump housing and driving gear is provided with thin side plate and thick side plate, and wherein thin side plate is positioned near protecgulum one side, and thick side plate is positioned at pump body away from protecgulum one side, on protecgulum, be provided with seal groove with thin side plate junction, on thick side plate, be provided with seal groove.
Described seal groove is numeral " 3 " type.
The thickness of described thin side plate is between 2.0-3.0 millimeter.
The thickness of described thick side plate is between 5.0-7.0 millimeter.
Junction between described driven gear and the pump housing is also provided with thin side plate and thick side plate.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has used the setting of thin side plate and thick side plate, on the protecgulum being connected with thin side plate, can process seal groove, on thick side plate, be directly processed with seal groove, an one thick thin design reduces the cost of production of side plate, and whole gear pump structure also becomes simply, weight lightens, economic benefit gets a promotion.
