Abstract
The utility model relates to a pump body of a gear pump, and belongs to the hydraulic transmission technology. The pump body is characterized in that a gear room and one side end cover are integrally arranged; and the gear room, a bearing hole, an E-shaped elastic ring groove, an oil inlet (an oil outlet), a screw hole and a location pinhole are arranged in the pump body. The pump body of the gear pump has the advantages of simple structure, high machining precision, simplified production technology, easiness in massive production and reduced production cost.
Description
Technical field: the utility model relates to a kind of pump housing of gear pump, belongs to hydraulic transmission technology field.
Background technique: traditional pump housing is made up of forward and backward end cap, housing three parts, processing respectively, and desired strength is high, wear resistance is good, machining accuracy is high; Because the restriction of process equipment, the position degree does not reach requirement sometimes, is difficult for installing; Seal is poor, and processing technology is complicated, and efficient is low; Reject rate is high, in its process of manufacture, also will waste a large amount of noble metals.
Summary of the invention: the purpose of the utility model is to provide a kind of simple in structure, is easy to production and processing, and a gear chamber and an end cap are made as one, has only an end cap, can significantly improve the high-intensity gear pump pump housing of pump housing quality of fit.
The utility model is achieved in that this pump housing is made as one with a gear chamber and a side end cap, is provided with gear chamber, bearing hole, E type elasticity ring recess and screw, positioning pin hole in the pump housing.Gear chamber can be made as one with front cover, also can be made as one with rear end cover.
The advantage of the utility model is:
1, simplified processing process is saved noble metal, energy efficient, and manufacturing efficiency is high, is easy to produce in enormous quantities.
2, precision is high, and efficient is high, and the life-span is long.
3, greatly reduce reject rate.
Description of drawings: the utility model is further specified below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of the utility model.
Embodiment: this device is made as one with a gear chamber and a side end cap, is provided with gear chamber 3, bearing hole 4, E type elasticity ring recess 6, filler opening (oil outlet) and screw 5, positioning pin hole 2 in the pump housing 1.Gear chamber can be made as one with front cover, also can be made as one with rear end cover.
This device unites two into one the pump cover and the pump housing of traditional gear pump, makes it have all functions of the pump cover and the pump housing.
The utility model is simple in structure, and machining accuracy is high, simplifies production technology, is easy to produce in enormous quantities, reduces production costs.
