Abstract
The utility model discloses a two section type thin shaft sleeve hydraulic gear pump. The hydraulic gear pump (1) is changed into two-segment type from three-segment part, i.e. a rectangular flange front cover (2) and a pump body (3) are changed into a whole, and a back cover (4) is connected with the pump body (3) through nuts, wherein, a shaft sleeve (5) is in a trenched or side-reducing trenched structure, i.e. the high pressure side of the radial section of the shaft sleeve (5) is provided with a groove (6). On the premise of keeping the functions and the manufacturability changeless, the utility model can decrease about 30 percent of material consumption, reduces the quantity of parts and simplifies manufacturing procedure, which is considerable in economic benefit.
Description
Technical field
The utility model relates to hydraulic gear pump in the hydraulic element, is specifically related to the thin axle sleeve mekydro pump structure of two-part.
Background technique
At present, production in enormous quantities with the supporting discharge capacity scope in market be that the agricultural hydraulic gear pump of mesohigh of 6-14ml/r specification is commonly the 3 stops assembling, its integral thickness is 1.22 times of the gear diameter of axle, the materials consumption height, number of spare parts is many, and manufacturing procedure is numerous, the existing profitless space of the market price.
Technology contents
The purpose of this utility model is: design the thin axle sleeve hydraulic gear pump of a kind of two-part, keeping reducing design cost by structural design under product usability and the supporting adoptive prerequisite in market, increase economic efficiency.
The purpose of this utility model is achieved in that and changes the 3 stops hydraulic gear pump into two-part, and promptly the square type flange protecgulum and the pump housing become one, and its axle sleeve is grooving or subtracts the thin axle sleeve of limit grooving that promptly axle sleeve radially is designed to grooved in the section high pressure side.
Description of drawings
Fig. 1 is the utility model pump structure schematic representation
Fig. 2 is the utility model axle sleeve structure schematic representation
Among the figure: 1 hydraulic gear pump, 2 flange protecgulums, 3 pump housings, 4 bonnets, 5 axle sleeves, 6 grooves.
Specific implementation method
Below in conjunction with accompanying drawing the utility model is described in further detail.As shown in Figure 1, this hydraulic gear pump 1 changes two-part into by 3 stops, and promptly square type flange protecgulum 2 becomes one with the pump housing 3, and bonnet 4 connects on the pump housing 3 through nut, its Intermediate shaft sleeve 5 is for grooving or subtract limit grooving structure as shown in Figure 2, i.e. the radially section high pressure side fluted 6 of axle sleeve 5.
During work, discharge capacity 6ml/r pump adopts the 12-13mm axle sleeve, and the 14ml/r displacement pump adopts the 18mm axle sleeve, and be that 33mm or 32mm, 31.4mm gear pump are optimized the flute profile design to centre distance, reduce the facewidth and bearing specific pressure, add large-diameter, improve gear rigidity and reduce specific pressure.
The utility model adopts this improvement structure, can reduce materials consumption about 30%, and the material-saving effect is fairly obvious, and economic benefit is considerable, and every after tested performance index all meet standard.
Claims (2)
1, the thin axle sleeve hydraulic gear pump of two-part, it is characterized in that: this hydraulic gear pump (1) changes two-part into by 3 stops, and promptly square type flange protecgulum (2) becomes one with the pump housing (3), and bonnet (4) connects on the pump housing (3) through nut.
2, the thin axle sleeve hydraulic gear pump of two-part according to claim 1 is characterized in that: axle sleeve wherein (5) is for grooving or subtract limit grooving structure, promptly in the radially section high pressure side fluted (6) of axle sleeve (5).
