Abstract
The invention provides a high-pressure gear pump with a rectangular oil inlet and relates to hydraulic machinery. The oil inlet is a rectangular slot hole; the length of the slot hole is equal to or slightly smaller than that of a tooth; and under the condition of guaranteeing that the flow speed of the oil inlet is not changed, the width of the oil inlet is reduced to the maximum extent, an inhalation angle phi' is reduced, the axial stress of a gear is reduced, the service life of a bearing is prolonged, the no-failure operation time of the high-pressure gear pump is increased, maintenance cost is reduced, and economic benefit is increased. The high-pressure gear pump is easy and convenient to manufacture and is favorable for popularization and using.
Description
Technical field
The present invention relates to a kind of hydraulic machinery, especially a kind of high-pressure gear pump with rectangle filler opening.
Background technique
Constructional engineering machinery, handling machinery etc. require supporting high-pressure gear pump, require rated pressure will reach 23MPa, and actual working pressure surpasses 25MPa.The filler opening of high-pressure gear pump is a circular port at present, and it is bigger that it sucks the angle, so the radial force that gear shaft is subjected to is just big, and the radial force that bearing bears is big, and working life is short.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of high-pressure gear pump with rectangle filler opening, filler opening is made into the rectangle slotted hole, the length of slotted hole and the equal in length of tooth.
The present invention is achieved through the following technical solutions: a kind of high-pressure gear pump with rectangle filler opening, this gear pump adopts the two-piece type structure, be the inner chamber that driving gear, driven gear, two floating side plates and two W type seal rings are installed in the pump housing, the pump housing and pump cover connect to form simply connected or two or multi-gear pump by bolt and locating stud; The gear shaft of described driving gear and driven gear is installed on the pump housing and the pump cover by sliding bearing respectively; Described driving gear is connected with power source by joining shaft, joining shaft by Bearing Installation on pump cover; Filler opening and oil outlet are arranged on the pump housing; It is characterized in that: described filler opening is the rectangle slotted hole.The length of rectangle slotted hole is equal to or slightly less than the length of the driving gear and the driven tooth gear teeth.
Good effect of the present invention is:
1, filler opening is the rectangle slotted hole, and the minimum that its width is done alleviates the radial force that gear shaft is subjected to, and prolongs the working life of bearing, increases the time between failures of high-pressure gear pump, reduces maintenance cost, increases economic efficiency.
2, making is simple, convenient, is convenient to promote the use of.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A--A sectional drawing of Fig. 1.
Fig. 3 is the B--B sectional drawing of Fig. 2.
Among the figure: 1, joining shaft, 2, bearing, 3, pump cover, 4, the pump housing, 5, driving gear, 6, driven gear, 7, bolt, 8, sliding bearing, 9, floating side plate, 10, W type seal ring, 11, filler opening, 12, oil outlet.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3: a kind of high-pressure gear pump with rectangle filler opening, this gear pump adopts the two-piece type structure, be the inner chamber that driving gear 5, driven gear 6, two floating side plates 9 and two W type seal rings 10 are installed in the pump housing 4, the pump housing 4 and pump cover 3 connect by bolt 7 and locating stud and form simply connected or two or multi-gear pump; The gear shaft of described driving gear 5 and driven gear 6 is installed on the pump housing 4 and the pump cover 3 by sliding bearing 8 respectively; Described driving gear 5 is connected with power source by joining shaft 1, and joining shaft 1 is installed on the pump cover 3 by bearing 2; Filler opening 11 and oil outlet 12 are arranged on the pump housing 4; It is characterized in that: described filler opening 11 and oil outlet 12 are the rectangle slotted hole.
The length of described filler opening 11 and oil outlet 12 rectangle slotted holes is equal to or slightly less than the length of driving gear 5 and driven gear 6 teeth.
Filler opening 11 adopts the rectangle slotted holes, and according to the gear pump working principle, the formula of the radial force Fpy that produces along the circumference of gear hydraulic coupling is:
Filler opening is the rectangle slotted hole, guaranteeing to dwindle the width of filler opening to greatest extent under the constant situation of filler opening flow velocity, reduces to suck the angle
Alleviate the radial force that gear shaft is subjected to, prolong the working life of bearing, increase the time between failures of high-pressure gear pump, reduce maintenance cost, increase economic efficiency.Make simply, conveniently, be convenient to arrange wide use.
