Abstract
The present invention discloses a double-channel hydraulic pump, which comprises a front cover, a front pump body, a rear pump body and a rear cover, wherein the front pump body is arranged on the front pump body through a hexagon cylindrical bolt, a front pump drive gear and a front pump driven gear are arranged inside the front pump body, the shaft body of the front pump drive gear penetrates through the front cover, an elastic blocking ring for the shaft sleeves on the front end of the front pump drive gear, a bearing sleeves inside the front pump body, and the matching position of the front cover and the front pump drive gear is provided with an elastic blocking ring for the hole and a skeleton oil seal. According to the present invention, the double-channel hydraulic pump has characteristics of simple structure and easy use; and with the double-channel hydraulic pump, the problems of insufficient oil pump oil supply and serious gear wear in the prior art are solved, and the working efficiency can be effectively improved.
Description
Technical field:
The present invention relates to pump field, particularly relate to a kind of Twin channel oil hydraulic pump.
Background technique:
Gear pump nibbles rotation mutually with two gears to carry out work.General pressure gear oil pumping forces is at below 6MPa, and flow is larger.Gear oil pump is equipped with a pair swiveling gear in the pump housing, an active, and one passive, relies on engaging each other of two gears, divides two independently parts the whole active chamber in pump.A is suction chamber, and B is discharge side.When gear enters engagement, liquid is extruded, and forms highly pressurised liquid and outside pump discharge excavationg pump.In some oil hydraulic pumps working life the short efficiency causing whole machinery, therefore need design a kind of Twin channel oil hydraulic pump.
Summary of the invention:
Object of the present invention is just to provide a kind of Twin channel oil hydraulic pump, solves the problem that prior art oil pump feed is not enough and gear wear is serious.
The technical solution used in the present invention is:
A kind of Twin channel oil hydraulic pump, include protecgulum, the front pump housing, the rear pump housing, bonnet, the described front pump housing is arranged on the front pump housing by interior hexagonal cylindrical bolt, a front pump driving gear and front pump driven gear is provided with in the described front pump housing, the axis body of described front pump housing driving gear passes protecgulum and is sheathed with circlip for shaft in the front end of front pump driving gear, described front pump housing inner sleeve is closed bearing, and the described cooperation place at protecgulum and front pump driving gear is provided with circlip for hole and outside framework oil seal; The described rear pump housing is provided with bonnet by hollow locating stud, is provided with rear pump driven gear and rear pump driving gear in the described rear pump housing; Be provided with rear pump connecting plate in described rear pump housing body, described front pump driving gear and rear pump driven gear two ends are provided with connecting plate, and described connecting plate is provided with spline housing, and described spline housing two ends are provided with circlip for shaft.
Compared with prior art, beneficial effect of the present invention is:
Structure of the present invention is simple, easy to use, solves the problem that prior art oil pump feed is not enough and gear wear is serious, can effectively increase work efficiency.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail:
A kind of Twin channel oil hydraulic pump, include protecgulum 1, the front pump housing 5, the rear pump housing 16, bonnet 17, the described front pump housing 1 is arranged on the front pump housing 5 by interior hexagonal cylindrical bolt 4, a front pump driving gear 6 and front pump driven gear 7 is provided with in the described front pump housing 5, the axis body of described front pump housing driving gear 6 passes protecgulum 1 and is sheathed with circlip for shaft 18 in the front end of front pump driving gear 6, be sheathed with bearing 8 in the described front pump housing 5, the described cooperation place at protecgulum 1 and front pump driving gear 6 is provided with circlip for hole 2 and outside framework oil seal 3; The described rear pump housing 16 is provided with bonnet 17 by hollow locating stud 9, is provided with rear pump driven gear 14 and rear pump driving gear 15 in the described rear pump housing 16; Be provided with rear pump connecting plate 13 in the described rear pump housing 16 body, described front pump driving gear 6 and rear pump driven gear 14 two ends are provided with connecting plate 10, and described connecting plate 10 is provided with spline housing 11, and described spline housing 11 two ends are provided with circlip for shaft 12.
