Abstract
The utility model discloses a front end shield oil seal structure of a duplicate gear oil pump. A connection plate in the prior art is changed to two connection plates; a first connection plate, namely a left side plate, serves as a rear cover of a front pump body, a countersink is reamed in a position where a bolt is arranged on the inner side of the connection plate, a front end cover of a front pump and the front pump body are connected in series by the bolt, a bolt head is hidden into the countersink, and then a right side plate and the left side plate are connected and fixed by a peripheral bolt; and then a rear pump body, a rear end cover and other parts are connected in series by a bolt, therefore, the bolt on a rear pump extends into the right side plate of the connection plate. The front end shield oil seal structure has the benefits as follows: through the mechanical design that the two connection plates are connected in series with the front pump and the rear pump respectively, the problem that an original front cover cannot seal oil is solved, customers' requirements under different working conditions can be met, and the structure is simple.
Description
Technical field
The utility model relates to the gear oil pump field, and concrete is a kind of duplicate gear oil pump front cover oil sealing structure.
Background technique
At present; The series connection of known CBQTYB duplicate gear oil pump be through in the past, rear end cover respectively on a thicker connecting plate of centre drivescrew connect; Because screw is to squeeze into from front cover; So just cause the screw hexagon head to be exposed on the protecgulum positioning boss face outward, make that positioning boss cylindrical oil sealing structure is destroyed.
The model utility content
The utility model is in order to solve CBQTYB duplicate gear oil pump front cover positioning boss and not broken by screw head and play the oil sealing problem; The utility model provides a kind of screw is driven into the front cover connection structure connecting from connecting plate; This structure can not only be protected the integrity of front cover positioning boss cylindrical; Play the oil sealing effect, also avoided the problem that interferes with each other between the screw head simultaneously cleverly.
The technological scheme of the utility model:
Duplicate gear oil pump front cover oil sealing structure; Comprise the forward and backward pump housing; Be fixedly connected with forward and backward end cap on the forward and backward pump housing respectively, it is characterized in that: between the described forward and backward pump housing through the connecting plate fixed seal connection, described connecting plate comprise be fixed together about two blocks of side plates; Have cavity between two blocks of side plates; Fixed seal connection between two blocks of side plates wherein runs through the fixing described preceding pump housing, front cover through stay bolt on the left sideboard of connecting plate, passes the described back pump housing through stay bolt on the described rear end cover and is fixedly connected on the right sideboard of said connecting plate; All be rotatablely equipped with master and slave moving axis in the described forward and backward pump housing, all connect between the master and slave moving axis through gear transmission; Driving shaft before described in the pump housing passes described front cover and gets in the described connecting plate, and in described connecting plate, is in transmission connection through the driving shaft in the connecting sleeve and the described back pump housing, and described connecting sleeve is positioned at the cavity of described connecting plate; Be provided with cavity in the described front cover, described driving shaft is with Sealing outward, and the sealing part is installed in the cavity in the described front cover.
Described embedded gear oil pump connecting sleeve is characterized in that: in the described forward and backward pump housing some support sleeves are installed, described master and slave moving axis is mounted thereon; All be sealedly and fixedly connected between the described forward and backward end cap and the described forward and backward pump housing.
Earlier with first connecting plate left sideboard as the bonnet of the preceding pump housing (profile is bigger, and be with one outside enclose screw hole), the position that screw arranged in the connecting plate inboard is ream one counterbore all; With the front cover of screw with front pump, the preceding pump housing is together in series, and screw head is hidden in the counterbore; Be connected fixing with left sideboard with peripheral screw with right sideboard then; To the back pump housing with screw again, parts such as rear end cover are together in series, and make the screw of back pump be driven on the connecting plate right sideboard like this.Like this, reach the integrity of protection front cover positioning boss cylindrical, reached the purpose of the Machine Design that the pump screw is interfered before and after solving simultaneously again.
The advantage of the utility model:
The beneficial effect of the utility model is, the Machine Design of pump before and after connecting respectively through two connecting plates of this usefulness has solved the problem that original protecgulum can not oil sealing, has satisfied the client to the requirement under the different operating situation, and is simple in structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; Duplicate gear oil pump front cover oil sealing structure comprises the forward and backward pump housing 1,2, is fixedly connected with forward and backward end cap 3,4 on the forward and backward pump housing 1,2 respectively; The described forward and backward pump housing 1, between 2 through connecting plate 5 fixed seal connections; Described connecting plate 5 comprise be fixed together about two blocks of side plates, have cavity between two blocks of side plates, fixed seal connection between two blocks of side plates; Wherein run through the fixing described preceding pump housing 1, front cover 3 through stay bolt 11 on the left sideboard of connecting plate 5, pass the described back pump housing 2 through stay bolt 11 on the described rear end cover 4 and be fixedly connected on the right sideboard of said connecting plate 5; All be rotatablely equipped with master and slave moving axis in the described forward and backward pump housing 1,2, all connect between the master and slave moving axis, be provided with cavity in the described connecting plate 5 through gear transmission; Driving shaft 6 before described in the pump housing 1 passes described front cover 3 and gets in the described connecting plate 5; And in described connecting plate 5, be in transmission connection through the driving shaft 6 in the connecting sleeve 7 and the described back pump housing 2, described connecting sleeve 7 is positioned at the cavity of described connecting plate 5; Be provided with cavity in the described front cover 3, the described driving shaft 6 outer Sealings 9 that are with, sealing part 9 is installed in the cavity in the described front cover 3, in the forward and backward pump housing 1,2 some support sleeves 10 is installed, and described master and slave moving axis is mounted thereon; The described forward and backward end cap 3,4 and the described forward and backward pump housing 1, all be sealedly and fixedly connected between 2.
