Abstract
The utility model discloses a connection structure between a front pump and a rear pump on a gear oil pump. The connection structure comprises a front pump driving gear and a rear pump driven gear, wherein an oil seal is mounted between a gear shaft of the front pump driving gear and a gear shaft of the rear pump driven gear; a positioning sleeve is arranged between the gear shaft of the front pump driving gear and the rear pump driven gear; the oil seal is sleeved with the positioning sleeve; a cross joint is mounted in the positioning sleeve; the cross joint connects the front pump driving gear and the rear pump driven gear together and locks the oil seal closely; a front connection plate is mounted on the gear shaft of the front pump driving gear; a rear connection plate is mounted on the rear pump driven gear; and the front connection plate and the rear connection plate are fixedly connected through bolts. The connection structure is simple; the front oil pump and the rear oil pump are isolated through the oil seal, so that the front oil pump and the rear oil pump can adopt different media of hydraulic oil; and installation and fastening are convenient.
Description
Technical field
The utility model relates to oil pump, is mainly the linkage structure between forward and backward pump on a kind of gear oil pump.
background technique
Existing gear oil pump is gone forward, do not adopt oil sealing to separate between gear pump, and during use, what in forward and backward oil pump, use is the hydraulic oil of same medium, and can not adopt the hydraulic oil of different medium, uses under special circumstances inconvenient.
Model utility content
Technical problem to be solved in the utility model is to provide the linkage structure between forward and backward pump on a kind of gear oil pump, it is simple in structure, between forward and backward oil pump, adopt oil sealing isolation, make can adopt in forward and backward oil pump the hydraulic oil of different medium, and fastening convenience is installed.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Linkage structure on a kind of gear oil pump between forward and backward pump, include front pump driving gear and rear pump driving gear, it is characterized in that: between the gear shaft of described front pump driving gear and the gear shaft of rear pump driving gear, oil sealing is installed, between the gear shaft of described front pump driving gear and the gear shaft of rear pump driving gear, be provided with a setting sleeve, setting sleeve is enclosed within outside oil sealing, in described setting sleeve, cross shaped joint is installed, cross shaped joint links together the gear shaft of front pump driving gear and rear pump driving gear and oil sealing is locked; Front connecting plate is installed on the gear shaft of described front pump driving gear, rear connecting plate is installed on the gear shaft of rear pump driving gear, front connecting plate and rear connecting plate are bolted to connection.
On the gear shaft of described front pump driving gear and the gear shaft of rear pump driving gear, axle sleeve is installed, described forward and backward connecting plate is arranged on the gear shaft of front pump driving gear and rear pump driving gear by axle sleeve.
The utility model has the advantages that:
The utility model is simple in structure, adopts oil sealing isolation between forward and backward oil pump, makes can adopt in forward and backward oil pump the hydraulic oil of different medium, and fastening convenience is installed.
