Abstract
The invention provides a gear oil pump with double transmission gear shafts. The gear oil pump comprises a pump body. The pump body is composed of a left end cover, a right end cover, a cylindrical pin, a fixing bolt, the first transmission gear shaft, the second transmission gear shaft, a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear and a shaft sealing device. The upper end of the left end cover is fixedly connected with the upper end of the right end cover through the cylindrical pin, and the lower end of the left end cover is fixedly connected with the lower end of the right end cover through the fixing bolt. The first transmission gear shaft is installed at the upper end of the interior of the left end cover and the upper end of the interior of the right end cover, and the second transmission gear shaft is installed at the lower end of the interior of the left end cover and the lower end of the interior of the right end cover. According to the gear oil pump with the double transmission gear shafts, one-way or two-way oil pump oil pumping can be achieved, and the double transmission gear shafts are arranged, so that when emergency faults happen to one of the transmission gear shafts and one end of a coupler, direction turning is convenient, and the other transmission gear shaft can be used to drive the gear oil pump to operate; and the gear oil pump is high in oil pumping efficiency and low in using effect.

Described first driving gearshaft passes right end cap, described first driving gearshaft and right end cap seam assembly axis sealing device；Described second driving gearshaft passes left end cap, described second driving gearshaft and left end cap seam assembly axis sealing device.
Described shaft sealer is made up of firm banking, fixed cover, sealing ring, airtight and watertight padding, described firm banking is by fixing nut apparatus on left end cap or right end cap, described fixed cover is welded on firm banking, described gasket set is inside fixed cover, being through on the first driving gearshaft or the second driving gearshaft, described sealing packing device is inside sealing ring.
The outer end of described first driving gearshaft and the second driving gearshaft is one shaft coupling of device all, connects driving device by shaft coupling.
Beneficial effects of the present invention: it is an object of the invention to provide a kind of gear oil pump with double; two driving gearshaft, single channel or two-way oil pump pump oil can be realized, and there is double; two driving gearshaft, when there is emergency with shaft coupling one end in a driving gearshaft, it is easy to turn direction, using another driving gearshaft, the operating of driven gear oil pump is, and its pump oil efficiency is high, use cost is relatively low.
A kind of gear oil pump with double; two driving gearshaft of the present invention, at the first driving gearshaft and right end cap, all assembly axis sealing device between the second driving gearshaft and left end cap, reduce power transmission shaft rocking when rotated, improve the stability of equipment work, when making to rotate, entirety smoothes out more, and friction each other also reduces.
