Abstract
The invention relates to a gear oil pump. The gear oil pump comprises an oil pump shell (1), a driving gear (2) and driven gears (3). The driving gear (2) and the driven gears (3) are meshed in a one-by-one mode to form a meshing transmission chain, and the meshing transmission chain is arranged in the sealed oil pump shell (1). An oil hole (4) is formed in the position, located at the tangent position where each pair of gears are meshed, on the oil pump shell (1); the outer profile of a transmission gear pair is matched with an inner cavity of the oil pump shell; the number of the driving gear (2) is one; the number of the driven gear (3) is more than two. In the working process, when inadequate oil absorption happens to one path, the oil absorption effect of other oil paths is not affected, and meanwhile the gear utilization rate is improved. The number of parts is effectively decreased, the weight and the occupied space of the parts are effectively reduced, and the reliability of the oil pump is improved.
Description
Technical field
The present invention relates to a kind of oil pump structure, especially a kind of gear oil pump.
Background technique
In many mechanical devices, the use of oil pump is comparatively general.The lubricating oil that cannot be back to main oil sump by Action of Gravity Field everywhere in device can be drawn back main oil sump by oil pump, or oil is transmitted to the high region of pressure from the region that pressure is low, thus realizes the Efficient Cycle of oil system.Traditional gear lubricating oil pump structure is shown in Fig. 1, is single channel gear oil pump, can only realize the pump oil effect of single channel.When some needs to provide multichannel pump oil oil circuit, be generally configure a single channel gear oil pump at every Lu Shangjun, multiple gear oil pump therefore can be needed to realize respectively, thus cause number of spare parts to increase, weight increases, and reliability reduces.
Summary of the invention
The object of this invention is to provide a kind of gear oil pump, Multi-oil circuit pump oil can be realized, there is the feature that number of spare parts is few, lightweight, reliability is high simultaneously.
Concrete technological scheme of the present invention is: gear oil pump comprises oil pump case, driving gear, driven gear, described driving gear drives driven gear to engage one by one and forms engagement driving chain and be arranged in closed oil pump case, the tangent position that oil pump case is positioned at often pair of gears meshing is provided with oilhole, the external frame of driving gear pair coordinates with the inner chamber of oil pump case, described driving gear is one, the quantity of driven gear is greater than two, and driving gear is positioned at the arbitrary position of whole engagement driving chain.The position that oil pump case is positioned at oilhole is processed with oil storage tank.
The present invention is the oil pump designing a kind of new configuration on traditional oils pump structure basis, is undertaken integrated by multiple single pump, realizes Multi-oil circuit pump oil.Two-way pump oil can be realized by 3 gears, save 1 driving gear than 2 single pumps, No. three pump oil can be realized by 4 gears, save 2 driving gears than 3 single pumps.The present invention at work, when wherein a road oil suction is insufficient, does not affect the oil absorbing effect of other oil circuits, promotes gear utilization ratio simultaneously, effectively reduces number of spare parts, weight and taken up space, and improves the reliability of oil pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional gears oil pump;
Fig. 2 is the two-way gear oil pump structural representation of invention;
Fig. 3 is No. three gear oil pump structural representations of invention.
Embodiment
As shown in the figure, described gear oil pump comprises oil pump case 1, driving gear 2, driven gear 3, described driving gear 2 and driven gear 3 engage one by one and form engagement driving chain and be arranged in closed oil pump case 1, the tangent position that oil pump case 1 is positioned at often pair of gears meshing is provided with oilhole 4, the external frame of driving gear pair coordinates with the inner chamber of oil pump case, described driving gear 2 is one, and the quantity of driven gear 3 is greater than two.Described driving gear 2 is positioned at the arbitrary position of whole engagement driving chain.The position that described oil pump case 1 is positioned at oilhole 4 is processed with oil storage tank 5.
Claims (3)
