Description
Technical field:
The utility model relates to a kind of gear oil pump, particularly a kind of gear oil pump that is applicable to vehicle automatic mechanical speed variator control usefulness.
Background technique:
At present, existing gear pump is generally formed by major parts such as gear, major and minor axis, the pump housing, front and rear covers, spline, needle bearing, oil sealings.The front and rear covers and the pump housing have formed the oil pocket of sealing.The driving and driven gear meshing that connects by spline is rotated and is realized oil suction and press oil.By preventing oil sealing and cooperating of major and minor axis the leakage of oil.The gear pump of this kind structure, because its gear bears unbalanced radial hydraulic pressure, so bearing wear is serious, the raising of working pressure is restricted, flow pulsation is big, causes the system pressure pulsation big, the noise height; And its radial and axial size is all very big, and part is more again, thereby, can not satisfy occasion little to spatial requirement, that the pressure requirement is higher again.
Summary of the invention:
Technical problem to be solved in the utility model is: a kind of deficiency that is intended to overcome above-mentioned prior art is provided, can satisfies gear oil pump little to spatial requirement, that the pressure requirement is higher again, suction capacity is strong.The technological scheme of its solution is: the both sides, plane of intermeshing driving and driven gear combine with a side plane of the bearing of two figures of eight that support driving and driven gear shaft simultaneously respectively in the pump housing inner chamber, the waist of approximate " V " shape of figure of eight bearing outside surface and the curved surface of driving and driven gear match with the surface of pump housing inner chamber, form oil sucting cavity and pumping cavity respectively; Backstop cover be respectively equipped with communicate with oil sucting cavity and pumping cavity into and out of oilhole; Between the outer side plane of the figure of eight bearing in the pump housing and the pump housing and the forward and backward door respectively by oil sealing sealing.
Described driving gear shaft and driving gear, driven gear shaft and driven gear are integral structure.
The bearing of the described figure of eight is provided with the oil groove that links to each other with oil sucting cavity with axis hole with a side plane of the plane side combination of driving and driven gear.
The shape approximation of described oil sealing " heart " shape or " apple " shape.
Be respectively equipped with the projection and the limiting stopper that match with approximate " heart " shape or " apple " shape oil sealing on the inner side surface of described forward and backward door.
Compare with existing gear oil pump, its technique effect is: oil pump of the present utility model has been simplified the Placement of gear and transmission shaft, has cancelled gear and has been connected with spline between the axle, with gear with spool be made into one, has simplified the gear radial dimension; Simultaneously, adopt two figure of eight bearings to replace traditional needle bearing, on the one hand by realizing " 8 " word bearing inner surface and cooperating of driving and driven gear shaft the axle support effect of gear, cooperate with pump housing internal surface by figure of eight bearing outside surface on the other hand, to pass in and out oil duct junction separately, realize the isolation of oil sucting cavity and pumping cavity; In addition, because the turnover oil duct is separated by figure of eight bearing, so adopt " heart " shape or " apple " shape oil sealing to be embedded into to realize in the cavity of good preceding door that cooperates with " heart " shape or " apple " shape oil sealing of prior casting and back door and the sealing of the pump housing, thereby better will pass in and out the oil duct isolation.Therefore, oil pump of the present utility model have simple in structure, size is little, in light weight, make easy to maintenance, cheap, reliable operation, suction capacity pressure height, noise strong, that produce low, to plurality of advantages such as oil pollution are insensitive.

Embodiment:
As shown in Figure 1, the both sides, plane of intermeshing driving and driven gear 8,9 combine with two side planes that support the figure of eight bearing 4 of driving and driven gear shaft 5,7 simultaneously respectively in the pump housing 1 inner chamber.Driving gear shaft and driving gear, driven gear shaft and driven gear are integral structure.The waist of approximate " V " shape of figure of eight bearing outside surface and the curved surface of driving and driven gear match with the surface of pump housing inner chamber, form oil sucting cavity 10 and pumping cavity 11 (see figure 2)s respectively.Be respectively equipped with on the back door 3 communicate with oil sucting cavity and pumping cavity into and out of oilhole 31,32 (see figure 5)s.Seal by oil sealing 2 respectively between the outer side plane of the figure of eight bearing in the pump housing and the pump housing and the forward and backward door.The shape approximation of oil sealing " heart " shape or " apple " shape (see figure 4).Be respectively equipped with the projection 35 and limiting stopper 34 (see figure 5)s that match with approximate " heart " shape or " apple " shape oil sealing on the inner side surface of forward and backward door 6,3, so that be similar to being inserted in and locating of " heart " shape or " apple " shape oil sealing.
Figure of eight bearing is provided with oil groove 41 (see figure 3)s that link to each other with oil sucting cavity with axis hole with a side plane of the plane side combination of driving and driven gear, so that driving and driven gear shaft 5,7 is lubricated, reduces the wearing and tearing between axle and the hole.
Its working principle: shelves lid 6 outer driving gear shafts 5 are connected with motor output shaft before stretching out the pump housing, provide power by the motor oil feed pump, hydraulic oil is sent in the oil sucting cavity 10 that the curved surface by the waist of approximate " V " shape of pump housing inner chamber and figure of eight bearing outside surface and driving and driven gear 8,9 forms by oil inlet hole 31 by the hydraulic pressure kettle, through driving and driven meshed transmission gear, hydraulic oil pressure is delivered to pumping cavity 11, the hydraulic oil that enters pumping cavity flows out through oil outlet 32, thereby finishes the pump functional oil.
