Embodiment

Embodiment 1

The residual gear machine of the utility model is to realize like this, do below in conjunction with Fig. 1, Fig. 2 and to specify, residual gear machine is made up of: shaftgear 1, gear 2, end cap 3, body 4, end cap 5, screw 6, pin 7, flowing medium inlet 8, flowing medium row mouthfuls 9, the diameter of axle support of shaftgear 1 and gear 2 is in the axis hole of end cap 3 and end cap 5, end cap 3 and end cap 5 are bound up on the body 4 by pin 7 and screw 6, realize rotating relative to engagement.Tooth body on shaftgear 1 gear ring except that have two complete, all the other have all cut gap becomes residual tooth, the degree of depth of gap is not more than addendum.Gear 2 leaves 3 complete teeth, and all the other also all are processed into the residual tooth of gap.Stay several complete teeth as for each gear, can determine as required.On body 4, be provided with flowing medium inlet 8 and flowing medium row mouth 9.

When using as pump, outer moment is imported into by shaftgear 1 outer Shen axle, shaftgear 1 is moved in the direction of the clock, and by the engagement driven gear 2 rotate counterclockwise, fluid this moment (gas, liquid) sucks from the medium inlet, released along a circumferential medium row mouthful direction pressurization in the body by complete tooth, and the conversion of realization mechanical energy, this working principle is identical with existing gear pump.But this machine is because the existence of residual tooth communicates the between cog of each residual tooth, thereby the space of expansion flowing medium in machine only do not limit medium within each between cog and do not resemble existing gear pump, so it not only is suitable for liquid medium, is suitable for gas medium yet.And existing gear pump, only suitable liquid medium promptly is used in liquid medium, because the increasing of the interior space, efficient has also improved.When as prime mover, flowing medium is pressed into from the medium inlet high pressure, complete tooth body by each residual tooth gap pushing shaft gear 1 moves in the direction of the clock, promote gear 2 simultaneously by counterclockwise rotating, up to getting rid of from medium row mouth, complete tooth body returns the place, medium inlet, just finishes a work cycle.Can be to the conversion of rotary mechanism energy thereby realize by the pressure of fluid, the outrigger shaft of shaftgear 1 is exactly the output terminal of conversion back rotary mechanism energy.
