Description
Technical field
The present invention relates to a kind of power takeoff, a kind of power takeoff with self lubricating pump, belongs to power takeoff technical field specifically.
Background technology
Along with economic development, application and the demand of special-purpose vehicle constantly improve.Vehicle class is constantly updated and regenerates.The transformation of special-purpose vehicle is just proposed higher requirement by this.Mostly current most of special-purpose vehicle is to use power takeoff to carry out power taking output, enables the vehicle to carry out operation under special state, efficiently accomplishes all kinds of instructions for use.Power takeoff is a kind of instrument to moment of torsion transmission, is operationally often under the operating mode of high rotating speed high capacity, and the lubricating requirement of parts each in power takeoff is higher.If electromotor and change speed gear box internal gear oil can trickle naturally into power takeoff when power takeoff is installed, when power takeoff works, fluid can be splashed to the rotation of gear in power takeoff and be lubricated and cool down on a parts.If but electromotor and change speed gear box internal gear oil can not trickle into power takeoff naturally when power takeoff is installed, then must power takeoff be cooled down an external road binders liquid.And now major part occasion is all arrange a hydraulic pump outside power takeoff to realize the circulation of fluid.Which not only adds cost, complicated system, also to spend a lot of energy to go to solve the power source problem of hydraulic pump.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, thus providing a kind of power takeoff with self lubricating pump, hydraulic pump and power takeoff being combined, meet lubrication and cooling requirement during power takeoff work.
According to technical scheme provided by the invention, power takeoff with self lubricating pump includes casing, it is characterized in that: driven gear is arranged in casing side by the bearing at two ends, splined shaft is arranged in casing opposite side by bearing, is provided with the driving gear engaged with driven gear in casing.Connecting blade spline housing on splined shaft, blade spline housing connects rotor by pin, rotor outer ring is provided with the stator being fixed on cabinet wall.Connecting gear spline set on splined shaft, gear spline set outer ring is provided with promoting the piston of gear spline set axially-movable, is provided with back-moving spring between piston and driven gear.Driven gear one end is provided with driven gear external splines, and gear spline overlaps one end and is provided with and driven gear external splines meshed gears spline housing internal spline.
Further, driving gear is positioned at above driven gear.
Further, wall box is provided with fuel feed hole.
Further, it is provided with oil outlet bottom stator.
Further, the blade rotated with rotor it is provided with between rotor and stator.
Compared with the prior art the present invention has the advantage that
Present configuration is simple, compact, reasonable, carries lubricating pump, meets lubrication and cooling requirement during power takeoff work, it is not necessary to external oil circuit；Novel structure, integrated level is high, and assembly volume is little, lightweight；It is applicable to the occasion without external lubrication, expands power takeoff and use scope.

Detailed description of the invention
The present invention will be further described in conjunction with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the invention mainly comprises casing 1, driven gear 3 is arranged on side in casing 1 by the bearing at two ends, and splined shaft 10 is arranged on opposite side in casing 1 by bearing.Being provided with the driving gear 2 engaged with driven gear 3 in casing 1, driving gear 2 is positioned at above driven gear 3.
Connecting blade spline housing 9 on splined shaft 10, blade spline housing 9 connects rotor 8 by pin 11, rotor 8 outer ring is provided with the stator 7 being fixed on casing 1 inwall, is provided with the blade 12 rotated with rotor 8 between rotor 8 and stator 7.
Described casing 1 sidewall is provided with fuel feed hole 13, is provided with oil outlet 14 bottom stator 7, when rotor 8 band moving vane 12 rotates, from fuel feed hole 13 inspiration gear oil, enters casing 1 by the oil outlet 14 bottom stator 7 and parts each in power takeoff are lubricated.
Connecting gear spline set 6 on splined shaft 10, gear spline overlaps the piston 5 that 6 outer rings are provided with promoting gear spline to overlap 6 axially-movables, is provided with back-moving spring 4 between piston 5 and driven gear 3.Driven gear 3 one end is provided with driven gear external splines 15, and gear spline overlaps 6 one end and is provided with and driven gear external splines 15 meshed gears spline housing internal spline 16.
The operation principle of the present invention is: during work, and driving gear obtains moment of torsion from change speed gear box and drives driven gear to rotate.When passing into compression air, piston driving spline housing compression reseting spring engages to driven gear side shifting, driven gear external splines 15 and gear spline set internal spline 16 together, and gear spline set is followed driven gear and rotated.Gear spline set drives splined shaft to rotate simultaneously, and splined shaft band moving vane spline housing rotates, and blade spline housing is rotated by pin rotor driven and blade.Stator, rotor, blade composition vane pump, realizes entering inside power takeoff from fuel feed hole oil suction to oil-out oil extraction under splined shaft rotates and drives, for lubricating the effect of a parts in power takeoff.
The present invention inherits original construction features the design by optimizing, rational layout, hydraulic pump and power takeoff are combined, and combines integral, easy to use, widely applicable, it is possible to improve the application operating mode of power takeoff and increase the use scope of power takeoff.
