Description
Technical field
The utility model relates to a kind of motor, and more particularly, it relates to a kind of Oil pump electrical machinery.
Background technology
Oil pump electrical machinery is a kind of particular motor driving oil pump, comprise motor body, front end housing and take-off (propeller) shaft, front end housing is offered with stepped bore, export in transmission retraction power transmission shaft, it is the axle of a hollow, matching with the external diameter of the input shaft of oil pump in axis hole aperture, has keyway at the spindle nose of take-off (propeller) shaft.
At present, on market Oil pump electrical machinery waterproof effect all very poor, major part does not all adopt encapsulation process, even if employ sealing ring, sealing effectiveness is also not obvious, once have seepage to Oil pump electrical machinery, just parts can be made to get rusty, affect the work of motor normal table.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Special-purpose motor for oil pump, adopts special encapsulation process, makes that Oil pump electrical machinery can waterproof be non-leakage completely, ensures the running of motor normal table.
For achieving the above object, the utility model provides following technical scheme: a kind of Oil pump electrical machinery, comprise motor body, front end housing and take-off (propeller) shaft, lug boss is provided with at the bottom of described front end housing lid, the outer surface of described lug boss and the contacted inner surfaces of motor body touch, and described motor body and the inconsistent end face of lug boss are provided with chamfering, and described chamfering and front end housing form confined space, be provided with O type circle in confined space, and described O type circle all with lug boss and chamfering inconsistent.
By adopting technique scheme, described motor body inner surface is provided with chamfering in described lug boss and motor body junction, and chamfering is provided with O type circle, and two of described lug boss vertical planes and described chamfering cross section all fit tightly with described O type circle.Improve traditional pattern that sealing ring is set at junction outer surface, when described lug boss is embedded into described motor body inner surface, make described O type circle in the state of compression, conflict mutually in described O type circle and adjacent three faces, contact area is larger, impel together with described lug boss more fits tightly with motor body inner surface, waterproof effect is more obvious.
The utility model is set to further: described front end housing caping is connected with the flange matched with oil pump.
By adopting technique scheme, the input shaft of oil pump is connected with described take-off (propeller) shaft by keyway, and flange bonded to each other is fastenedly connected.Improve traditional Oil pump electrical machinery and be connected with shaft coupling the pattern realizing transmission of power by a link with oil pump, changing from indirect power transmission becomes direct driving force transmission, and simplify complicated connected mode, transmission effect is better, has saved cost.
The utility model is set to further: described take-off (propeller) shaft spindle nose is provided with keyway, and described keyway is spline.
By adopting technique scheme, improve the mode that traditional flat key connects, axle and hub bore are provided with more tooth and groove, therefore stressed evenly, and spline is compared with flat key, spline is more shallow, and tooth root place stress is concentrated less, so the strength reduction of axle and hub is less, for transmitting the better effects if of cooperation.
The utility model is set to further: described take-off (propeller) shaft axle tail is provided with waterproof outside framework oil seal.
By adopting technique scheme, can prevent the lubricating oil in described take-off (propeller) shaft outer bearing from spilling, also further anti-sealing, dust can invade in bearing, making the running that axle is more stable.

In figure: 1, motor body; 2, front end housing; 3, take-off (propeller) shaft; 4, lug boss; 5, chamfering; 6, spline; 7, O type circle; 8, flange; 9 waterproof outside framework oil seals.
Embodiment
Referring to figs. 1 through Fig. 4, the utility model Oil pump electrical machinery embodiment is described further.
A kind of Oil pump electrical machinery, comprise motor body 1, front end housing 2 and take-off (propeller) shaft 3, described front end housing 2 covers the end and is provided with lug boss 4, the outer surface of described lug boss 4 and the contacted inner surfaces of motor body 1 touch, described motor body 1 end face inconsistent with lug boss 4 is provided with chamfering 5, described chamfering 5 forms a confined space with front end housing 2, is provided with O type circle 7 in confined space, and described O type circle 7 is all inconsistent with lug boss 4 and chamfering 5.
By adopting technique scheme, described motor body 1 inner surface is provided with chamfering 5 in described lug boss 4 with motor body 1 junction, chamfering 5 is provided with O type circle 7, and two of described lug boss 4 vertical planes and described chamfering 5 cross section all fit tightly with described O type circle 7.Improve traditional pattern that sealing ring is set at junction outer surface, when described lug boss 4 is embedded into described motor body 1 inner surface, make the state of described O type circle 7 in compression, described O type circle 7 is conflicted mutually with adjacent three faces, contact area is larger, impel together with described lug boss 4 more fits tightly with motor body 1 inner surface, waterproof effect is more obvious.
Described front end housing 2 caping is connected with the flange 8 matched with oil pump.
As another kind of execution mode, Oil pump electrical machinery can realize transmission of power by a link and shaft coupling and oil pump, considers that to make structure so more complicated, increase production cost, and indirect power transmission, the concentricity of diaxon is poor, frictional force is comparatively large, makes the lifetime of axle.Therefore the present embodiment is preferred, described front end housing 2 caping is connected with the attachable flange 8 that to match with oil pump.Like this, the input shaft of oil pump is connected with described take-off (propeller) shaft 3 by keyway, and flange 8 place bonded to each other is fastenedly connected.Change from indirect power transmission and become direct driving force transmission, simplify complicated connected mode, transmission effect is better, has saved cost.
Described take-off (propeller) shaft spindle nose is provided with keyway, and described keyway is spline 6.
As another kind of execution mode, described keyway also can be set to flat key, and the flat key load diatibution of consideration is uneven, and bearing capacity is less.Therefore the present embodiment is preferred, described keyway is set to spline 6.Like this, because axle and hub bore are provided with more tooth and groove, thus stressed evenly, and spline is compared with flat key, and spline 6 is more shallow, and tooth root place stress is concentrated less, so the strength reduction of axle and hub is less, for transmitting the better effects if of cooperation.
The utility model is set to further: described take-off (propeller) shaft 3 axle tail is provided with waterproof outside framework oil seal 9.
By adopting technique scheme, can prevent the lubricating oil in described take-off (propeller) shaft 3 outer bearing from spilling, also further anti-sealing, dust can invade in bearing, making the running that axle is more stable.
