Abstract
The utility model discloses a motor rotor of an electric oil delivery pump. The motor rotor comprises an armature shaft, wherein a carbon commutator and an armature core which consists of laminated silicon steel sheets are sleeved on the armature shaft; the silicon steel sheets are provided with ribs which spread from the center to the periphery; the end parts of the ribs are provided with armature tooth end sheets; the ribs and the armature tooth end sheets form T-shaped structures; and gaps with large tops and small bottoms are formed between adjacent ribs. The key points are that: the end parts of the armature tooth end sheets are provided with bevel edges which tilt downwards; the rotor also comprises a winding wedge; the winding wedge comprises a top cover; one end of the top cover is provided with a driving claw, and sealing strips with the same number of the gaps are arranged on the other side of the top cover; the sections of the sealing strips have trapezoidal structures corresponding to the end parts of the armature tooth end sheets; the sealing strips of the winding wedge are inserted into the gaps; and a sealing structure is formed on the outer surface of the armature core. According to the motor rotor, the winding wedge which can be independently disassembled and assembled is used for sealing the gaps on the armature core, so that the mounting is facilitated, meanwhile, a turning step in the original process is saved, the cost is reduced, and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of electrically operated fuel pump motor, relates in particular to rotor structure wherein.
Background technology
Oil pump electrical machinery is parts commonly used on the automobile, after the energising, fuel oil is sucked from oil-in, and the inside of the electrically operated fuel pump of flowing through extrudes from oil-out again, gives the fuel system fuel feeding.
The Oil pump electrical machinery structure is made up of the pump housing, permanent magnet and shell three parts.Fixing main pole and brush are installed on the stator of brush motor, armature winding and commutator are installed on the rotor.The electric energy of DC power supply gets into armature winding through brush and commutator, produces armature supply, and magnetic field that armature supply produces and main field interact and produce electromagnetic torque, make the dynamic load of motor rotating band.
Rotor comprises that armature shaft, carbon commutator, inside have the armature core of winding, armature core is made up of the stack of multi-disc silicon steel sheet; The center of silicon steel sheet has the hole; The periphery has rib; The end of rib is connected with the armature tooth dististyle, has up big and down small space between the adjacent rib, and winding passes the space and is wrapped on the rib.After the winding installation, use insulating material that the space is filled, the turning of going forward side by side makes the surface of armature core form smooth cylindrical surface.But this kind manufacture is comparatively complicated, after the space filling finishes, also need carry out turning to cylindrical surface and handle, and has increased manufacturing cost.
The utility model content
The purpose of the utility model provides the simple electrically operated fuel pump rotor of a kind of manufacturing process.
To achieve these goals, adopt following technical scheme: a kind of electrically operated fuel pump rotor comprises armature shaft; The armature core that is with carbon commutator on the armature shaft and forms by silicon steel sheet stack, wherein silicon steel sheet has the rib that mind-set is therefrom diffused all around, and the end of rib has the armature tooth dististyle; Rib and armature tooth dististyle form T shape structure, form up big and down small space between the adjacent rib, and it is characterized in that: the end of said armature tooth dististyle has the hypotenuse under being tilted to; Said rotor also comprises the winding wedge, and said winding wedge comprises top cover, and top cover one end is provided with driving claw; Opposite side is provided with the sealing strip with the space corresponding number; The cross section of sealing strip is and the corresponding trapezium structure in the end of armature tooth dististyle, and the sealing strip of winding wedge inserts in the space, at the outer surface formation hermetically-sealed construction of armature core.
As further optimization, sealing strip inserts in the space for ease, and the end of said sealing strip has the inclined plane.
The utility model use winding wedge of dismounting separately seals the space on the armature core, is convenient to install, and has omitted turning step in original technology simultaneously, has reduced cost, has improved production efficiency.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be further described.
Shown in figure 11, a kind of electrically operated fuel pump rotor comprises armature shaft 3; Be with carbon commutator 1 and armature core 2 on the armature shaft 3, armature core is made up of the stack of multi-disc silicon steel sheet, and the center of silicon steel sheet has the hole; The periphery have to around the rib 7 that diffuses, the end of rib has armature tooth dististyle 8, rib and armature tooth dististyle form T shape structure; Form up big and down small space between the adjacent rib, the end of said armature tooth dististyle has the hypotenuse 9 under being tilted to.Said rotor also comprises the winding wedge, and the winding wedge comprises top cover 5, and top cover one end is provided with driving claw 6; Opposite side is provided with the sealing strip 4 with the space corresponding number; The cross section of sealing strip is the corresponding trapezium structure of hypotenuse that forms with the end of armature tooth dististyle, and the sealing strip of winding wedge inserts in the space, forms hermetically-sealed construction at the outer surface of armature core; The end of sealing strip has inclined plane 10, so that insert in the space.
With electromagnetic torque transmission output, the three-jaw connector of winding wedge is connected with the pump housing rotor through the winding wedge
,Transmission of power is stable, and the life-span is long; When the winding wedge can prevent the rotor high-speed rotation simultaneously, the enamelled wire in the rotor core groove threw away, and causes product failure, thereby has improved reliability of products.The winding wedge is packed into behind the armature tooth dististyle, spline and winding wedge no-float, and this kind design makes that product processes obtains simplifying, assembling is simple, stability of transmission and reliability height.
