Abstract
The utility model discloses a kind of rotor leveling structure, comprise main shaft, location division, connecting portion, iron core, plastic sheath, levelling groove, main shaft is socketed with in described iron core, main shaft stretches out iron core and forms location division and connecting portion, connecting portion is processed with locating surface, iron core overcoat has plastic sheath, and core portion exposes plastic sheath, and iron core exposes plastic sheath position and has some levelling grooves.Described main shaft both ends are all processed with annular chamfer.Described iron core is cylindrical.Main shaft both ends of the present utility model are all processed with annular chamfer, can not interfere and wearing and tearing when iron core rotates, rotate smooth and easy, impeller is arranged on connecting portion, makes impeller firm position by locating surface, can not offset, gravity difference according to iron core surrounding has levelling groove, makes iron core surrounding gravity identical, can stable equilibrium more in later stage actual use procedure, can not wear and tear, long perfomance life.
Description
Technical field
The utility model relates to the technical field of automobile fuel pump, particularly a kind of rotor leveling structure.
Background technology
Fuel pump operationally needs rotor impeller to be carried by fuel oil, rotor needs two ends just can make in the hole of location, and rotor can be stable rotates when rotating, the surrounding of processed rotor out due to the different gravity of density also different, because rotor requires very high when rotating, so general rotor there will be the problem of side serious wear in use for some time, and impeller is installed also insecure.
Utility model content
For solving the problem, the purpose of this utility model be to provide a kind of structure simple, the rotor leveling structure that rotor surrounding gravity is identical, slow-roll stabilization, Long-Time Service can not wear and tear, be connected firmly can be made.
For achieving the above object, the technical solution of the utility model:
A kind of rotor leveling structure, comprise main shaft, location division, connecting portion, iron core, plastic sheath, levelling groove, main shaft is socketed with in described iron core, main shaft stretches out iron core and forms location division and connecting portion, connecting portion is processed with locating surface, iron core overcoat has plastic sheath, and core portion exposes plastic sheath, and iron core exposes plastic sheath position and has some levelling grooves.
As preferably, described main shaft both ends are all processed with annular chamfer.
As preferably, described iron core is cylindrical.
Main shaft both ends of the present utility model are all processed with annular chamfer, can not interfere and wearing and tearing when iron core rotates, rotate smooth and easy, impeller is arranged on connecting portion, makes impeller firm position by locating surface, can not offset, gravity difference according to iron core surrounding has levelling groove, makes iron core surrounding gravity identical, can stable equilibrium more in later stage actual use procedure, can not wear and tear, long perfomance life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of rotor leveling structure, comprise main shaft 1, location division 2, connecting portion 3, iron core 5, plastic sheath 6, levelling groove 7, main shaft 1 is socketed with in described iron core 5, main shaft 1 stretches out iron core 5 and forms location division 2 and connecting portion 3, and connecting portion 3 is processed with locating surface 4, iron core 5 overcoat has plastic sheath 6, iron core 5 part exposes plastic sheath 6, and iron core 5 exposes plastic sheath 6 position and has some levelling grooves 7.Described main shaft 1 both ends are all processed with annular chamfer.Described iron core 5 is cylindrical.Main shaft 1 both ends of the present utility model are all processed with annular chamfer, can not interfere and wearing and tearing when iron core 5 rotates, rotate smooth and easy, impeller is arranged on connecting portion 3, makes impeller firm position by locating surface 4, can not offset, have levelling groove 7 according to the gravity difference of iron core 5 surrounding, make iron core 5 surrounding gravity identical, can stable equilibrium more in later stage actual use procedure, can not wear and tear, long perfomance life.
