Abstract
A magnetic shoe fixation structure used for permanent-magnetic generators belongs to the manufacturing technical field of the generator accessory component and comprises a shell (1), a magnetic shoe (9) disposed inside the shell (1) and a magnetic shoe fixation frame (2) disposed between the shell (1) and the magnetic shoe (3). The magnetic shoe fixation frame (2) is interference engaged with the shell (1). While assembling, the magnetic shoe coated with high intensity structural adhesive is disposed on the magnetic shoe fixation frame and the magnetic shoe together with the magnetic shoe fixation frame is pressed inside the shell. The magnetic shoe fixation structure has the characteristics of reasonable design, prevents the moving and falling of the magnetic shoe along the axial and radial directions, greatly resolves the quality and safety potential hazards resulted from the magnetic shoe falling and fundamentally improves the reliability of the system which plays a more effective role in the generators with super high requirements for the reliability (such as the ABS generator in the automobile anti-locking system).
Description
Technical field
The utility model relates to a kind of magneto magnetic shoe fixed structure, belongs to the manufacturing technology field of electric drilling match parts.
Background technology
At present, known magnetic shoe and housing fixing means are by being coated with structure glue at magnetic shoe and housing matching surface.The processing of generally will cleaning, deoil housing before being coated with structure glue, employed structure glue is generally A, B bi-component, and A, B, C three components are also arranged.Because being exposed to be easy in the air solidify, structure glue lost efficacy, so AB glue or ABC glue must matching while using (preparing according to a certain percentage as requested), at first, the ratio of preparation is difficult for grasping, secondly two or three components can not guarantee to mix fully, if adding housing and magnetic shoe cleans badly, just be difficult to guarantee the secure fit of magnetic shoe and housing, will be in motor operation course, owing to the motor feels hot, vibration causes magnetic shoe to come off, will be more serious under the situation of Fraquent start, frequent rotating, big electric current, big torque.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the magneto magnetic shoe fixed structure of system reliability.
The utility model is a magneto magnetic shoe fixed structure, comprises housing, places the magnetic shoe in the housing, it is characterized in that being provided with between housing and the magnetic shoe magnetic shoe fixed mount.During assembling, magnetic shoe is put on the magnetic shoe fixed mount after coating high strength structural adhesion, and magnetic shoe and magnetic shoe fixed mount together are pressed into housing.
Can be interference fit between described magnetic shoe fixed mount and the housing.
The utility model is reasonable in design, in order to overcome potential safety hazard and the not high deficiency of system reliability that magnetic shoe comes off, magnetic shoe and magnetic shoe fixed mount together is pressed into housing, and magnetic shoe is played dual fixedly protective effect.Guarantee that magnetic shoe axially, radially do not move, does not come off.Even magnetic shoe because of certain reason appearance cracking, damage, can not wiped with armature (for permanent magnet direct current motor) or stator (for brushless DC motor) generation mutually yet and cause shutdown, scaling loss etc. unusual.Solved the quality that magnetic shoe comes off, potential safety hazard well, fundamentally improved the reliability of system, this more has significant effect in the extra high motor of reliability requirement (the ABS motor that uses in as anti-locking system for car).

Fig. 2 is an overall structure stereogram of the present utility model.
Embodiment
The utility model places the magnetic shoe 3 in the housing 1 mainly by housing 1, places the formations such as magnetic shoe fixed mount 2 between housing 1 and the magnetic shoe 3, is interference fit between magnetic shoe fixed mount 2 and the housing 1.During assembling, magnetic shoe 3 is put on the magnetic shoe fixed mount 2 after coating high strength structural adhesion, and magnetic shoe fixed mount 2 and housing 1 interference fit together are pressed into housing 1 with magnetic shoe 3 and magnetic shoe retainer 2, guarantees that magnetic shoe 3 axially, radially do not move, does not come off.
Claims (2)
1, a kind of magneto magnetic shoe fixed structure comprises housing (1), places the magnetic shoe (3) in the housing (1), it is characterized in that being provided with magnetic shoe fixed mount (2) between housing (1) and the magnetic shoe (3).
2,, it is characterized in that being between described magnetic shoe fixed mount (2) and the housing (1) interference fit by the described magneto of claim 1 magnetic shoe fixed structure.
