Abstract
The invention discloses a structure for installing non non-magnetic or weak-magnetic tiles of a motor stator. The structure comprises an outer shell of the motor stator and the magnetic tiles attached to the inner wall of the outer shell, and the part between the magnetic tiles and the inner wall of the outer shell is coated with adhesive. The structure is characterized in that an expandable inner support is arranged inside an inner cavity of the outer shell, and the expandable inner support is used for providing force for the magnetic tiles to press the inner wall of the outer shell tightly. An installation method based on the installation structure comprises the first step of coating the outer arc faces of the two magnetic tiles with the adhesive, the arc faces are oppositely attached to the inner wall of the outer shell of the motor stator, the second step of placing the expandable inner support between the two opposite magnetic tiles to enable the inner support to expand and squeeze the magnetic tiles, and the third step of taking out the inner support after the magnetic tiles and the outer shell are bonded firmly. External force is exerted to the non-magnetic or weak-magnetic tiles through the inner support to enable the magnetic tiles to press the inner wall tightly. The defect that bonding force is not large enough when the magnetic files are assembled is overcome, the effect of glue is effectively achieved, and the bonding strength between the magnetic tiles and the outer shell of the motor stator is guaranteed.
Description
Technical field
The present invention relates to motor and manufacture field, relate in particular to a kind of motor stator without magnetic or weak magnetic magnetic shoe mounting structure and installation method.
Background technology
Magnetic shoe is a kind of in permanent magnet, mainly is used in watt shape magnet on magneto.From electromagnetic motor, to produce the magnetic potential source by magnet exciting coil different, and magneto is to produce constant magnetic potential source with permanent magnetic material.Permanent magnetic tile replaces electric excitation to have lot of advantages, can make that electric machine structure is simple, easy to maintenance, lightweight, volume is little, use is reliable, copper consumption is few, copper loss is low, energy consumption is little etc.
Magnetic shoe has three kinds of commonly used modes that magnetize usually, and magnetic shoe magnetizes separately, reinstalls casing, and then assembling is whole; Perhaps the magnetic shoe casing (gluing) of packing into magnetizes again, and then assembling is whole; Perhaps the magnetic shoe casing (gluing) of packing into, refill and prepare finished product, and last integral body magnetizes.For the latter two mode that magnetizes, all first by powerful anaerobic type glue, will to be bonded together without magnetic shoe and the stator casing of magnetic or weak magnetic, because of such magnetic shoe without magnetic or weak magnetic, active force deficiency when bonding, magnetic shoe can not very closely fit in the motor stator casing inwall, have gap, and anaerobic adhesive contacts with air and can't solidify, cause motor stator magnetic shoe bonding strength not reach instructions for use.
Summary of the invention
The technical problem to be solved in the present invention is to overcome defect of the prior art, provide a kind of motor stator of effectively realizing magnetic shoe and motor stator inwall close adhesion without magnetic or weak magnetic magnetic shoe mounting structure and installation method.
For addressing the above problem, a kind of motor stator of the present invention without magnetic or weak magnetic magnetic shoe mounting structure, comprise the shell of motor stator and be fitted in the magnetic shoe on described outer casing inner wall, scribble adhesive between described magnetic shoe and outer casing inner wall, it is characterized in that, also be provided with and can expand the formula inner support in the inner chamber of described shell, this can expand the formula inner support and offer the power that described magnetic shoe compresses described outer casing inner wall.
Described magnetic shoe is two, and the described formula inner support that expands acts on described two magnetic shoes simultaneously.
The described shape and the corresponding setting of the shape of described magnetic shoe intrados that expands formula inner support extrados.
Describedly expand formula inner support extrados and the contacted part of described magnetic shoe intrados is provided with elastomeric element.
A kind of motor stator without magnetic or weak magnetic magnetic shoe installation method, comprise the following steps:
1) by after two magnetic shoe extrados application of adhesive, relatively be affixed on the outer casing inner wall of motor stator;
2) put into and can expand the formula inner support between two relative magnetic shoes, make the described magnetic shoe of inner support expanding extruding, make the stressed compression outer casing inner wall of magnetic shoe, the adhesive rear abundant diffusion that is squeezed, gapless between magnetic shoe and shell;
3) magnetic shoe and shell bonding firmly after, take out inner support.
A kind of motor stator of the present invention without magnetic or weak magnetic magnetic shoe mounting structure and installation method, by inner support, the magnetic shoe without magnetic or weak magnetic is added to external force, can compress inwall, the hypodynamic defect of adhesive effect while having solved the assembling of the type magnetic shoe, effectively bring into play the bonding effect of glue, guaranteed the bonding strength of magnetic shoe and motor stator casing.Of the present invention simple in structure, facilitate easyly, effectively avoided motor stator magnetic shoe bonding strength in the prior art not reach the defect of instructions for use, improve the useful life of motor, reduce failure rate.
The accompanying drawing explanation
The schematic diagram without magnetic or weak magnetic magnetic shoe mounting structure that Fig. 1 is motor stator of the present invention.
