Description
Technical field
The present invention relates to motor casing field more particularly to a kind of magnetic steel anti-shedding motor casings.
Background technology
It is understood that motor casing is an important component of motor, motor casing is not only wanted to play
The effect for protecting motor inner components, also needs to have preferable heat-sinking capability, can in time generate casing internal
Outside heat transfer to casing, motor is avoided to be burnt out or the generation of enameled wire depainting phenomenon because heated.Motor generally comprises fixed
Son, rotor and other electric machine assemblies are constituted；The stator of wherein permanent magnet direct current motor is made of casing and magnet steel, and magnet steel is general
By A/B glue stickings on the inner wall of casing.Existing motor casing mostly use it is columnar structured, magnet steel is also by two pieces
The opposite permanent magnet group of magnetic pole at；But in motor process of manufacture, we often have found the exradius ruler of magnet steel
Very little with casing internal diameter size is inconsistent, so the two side walls of magnet steel is caused to be " sticking up ", the outer wall of magnet steel without
Method is bonded completely with the inner wall of casing；The bonding plane size of magnet steel and casing depends on the interior section size of the two, this is in motor
It is very dangerous during use from now on：The glue of adhesive magnetic steel is easy to heated and prolonged use aging and motor
Be highly susceptible in use external impact and for a long time vibrate, these can all cause falling off for magnet steel, cause motor without
Method normal work is even damaged；Also it is exactly magnet steel when be bonded with casing, the glue of bonding often slime flux everywhere not only causes
The waste of glue and the aesthetic measure for having an effect on housing cavity.
The invention discloses a kind of magnetic steel anti-shedding motor casings thus, by being provided with magnet steel fastening in the inner cavity of motor casing
Magnet steel is fixed and protected to device, considerably increases the contact area of magnet steel and casing, effectively prevents falling off for magnet steel；This hair
The characteristics of bright to have security performance high, service life is long, and bonding magnetic steel is secured, saving glue resource.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of magnetic steel anti-shedding motor casings, to solve
The technical problems such as motor casing in the prior art is insecure with bonding magnetic steel, and usage safety performance is low, and motor service life is short；For
The above technical problem is solved, the invention discloses following technical schemes；
The invention discloses a kind of magnetic steel anti-shedding motor casing, including circular tube shaped shell and two pieces it is opposite polarity arc-shaped
Magnet steel, two blocks of opposite polarity magnet steel, which are relatively fixed, to be also oppositely arranged on the inner cavity of shell, the inner wall of shell there are two magnet steel
Clamp device, the strip-shaped clamp groove that magnet steel clamp device is mutually parallel by two form, and the bayonet position of two strip-shaped clamp grooves
In on same arc surface, and the bayonet of two strip-shaped clamp grooves is formed by the cambered surface ruler of arc sizes size and arc-shaped magnet steel
Very little equal in magnitude, two blocks of opposite polarity arc-shaped magnet steel are separately mounted in two magnet steel clamp devices；Pass through strip-shaped clamp groove
Not only the two side walls of magnet steel can be coated but also strip-shaped clamp groove is but also the increase of the contact area of magnet steel and shell, carries
High stability in use.
Further, it in order to preferably play the purpose of bonding, fixed magnet steel, is further opened on the inner wall of shell straight
Line groove, straight-line groove is located at two strip-shaped clamp grooves and is formed by among cambered surface, and shell is extended at the top of straight-line groove
Top surface, the bottom of straight-line groove is concordant with the bottom of strip-shaped clamp groove.It is past after installing magnet steel and magnet steel clamp device
Glue is added dropwise in straight-line groove, glue is in straight-line groove after dry glue, so that it may the magnet steel face tangent with casing to be fixed；
And glue is not easy to overflow straight-line groove, substantially increases the aesthetic measure of casing.
Further, in order to preferably be positioned to magnet steel, the inner cavity of shell is additionally provided with limiting plate, and limiting plate is located at
The bottom of straight-line groove, limiting plate are vertically arranged with straight-line groove.Limiting plate can also intercept the glue of extra spilling,
Glue slime flux everywhere is avoided, aesthetic measure is influenced.
Further, it the side wall of magnet steel is fixed, installs to preferably facilitate, strip-shaped clamp groove uses organic silica gel
Material is made；Organic silica gel material has preferable flexibility, magnet steel can be facilitated to install；Organic silica gel material also has higher
Temperature tolerance, weatherability and splendid electrical insulation properties, will not influence the normal use of motor.
Further, in order to save the use of glue, the groove depth of straight-line groove is 0.5~2cm.
Further, in order to preferably casing be facilitated to place, the bottom of shell is additionally provided with pedestal.
The invention discloses a kind of magnetic steel anti-shedding motor casings, by being provided with magnet steel clamp device in the inner cavity of motor casing
Magnet steel is fixed and protected, the contact area of magnet steel and casing is considerably increased, effectively prevents falling off for magnet steel；The present invention has
There is security performance high, service life is long, and bonding magnetic steel is secured, the characteristics of saving glue resource.
