Abstract
Interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell（A）, rotor punching（1）And permanent magnet（2）, rotor punching（1）For whole stamping, there are permanent magnet inlaid hole, whole stamping in whole stamping（1）Hot jacket forms the permanent magnet inlaid hole after superposition, permanent magnet after entering in roller（2）It is inlaid in the permanent magnet inlaid hole after superposition and forms interior permanent magnets.Compared with prior art, of the invention to has the following advantages：1. punching entirety punching press is completed, after superposition, rear hot jacket enters in roller, avoids punching, and sheet punching press precision is high, and permanent magnet can ensure that not same pole permanent magnet does not deviate.Processing and assembly simplify more.2. the oxidation to permanent magnet is also greatly improved.Since permanent-magnet type shape is changed to cuboid processing simply, waste is saved.3. permanent magnet postpones in being changed to, rotor surface loss is reduced, efficiency is improved, meanwhile, it prevents magnetic pole surfaces temperature excessively high, avoids permanent magnet because of high temperature loss of excitation.
Description
Technical field
The present invention relates to a kind of mine explosion-suppression permanent magnetic electric barrel, especially a kind of interior permanent magnets mine explosion-suppression permanent magnetism
Motorized pulleys.
Background technology
Currently, the mine explosion-suppression permanent magnetic electric barrel of the prior art, permanent magnet are tiles, not only processing is complicated, wastes material
Material, it is of high cost；And permanent magnet leans against the threaded hole processed in cylinder shell and is fixed with bolt, the thread mill drilling in cylinder shell,
It is fixed by bolts, not only installation trouble, also occurs installation damage permanent magnet situation sometimes；And threaded hole positional precision controls
It is bad, cause permanent magnet not install, occur the case where same pole permanent magnetism solid offsetting after installation is complete and occur often.Because of permanent magnetism
Body directly it is exposed in air, it is poor to the oxidation protection of permanent magnet, directly acted on forever in motor course of work high temperature
On magnetic material, permanent magnet loss of excitation can be caused.Therefore, a kind of interior permanent magnets mine explosion-suppression permanent magnetic electric barrel is designed, is mesh
The preceding technical issues that need to address.
Invention content
Technical problem to be solved by the invention is to provide a kind of interior permanent magnets mine explosion-suppression permanent magnetic electric barrels.
The present invention the technical solution to solve the technical problem is that：
Interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell, rotor punching and permanent magnet, rotor punching are whole
Body stamping is formed after superposition forever after having permanent magnet inlaid hole, whole stamping hot jacket to enter in roller in whole stamping
Magnet inlaid hole, permanent magnet, which is inlaid in the permanent magnet inlaid hole after superposition, forms interior permanent magnets.
As a preferred embodiment of the present invention, the type shape of the permanent magnet is cuboid.
Compared with prior art, of the invention to has the following advantages：
1. punching entirety punching press is completed, after superposition, rear hot jacket enters in roller, avoids punching, sheet punching press precision is high, permanent magnet
It can ensure that not same pole permanent magnet does not deviate.To processing and assembling simplify more.2. the oxidation to permanent magnet also has significantly
Raising.Since permanent-magnet type shape is changed to cuboid processing simply, material is not wasting.3. permanent magnet postpones in being changed to, reduce
Rotor surface is lost, and improves efficiency, meanwhile, it prevents magnetic pole surfaces temperature excessively high, avoids permanent magnet because of high temperature loss of excitation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the structural schematic diagram of the prior art；
Fig. 3 is enlarged drawing at the I of figure.
Specific implementation mode
As shown, interior permanent magnets mine explosion-suppression permanent magnetic electric barrel, including cylinder shell A, rotor punching 1 and permanent magnetism
