The caducous problem of steel bar, but magnet steel item can not prevent to pacify completely there are still the possibility being sliding out from rotor rim both ends
Full hidden danger.Thus applicant has carried out design again on rotor mounting structure, to improve aforementioned schemes.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of novel permanent magnet motor rotor mounting structure.
The utility model solves technical solution used by its technical problem are as follows:
A kind of novel permanent magnet motor rotor mounting structure, including rotor rim, the magnet steel item being mounted thereon and support knot
Structure, the rotor rim outer surface offer several keyways, and the magnet steel installation by adhering is in keyway, the support construction
It is fixed on the rotor rim inner surface, the keyway is axial along rotor rim and sets, and longitudinal section is in up-narrow and down-wide shape,
The magnet steel item is mutually fitted with keyway shape, and the support construction includes bearing holder (housing, cover) and several supporting ribs being fixed thereon, described
The bearing holder (housing, cover) at support construction both ends protrudes from the rotor rim two sides, is provided with thread fixing structure on outer surface, and lead to
It crosses thread fixing structure and position-arresting disk is installed, the radial height of the position-arresting disk is located at the keyway above and below between, to key
Magnet steel item in slot forms axial limiting.
Further, the position-arresting disk and the direction that is screwed of bearing holder (housing, cover) are opposite with rotor rotation direction.
Further, it is provided with the internal screw thread with thread fixing structure cooperation in the position-arresting disk inner circle, is gone back on position-arresting disk
It is provided with several radiator windows.
Further, the keyway longitudinal section is in isosceles trapezoid.
Further, the base angle of the isosceles trapezoid is 83 °~85 °.
Further, axisymmetricly major arc shape, correspondence install cylindrical magnet steel item for the keyway longitudinal section.
